I thought it was a good idea to use to change Arch Linux u-boot installer script based on Bodhi's instruction,
so I would be able to use the original linux system that included in my Pogoplug to flash the u-boot.
I didn't work, but somehow I could still boot into Arch Linux from usb drive.
I installed uboot-env and tried to figure out what happened.
It seems that anything after flashing the uboot.environment didn't stick,
So my next step was just to continue from "Adjust MTD parts".
Well that bricked my Pogoplug,
it doesn't boot not from usb and not from sd.
The funny thing is that now it does light up the green led, I've got now idea what it means.
Next step is to try and get serial working, my soldering skills are horrible.

dhead,
Arch Linux uBoot is a different version, so at this point, you can't use uboot-env tools, you would need to use blparam to change uBoot envs. The good sign is LED stays green, it likely means your uBoot is OK, just the envs are messed up so you can't start the kernel.
To avoid having to solder the serial pins, I've tried this once successfuly: Use 3 small pins (the type that was used in new shirt box) to push them in the solder buttons on the board for GND, TX, RX. Got them connect temporarily, I was able to connect the serial console and interrupt uBoot, just long enough to set up netconsole :) After that it was easy to change uBoot envs to boot Debian.

Thanks Bodhi,
I've got netconsole up, I use netcat for windows.
I flashed Davy's uBoot,
but after that I thought it be good idea trying the Arch Linux way of revert,
using fat32 usb drive with revert folder, I'm not sure if that made any changes.
Here's the output from netconsole
Here's my env print http://pastebin.com/8FenMybv
I'll try setting env arguments manually, .

Maybe the culprit is that my file system is ext3 and not ext2 ?
This is the output when trying to boot from sd
http://pastebin.com/sawmkDXy
This the output when trying to boot from usb
http://pastebin.com/NZtiQESf
It look like it booting to Arch Linux,
but I can't get access to the machine and it doesn't get ip from my dhcp,
so maybe it gets some errors later which I may need serial to diagnose.
I tried changing arcNumber to 2097 but that didn't helped, maybe also need to remove machid ?
I may add that before changing the env arguments I booted successfully to Arch Linux from usb with ext3 filesystem.
I'll try next ext2 filesystem.

Since your uBoot env for rootfs type is Ext2, it should boot Ext3 without problem (but the reverse is not true). Looks like the SD card was not found by uBoot, perhaps you need to repartition, reformat and put a new roofts on it. The USB drive seems to work, but I think the Arch kernel did not complete booting, so you never got to the point where dhcp is requesting ip from the router. I would do the same, puting a fresh Arch rootfs on it. Or you can put Davy's NSA320 rootfs on either the SD or USB and boot the box with it (this is what I would do but of course if you want to run Arch then it's not applicable).

Setting usb_rootfstype=ext3 fixed non booting from usb.
Now I'll try to boot from sd,
I used Win32 Disk Imager to copy my usb installation to the sd card, that didn't work.
I also tried manually creating ext3 partition and "cp -p -r" the content of the usb drive to the sd card, again this didn't work.
On both cases I'm getting the exact output as I attached before
http://pastebin.com/sawmkDXy
I'm guessing that maybe the fault in my uboot arguments.

A little "success" I found out that I can manually boot from sd on uboot but no automatically,
meaning I need to manually execute the command "boot", else the uboot don't find the sd card.
I'm not sure if that something I done.
Anyway it's only a partial success, after the uboot load the kernel it does not fully boot to linux,
maybe it's the same as the issue I had before with the usb drive
and need to set somewhere that the rootfstype is ext3.
I tried different approaches but with no success.

Success, finally I can boot from sd.
Here's my custom settings (with the usb_rootfstype= ext3 from before)
Still something is wrong with uboot, it seems that on the first "mmc init" it doesn't find the sd card, so I need to run it again, maybe it can be fixed by adding a delay (probably on the source of the uboot, not as an argument).

I am not sure what you're trying to do? are you booting with Davy's uBoot?
To boot back to the PogoV4 stock OS, Arch Linux ARM's uBoot has these envs set up to boot back to stock:
load_nand=nboot 0x800000 0 0x200000
load_nand2=nboot 0x800000 0 0x500000
boot=bootm 0x800000
boot_nand=run load_nand boot || run load_nand2 boot
mtdparts=mtdparts=orion_nand:2M(u-boot),3M(uImage),3M(uImage2),8M(failsafe),112M(root)
So mtd1 and mtd2 are at 0x200000 and 0x500000, respectively. With Davy's uBoot, this still applies because only mtd0 was modified.
BTW, winestock has a nice Pogoplug V4 revert script (written for Arch Linux, but could be adapted to Debian easily):

