Ok,
       So I was using the microwire controller on omap and used spidev by 
Andrea P. I connected the microwire pins to my device. I performed reads and 
writes to my device but all I get are 0s (same as when I do not attach any 
device to the microwire pins). I probed the pins using a logic analyzer and 
when I perform reads or writes, the CS pin is the only pin that gets signals 
(It goes active low when I perform reads and writes which is correct). The 
other pins do not get any signal at all. Even the clock is always low.

Could anyone tell me what could be the reason for this please?

Thanks,
Lizette
