New Pink Pogoplug B04 bricked

$this->bbcode_second_pass_quote('redsquare', '')$this->bbcode_second_pass_quote('timstegeman', 'O')h, i have made a backup of the original uboot on mtd0. Now we only need to find a way to restore this image.

I got a second one which runs the original Pogoplug Software. If you describe how to dump the bootloader I can do it and upload it somewhere.

I have it but I don’t have it on my public share. It will be there by tonight.

Great!, If it works, I'll post some details on how I got it back together. At the moment, It's not all that foolproof, and you'll need a serial cable and a SATA disk.

Ok, I've bundled up the entire mtd0, with and without oob (out of band data). It's 44MB compacted with tar cjvf (so use tar xjvf to extract).

Once it is extracted, and you have are booted into an ALARM OS, get the mtd-utils package and you should be able to flash_eraseall and then dd the non-oob. If that doesn't work we'll have to do it from uboot off the sata drive.

Look for oxnas-mtd0.tar.xz, and I apologize for the speed of my current internet connection.

This is not (Yet) a recovery mechanism, just an attempt to get to one.

So in order to get some sort of U-Boot running you need a SATA disk, create a partition on it (Just so an MBR is created). From there, extract the attached tarball, and edit the script to point to the correct drive you want to use. You'll need to change the kernel if you don't have PCI on your board.

Connect it up to the Pogoplug and you should see on the serial that the board now runs U-Boot and attempts to boot Linux from the HDD. I use the following U-Boot variables to boot into my setup:

$this->bbcode_second_pass_code('', '
setenv bootargs "root=/dev/sdb1 console=ttyS0,115200 rootwait mem=128M"
run select0 load1

bootm 60500000
')

The problem I'm having now is that I'm not able to successfully burn and run from flash. I get errors as in my previous post, I wonder if my NAND is bad? I think I've tried all combinations of flash_eraseall and nandwrite with both the OOB and non OOB.

OK! Good news!

I don't know where, but redsquare somehow got his hands on some of the "magic dust", it wasn't from me, but this is essentially a cleaned up version of the "magic dust" to make it boot from a HDD. I will use this on my toasted "ProDev" I mentioned in a previous post in an attempt to solve the issue of why it won't go to NAND right.

What this meands for PLX OXNAS 7820 boards:

Full SATA Boot.
Full Capability to change out the kernel
Full Changable Initrd's
UN-BRICK BAD FLASHED NANDS

Not-yet uboot
Not-yet "newer" kernels.

I just booted entirely off of SATA...
Needs some tweaking, but this appears to be viable.