@Lucky^Luke,
Are you sure your device is bricked ?
if you followed the instruction it's really hard to brick the device, you will need to flash the wrong uboot, flash uboot to the wrong address or delete some addresses which the uboot resides.
Maybe you only need to set the correct uboot params ? you could do this with serial connection (need a bit of soldering and usb-ttl adapter (not 12v logic).
Did you followed Bodhi's instructions you might could get the netconsole up and wouldn't need serial.
If your device is really bricked (meaning corrupt uboot) you can try booting from serial, I've manage to ressurect a bricked pogoplug mobile with this method, it takes a few tries though, I've found that using shorter leads helps.
http://forum.doozan.com/read.php?3,7852
And don't forget to flash the uboot after successfuly booting from serial, I've managed to do that.

Did you sucessfully set up netconsole on PPv4?
I'm keep trying but no success :(

Thanks ;)
I'm using Pogoplug Mobile. I just go through ArchLinux's steps to install Alarm and before reboot, I add netconsole parameters using blparam command.
I'll post specific command that I used for netconsole setup when I get home.
I just wonder if it is possible to use netconsole in PPv4 or Mobile, because I read some post said I cannot use it.
By the way, I don't have serial cable.

@halogen,
After you've installed Arch, your uBoot is off a version that does not have netconsole support. So you blparam env settings for that will be ignored. If this is what you have then there is no need to see the log.
If you have installed Davy's version of uBoot then you do have netconsole. The uBoot in this thread is Davy's version. For a more detailed instruction, see the following thread:
http://forum.doozan.com/read.php?2,11663
Note of caution, without serial console, you will need to be extra careful.

I'm about to install uboot and have a quick late minute question. When I looked at flashing NAND instruction, it found something not in common. (I marked in red.)
When I look at the arm linux script - http://archlinuxarm.org/os/ppv4/ppv4-install.sh
flash_erase /dev/mtd0 0x100000 4
nandwrite -p -s 0x100000 /dev/mtd0 /tmp/uboot.bin
and davygravy's instruction - http://forum.doozan.com/read.php?3,7477,page=1
flash_erase /dev/mtd0 0 4
nandwrite /dev/mtd0 /tmp/uboot.nandpogoV4-MMC-mtdparts-noSATA.kwb
one of other instruction
flash_erase /dev/mtd0 0x180000 4
nandwrite -p -s 0x180000 /dev/mtd0 uboot-arc.bin
Why do they have different memory address(?) to erase? Can anyone explain to me?
Thank you. :)

nandwrite -p -s 0x180000 /dev/mtd0 uboot-arc.bin
Why do they have different memory address(?) to erase? Can anyone explain to me?
Thank you. :)

uBoot is on mtd0. The difference in instructions is because they are different versions of uBoot builds (the 1st one is Arch Linux ARM version of uBoot). If you run this command:
cat /proc/mtd
you will see the list of mtd partitions that your current installation has. And when look at your dmesg, the mtdparts are listed there.
So the bottom line is if you want install Davy's version, these commands will flash that uBoot image to mtd0:
flash_erase /dev/mtd0 0 4
nandwrite /dev/mtd0 /tmp/uboot.nandpogoV4-MMC-mtdparts-noSATA.kwb
And of course if you flash other versions, the appropriate instruction applies.
cat /proc/mtd
you will see the list of mtd partitions that your current installation has. And when look at your dmesg, the mtdparts are listed there.

@bodhi
First I initially successed to boot from SD card with your instruction. But after changing macadress env, it won't start anymore. Since the greed LED light up, I guess my PPMobile just mess up with network setting.
Now I have to figure out how to make serial connector. :p
By the way, netconsole isn't not working either. I once successed from my other E02 so I don't think I missed setenv.
Anyways wish me luck. ;) Thanks.
PS. Is there way I can set up IP address manually from ArchLinux SD? By mounting SD from other linux machine and changing some network settings??

Yes, that's how you do it. Just mount it on another box and change IP to some static number. Arch has moved on to systemd so you will need to get the instruction at Arch site as where the IP is defined (in the old days, you'd change it in /etc/rc.conf).

Thanks bodhi and dhead,
I'm out of luck this time. I did change /etc/network.d/wired-eth0 as static, however, it seems my bricked PPMobile stocked somewhere before completely booting.
Anyways, I just order serial-USB adapter to bring my PPMobile alive. I will keep up posting my status. Thanks guys. :)

I successfully attached serial and got ready for netconsole as well.
Even though I see the green light, I'm still experiencing network problem connecting over ssh. It seems like both static and dhcp doesn't work properly.
It's very similar to john3votas' thread on Booting DHCP issues OR sosuke's thread on PogoPlug Mobile SD Boot Troubles
Now I'm researching possible causes that I made a mistake. wish me luck.
