[U-Boot] MPC8541 SPI through CPM

Hi all,

Im trying to use SPI through CPM in my MPC8541 board.

I haven't see support for this combination even in the newest U-Boot. So I followed MPC8555E Reference Manual, but I'm having some problems:

- I can see the clock and chip select (using a osciloscope) but data out (MOSI) is always zero.

- If I use chip select from CPM (SPISEL, dedicated pin), instead a simple GPIO, I got a "Multiple Master Error", as if it was reading the pin.

Any help is welcome, thanks!
