nand with pcmcia interface

[Girish]

Hi all ,
    I am writing a driver for 256MB Micron Nand flash On PXA270 board 
through PCMCIA interface as decribed in 
"http://download.intel.com/design/pca/applicationsprocessors/applnots/28014402.pdf". 
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

You should ask about this on the u-boot mailing list.
