Mcuxpresso 10.0.2, FreeRTOS and Segger Thread Aware Debugging

ypkdani — Tue, 01 Aug 2017 10:36:01 GMT

Hello i have a problem setting breakpoints with a firmware that use the Freertos. I have different thread so i want to use the Thread Aware Debugging.

I have this setting

but there is this error in red:

can you help me?

in FreeRTOSconfig.h i have set

Hi Daniel,

I suspect something is overwriting your RAM. It seems that your uxTopUsedPriority variable has the value 0x72 which is indeed too high and does not make any sense.

I recommend to increase the task stack size (see Troubleshooting Tips for FreeRTOS Thread Aware Debugging in Eclipse | MCU on Eclipse ), and if this does not help, set a watchpoint on uxTopUsedPriority (see C/C++ Watchpoints with Eclipse Kepler | MCU on Eclipse , same principle works with MCUXpresso IDE too).

I hope this helps,

Erich

Hello and thanks,

i have find the solution following this post BUG: KDS debug call-stack fails with Segger JLink

I have Create a dummy symbol uxTopUsedPriority (will be preferred to uxTopReadyPriority) and set it to configMAX_PRIORITIES.
