pogoplug minimal debian root fs required

Hello all,

I have a black pogoplug (no WIFI model) and was successfully running Debian Squeeze for several days. I installed uBoot, left the internal flash untouched and booted Debian off a 4GB USB flash drive.

All was good until my device stopped booting into Debian. uBoot netconsole shows by /boot/uImage and /boot/uInitrd loading successfully, and once the kernel starts booting I lose netconsole and I can't troubleshoot any further. I tried mounting the flash drive on my debian laptop and edited /etc/rc.local and /linuxrc to "touch /tmp/foo". No /tmp/foo is created and I conclude that the kernel is not mounting the root fs.

I tried reinstalling Debian from scratch, but my pogo plug is not successfully getting registered to my.pogoplug.com account. I'm currently having a support case open, but there's no progress so far. I can't activate sshd on the pogo firmware and unable to start the Debian install from there.

I don't have a 2nd pogoplug to rescue my box :-(

1. Is there any way I can debootstrap my pogo rootfs from my x86 Debian laptop? I can debootstrap the first-stage but don't know how to complete the second-stage as I'm running on a different arch. I also don't know how to generate uImage/uInitrd components.

2. Can someone please give me a tar ball of a base Debian install image for pogoplug? I can extract this to my USB flash drive and get going from there on.


Thanks in advance for any help!

I seem to be having the same problem again. Pogo E02 is not mounting root fs on USB.

I'm using latest uBoot:

U-Boot 2014.07-tld-2 (Sep 20 2014 - 00:52:18)
Pogo E02
gcc (Debian 4.6.3-14) 4.6.3
GNU ld (GNU Binutils for Debian) 2.22

and Debian-3.18.5-kirkwood-tld-1-rootfs-bodhi.tar.bz2 rootfs. Rootfs is extracted to a 8GB PNY USB stick, all other USB devices are removed.

Starting kernel ...

Past this point I loose all network access. Kernel is not mounting rootfs on /dev/sda1. The front panel LED flashes green while U-Boot is running and stays solid green once the kernel boot process begins.

I'm unable to progress after uBoot. Please help!

See my signature for appropriate rootfs (depending on which Pogo you have , Kirkwood or Oxnas). Use a Linux box to extract it to the USB following the instruction exactly.

I missed the "Creating uImage with embbeded DTB" step.

Thanks bodhi, it works perfectly now.
