Yeah, its the one you sent me. I'll try a different one tommorrow.

any progress / result with that?

Yes, I've tried using a different phone and it works fine.

Holger and I have discussed your problems yesterday, but we really don't have an idea at this point.

Some (relatively stupid) ideas to debug it:

1. does hello_world.bin work for you at all?

Yes.

2. what happens if you change the timing, i.e. add a couple of delays to see if the reboot happens after a certain fixed wallclock time or really depends on the code that is executed

I've tried disabling the tpu_end_scenario() call, which avoids the crash. My understanding is that the new settings are not activated without this, so I guess a good spot would be to add some delays directly after the tpu_end_scenario() call to see if the crash happens within the interrupt handlers?

3. what about using layer1.bin and the layer23 program on an ARFCN that is produced by OpenBSC + nanoBTS? This is the most frequently used setup by Dieter, Holger and myself so far. This way we can exclude the possibility that something received from the real operator GSM network in your location causes the problem

I'll give that a try.

Thanks!
