Good News / Bad News time

Good News
I can serial console to the unit and extract the settings listed below. it appears to be running the later uboot
U-Boot 2014.07-tld-2 (Sep 20 2014 - 00:52:18)
Pogo E02

Bad News
The env settings seem to be all over the place and are attached to this post - what can be seen on the console is the following, which is a good start

U-Boot 2014.07-tld-2 (Sep 20 2014 - 00:52:18)

PogoE02>

can anyone offer a simple solution to input a set of env statements from the console that will allow me to boot a debian stick from which i can then reflash all the settings to get this working again??

I guestimate it will be something like the following, however it doesn't work.
usb reset
setenv bootargs root=/dev/sda1 rw rootwait mtdparts=orion_nand:1M(u-boot),-(rootfs)
load usb 0:1 0x810000 /boot/uImage
bootm 0x810000

The debian stick outputs the following

PogoE02>  usb reset

The env settings look to be a mashup of both Arch and Bodhi settings and i dont have the knowledge to correct this on my own, it would be a shame to consign a Pogo to the bin when what looks like an environment variable mashup that COULD be sorted.

:)) It happens!

Use this to reset the envs to a default state in serial console:

Bodhi, THANKYOU for the link, i will attempt this tomorrow and if all goes well i will rejoice in the knowledge of another Pogo saved from the parts bin.

@ "Mr Bodhi"

Thankyou!!

Ii now have the unit up and running again - its not a pain i would like to go through too often tho....

as i type this i am prepping the image for the keen new user of the forum.

@Gravelrash,

Please don't be offended if my questions sound like I'm against the idea of an image for noobs (or even doubting your technical ability). I'm agnostic on this. IMO, I think people who starts hacking Linux should at least learn how to create a bootable rootfs with tar, fdisk,.. commands on Live CD, or a Ubuntu box. OTOH, I understood the appeal of the rPi community approach with an image.

- Have you thought through the issues of different versions of u-boots on a given box?
- An image can only target a specific box such as Pogo E02, Pog V4,.... To make it Kirkwood-wide, it will require a modern u-boot and scripting. Are you planing to create an installation script?

Just food for thought. It's not an argument against the idea.

PS.

Also, I should mention that davygravy already has released an image (older kernel version and less number of Kirkwood boxes support). Perhaps that could serve as an idea in this.

@Bodhi

Im far far from offended at you comments. I totally agree with you when you indicate that the best practice would be for the user to go through the learning curve, i imagine that at some time or other all of us have been through it.

My intention is to offer help to an obviously keen and lesser skilled linux user than I in the most altruistic of fashions, in that, this forum has offered me so much help and support, that if i can offer a "helping hand" to someone else then karma demands it.

It will definitely be aimed solely at one particular box the Pogov2 with the 2014* uboot. the image would include in an installation directory with the binaries/software tools necessary to upgrade the uboot to this level (taken from the arch install routinet). Without an installation script to do the work for them. From what i can gather arch to debian seems to be the way users on here go. (personally i run 4 different distros on my devices as each distro has its pro's and cons)

I dont have the time or resources to make anything more than a "one off" and certainly wont be taking it to the level or the Rpi! Much as i would want to :)

Tip of the hat!

I think this specific target is good (as widely used as the V4/mobile, if not more so), and achievable without too much effort.

@bodhi

Do you have a link to the image and install routine issued by davygravy. I'd like a look.
