My port of U-Boot to a T2081 is hanging when I send a USB command, but only when it is booted from SPI. The NOR boot works perfectly and I cannot see any logical difference between the two.
When I step this with a debugger (Lauterbach) the debugger also hangs but says "Running (MPIC Reset)".
I can't find anything that clearly explains this state in the reference manual.
Could anyone please give me an idea as to what could be going on here?
