rust esp32 esp-idf

esp-idf-sys's Introduction

Raw Rust bindings for the ESP IDF SDK

Highlights

Build is cargo driven and automatically downloads & configures everything by default; no need to download the ESP IDF SDK manually, or set up a C toolchain
Supports both native ESP IDF build (default), as well as a PlatformIO build
Option to use in a mixed Rust/C project. Check the documentation in the esp-idf-template crate

You might want to also check out the type safe Rust wrappes built on top of these raw bindings:

Note
esp-idf-sys's build script will download the esp-idf, its gcc toolchain, and build it. To show progress and build information about this process run cargo with the -vv (very verbose) flag, so that build script output is also displayed. This is especially useful since the initial build will take a while.

Build Prerequisites

Follow the Prerequisites section in the esp-idf-template crate.

Customizing how the ESP IDF SDK is built

Read the documentation here.

Examples

The examples could be built and flashed conveniently with cargo-espflash. To run e.g. std_basics on an e.g. ESP32-C3: (Swap the Rust target and example name with the target corresponding for your ESP32 MCU and with the example you would like to build)

with cargo-espflash:

$ MCU=esp32c3 cargo espflash flash --target riscv32imc-esp-espidf --example std_basics --monitor

MCU	"--target"
esp32c2	riscv32imc-esp-espidf
esp32c3	riscv32imc-esp-espidf
esp32c6	riscv32imac-esp-espidf
esp32h2	riscv32imac-esp-espidf
esp32p4	riscv32imafc-esp-espidf
esp32	xtensa-esp32-espidf
esp32s2	xtensa-esp32s2-espidf
esp32s3	xtensa-esp32s3-espidf

Setting up a "Hello, world!" binary crate with ESP IDF

Use the esp-idf-template project. Everything would be arranged and built for you automatically - no need to manually clone the ESP IDF repository.

esp-idf-sys's Issues

Include esp_tls.h header

Hello,
would it be possible to include the esp_tls.h header? I think this would be useful to be able to make https requests.

Best regards.

First 3 bytes of files read from FatFs will be truncated

Hi,
I have created a repro for this bug: https://github.com/derchr/repro-fs
Just follow the instructions in the readme and the bug should show up.

Description of the bug:
What I noticed is that somehow the first 3 bytes of all files that are being read from the filesystem get truncated.
I'm almost certain that 1-2 weeks ago this bug wasn't there as I remember loading binary files (images) from the fs and this worked flawlessly. Now always 3 bytes are missing and the image does not get parsed.
I'm also not sure if this is even caused by esp-idf-sys.

My toolchain is the esp rust compiler version 1.57.0 targeting the default ESP32.
In the example I use the master branch of esp-idf, but I also encountered the issue in the stable 4.4 version.

Thanks!

EDIT:
When using a fixed size array instead of Vec or String to read in the file, it actually works! String::with_capacity on the other hand does not work.

    use std::io::Read;
    let mut lorem = std::fs::File::open("/mnt/readme.txt").unwrap();
    let mut read: usize;
    let mut buf = [0u8; 512];
    read = lorem.read(&mut buf).unwrap();
    while read != 0 {
        println!("{}", std::str::from_utf8(&buf[..read]).unwrap());
        read = lorem.read(&mut buf).unwrap();
    }

`esp-idf-sys` fails to build

I have a project using the Rust ESP toolchain and today compilation of esp-idf-sys failed without any apparent changes. I've created an entirely new project from scratch using https://github.com/esp-rs/esp-idf-template and even that fails to compile with the exact same error:

Consider installing embedded Python on Windows

Python is not installed by default on Windows, and overall, the installation is a hassle.
Therefore, the ESP-IDF installation script (PowerShell) for Windows installs an embedded Python instance in the ~/.espressif directory.

We might do the same during the native cargo-first build when installing other stuff in the .espressif directory.
We might even consider doing this for the PlatformIO build, even though it is not completely clear where exactly the Python instance should be uncompressed then (in ~/.platformio?).

Assert when calling std::time::Instant::now()

I got such traceback using https://maximeborges.github.io/esp-stacktrace-decoder/ on ESP32.

