Compact Flash on Cyclone II

993 Views

Hi,

Does anyone used the Compact Flash under linux with CycloneII (EP2C35F672C6)?

Apparently the CF is detected but the probe fails. I have the following messages when booting:

ide: Assuming 50MHz system bus speed for PIO modes; override with idebus=xx

CF: ctl=1

hda: no response (status = 0xfe), resetting drive

hda: no response (status = 0xfe)

hdb: no response (status = 0xfe), resetting drive

hdb: no response (status = 0xfe)

CF register fails

Any clue ?
