how do you partition and format the CF card?
--- Mingquan Pan 2011-11-08 01:02:55
I do this by running fdisk /dev/sda after kernel booting up.
Once it changes the partition numbers in kernel, then run reboot, in the
following uboot, it fails to detected the cf card like above. but if you do
reset remotely by host machine parallel port or power down and then on, it can
recognize the cfcard ok.

It looks the reset PIN on CF interface is not driven when kernel reboot. The CF
card stays in some state that can't be probed properly.

This should be a bug in kernel.

There is no problem to probe and mount CF card via PATA_PCMCIA driver in
So, this is still a uboot bug. The CF card is not reset properly if run reboot

Don't run this test with the Kingstone 512M CF card. It is not supported by the
