FreeRTOS问题汇总

Error[2]: Failed to open #include file 'FreeRTOSConfig.h' E:ProjectarmSTM32F7_HAL_FreeRTOSFreeRTOSportableIARARM_CM7r0p1portasm.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。

Error[Li006]: duplicate definitions for "PendSV_Handler"; in "E:ProjectarmSTM32F7_HAL_FreeRTOSEWARMF7_HAL_FreeRTOSObjportasm.o", and "E: 
Error[Li006]: duplicate definitions for "SVC_Handler"; in "E:ProjectarmSTM32F7_HAL_FreeRTOSEWARMF7_HAL_FreeRTOSObjportasm.o", and "E:Project 
Error[Li006]: duplicate definitions for "SysTick_Handler"; in "E:ProjectarmSTM32F7_HAL_FreeRTOSEWARMF7_HAL_FreeRTOSObjport.o", and "E:Project 

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
