Can u-boot see the partition formatted with ext2?
Can you mount an NFS root filesystem and access the card normally? Or
is it just when you use it as your rootfs?
How did you create you partitions and format the CF card?
And like somebody else mentioned, if you are really going to use this
for an embedded system, you are going to want to rethink your
Maybe something like:
p1 fat12 - kernel and binary image
p2 ext2 - read only rootfs
p3 ext3 - non volatile, slow rate data rootfs
p4 tmpfs - volatile, high rate data rootfs