I have little bit hard time understanding where things blew up.
So esp32rogue/src/ublox/mod.rs:56 calls my timer wrapper esp32rogue/src/ublox/timer.rs:15 which looks like:

use ublox_cellular::fugit;
use ublox_cellular::prelude::*;

pub struct SysTimer<const TIMER_HZ: u32> {
    description: String,
    monotonic: std::time::Instant,
    start: Option<std::time::Instant>,
    duration: fugit::TimerDurationU32<TIMER_HZ>,
}

impl<const TIMER_HZ: u32> SysTimer<TIMER_HZ> {
    pub fn new(description: &str) -> Self {
        Self {
            description: description.into(),
            monotonic: std::time::Instant::now(),
            start: None,
            duration: fugit::TimerDurationU32::millis(0),
        }
    }
}

impl<const TIMER_HZ: u32> Clock<TIMER_HZ> for SysTimer<TIMER_HZ> {
    type Error = std::convert::Infallible;

    fn now(&mut self) -> fugit::TimerInstantU32<TIMER_HZ> {
        let millis = self.monotonic.elapsed().as_millis();
        fugit::TimerInstantU32::from_ticks(millis as u32)
    }

    fn start(&mut self, duration: fugit::TimerDurationU32<TIMER_HZ>) -> Result<(), Self::Error> {
        self.start = Some(std::time::Instant::now());
        self.duration = duration.convert();
        log::debug!(
            "[{}] start {:?} duration {:?}",
            self.description,
            self.start,
            self.duration
        );
        Ok(())
    }

    fn cancel(&mut self) -> Result<(), Self::Error> {
        if self.start.is_some() {
            self.start = None;
        }
        Ok(())
    }

    fn wait(&mut self) -> nb::Result<(), Self::Error> {
        if let Some(start) = self.start {
            if std::time::Instant::now() - start > std::time::Duration::from_millis(self.duration.ticks() as u64) {
                log::debug!(
                    "[{}] now {:?} start {:?} duration {:?} {:?}",
                    self.description,
                    std::time::Instant::now(),
                    self.start,
                    self.duration,
                    std::time::Duration::from_millis(self.duration.ticks() as u64)
                );
                Ok(())
            } else {
                // this does not work yet
                // std::thread::yield_now();
                // use workaround
                unsafe { esp_idf_sys::vTaskDelay(1) };

                Err(nb::Error::WouldBlock)
            }
        } else {
            Ok(())
        }
    }
}

Line 15 is monotonic: std::time::Instant::now(),. If I understood it correctly calling this actually caused assert and panic in the end.

Notice that three SysTimer instances were created from different threads.

Decide tools installation directory

pio uses the platformio default in ~/.platformio
Should both strategies use the same directory (e.g. <?>/.embuild/platformio for pio and <?>/.embuild/espressif for native)?
Where should the default directory be: home, workspace or out directory?

@ivmarkov already enumerated options with pros and cons:

That is to say, whatever we decide to be the default, it should be for both build systems. To summarize, perhaps 4 options:

Option 1 - install and use the default global locations (i.e. ~/.platformio and ~/.espressif)

Pros:

Does not pollute the binary crate with stuff that should be .gitignore-d

Downloaded toolchains etc. can be re-used across builds of different binary crates

Already downloaded toolchains etc. will just be used

Cons:

Patching ESP-IDF by the build itself is not so ideal as this is kinda build-specific

Messes up with the global user configuration of either PlatformIO or Espressif idf.py

Option 2 - install and use an embuild-specific global location (i.e. ~/.embuild/platformio and ~/.embuild/espressif)

Pros:

Does not pollute the binary crate with stuff that should be .gitignore-d

Downloaded toolchains etc. can be re-used across builds of different binary crates

Already downloaded toolchains etc. will just be used

Does not mess up with the user configuration

Cons:

Patching ESP-IDF by the build itself is not so ideal as this is kinda build-specific

Creates something outside the binary crate directory

Option 3 - install and use an embuild-specific location within the root of the binary crate (i.e. .embuild/platformio and .embuild/espressif)

Pros:

Does not mess up with the user configuration

No global state

Patching ESP-IDF OK as it remains build specific

Cons:

Pollutes the binary crate with stuff that should be .gitignore-d

Still does not follow the cargo policy that everything should be in the $OUT_DIR

Downloaded toolchains etc. cannot be re-used across builds of different binary crates

