I am new to RTEMS. Up to now i have worked with VxWorks and will use RTEMS in future.
I have a couple of mvme-CPU-boards and to get experiences with the development process
of RTEMS i tried to get RTEMS running on this type of boards.

Unfortunately i run into  "Illegal Instruction" calls when it try to run the test-programms like "hello.exe"

Network Booting from: DEC21143, Controller 0, Device 0

I assume that it has something to do with the amount of memory. On my boards i have 64MB and more memory available.
I think one have to use longjumps (gcc -mlongcall). I didn't found the point where i can define the used memory for my boards to get
the right initialization. 

Any idea to overcome that problem ?
