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
I2C: ready
DRAM: 16 MB
FLASH: 8 MB
In: serial
Out: serial
Err: serial
Net: SCC ETHERNET
PCMCIA: 3.3V card found: SunDisk SDP 5/3 0.6
Fixed Disk Card
IDE interface
[silicon] [unique] [single] [sleep] [standby] [idle] [low power]
Bus 0: ............................................................** Timeout **
Type "run flash_nfs" to mount root filesystem over NFS
Hit any key to stop autoboot: 0
=>
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.