Option 4 - install and use an embuild-specific location within the OUT_DIR of the binary crate (i.e. $OUT_DIR/embuild/platformio and $OUT_DIR/embuild/espressif)

Pros:

Does not mess up with the user configuration

No global state

Patching ESP-IDF OK as it remains build specific

Does not pollute the binary crate with stuff that should be .gitignore-d

Does not follow the cargo policy that everything should be int he $OUT_DIR

cargo clean means everything is removed, including ESP-IDf patches. Really clean state

Cons:

cargo clean means everything will be re-downloaded again

Downloaded toolchains etc. cannot be re-used across builds of different binary crates

Preferences for a default?
Mines are:

Option 2

Option 3 (if global state is something you guys feel uneasy)

In any case, having a flag/switch/env var/whatever so that the build framework is operating in Option 1 mode is a prerequisite IMO.

Build script failure when building esp-idf-sys as dependency of previously working project

I have a project based on rust-esp32-std-demo that I've been successfully building for my ESP32 in the past, but today, when I said cargo build, it decided to recompile esp-idf-sys and the esp-idf-sys build failed, without me changing anything except for my own code. (I also get the same (similar?) error after switching to the latest esp-idf-sys version.)

I don't know how to tell if this is an esp-idf-sys issue, or an embuild issue, or something else, so I'm reporting it in both places; feel free to close this if it's in the wrong place.

I'm on Debian, and I installed esp-rs using rust-build as of Jan 11 (rust-build commit 6b71e690c35778c7c62ba5a229542cdfae01d6c4).

GPIO pins receive current during deep sleep

Running the code below keeps the led on during the deep sleep, which is different from what I've experienced using the Arduino libs.
Afaik unless gpio_hold_en(gpio_num_t gpio_num) is called alongside gpio_deep_sleep_hold_en(), the pin should go back to low during deep sleep.

I realise the latest commit is supposed to fix it, however I cannot build the latest. As a work around I have edited 'src/include/esp-idf/bindings.h' of commit "090311018dbbb0edc2efc8578c089edf4d59b10d", and modified line 65 to say '#include "driver/dac_common.h"' instead of the following as a hacky workaround.

esp-idf-sys/src/include/esp-idf/bindings.h

Line 65 in 9b49ade

#include "driver/dac.h"

From then on I am able to build and flash the project to my ESP32-S3 Dev Board successfully.

Compilation issue regarding MBEDTLS

It seems that this commit broke the template.

I think it's supposed to be added into the components list, but I don't know enough of how it's built to be sure.

Workaround:
Commenting out the offending lines fixes it.

Use tags to mark crate release versions

Is it possible/reasonable to tag versions of the esp-idf-sys crate that are released to crates.io? I'm hoping to see at a glance what the source is for different crate versions. Tags seem like a natural approach for this.

Support using ESP-IDF from the IDF_PATH variable

If the user has defined an IDF_PATH environment variable, the native build should use the ESP-IDF framework designated by that environment variable, rather than cloning and using a separate ESP-IDF GIT repo.

More details:

(Relevant for ESP-IDF versions 4.3.X which do require patching): This ESP-IDF instance should be considered "unmanaged" and should not be patched. It would be assumed, that the user has done that, possibly by providing an ESP-IDF fork which has all the Rust patches applied
Related to #36 : in addition to having IDF_PATH defined, the user may or may not have the tooling of that particular ESP-IDF instance install.sh-ed and export.sh-ed:
- If the tooling is already installed and exported by the user (can be detected by e.g. checking if idf.py is on $PATH), the native builder should not install any additional tooling, setup Python virtual env and so on. It should assume, that the necessary tooling is already on the path (scope of #36 actually, which turns out to be a sub-task of this one)
- If the tooling is not found on the $PATH, the installer should try to install it, based on the ESP-IDF instance pointed to by the IDF_PATH variable, and then proceed with setting up a virtual Python environment specifically for the build and so on.

404 not found for the doc URL

When open the doc URL from a web browser:

https://esp-rs.github.io/esp-idf-sys/

it will be redirected to this URL:

https://esp-rs.github.io/esp-idf-sys/build_wheel

However, the URL does not exist so GitHub Pages will return 404 file not found error.

It seems the correct URL will be:

Thanks!

