Hello everybody, I've got a problem with my attempts to port eCos to our MPC855T board:
I started with the FADS template (which I now know, was not the best idea) and got so far that I can access my RAM, my FLASH, the UARTs and the FEC (at least I can see the DHCP requests on the net). When I compile the 'twothreads' example, I can find a bunch of threads in the internal threadlist, obviously everything fine, some 'SLEEPING', some 'RUNNING'. But after each thread has run once, the processor is only looping throug the main_idle_thread() and it's doing nothing else. The trace issues the following a short time before the endless 'loop' (where the 'loop' is probably triggered by an external interrupt). TRACE: <2>[447]void Cyg_Mutex::unlock() return void TRACE: <2>[709]void Cyg_Alarm::initialize() enter TRACE: <2>[277]void Cyg_Counter::add_alarm() enter TRACE: <2>[277]void Cyg_Counter::add_alarm() RETURNING UNSET!

I probably missed something, but what? Any help is appreciated!
