Tool/software: TI-RTOS

Hi all,

I'm using CCV8, with SYS/BIOS 6_70, XDC3_50_05_12

I updated my code, while testing the code in debug, the code enters into infinite loop.

it doesnt exits, unless i stop the debug.

I couldn't find what is causing it, since it goes to disassembly code and shows

xdc_runtime_Text_xprintf__I()

"could not read the  (the address), execution state is prevented access"

Most of the time when it happens, the code was using fwrite, to write to a file outside.

is there a way to trace back to find the bug in my code?

Hi Nancy,

What I'd do is add breakpoints in to my code and start executing it step by step, stepping into every function called in the code. This way you will see what in your code is causing the sysbios hang.

Hi,
The problem doesnt occur all the time, so the solution suggested wouldn't work in my case.

In this case, what code are you running? Which peripherals does your application use?

Could you explain in more details your use case?

What changes (if any) have you made to the Processor SDK RTOS code?

Best Regards,
Yordan

Hi Yordon,

I kind of figured it out, where the issue is , the code was calling the DSPLIB- DSPF_sp_minval(), with the input not within the limit, but wonder

why the DSPLIB, didn't exit the loop, instead it went in to infinite loop, and never exits unless i stop the debugger