External components discussion

Getting esp-idf-sys to build external components is relatively simple, I have PoC locally building esp-rainmaker. The hard part is how we tell esp-idf-sys where these external components are and what includes we need. Essentially the inter-crate communication.

It seems there is no way (unless I'm missing something, and I hope I am because it would make this really easy) in cargo to set environment variables for dependent crates; therefore a separate crate that depends on esp-idf-sys is out of the question because we can't give esp-idf-sys the information it needs to build these external components.

Option 1 - env variables in the final application

We already set custom variables to dictate the build, added something like ESP_IDF_EXTRA_COMPONENT_PATHS could work. The downside to this is that its yet another thing a user has to remember to include, and if its the case we have a separate wrapper crate for some external components we will get weird missing item errors when we try and build that crate if we forget to add our extra component variable

Option 2 - `esp-idf-sys` becomes monolithic

Instead of being able to customize the build process, the way to add new components would be to add them at the source level in esp-idf-sys. esp-idf-sys will then take care of downloading the external component and adding it into its normal build process. To save build time, it might be a good idea to put these external components behind feature flags.

There may be better options I haven't considered, I won't lie I'm not an expert in esp-idf-sys's build system hence why I am opening this 😅.

Cannot find bluedroid functions

I've created a project with esp-idf-template, added

CONFIG_BT_ENABLED=y
CONFIG_BT_BLUEDROID_ENABLED=y

to sdkconfig.defaults and stared to follow official esp-idf tutorial.

Unfortunately after implementing part of some of the functions were missing. Currently I see 3 of them: esp_bluedroid_init, esp_bluedroid_enable and esp_ble_gatts_register_callback. But when I searched generated bindings.rs file for "bluedroid" it found nothing despite some mentions in the comments.

I searched for the c header files in the embuild folder. I don't remember exactly were I found them, but every file I looked at was exactly the same as those in the esp-idf repository and contained all the functions that bindings.rs was missing.

Here is the function I was writing:

unsafe fn unsafe_init() {

No binding for efuse?

Hi, I was just looking around for a binding for the efuse manager api that I can find in esp_idf.

How come this is not added currently?

Compile only needed esp-idf components

Currently, when compiling the esp-idf all components are compiled by cmake, but only for select components the bindings are generated (everything that is included in src/include/esp-idf/bindings.h). That is currently around 1k C-files, which @igrr estimated could be brought down to around 600.
This behavior is not that detrimental as recompiling the esp-idf is normally rare (e.g. on first build, after clean). (There is also currently a bug where changing the sdkconfig/sdkconfig.defaults does not cause an esp-idf recompilation.)
However, when frequently changing the sdkconfigs or switing MCU, etc. and especially for CI such an improvement would be nice indeed.

To fix this we need to pass a list of components to cmake so that it knows specifically which components to build. As a first approach, we can disable building all components for which no bindings are generated (I don't how many that is, though).

In the long term though, we should make this configurable (maybe with an approach like I suggested in #72) as the demand for more and more esp-idf components grows.

Building in workspace, the .embuild folder is placed outside of the workspace dir

i'm trying to set up a Cargo workspace to build both Xtensa and RISC-V binaries for the ESP32-S2.

the setup is:

Workspace located at /opt/esp32-workspace
Binary crates at /opt/esp32-workspace/main and /opt/esp32-workspace/ulp

when I build from /opt/esp32-workspace, the embuild folder is created at /opt/.embuild, e.g. outside of the workspace.

for example building from:

/opt/esp32-workspace
/opt/.embuild is created

but when building from:

/opt/esp32-workspace/main (or any subdir)
/opt/esp32-workspace/.embuild is created

note also that this only happens when ESP_IDF_TOOLS_INSTALL_DIR is set to workspace or custom:./.embuild. the issue is fixed by using out, or an absolute path.

apologies if this is the wrong place to post this bug report!

deep_sleep timing

Hi,
when calling

esp_idf_sys::esp_sleep_enable_timer_wakeup(1_000_000u64);
esp_idf_sys::esp_deep_sleep_start();

the system goes to sleep but wakes up after approximately 5 seconds. I would have expected 1 second. The same holds for directly calling esp_idf_sys::esp_deep_sleep(1_000_000u64); . Is there anything else I have to configure?

