Pogoplug E02 upgrading U-boot. Bad block detected.

Hi,

I was reading the guide on how to update the uBoot for Pogoplug E02. And I've detected bad block.

1. What should I do?
2. Also is it safe to upgrade the uBoot from Archlinux on usb or do I need to unplug all usbs?

[root@alarm ~]# dmesg | grep -i 'bad'
[    7.269250] Scanning device for bad blocks
[    7.301153] Bad eraseblock 366 at 0x000002dc0000

1. This bad block is way out in other areas in NAND (the address is 0x000002dc0000). mtd0 is the 1st 1M.
2. Install u-boot from Arch USB.

I've made it all the way through the guide. I think It has installed, I'm not entirely sure.

Netconsole setup isn't working, I followed the directions on Jeff's guide. I'm booting directly into the Archlinux usb. The pogoplug just blinks orange without the USB plugged in, is this normal behavior? The pogoplug would boot before without a USB plugged in and I could ssh into it, this time I can't.

It is best that you post the log of your installation if not sure.

Normal. Without USB it will try to boot into Pogo OS. With USB it will boot into Debian.

Here is the screen output (I'm not sure where the logs are kept).

What do you use for netconsole server? another Linux box or Windows/Mac? does the server "see" the Pogo E02 (can ping it). And once you booted into Arch on Pogo E02, can you ping the netconsole server box?

I thought it was necessary in case I break something as per the instructions.

10. Set up netconsole. It's important to set up neconsole if you don't already have serial console connected.

I'm trying to learn as much Linux as I can with this pogoplug and I'm more than likely going to breaking somethings as I go.

As for the netconsole, it turns out I skipped installing the default boot environments because I thought it was already default (I just recently put Arch on it.) I finally got netconsole working after installing the default boot environments.

Thank you for your help. Really appreciate it.

I meant what program do you run for netconsole server (Windows, Mac, Linux nc, netcat, bsdnetcat, ...)! not what purpose do you use netconsole for :))

I thought it's funny how the proposition "for " put in the wrong place would have a totally different meaning :)

Oh lol. Sorry I misunderstood. I am using linux. I can't seem to get it to work for mac or windows.

As a side note, my usb doesn't boot anymore after installing the default environment image. Hopefully I can fix the env parameters with netconsole when I get some free time. I saw another thread where the user had the same problem, so hopefully I can fix it using information there before my TTL usb cable comes.

Thanks for your help again.

Hi again.

I just bought a second pogo e02. I am trying to install the newest update uboot again and wanted to make sure my bad eraseblock is not within the first 1M of my NAND. Here is my output from dmesg.

[root@alarm ~]# dmesg | grep -i 'bad'
[    3.137387] Scanning device for bad blocks
[    3.157177] Bad eraseblock 206 at 0x0000019c0000
[    3.169361] Bad eraseblock 306 at 0x000002640000
[    3.177605] Bad eraseblock 354 at 0x000002c40000
[    3.185098] Bad eraseblock 392 at 0x000003100000
[    3.236921] Bad eraseblock 1015 at 0x000007ee0000

Also how do I interpret this information for future reference? Can you tell me at least what to google, I'm not sure how to make it a specific question google understands.. It gives me a bunch of search results about fixing a bad eraseblock and the like.

Thank you.

hachigo,

The info can be found in my thread about how to backup and restore NAND (it's in my signature):
http://forum.doozan.com/read.php?3,16789,16789#msg-16789

Specific explanation:

NAND block is 128K, so the 1st 1M of NAND contains block 0 to block 7. You bad block starts at 206, therefore they are way out of 1M.

If you convert 19c0000 hex into decimal you get 27000832 or roughly 27M

Thank you all. I had no idea. I am really just starting to delve into this computer stuff coming from a bioscience background, it's a bit of a learning curve.

Cool! have you heard of neural networks? would be cool to play with it on these plugs :) (the low power cost of these plugs would make it ideal to try)
