I am currently working on porting FreeRTOS to AT91SAm7A1 processor. While navigating the code I found that vPortYieldProcessor is defined as SWI and in boot.s I found that the SWI handler is pointing to vPortYieldProcessor which makes an endless loop. Am I right or there something that I can't understand?