Cargo-first build story with "pure" ESP-IDF tooling

I was looking at what it would take to replace (or have it as an additional option) the existing PlatformIO-based cargo-first build with a "native" esp-idf-tooling based cargo-first build.

Scope & Requirements

This is for now only for "Cargo-first" builds. I.e.:

The target audience consists of folks who would like to stay in "pure Rust" land
Use only Rust crates (the ones we provide here + commonly available)
Use Cargo as the one and only build tool (that's on the surface of course, but that's what they see and care about)
The firmware should be built as a standard Rust binary crate (with a main() function et. all) and not as a static library which is a better option for CMake/PlatformIO-first builds which are out of scope here
If - during the building of this esp-idf-sys crate (which is somehow the representation of ESP-IDF in Rust-land) - Cargo is invoking or even downloading other tools, like the Espressif toolchains, or CMake or Python - this is completely hidden from the user (unless the user wants to opt-in with their own ESP IDF SDK dir and/or .espressif toolchain dir).
The compilation of the ESP-IDF SDK itself is also completely transparent
No PATH alterations required before invoking Cargo
No special environment variables required (e.g. ESP-IDF) before invoking Cargo
Minimum prerequisites that the user has to install up-front (ideally, only Python3)

This story is currently implemented by utilizing the PlatformIO build capabilities.

Why ESP-IDF native toolchain?

Possibility to build and use the ESP-IDF master branch (PlatformIO only supports the last stable one)
Possibility to build and use older ESP-IDF releases (PlatformIO seems to support building e.g. ESP-IDF V4.2, but not sure for earlier ones - might require older versions of PlatformIO itself, whichis too big of a hack)
Create an "ESP8266" story with the "ESP-IDF-like" ESP8266 SDK. Maybe even with libstd support. Not supported by PlatformIO.
Faster build times (hopefully)

Assessment

The install.sh script available in the root of the ESP-IDF repository might be a very good start, fulfilling most (but maybe not all) of the above requirements:
(+) A thin wrapper over Python-based tooling in tools/
(+) Creates Python virtual envs and does not pollute the user's main Python environment (right?)
(+) Downloads all toolchains automatically
(+) Older and newer ESP-IDFs can co-exist (have separate python virtual envs)
(?) Can I use it on Windows without the "Windows installer" stuff?
(-) Some tooling besides Python still required on the PC of the user (cmake, ninja). PIO downloads this stuff too
(-) Grabbing the PATH requires running . ./export.sh. Can I do this with pure Python scripts?
(-) PowerShell necessary on Windows. Can I do everything with only Python scripts?

Harder stuff

How the esp-idf-sys works is that it essentially builds a hidden ESP-IDF "mini" project, which only contains a stubbed app_main function.

It then grabs all the artefacts of this build, namely:

(a) All ESP-IDF include directories -> needed for Bindgen so that we get unsafe bindings to various ESP-IDF APIs which are not mapped in Rust libstd and which are used by type-safe crates like esp-idf-hal and esp-idf-svc
(b) All ESP-IDF link artefacts: static libraries + linker scripts + linker flags and passes them up to the user's top-level binary crate, which is passing these to the Rust linker (which is whatever the rust target triple says - for our case - the linker from the relevant Espressif toolchain), together with the Rust libraries generated by pure Rust crates

So the question is: is there an easy way to "interrogate" the CMake build system, so that I can get (a) and (b)? With PlatformIO, I'm making use of Scons Construction Variables which provide all of this.

I'm sure there's a way to do this with CMake (or idf.py) too, I just don't know it yet. Any hints?

If we can solve (a) and (b), the rest is a breeze.

thread::yield_now() does not yield

This causes WDT timeout on ESP32.

thread::Builder::new()
    .name("yield".to_string())
    .spawn(move || loop { 
        std::thread::yield_now();

        // also does not work
        // unsafe { esp_idf_sys::vTaskDelay(0) };

        // but this works
        // unsafe { esp_idf_sys::vTaskDelay(1) };
    })
    .unwrap();

It is somewhat related to #66

Error when building on Linux aarch64

Then:

$ pio platform install espressif32
Platform Manager: espressif32 @ 3.3.2 is already installed

The rest of the packages will be installed later depending on your build environment.

