Hello,

i've set up a micro SD card with VFAT on partition 1, EXT2 on partition 2.

Partition 2 is buildroot's output/images/rootfs.ext2, copied with "dd" to the 
micro SD card.

On partition 1 i have u-boot and i start the kernel like this:
mmc init
mmc rescan 0
run loaduimage
bootm 0x82000000

Then i see the kernel boot log and i see it hanging:

[    1.215850] twl_rtc twl_rtc: setting system clock to 2000-01-01 00:05:25 
UTC (946685125)
[    1.226806] Waiting for root device /dev/mmcblk0p2...
[    1.369873] mmc0: host does not support reading read-only switch. assuming 
write-enable.
[    1.389953] mmc0: new SDHC card at address e624
---> no more output


I use buildroot-2011.02, the kernel is 2.6.37.

In the kernel configuration i have set:

TI OMAP Multimedia Card Interface support (MMC_OMAP)
TI OMAP High Speed Multimedia Card Interface support (MMC_OMAP_HS)


Can anybody give me a hint why the kernel does not continue to boot?


Best regards,
Torsten.
