https://devzone.nordicsemi.com/f/nordic-q-a/50564/gdb-backtrace-in-sdk-15When I hit the app_error_fault_handler() , gdb doesn&#39;t have a stack trace anymore: Backtrace stopped: previous frame identical to this frame (corrupt stack?) There used to be this config HARDFAULT_HANDLER_GDB_PSP_BACKTRACE but it&#39;s gone in SDK 15.

You can use the SDK release notes to see the toolchains versions we have used for test and verification.&nbsp;</p> <p>What is the fault &quot;id&quot; passed to the error handler? Note that you will not get a backtrace if it is a Softdevice assert&nbsp;(NRF_FAULT_ID_APP_MEMACC/NRF_FAULT_ID_SD_ASSERT)</p><div style="clear:both;"></div>
