atlenisse,

i also use ocidec to replace altera cf card. although i use ocidec driver in uclinux but i don't see the same boot messages as yours. it will halt after "ocidec v3.1" message. could you tell me whether you have to do some modifications in ocidec driver or only by default? i use uclinux 2.6.11 kernel .

thanks.

sam

I have tested the altcf core with IDE harddisk on many custom boards.

It is straight forward.

If you want faster io timing, just edit the ptf.

Why do you want to use ocidec ? I didn&#39;t see any advantages.

Please note it takes time to copy buffer by CPU, and it is very slow.

You should use mmap() to improve performance.
