HardFault when I use os_evt_wait_or

Ben Beliveau over 16 years ago

With STM32 (Cortex M3)...

when I execute this, the RTX jumps to HardFault_Handler in STM32F10x.s

if(os_evt_wait_or(flag1 | flag2 | flag3 | flag4, 15) == OS_R_EVT)
{ bla bla bla
}

I don't know what to do.

Hi,
can you post some more informations?
Where is it called, from a "normal" function or an ISR?
Do other RTX-functions fail too?

I have found my problem. One of my tasks had no inifite loop. Strange but that was the cause of my problem.

Thanks.

Thats one of the main problems when I started writing apps with RTX:
The root cause of a problem is often not there, where the problem itself appears.
