Actually, the loopback test should work without the clock (as there is
no real device connected, that would need the clock).

I don't know the eval board and it's default eCos setup, so I can only
suggest that you should check the SPI remapping configuration (AFIO, see
STM32F10x Reference manual 8.3.10 and 8.3.11). Maybe the signals are
being remapped and therefore routed to other GPIOs.

Cheers,
Manuel
