Solved the issue. Had a peripheral that I had connected to the SCK pin. Unstuffed it, and it seems to be ok now.

Thanks Turbo J

I have "-flto" commented out as it's caused some similar issues in the past.

I'll double check the priority, I haven't mucked with it but at this point it's likely to be something like that..

The error location is in softdevice, and "funny looking string" is probably just a NULL pointer.

There might be problems in the SPIM interrupt handler - e.g. the handler function did not get picked up in "-flto" mode or an .o module (for the SPIM) is not linked properly.

The default handler would cause a infinite looping in the handler function, which does not allow main() to run and thus cause a timeout in the softdevice.

Another possible cause: Wrong interrupt priority. The default (0) priority is reserved by the softdevice.
