So I am trying it out in u-boot first. I wrote a u-boot command called mynand which writes the command at 0x30000000 (socket1 of pcmcia), data at 0x20000000(socket0 of pcmcia) and address at 0x20000040(i.e Address6=ALE). But u-boot hangs whenever I try to access pcmcia socket addresses i.e. 0x20000000 or 0x30000000. And I did "md 0x20000000" It too hangs the u-boot. Please suggest me how to go on further. Waiting for your responses. Thanks & Regards Girish ---------------------------------------------------------------------- "When Ability Ends; Faith Begins....
