vPortYieldProcessor impelemntationPosted by Hossam Alzomor on April 8, 2010 Hi 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? Salam Hossam Alzomor RE: vPortYieldProcessor impelemntationPosted by Hossam Alzomor on April 8, 2010 in portisr.c /* ISR to handle manual context switches (from a call to taskYIELD()). */ void vPortYieldProcessor( void ) __attribute__((interrupt("SWI"), naked)); and in boot.s @ address 0x00000008 ldr pc, _swi/* SWI - _swi*/ and _swi: .word vPortYieldProcessor /* SWI*/ RE: vPortYieldProcessor impelemntationPosted by Hossam Alzomor on April 8, 2010 I am sorry It seams that the interrupt vector is not copied correctly
