So, if I understand correctly, the demos work when booted from the SD card, but
it fails when you load it through the debugger....My guess is that there is a
problem with the configuration when you do a debug load.
Have you tried loading the file via the serial method of the MLO?
I didn't really get that deep into debugging. I just echoed strings to the
serial console from the MLO, which was the application I was working on. I then
switched to Linux development because I needed complex USB drivers and didn't
want to roll my own at that time.