So I successfully hacked my way by manually modifying platforms/espressif32/platform.py to require toolchain-xtensa32 @ 2.50200.97 instead of toolchain-xtensa32 @ 2.80400.0

But then I got the following error:

Tracking issue to use native build strategy as default

This issue tries to list everything that has to be done for us to switch to the native esp-idf build strategy.

#11
- Currently native uses <workspace-dir>/.espressif and pio uses the platformio default.
#12
- Cannot be done using idf_tools.py as that version is outdated
- Need at least version 3.20 with cmake-file-api toolchains object or 3.14 without.
Decide whether python3 should remain a user requirement (#18)
Decide whether we should switch away from idf_tools.py and roll our own install logic. (see #10 (comment))
- It would give us more freedom.
- Removes dependency on idf_tools.py.
- We need some install logic for cmake anyway.
- idf_tools.py requires workaround for windows when using msys or git-bash.

It seems that the docs.rs build environment does not have a networking stack available, so the platformio installation script fails. Is there any way to provide fallback information in the build.rs script so that the docs can be built without networking?

Failure to build with the Espressif-built compiler

I’m trying to build rust-esp32-std-hello using the pre-compiled compiler I installed according to this guide. (I have previously built the compiler myself, but I wanted to cut the installation time by a couple of hours this time.)

I’m using rustup to manage toolchains. Having set the local override to esp, I’m getting this output:

$ rustc --version
rustc 1.53.0-dev
$ rustc --print target-list | grep xtensa
xtensa-esp32-espidf
xtensa-esp32-none-elf
xtensa-esp32s2-espidf
xtensa-esp32s2-none-elf
xtensa-esp8266-none-elf
xtensa-none-elf

However, during the build, I’m getting this error:

$ cargo build
   Compiling esp-idf-sys v0.16.3
error: failed to run custom build command for `esp-idf-sys v0.16.3`

Caused by:

Install cmake from the native build script

Currently a user requirement, but inconvenient. In addition pio doesn't have this requirement.

Native build does not work with ESP-IDF branches named `release/vX.X`

Generate a Cargo ESP-IDF project using the esp-idf-template:

cargo generate --vcs none --git https://github.com/ivmarkov/esp-idf-template cargo

When asked to select ESP-IDF native build version (stable = 4.3, upcoming = 4.4, master = 5.0; applicable only with cargo build --features native), choose upcoming
Enter the generated project:

cd <your-project>

Build:

cargo build --features native

ESP_ERR* constants should be `i32`

Errors are defined as:

typedef int32_t esp_err_t;

/* Definitions for error constants. */
#define ESP_OK          0       /*!< esp_err_t value indicating success (no error) */
#define ESP_FAIL        -1      /*!< Generic esp_err_t code indicating failure */

#define ESP_ERR_NO_MEM              0x101   /*!< Out of memory */
#define ESP_ERR_INVALID_ARG         0x102   /*!< Invalid argument */
#define ESP_ERR_INVALID_STATE       0x103   /*!< Invalid state */
#define ESP_ERR_INVALID_SIZE        0x104   /*!< Invalid size */
#define ESP_ERR_NOT_FOUND           0x105   /*!< Requested resource not found */
#define ESP_ERR_NOT_SUPPORTED       0x106   /*!< Operation or feature not supported */
#define ESP_ERR_TIMEOUT             0x107   /*!< Operation timed out */
#define ESP_ERR_INVALID_RESPONSE    0x108   /*!< Received response was invalid */
#define ESP_ERR_INVALID_CRC         0x109   /*!< CRC or checksum was invalid */
#define ESP_ERR_INVALID_VERSION     0x10A   /*!< Version was invalid */
#define ESP_ERR_INVALID_MAC         0x10B   /*!< MAC address was invalid */

#define ESP_ERR_WIFI_BASE           0x3000  /*!< Starting number of WiFi error codes */
#define ESP_ERR_MESH_BASE           0x4000  /*!< Starting number of MESH error codes */
#define ESP_ERR_FLASH_BASE          0x6000  /*!< Starting number of flash error codes */

