CC1354P10: Program crashes into faultISR - need help debugging

Sebastian K

Part Number: CC1354P10

Hi,

I have a CC1354 running FreeRTOS and my program occasionally crashes into faultISR. I'm not sure what's causing it and would appreciate any help.

The call stack only shows faultISR with no further context, so I'm having trouble tracing back to the original cause.

Any tips on how to further debug this?

Thanks

Hi Sebastian,

Do the core registers indicate anything ? Such as PC, MSP, or R0.. This is the ones I mean: View online

Solved. The issue was an uninitialized QueueSet handle. FreeRTOS was trying to write to a garbage address from the uninitialized variable, which caused a BusFault escalated to HardFault.

Tried analyzing registers (HFSR, CFSR, BFAR, stack frame) but it didn't lead anywhere useful. In the end, stepping through the code line by line landed me inside FreeRTOS QueueSet functions where I spotted the uninitialized handle.
