ChibiOS Free Embedded RTOS

Thanks Giovanni.I will do as you mentioned.

@mobyfab, Thanks. I am still using V2.6.1 but the driver you pointed out is for V3.0
Shall I shift to V3.0?

Dear Giovanni,

I need to use four input capture module for Timer2, the hardware is developed like that.
Currently chibios input capture interrupts support 2 channels for a timer but I have to use four.
So I used STM32 standard library interrupts for input capture alone.
Now I get hardfault error ...

All the ISR are defined by me.Im not using any os functions there.Im using STM standard library functions for interrupt generation.

Im using ST link debugger.It doesnt have traceability option.

One thing I found is if any exception happens from any ISR, everything freezes.Is there any way to enable the interrupts after an exception happens? For me it is happpening from ISR not from thread.

Actually Im getting SV#10 not SV#4
Is there any document explaining how to trace stack?

int main(void) {
Initialize_OS(); //Initialze ChibiOS related functions
Initialize_Threads(); //Initializing thread

while (1) {

}
}

void Initialize_Threads(void) {

static WORKING_AREA(Task1, 2624);
Thread_Id = chThdCreateStatic(Task1, sizeof(Task1), NORMALPRIO, Thread, NULL);
}

msg_t ...

It was there.But I commented everything.Still the same result.

int main()
{
static WORKING_AREA(Task1, 2624);

Thread_Id = chThdCreateStatic(Task1, sizeof(Task1), NORMALPRIO, Thread, NULL);
while(1);
}

msg_t Thread(void *arg)
{
while (TRUE) {
chThdYield();
}
}

This piece of code is giving error as misplaced I-class function.
What could be the reason?

hi,

Thanks for your reply.I enabled all debug options and I'm getting SV#4, misplaced chSysLock().I didnt find an answer why this error is happening because im using only chThdYield() function call in four threads.Im not using chSysLock() anywhere in my application.

hi,

I have a doubt regarding unhandled exception.My code works perfectly for around 13 hours.After that unhandled exception is triggered.As a fix for this I disable the unhandled exception.If exception comes code goes to nvicEnableVector() function in nvic.c and all my code gets freezed.How can i ...
