Bootloader DFU Example | Crash

[niecorex]

I am trying to run the example secure_bootloader\pca10040_ble_debug. The application does crash during a debug print with following stack trace:

#0  app_error_fault_handler (id=id@entry=16386, pc=pc@entry=0, info=info@entry=536936296) at ../../main.c:88

#5  0x00074b3c in main () at ../../main.c:129

Any idea what could be the problem here?

Best regards,

Nico

Hi,

I haven't seen this before and it also seems a bit strange that logs are skipped already at the beginning of main(). Are you testing with the original project, or have you made any changes that might be relevant? Could it make sense to test this again with a new copy of the SDK? 

Thanks,

Vidar

This happens in a clean repository of 'nRF5_SDK_15.3.0_59ac345' to me but seems to be fixed in the demo of 'nRF5_SDK_16.0.0_98a08e2'. Will keep working from here. Thank you!
