Hi , Through PCI 1520 am detecting compact flash presence..u-boot does nand
probing then if try
command  nand  read <...> or nand write <....> says error , any one has
faced problem like this ....
How to verify read/write blocks on CF.
Kind Regards,
Rangaraju.

Compact Flash support has nothing to do with NAND. You must be mixing
unrelated code and/or events here.
