Pogoplug boot problem

I have a Pogoplug E02. I mess around with uboot with fw_setenv and it does not boot up anymore. (no response to SSH, no status light on the device, IP assigned to pogoplug) I could netconsole to it and it shows the following when i reboot.

This was messed up:

bootcmd=usb=start

You can interrupt netconsole and use setenv to reset it to correct value. Should be something like:

bootcmd=usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run rescue_bootcmd; run pogo_bootcmd; reset

Also, arcNumber 2097 is OK to get it to boot. Later if you have Pogo E02 support kernel then change it to the E02 number 3542.

Hi bodhi,
It looks like solve some problem. However it cannot boot into arch linux. it stuck into starting kernel... It seems like something to do with "file not found /boot/uInitrd"

modified env: (I also set setenv usb_rootfstype=ext2 but it does not show into config...)

Starting kernel ...

Timmypro,

Arch Linux ARM does not use uInitrd. So that's not the reason. I would suggest to get the latest Arch rootfs, and create a new USB rootfs with it (instruction at Arch site). And if it does not boot, try using Davy's Debian rootfs (http://forum.doozan.com/read.php?2,7676). It's good to know you can boot with the USB thumb drive that you are using, and then worry about Linux distro.

FWIW, I had exactly the same problem on a dockstar, the only difference being a Linux-3.1.10-16-ARCH kernel.

I'd get to the "Starting kernel ..." line, and that'd be the end of it.

No further chitchat on the wire, wouldn't respond to ping or ssh. When I pulled the USB stick the dockstar would boot into the default seagate linux.

My error turned out to be really simple.

I was missing the usbrootfstype in the environment, even though I knew I had set it to ext2.

And that was the key: I had set usbrootfstype with the command:

fw_setenv usbrootfstype=ext2

which looks plausible but is wrong.

The correct invocation is:

fw_setenv usbrootfstype ext2

After which

fw_printenv usbrootfstype

returns: usb_rootfstype=ext2

... and now my dockstar boots from the usb stick.

Wouldn't have noticed that the usbrootfstype was missing had Timmypro not mentioned the fact. :-)

So there are two ways you can be SOL on a USB storage device while being only microscopically away from success:

1) format the usb stick as ext2 but set the usbrootfstype to ext3 (as instructed by one of the alarm pogoplug install pages; it seemed strange at the time, but I assumed that ext3 probably covered ext2 as well ... until I came across this link: ).

That's why I knew I'd set usbrootfstype ... because I'd looked, and it was set to ext3.

2) use bad syntax for the fw_setenv command.

ie when I re-set usbrootfstype from ext3 to ext2, I used bad syntax, and fw_setenv deleted the env variable.
_____________________________________________________________

Y'know, it wouldn't be a bad idea for fw_setenv to complain about garbage chars at the end of the line; instead, it seems to take the '=' as the line or option terminator, interpret the command as:

fw_setenv usbrootfstype

and understand that to mean "delete the environment variable."

All sorts of havoc can flow from what seems to me to be a fairly natural error. After all, the syntax for unix environment variable assignment is VAR=value, so even if one knows better, it's easy to slip.

Alternatively, fw_setenv could by default echo back the env variable it changed, and the value assigned to the variable.
