first of all sorry for my bad english.
i installed archlinux arm on my pandaboard an having trouble to get it started from sdcard.
it successful finds the boot device (fat16), executes the boot.scr scripte and loads the Kernel-Image (uImage copied from rootfs). The kernel is decompressed, loaded fine and tries set up the board. But it hangs on waiting for root device
The output of the serial console while booting (usb device still attached, but behavior if not):
$this->bbcode_second_pass_code('', 'OK
OK

When booting the same rootfs image on usb it showes the image from 28th June.
$this->bbcode_second_pass_code('', '[root@alarm mnt]# uname -a

when on booted on rootfs on usb and i try ls on /dev/ the mmc block device is missing. so it seems like a problem with the kernelmodule?

i found this, which seems the same problem, but the config options are set in kernel
$this->bbcode_second_pass_code('', '[root@alarm mnt]# zcat /proc/config.gz | grep CONFIG_DMADEVICES
CONFIG_DMADEVICES=y
# CONFIG_DMADEVICES_DEBUG is not set
[root@alarm mnt]# zcat /proc/config.gz | grep CONFIG_DMA_OMAP
CONFIG_DMA_OMAP=y
')
the boot.scr of sdcard-rootfs
$this->bbcode_second_pass_code('', 'fatload mmc 0 0x80300000 uImage
setenv bootargs console=ttyO2,115200n8 noinitrd init=/sbin/init root=/dev/mmcblk0p2 rootwait rw loglevel=8
bootm 80300000')
for usb i exchange root=/dev/mmcblk0p2 with root=/dev/sda1, rest the same.
i also tried another sdcard, both are booting the fat16 bootfs, and hangs with same output. when changing to usb both are booting.
After googling around i'm out of ideas, so i would be very thankful for every idea.
Thanksand greetz,
Shawn.
edit:
after i found the ext2ls command of uboot i tried it on my sdcard (fs is ext3)
$this->bbcode_second_pass_code('', 'Panda # ext2ls mmc 0:2
<DIR> 4096 .
<DIR> 4096 ..
<DIR> 16384 lost+found

')
So the sdcard seems fine and the board can read it...
Maybe only a missing module or something like this?
Greetz.
