FreeRTOS问题汇总

Error[2]: Failed to open #include file 'FreeRTOSConfig.h' E:\Project\arm\STM32\F7_HAL_FreeRTOS\FreeRTOS\portable\IAR\ARM_CM7\r0p1\portasm.s 28 

解决办法：工程名右键->Options...->Assembler->Preprocesser在Additional include directories添加FreeRTOSConfig.h所在目录。

解决方法：由于PendSV_Handler，SVC_Handler，SysTick_Handler三个中断函数重定义，可以注释掉stm32xxxx_it.c中这三个函数。

port.c中vPortSVCHandler，xPortPendSVHandler ，xPortSysTickHandler在FreeRTOSConfig.h通过下面三个宏定义成上面那三个函数。

#define vPortSVCHandler SVC_Handler
#define xPortPendSVHandler PendSV_Handler
#define xPortSysTickHandler SysTick_Handler
