Hi.
On 6437 EVM the following code not working properly.
/*
* ======== main ========
*/
Void main() {
LOG_printf(&trace,"Start of semaphore. \n");
return;
}
void uartTSK(void)
{
while(1)
{
SEM_pend(&sems,SYS_FOREVER);
LOG_printf(&trace, "TSK0 Start");
// TSK_yield();
LOG_printf(&trace, "TSK0 Main");
// TSK_yield();
LOG_printf(&trace, "TSK0 Finish");
// TSK_yield();
SEM_post(&sems);
}
}
/*
* ======== video_preview ========
*/
void video_preview(void)
{
while(1)
{
SEM_pend(&sems,SYS_FOREVER);
LOG_printf(&trace, "TSK1 Start");
// TSK_yield();
LOG_printf(&trace, "TSK1 Main");
// TSK_yield();
LOG_printf(&trace, "TSK1 Finish");
LOG_printf(&trace,"Start of semaphore. \n");
// TSK_yield();
SEM_post(&sems);
}
}
sems is set to 1.
video_preview task priority 4.
uartTSK task priority 3.
The output of trace is .
30766089 TSK1 Start 30766090 TSK1 Main 30766091 TSK1 Finish 30766092 Start of semaphore. 30766093 TSK1 Start 30766094 TSK1 Main 30766095 TSK1 Finish 30766096 Start of semaphore. 30766097 TSK1 Start 30766098 TSK1 Main 30766099 TSK1 Finish 30766100 Start of semaphore. 30766101 TSK1 Start 30766102 TSK1 Main 30766103 TSK1 Finish 30766104 Start of semaphore. And so on ....
It looks like the SEM_post(&sems); is not working .
Please Advise.
