[FreeRTOS笔记1] STM32CubeMX FreeRtos错误

STM32CubeMX FreeRtos错误

在检查错误前一定要有FreeRTOSConfig.h文件

错误1

HAL库用AC6编译器

解决：在MDK目录里找到GCC\ARM_CM3替换掉RVDS\ARM_CM3

加路径：

用

…\Middlewares\Third_Party\FreeRTOS\Source\portable\GCC\ARM_CM3

换掉

…\Middlewares\Third_Party\FreeRTOS\Source\portable\RVDS\ARM_CM3

编译

解决：

去掉 mexecute -only
