I am bringing up eCos on a PXA3xx family part and have been tracing some issues with threads starting up once the scheduler is going. I can trace execution through context.S up to the "movs pc, lr" after which, the system hangs. If I change the movs to a plain mov, the code will continue and my thread (only my first as my timer isn't working right now, but that is a different problem) will start up. Can anyone explain why a movs is used and why it might be causing the system to hang?
