IRQ and xTaskResumeFromISR

Posted by Nobody/Anonymous on August 21, 2006
I'm using ARM7 based board without Interrupt Controller like on LPCxxx.
I have only one task suspends yourself:

task1( void *pvParameters ){
int i;
for (;;){

I have declaration of IRQ handler (not ISR task) like below:

_interruptHandler() __attribute__ ((naked))
if( IRQ1 ){
if(xYieldReq== pdTRUE)

I've tried use portEXIT_SWITCHING_ISR but these macrosses are only for ISR's task.

How exactli can I perform resumming within IRQ hendler?

Should this not be:

_interruptHandler() __attribute__ ((naked))
int xYieldReq = 0;
if( IRQ1 ){

xYieldReq is a parameter to portEXIT_SWITCHING_ISR.

Alternatively just save the context of the task on entry to the IRQ using portSAVE_CONTEXT and restore it on exit using portRESTORE_CONTEXT, then call vTaskSwitchContext as you were.
