Hi,
Yesterday I got a Saber SD (as a second board to my SaberLite).
I've used the imx6qsabresd machine config to create a sdcard.
uboot and kernel look like they are working, but the rootfs is not mountable
during boot.
Here is the corresponding kernel output:
Waiting 2sec before mounting root device...
VFS: Cannot open root device "mmcblk1p2" or unknown-block(179,26)
Please append a correct "root=" boot option; here are the available
partitions:
b300 7757824 mmcblk0 driver: mmcblk
b310 2048 mmcblk0boot1 (driver?)
b308 2048 mmcblk0boot0 (driver?)
b318 3880960 mmcblk1 driver: mmcblk
b319 8192 mmcblk1p1 00000000-0000-0000-0000-000000000000
b31a 262144 mmcblk1p2 00000000-0000-0000-0000-000000000000
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-
block(179,26)
The kernel command line is:
console=ttymxc0,115200 root=/dev/mmcblk1p2 rootwait rw rootdelay=2
(the 2sec delay is added manually as boot parameter to test if it's a timing
issue ... it's the same error without the delay)
Anyone seen something like that?
He obviously has problems mounting mmcblk1p2 ... he finds the device and
partition, but can't mount it.
I can mount and read from it on my desktop, without any problems.
I've tested 2 complete different sdcards, so it's not the sdcard.
I've also tested the android-sdcard which was shipped and that's booting
flawlessly ... so it's not a HW problem either.

Do you also have a SD card connected to SD2 slot? If so, can you
please remove it and keep only the SD card at slot SD3?

The opposite (haven the "same" sdcard in both slots) doesn't help either ;)
VFS: Cannot open root device "mmcblk1p2" or unknown-block(179,26)
Please append a correct "root=" boot option; here are the available
partitions:

I tried to boot from SD2 only.
When switching the DIPs 1 and 2 he loads uboot from SD2, but I can't get
'fatload mmc' working when booting from SD2

Could you post the boot log? There should be messages about what MMC
devices and partitions are discovered by the kernel which could help.

The problem solved itself.
I've unplugged the board (to do something else) and re-plugged everything to,
exactly as before, with the same sd card and everything ... to get the full
kernel log
Now he's booting flawlessly ... it was either a loose cable (where it's hard to
see which cable could have been loose) or one of those position-of-moon-and-
stars problems ;) ... maybe it was due to playing around with DIP1 and 2...
Anyway: Thanks for the Help!
