[esp32-c3][rt-thread] run RT-Thread BSP minimum system based on esp32c3

brief introduction

Recently, I found a development board with super high cost performance 9.9, Tried it on , I can't believe it debug, There's no need for JLINK Wait for the debugger .
Moreover, the ecology of Lexin's chip is very open source , So and RT-THREAD Can we try the open source ecosystem of ？
If you can , Is it right? RT-THREAD The cheapest , The most cost-effective hardware platform ？ It can be debugged , You can also run RT-THREAD.
But I really can't find a cheaper development board , Do you have any cheaper ones to run RT-THREAD Recommended by . Less than 9.9 Of , Most of the materials are open source .
There are two types of this development board , Classic models can't debug Debugging , Simple style can debug Debugging

How to run

See for warehouse code and description https://github.com/RT-Thread/rt-thread/tree/master/bsp/ESP32_C3
This bsp Almost support ESP32-C3 Most of the development boards .

Set up the environment

It is suggested to use vscode worry .

Everyone knows Le Xin's IDF The environment is extremely difficult to install , Many of my friends are trying to persuade me to quit on the way of installing environment .
Many methods have been tried here , Finally, use one of the simplest methods , use vscode
How to install , Refer to previous articles ESP-IDF The one click build environment is based on VSCODE It's simple , As long as you use window Or other ubuntu And other graphical interfaces , You can run vscode, You can use this method ,（ Of course, you can also use the official setup Tool installation ,idf Environment compilation is also possible ）

IDF patch load

Due to the official IDF It uses freertos, If you want to run RT-THREAD, The kernel needs to be replaced , This way bsp Here's a patch, Just find it before esp-idf Of the code Click the following command in the installation directory

cd esp/esp-idf
git checkout v4.4
git am 0001-add-the-config-of-RTTHREAD.patch

because idf Update too fast , And too many versions , At present, it can only be compatible with v4.4 edition , Continue to maintain later

compile

stay bsp/ESP32_C3 Right click in the directory to open vscode, If the environment is installed , You will see the following picture

Compile and select the bottom button ：

download

good , The most important step is coming , here , If you are connected to a serial port , Directly in accordance with the readme Just the introduction inside ,
If you just bought the minimalist version , The congratulations , Your development board can be used to debug debugging

debug debugging

Just follow the following figure

Okay , It's almost finished here , After burning , You can see the small light flashing , Serial port has log Print

summary

Now this bsp Not perfect yet , It can support nano Version of RT-THREAD, Only the kernel is running , It still needs to be improved in the future , Let's try some fresh food first . Welcome to play the cheapest game in history RT-THREAD Hardware development board . Due to limited time , Welcome to PR.