However in rust they are:

pub type esp_err_t = c_types::c_int;

pub const ESP_OK: u32 = 0;
pub const ESP_FAIL: i32 = -1;

pub const ESP_ERR_NO_MEM: u32 = 257;
pub const ESP_ERR_INVALID_ARG: u32 = 258;
pub const ESP_ERR_INVALID_STATE: u32 = 259;
pub const ESP_ERR_INVALID_SIZE: u32 = 260;
pub const ESP_ERR_NOT_FOUND: u32 = 261;
pub const ESP_ERR_NOT_SUPPORTED: u32 = 262;
pub const ESP_ERR_TIMEOUT: u32 = 263;
pub const ESP_ERR_INVALID_RESPONSE: u32 = 264;
pub const ESP_ERR_INVALID_CRC: u32 = 265;
pub const ESP_ERR_INVALID_VERSION: u32 = 266;
pub const ESP_ERR_INVALID_MAC: u32 = 267;

pub const ESP_ERR_WIFI_BASE: u32 = 12288;
pub const ESP_ERR_MESH_BASE: u32 = 16384;
pub const ESP_ERR_FLASH_BASE: u32 = 24576;
pub const ESP_ERR_HW_CRYPTO_BASE: u32 = 49152;

Notice that esp_err_t is i32 and ESP_FAIL is i32 but all other constants are u32.

This makes error handling a bit tricky. This would not work because of type mismatch:

match unsafe { twai_transmit(&frame.0, portMAX_DELAY) } {
    ESP_OK => Ok(None),
    ESP_FAIL => Err(nb::Error::WouldBlock),
    ESP_ERR_TIMEOUT => Err(nb::Error::WouldBlock),
    _ => Err(nb::Error::Other(embedded_hal::can::ErrorKind::Other)),
}

For me it seems all those constants must be defined as i32, this is what esp_err_t expects them to be. I checked https://github.com/esp-rs/esp-idf-sys/blob/master/src/error.rs#L10 but it seems I still do not have a good way to match particular error using a constant.
I could do this, but this seems so wrong:

const _ESP_OK: i32 = ESP_OK as i32;
const _ESP_ERR_TIMEOUT: i32 = ESP_ERR_TIMEOUT as i32;

match unsafe { twai_transmit(&frame.0, portMAX_DELAY) } {
    _ESP_OK => Ok(None),
    ESP_FAIL => Err(nb::Error::WouldBlock),
    _ESP_ERR_TIMEOUT => Err(nb::Error::WouldBlock),
    _ => Err(nb::Error::Other(embedded_hal::can::ErrorKind::Other)),
}

How to set flash size

I'm currently trying to change the flash size from 2 MB to 8 MB as I am getting the following warning:

W (269) spi_flash: Detected size(8192k) larger than the size in the binary image header(2048k). Using the size in the binary image header.

However I am unsure how to do this properly. Changing the flash size in the sdkconfig does not work either.

Document all the environment variables that configure the PIO & Native builds

Some of these are available here, with some comments, but the list is not exhaustive. We need to document these in the README.md page of esp-idf-sys.

Slow rebuilds with `native` feature

I think there was another issue floating around about slow builds, but I can't seem to find it now.

It seems making any change to the build when using the native feature forces an entire rebuild (possible recloning too?). Perhaps the file tracking for rebuilds on native build is tracking something it shouldn't.

This errors with all versions of esp-idf-sys, the latest and the oldest I could find that satisfied the API I need.
I am building without the native feature.

Undeclared defines while building native (DR_REG_EMAC_BASE)

I try to build the crate for the esp32c3 with native feature #10 enabled and get the following error:

FAILED: esp-idf/esp_eth/CMakeFiles/__idf_esp_eth.dir/src/esp_eth_mac_openeth.c.obj
In file included from /root/.espressif/esp-idf-release/v4.4/components/esp_eth/src/esp_eth_mac_openeth.c:36:

   #define OPENETH_BASE                DR_REG_EMAC_BASE
...

I use the version release/v4.4 and have CONFIG_ETH_USE_OPENETH=y enabled.

It could be a wrong configuration, so I tried to use the cargo-idf tool. But it depends on the same build, so it fails with the same error.

I recognized the macro is defined in soc/esp32/../reg_base.h. But this header is not be included when building for the esp32c3 in my configuration.

Hey there! While building the library I stumbled upon an error:

I am building this library via the pio feature and also have the binstart feature enabled. This log is from building the newest version (v0.24.1) but I experienced the error with every previous version I tried as well.

Cannot compile `esp-idf-sys` when parent project has no commits

Creating a new cargo project and then including esp-idf-sys without creating an initial commit in the project causes esp-idf-sys not to compile.

