GDB backtrace in SDK 15

bart

When I hit the app_error_fault_handler(), gdb doesn'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's gone in SDK 15. Is this now enabled by default, or has it been removed?

Using and NRF52832, SDK 15.3.0, SD 132 6.1.1. I have "DEBUG" defined.

    Hi,

    The config is removed because "backtrace" bug is fixed in the GCC toolchain version we are recommending for this SDK release. You can use the SDK release notes to see the toolchains versions we have used for test and verification. 

    What is the fault "id" passed to the error handler? Note that you will not get a backtrace if it is a Softdevice assert (NRF_FAULT_ID_APP_MEMACC/NRF_FAULT_ID_SD_ASSERT)
