Normally it should be active by default. Is CONFIG_KERNEL_ELF_CORE set

It was not activated, but the output from gdb looks not so helpful:

GDB is unable to find the start of the function at 0x77d79ed5
and thus can't determine the size of that function's stack frame.
Did you remember to provide it with a unstripped "netifd" binary from the

(or did you try with the stripped final binary in build_dir or router? which
will fail unless you have disabled stripping and have the full binary intact)
