Pogo E02 - Wont boot to USB or Pogo OS
November 04, 2020 06:38PM
Working on a Pogo E02 now having got and V3 & V4 working. Upgraded UBOOT to latest version 2017007 as per instructions but now I can't boot to original Pogo OS or my Debian USB stick. This is the serial terminal dump:

If I manually start usb (usb start) the Sandisk 16GB stick is recognised as is the partition.

I have rummaged around but cant find anything obvious and I can't see anything on the WWW that has helped me so I'm asking the experts.

One other thing, when I copied the envs, I did see an error saying the env table was corrupt and it was using the default. When I look at the saved txt file, there is very little in it unfortunately. One other thing which I stupidly didnt make a note of is that my MTD partitions were laid out slightly differently to your default - I remember that it was the data partition which had a different start.

dev: size erasesize name 
mtd0: 00100000 00020000 "u-boot" 
mtd1: 00400000 00020000 "uImage" 
mtd2: 02000000 00020000 "rootfs" 
mtd3: 0??00000 00020000 "data"

I plan to check the Sandisk Ultra 3.0 in my pogo V4 tomorrow just to check the installation but as far as I can tell, it has no errors and is readable on my Zorin system and of course the mtd file is there.

The USB drive is not recognized by u-boot.

Erm Yes - This is a new stick - it worked for a while when I booted my Pogo V4 with it today then it got stuck. Went back to scratch and this time used FDISK on the pogo V3 to repartition the stick, copied the OS over again and booted the V2 OK however a bit later, on a restart, the Pogo was dead - no lights nothing :( Checked the PSU was OK, plugged it all in again and hey presto - up and running again.

Lessons learnt so far - Don't trust the EXT3 or EXT4 formatting from my Zorin based system, the Sandisk Ultra USB 3.0 are OK on all versions of Pogo, my PogoE02 may have developed a fault.

I still can't boot into the native O/S on the Pogo E02 however. That was working before I upgraded UBOOT. It doesn't seem to look at the NAND area and I wasn't sure if I could use the same script for 'Rescue System Pogo V3'. This is the serial log

No. The Pogoplugs E02 and V3 are very different devices.

It is still not regconized for whatever reason

loading uImage ...
** Bad device usb 0 **

Suggestion:

- Use MBR partition, don't use GPT.
- Wipe it clean on the Pogoplug (whatever unit you have running). Recreate MBR partition, and untar the rootfs (while being root). GPT should work OK. However, take a low common denominator first to make it work.
- If you insist on using GPT then use parted in a running Linux box such as a Pogoplug or on a Linux Mint /Ubuntu VM/laptop. Don't trust any other utility.

Hi Bodhi.The USB stick is now booting correctly after I fdisk'd and format'd on the Pogo V3 yesterday. By last night I was down to dodgy hardware and a Pogo that wont boot onboard rescue from NAND. I should have been clearer - the last serial dump was when I was trying to boot from the Onboard OS in NAND. There were no USB device connected at all (or network cable). I wanted to use the onboard OS for recover like the V3. When I originally raised this question, I thought I had broken the Pogo completely as I couldn't boot anything. Now I can boot to the USB ports I realise it was two separate problems with boot to USB stick fixed. Is it still possible to boot the original NAND OS with the latest UBOOT?

The stock OS is pretty old. If you really need a rescue system, you can install openwrt/lede. There's a thread.

Bob,

Like David said, OpenWrt on Pogo E02 is a much better rescue system than the old stock OS.

Not right away. You'll need to chainload the old stock u-boot image like it has been discussed here recently (there are a few posts that showed how that's being done on a Kirkwood boxes). You will need this stock u-boot image to be saved in the stock rootfs, or some where in NAND. So before installing new u-boot, you should save that while running stock OS. After new u-boot has been installed, a few envs needed to be added to trigger the chainload process.

Thanks David & Bodhi, - I will investigate the openWRT option (I have played with it on the V3 and tftp loaded across my network) once I get my DHCP problem on this EOS fixed (my router thinks the E02 is using a static address).
