Hi,
I'm trying out u-boot-2010.06 and linux-omap-2.6.34, and I'm using the omap3_defconfig.
I get the following error upon boot:
[ 2.097320] Waiting for root device /dev/mmcblk0p2...
[ 2.235595] mmc0: new SD card at address b874
[ 2.243530] mmcblk0: mmc0:b874 SU02G 1.87 GiB (ro)
[ 2.250213] mmcblk0: p1 p2
[ 2.323638] VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2)
[ 2.330871] Please append a correct "root=" boot option; here are the available partitions:
[ 2.339477] b300 1971712 mmcblk0 driver: mmcblk
[ 2.344848] b301 40131 mmcblk0p1
[ 2.349182] b302 514080 mmcblk0p2
[ 2.353973] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
What could be wrong? I have set the correct root device which is /dev/mmcblk0p2.
Here are my environment variables:
