pcmcia card not set up by u-boot on tqm823l
Dear all,
I am having problems with u-boot setting up a pcmcia card on a tqm823l on an Stk8xxl starter board. From a "make TQM823L_config; make" version of u-boot 0.4.0, I get the following output when booting the board:

The same is seen with another flash card. The code that times out is in common/cmd_ide.c (at bottom of message) and it looks like the card is saying it's busy. Does anyone have a suggestion as to why the cards aren't being correctly set up/recognized?

Seb James.

Ok, the problem was the bdi setup files that I was using to program u-boot onto my tqm module.
The bdi setup files (TQM8xxL.cfg and reg823.def) caused odd problems such as the one above and also the problem I was having with an rtai module not functioning.
I'm happy now.

Probably the card does not work, at least not in an ATA standard conforming way. There is little you can do when the BUSY bit stays on forever after a device select command...

Check the SIUMCR settings. Some modes (debugging / PCMCIA) are mutually exclusive.
