@leopck Thank you. That helped a lot! Remember that esp-open-sdk already takes care of downloading the sdk. That makes your wget redundant.
For anyone reading this who doesn't feel like bloating your system with all these dependencies. I created an executable docker image that can easily compile and flash your stuff. https://github.com/T-vK/docker-esp-sdk
It is very well documented and super easy to use. :)
You can also just refer to my Dockerfile if you want to know all steps necessary to get the build environment running. https://github.com/T-vK/docker-esp-sdk/blob/master/Dockerfile

Hmm... It does already map as a keyboard + mouse. You would have to modify it to say it only has one interface and select just the keyboard interface to make it keyboard only. To really "get" user/usb_config.h you'll have to read up a good bit about USB descriptors.
The IP parameter sets the parameter for where the netburn system expects the ESP8266. You use the web-based configuration to set the ESP's network information, i.e. if it is a softap or if it is connected to an infrastructure.

Oh, I didn't realize that it would map as keyboard+mouse by default. I thought this was just a general USB library. It might be a good idea to put that information into the readme file.
And about netburn: How do I make my esp8266 work with that? It's currently running nodemcu, I don't think it understands netburn. Do I have to do a netburn or can I just do a burn to a serial port?

Netburn only works with esp82xx projects, once you serial-burn the firmware once, you can netburn every time thereafter.

I have tried to get it to work for over a week now and I'm starting to think that you use an old version of the sdk or something?
I successfully got the toolchain to work within a docker image: https://github.com/T-vK/docker-esp-open-sdk/blob/master/Dockerfile But that's only a build environment, I have no idea how I would pass a serial port through to the image.
So I tried to install the toolchain in a VM following this guide: https://github.com/esp8266/esp8266-wiki/wiki/Toolchain But sadly the guide is outdated and wasted hours of my time.
So I digged up the official documentation that espressif provides and found that they provide a VM image that has the toolchain preinstaled (http://bbs.espressif.com/download/file.php?id=1450). I just had to add the SDK to ~/Share/ESP8266_NONOS_SDK.
Now here is what I did:
git clone https://github.com/cnlohr/espusb.git
cd espusb
git submodule update --init --recursive
# adjusted these values in the user.cfg
# SDK_DEFAULT = $(HOME)/Share/ESP8266_NONOS_SDK
# ESP_GCC_VERS = 4.8.2
make burn
The result of that last command:
fails esp82xx/common.mf:37: Warning: No shell variable 'ESP_ROOT', using '/home/esp8266/esp8266/esp-open-sdk'
Makefile:10: warning: overriding commands for target `usbburn'

make: *** [image.elf] Error 127
So I set the shell variable for the command by running env ESP_ROOT="~/Share/ESP8266_NONOS_SDK" make burn.
Result:
Makefile:10: warning: overriding commands for target `usbburn'
esp82xx/main.mf:113: warning: ignoring old commands for target `usbburn'

Okay, now that is really weird. Accoring to espressif the xtensa-lx106-elf should be in /opt. And sure enough it was preinstalled in /opt/xtensa-lx106-elf.
But I was curious and pasted a copy of that folder into my ESP8266_NONOS_SDK folder and ran the same command again. Result:
Makefile:10: warning: overriding commands for target `usbburn'
esp82xx/main.mf:113: warning: ignoring old commands for target `usbburn'

What is wrong here? There are so many issues. How hard can it be to get this to work?

Yes, looks like SDK version is too new. I think it must be 1.5.2 or older. See what version is currently in use in the ESP8266_NONOS_SDK, and make sure to download 1.5.2 or older.

@cnlohr SDK 1.5.4 works too. Haven't got the SDK 2.0 to work though. #5

commented on September 3, 2024
Yeah, I'm using 2.0... @cnlohr Any idea when you'll upgrade to 2.0?
A mention of the 1.5.2/1.5.4 requirement might be even more important than the how to use section in the readme.

@T-vK Hi you can refer to this issue on document about this:
#5
I added some notes below of my comment.
EDIT: Btw this tutorial is slightly outdated since it is a different GPIO pinout and espusb is now using esp82xx. I'll probably write out a tutorial on it after working on a few more things for espusb. But essentially you probably just need to change a few lines here and there and the GPIO pinouts only and it'll work.
