PCMCIA timing prob.

[Hyun-Joon Cha]

Hello.

Someone has kindly responded that I have to upgrade RPX Utility software to change SYPCR value.

As suggestion, I changed SYPCR to make it's maximum value of BMT - 0xff - with a BDM.

And I tried several values for clocks then I got some messages from cardmgr which is somewhat hopeful.

What's the meaning of Anonymous memory?

To be sure, I have read all the posts about PCMCIA in this group and applied all patches from ftp://ftp.absolval.com/rpxlite.

My board is RPX Lite 850 SR and I used Xircom CE3-10BT and 3Com 3CCFE574BT cards.
