[next] Failing Odroid XU3 boot due to missing MMC device

[Krzysztof Kozlowski]

Hi,


Anyone also observed recent failures of linux-next (20160413, 20160414)
on booting from SD card? On my Odroid XU3 exynos and multi_v7 configs
fail with:

Apr 14 07:52:53 starting version 229
Apr 14 07:52:53 :: running hook [udev]
Apr 14 07:52:53 :: Triggering uevents...

Apr 14 07:53:05     Type 'exit' to try and continue booting
Apr 14 07:53:05 sh: can't access tty; job control turned off

I didn't start bisecting yet... maybe this is known?

Re: [next] Failing Odroid XU3 boot due to missing MMC device

[Markus Reichl]

Hi Krzysztof,

yes, observed this with linux-next from yesterday 13.

I boot from eMMC.
Device numbering of eMMC and SD are exchanged now.

I solved the boot problem by changing the rootdev in U-Boot env
from /dev/mmcblk0p2 to /dev/mmcblk1p2.

Changed /etc/fdisk, too, to mount /dev/mmcblk1p1 to /boot.

You really should mount by partition uuid - supplying something like:

	root=PARTUUID=f3ae567e-02

on the kernel command line.  This makes the mounting of rootfs
independent of which device carries the filesystem.

If you're not using an initramfs, the kernel prints the partuuid
values if it doesn't find the rootfs.  I don't know how to get the
partuuids without going through that process, sorry.
