通过keil RTE, 移植freertos到GD32F103C8. 用最新的freertos V11 + compiler V6

其实这里不限GD, ST的, AT的都行. 因为很多例程都是基于V10版的freertos和arm compiler V5.
而我想用最新的freertos V11 + compiler V6, 所以只能自己新建和移植.
V6据说编译会快很多.

1. 首先安装 相应MCU的keil驱动, 器件库, 一般各大MCU的官网都有, 耐心找找.

注意最新版的keil, 器件库的安装目录不再在C盘的根目录, 而是在user/appdata里面, 安装错了, keil里面新建工程找不到厂家和器件.

2. 安装 freertos的ARM.CMSIS-FreeRTOS.11.2.0.pack
https://github.com/ARM-software/CMSIS-FreeRTOS/releases

3.新建工程, 选mcu厂家和型号

4.在keil里面点RTE, 配置启动文件, cms, 外设驱动lib, freertos等:

然后要新建一个main.c和gd32f10x_it.c, 加入到工程, 点编译看能否通过.
需要修改 FreeRTOSConfig.h
把MPU的选项注释

//  <i> Maximum priority of interrupts that are safe to call FreeRTOS API.
//  <i> Default: 128

//vTaskList and vTaskGetRunTimeStats APIs take a buffer as a parameter and assume
//that the length of the buffer is configSTATS BUFFER MAX LENGTH. Defaults to*.0xFFFF if left undefined.
//New applications are recommended to use vTaskListTasks and vTaskGetRunTimeStatistics A
//pIs instead and supply the length of the buffer, explicitly to avoid memory corruption.
