Hello Peter,
I made some changes and since then I haven't seen this any more.
....don't know what the reason was....
Thanks!

Best regards
Neo

Hi Neo,

unfortunately I don't have an idea out of my head. Which board do you use for development? Obviously you landed in the cortex common panic handler:

https://github.com/RIOT-OS/RIOT/blob/master/cpu/cortexm_common/panic.c#L34

It would be great if could share your code so someone (e.g. me) could counter check.

Best regards
Peter

Hello to everyone,
during the porting of the MRF24J40 driver i get the following
error-message:

*** halted.

Inside isr -13


The failure happens, when I use the command ifconfig without parameters
in the gnrc_networking example.
Has anyone an idea about the reason of that fault?

Thanks,
Neo
