Pogoplug E02 - Warning - readenv() failed, using default environment

Hi,

my second Pogo has this Error:

Can I repair this?

@droidbox,

You can't completely repair this. The bad block is at the env location for this u-boot version. And also is for my u-boot build images. It's a common location we've chosen for these Kirkwood boxes.

However, there is a work around that will allow you to boot successfully. I'll post the instruction later today.

Hi Bodhi.

This is really nice. Thank you very much in advance.

droidbox

droidbox,

You are running Jeff/davygravy u-boot build so I need to see the default envs. Please interrupt serial console and print out your u-boot envs:

u-boot>> printenv

Hey bodhi.

I have run on a new Pogoplug the follow steps

droidbox,

These are the relevant default envs:

arcNumber=2097
bootcmd=run bootcmd_usb; usb stop; run bootcmd_pogo; reset
bootcmd_usb=run usb_init; run usb_load_uimage; run set_bootargs_usb; run usb_boot;
usb_boot=if ext2load usb $usb_device 0x1100000 /boot/uInitrd; then bootm 0x800000 0x1100000;else bootm 0x800000;fi;

usb_device=0:1
usb_init=usb start
usb_load_uimage=mw 0x800000 0 1; ext2load usb $usb_device 0x800000 /boot/uImage
usb_root=/dev/sda1
usb_rootfstype=ext2

So download the latest rootfs (3.17). And then put it on an EXT2 USB drive, following the instruction. And boot with it. Please capture serial console output and post here.

Your bad block is right at the envs location, so this current u-boot won't help in setting any env. My latest u-boot build won't be able to help either. Your defaut envs are good enough to allow booting single USB drive formatted with EXT2.

My future u-boot release will allow full customization without using the NAND env block. But I need to find time to release it :) The most time consuming part were done (I'm running it or a couple months), but I still need to write instruction for the new features.

I think you'll need to stick with one method of booting. Either with embeded DTB, or with separate DTB. The instruction mentioned that :) So choose one and get it booted first.

droidbox,

The new u-boot version would solve your problem with the bad NAND block at 0x000c0000:
http://forum.doozan.com/read.php?3,12381

See the instruction in section B and D. Basically, you need to copy the file uboot.2014.07-tld-2.environment to uEnv.txt and put it in /boot directory.

Did you use the uEnv.txt to boot into Debian sucessfully?
