rtthread-esp-idf's Introduction

rtthread-esp-idf

RT-Thread针对ESP32的移植（使用Espressif Systems的IDF框架）

获得rtthread esp-idf

获得RT-Thread的ESP32版本，需要安装git，并以以下方式获得代码：

git clone https://github.com/BernardXiong/rtthread-esp-idf

cd rtthread-esp-idf
git submodule init
git submodule update

cd esp-idf-port/esp-idf
git submodule init
git submodule update

git apply ../esp-idf-port.patch

交叉编译工具链下载

注：交叉工具链目前验证过的是1.22.0-61版本，工具链版本太高，或太低都不行。

Linux版本：

CentOS 7::

sudo yum install git wget make ncurses-devel flex bison gperf python pyserial
Ubuntu and Debian::

sudo apt-get install git wget make libncurses-dev flex bison gperf python python-serial
Arch::

sudo pacman -S --needed gcc git make ncurses flex bison gperf python2-pyserial

依赖软件

scons
python
pyserial

安装Python后，可以安装pip，以pip install scons pyserial的方式安装其他

编译

修改根目录下"rtconfig.py"文件内EXEC_PATH = r'D:\tools\msys32\opt\xtensa-esp32-elf\bin'为xtensa-esp32-elf交叉编译器所在目录；
在命令行下使用scons命令编译并生成bin文件或直接执行make all；

rt-iot audio开发板烧录

rt-iot audio开发板因为有音频的缘故，未包括串口自动复位烧录的操作，所以在进行烧录时，需要以按键方式辅助。

USB连接PC和开发板；
在PC上运行烧写的软件，它会打开串口试图烧写；
按住rt-iot audio朝外边的两个按键，然后按最内侧按键（reset按键），松开内侧按键，然后再松开外侧两个按键。

这个时候PC侧软件自动进入烧写模式，开始进行固件烧写。

音频

当前在applications下放了两个音频相关的代码：

wav_play.c -- 用于播放一个wav文件；
wav_record.c -- 用于录音（默认以16000 samplerate、单声道方式录音，并保存为文件）

ubuntu14.04编译报错，Could not find platform independent libraries <prefix>.....

貌似是在最后一步，调用python脚本生成镜像的时候报错：

执行patch的时候出现这个问题，这个怎么处理啊