Removing git from the project or adding an initial commit lets the project compile fine. Running the build in verbose mode (cargo build -vvv) returns the following:

Generate Rust bindings for MQTT ESP-IDF APIs

Hi, esp-rs team,
I'm implementing a project with ESP32C3 RUST, and I will apply the MQTTs APIs of native ESP-IDF. I check the code, it seems not support yet. I'm not sure if im right?
If yes, could you give me some advice how to implement MQTTs with esp-idf-sys?
Or there's no choice but to move back to C currently?

ESP_IDF_SDKCONFIG_DEFAULTS & ESP_IDF_SDKCONFIG should have default values, so to say

Forcing the user to specify one of these two is maybe a bit too much? It is OK that we have these, but if these are not specified, I think esp-idf-sys should still look into the workspace root and fetch (& use) files which match the patterns:

sdkconfig.*
sdkconfig.defaults.*

LoadProhibited exception when using `EspMutex`

The implementation for EspMutex was recently changed from using a pthread_mutex_t to a *mut pthread_mutex_t. This is incorrect as when locking, the pthread_mutex_lock function calls pthread_mutex_init_if_static which dereferences the mutex pointer. Because this pointer is initially set to PTHREAD_MUTEX_INITIALIZER (0xFFFFFFFF), this causes a load to this address which is invalid and causes a LoadProhibited exception.

Unable to create a working environment.

This might link to esp-rs/rust-build#8, as I haven't installed ESP-IDF yet.
But I'm unable to compile libsodium.

Can't compile

Can't compile. Don't know what to do with these errors. Let me know if you need any more info.

Error compiling - PlatformIO

Hello

I am attempting to make my own ESP32 Rust project, however when I try to compile it using cargo build I get the following error:

Caused by:
  process didn't exit successfully: `/home/carl/Documents/git/github/davidcarl/ESP32-Build/target/debug/build/esp-idf-sys-b9e81c780502d3bf/build-script-build` (exit status: 101)
  --- stdout
  cargo:rerun-if-env-changed=ESP_IDF_TOOLS_INSTALL_DIR
  cargo:rerun-if-env-changed=ESP_IDF_SDKCONFIG
  cargo:rerun-if-env-changed=ESP_IDF_SDKCONFIG_DEFAULTS
  cargo:rerun-if-env-changed=MCU
  Found compatible PlatformIO Core 5.2.5 -> /home/carl/Documents/git/github/davidcarl/ESP32-Build/.embuild/platformio/penv/bin/platformio

I am able to build the rust-esp32-std-demo project, and I have attempted to gut this project for all the necessary dependencies, however I run into this error now.

I have attempted to reinstall my toolchain (multipletimes), cargo clean and cargo update however it still just keep not working.

Thanks in advanced

ESP-NOW support

Hi!

I was wondering if there are any plans to support ESP-NOW which is part of ESP-IDF too.

I've built a couple of projects on it (on top of Arduino stack) and was very happy with the possibilities of having a p2p broadcast network that did not require an intermediate wifi router while having quite efficient communication between ESP devices.

Support for starting build in activated ESP-IDF environment

Use case: User deploys ESP-IDF starts the environment using export.[sh|bat|.ps1]. The script adds path to tools to PATH and configures some additional environment variables. User switches to the directory with Rust project and enters: cargo build.

Observed behavior: The build fails, because embuild attempts to clone new ESP-IDF and activates new virtual environment inside existing virtual environment which fails.

Desired behavior: The build is able to determine that it's running inside activated ESP-IDF with all variables and tools set, so it's not necessary to perform installation procedure and invokes the build with tools available on PATH.

undefined reference to `app_main' with native build

esp-test-error-fixed.zip. I added

#[export_name = "app_main"]
extern "C" fn dummy() {}

to get it working.

I have the latest ldproxy (ldproxy-0.2.0).

Seems like the dummy cmake project isn't being includedin the native build?

External component

Hey, guys! Thanks for building such a great library! I just have a quick question - is there a way to use external (custom) ESP-IDF component in building this crate? Like importing with some env variable or anything else? For a moment I see that all of framework components and their headers are hardcoded in binding.h for bindgen and without modification of sources I won't be able to integrate smth. Thanks in advance!
