Compiler/EVMK2H: OSAL Nonos Usage

Tool/software: TI C/C++ Compiler

Hey All,

So I ran into a curious problem today, I got timer interrupt, and a GPIO interrupt running using the OSAL working independently. I tried to merge the two together to have the timer interrupt trigger a GPIO interrupt but it seems that only the timer interrupt is triggered. The timer ISR calls the OSAL to toggle and LED but never triggers the GPIO. I tried stepping through the code but it seems to never run back to main. Does any one have any thoughts on this?

Hi Alfredo,

I've notified the RTOS team. They will post their feedback directly here.

Best Regards,

Is this on the DSP or ARM? Can you please clarify how the timer interrupt is meant to interrupt the GPIO interrupt? Is the GPIO input or output. Can you please share the code which you have used to merge the timer and GPIO interrupt. This is hard to comment on without any understanding of your interrupt hook up or OSAL usage.

Rahul
