Soft error not catched in app_error_handler

[Sébastien Despont]

Hello,

When I check RESETREAS, I have some reboot reasons rised from software error (SREQ).

I know that these errors are not catched in the app_error_handler because I use the GPREGRET to retain the information as explain in this topic.

After looking at the reference manual, I didn't find any information about what kind of error can cause a software error not catched in the app_error_handler.

Is the softdevice which causes theses errors?

I am using nRF52832 with SDK11 and softdevice 132 2.0.0

Best regards

you sure it is not a hardfault? you could try catching it in debugger.

[Sébastien Despont]

Yes, it could be but the error is really not easy to reproduce, so I can't confirm in the debugger. Can I find somewhere a list of behaviour throwing hardfault errors?

[Wojtek]

Could be many causes. Most of my hardfaults were caused by memory leakage or were somehow connected to wrong operation (my fault, not the SD) of softdevice. Also, things like unaligned memory access (not sure if it fires hardfault on cortex m4 by default), stack overflow etc...
