Hi Xlking,

Are you using the Linux core Microtronix provides, or your own customized core? It looks like the driver could not get correct data from the CF card.

If you are using a Cyclone board from Altera, the booting message "CF: ctl=1" means the CF controller is not powered, thus won't work correctly. You need a message like "CF: ctl=3" in order to make the Linux driver work. I am inclined to think it is a hardware issue.
