[U-Boot-Users] pcmcia card not set up by u-boot on tqm823l

[U-Boot-Users] pcmcia card not set up by u-boot on tqm823l

[Seb James]

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:


U-Boot 0.4.0 (Sep  9 2003 - 12:27:42)
 
CPU:   PPC823EZTnnB2 at 50 MHz: 16 kB I-Cache 8 kB D-Cache
Board: TQM823LDBBA3-E50.308

DRAM:  16 MB
FLASH:  8 MB

=>


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?

regards,

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.
