Dear Support,
I have an AM3352 custom board which has a SD card on port 0 and a eMMC on port 1 (as in the beaglebone black).
The mmc 0 is partitioned as follows:
Partition Map for MMC device 0 -- Partition Type: DOS Part Start Sector Num Sectors UUID Type 1 63 144522 00000000-01 0c Boot 2 160650 3743145 00000000-02 83
I am not able to boot the kernel from SD card since the filesystem is not found and I get:
[ 2.662186] Please append a correct "root=" boot option; here are the available partitions: [ 2.671052] b300 3776512 mmcblk0 driver: mmcblk [ 2.676685] b301 3774447 mmcblk0p1 fc4854ef-8d93-ec43-bdef-11bd350d61d6 [ 2.684586] b310 16384 mmcblk0boot1 (driver?) [ 2.690185] b308 16384 mmcblk0boot0 (driver?) [ 2.695799] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
The SD card has two partitions, one for MLO, u-boot and zImage an the second ext3 partition for the rootfs.
I am able to list files of the rootfs from u-boot.
U-Boot# ls mmc 0:2 <DIR> 4096 . <DIR> 4096 .. <DIR> 4096 tmp <DIR> 4096 srv <DIR> 4096 var <DIR> 4096 lib <DIR> 4096 proc <DIR> 4096 run <DIR> 4096 mnt <DIR> 4096 media <DIR> 4096 boot <DIR> 4096 dev <DIR> 4096 bin <DIR> 4096 usr <DIR> 4096 etc <DIR> 4096 sbin <DIR> 4096 home <DIR> 4096 sys
The kernel support the ext3 filesystem.
I'am going crazy since I don't understand the reason since the filesystem is not seen by the kernel.
Below the environment and the boot messages until the kernel hangs.
Thank you in advance for the support!
