I don't know anything about the 5200 board, but I recently wanted to do
the same thing with the LED's on the Wind River (EST) SBC8260 board.
The LED's on this board are write-only at a specific address. My
solution was to write a simple loadable module (like a device driver,
but not statically linked to the kernel). Once loaded, any application
can write to the LED's by writing to the module in /dev.
I can send you my code as an example if you want it.
