Stuck on waiting for root device...

Finally got around to gaining SSH using serial method. All seemed to go well.

Used "Updated 24 Feb 2015" @ http://forum.doozan.com/read.php?2,12096 to create on SD card.

Looking at serial console everything seems to go good until:

Begin: Waiting for root file system ... done.
Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)
ALERT!  /dev/mmcblk0p1 does not exist.  Dropping to a shell!

Any input on solution greatly appreciated.

Is this the Pogo V4 box?

That's the 3.18.5 rootfs. Not the latest, but it should be OK.

So you do have serial console.

1. Power up, interrupt serial console and

printenv
boot

Please post the entire serial log, from u-boot banner until the initramfs prompt (this is where the rootfs could not be mounted, so the kernel throw you out to the temporary rootfs).

Note: whenenver you have booting problem, you should always post which box, and the entire serial log and u-boot envs. It will help me pinpoint the problem quicker.

Yes, it is the Pogo V4. My bad, should have stated that.

Yes, started out with older version. Had issues with newer so picked it at random:)

Unfortunately no boot:(

:) the problem is easy to solve if you do this:

Ok, thank you. Here is what I get after interrupt:

Susan,

Yours is an older version of u-boot. Again, posting the serial log from the u-boot banner would help telling me right away which version. For example, the log should begin here:

Quote

U-Boot 2016.05-tld-1 (Jun 12 2016 - 13:41:47 -0700)
Pogoplug V4

But based on the envs, looks like 2014.xx version?

Here is the problem:

1. You have chosen to boot with the DTB appended to uImage

mmc_boot=mw 0x800000 0 1; run mmc_load_uimage; if run mmc_load_uinitrd; then bootm 0x800000 0x1100000; else bootm 0x800000; fi
mmc_init=mmc rescan
mmc_load_uimage=ext2load mmc $device 0x800000 /boot/uImage
mmc_load_uinitrd=ext2load mmc $device 0x1100000 /boot/uInitrd

But, the DTB that was appended to uImage was an incorrect file:

[    0.000000] Machine model: Seagate GoFlex Net

So in the rootfs that you have (3.18.5-kirkwood-tld-1), you need to redo the uImgage to append the Pogo V4 DTB

Quote

4. Create uImage with embbeded DTB (If this is not first time installation, please see Note 2 below).

I'm using the GoFlex Net booting with USB drive as an example here. Please replace its name (kirkwood-goflexnet.dtb) with the box you are installing on (for example, kirkwood-pogo_e02.dtb). Look inside /media/sdb1/boot/dts/ for the correct DTB file name for your box.

cd /media/sdb1/boot
cp -a zImage-3.18.5-kirkwood-tld-1 zImage.fdt
cat dts/kirkwood-goflexnet.dtb >> zImage.fdt
mv uImage uImage.orig
mkimage -A arm -O linux -T kernel -C none -a 0x00008000 -e 0x00008000 -n Linux-3.18.5-kirkwood-tld-1 -d zImage.fdt uImage
sync

That bold line above should have been:

cat dts/kirkwood-pogoplug_v4.dtb >> zImage.fdt

So you don't need to install new u-boot yet. Just redo the uImage as I described above and it should boot. If it still throw you out to initramfs, then we can add another bootarg to help the kernel to find the right rootfs.


BTW, with the new u-boot (20116.05), the u-boot envs are set up to find the rootfs automatically. The version you have installed did not.

Arggg:) Now I cannot get SD card to mount even after format.

Think been at this way too many hours today, time to rest the head. Will get back on this tomorrow and try again.

Will follow your new instructions (if can get SD card to mount) and report back. Thank you so much for help.

Susan

Your help solved the issue bodhi, thank you!

Now I will have to read up on installing new uboot and debian. Basically all I am wanting to do is setup PHP development area (and attached two USB drives) so we can use it in classroom project.

Thank you again,

Susan
