Thanks.. I was going over this forum and found you saying there is a work a round for bad block in mtd0. I have bad address 0x0. What can I do? Is it ok to go ahead with "Bad eraseblock 571 at 0x000004760000" root@new-host-3:/# flash_erase /dev/mtd0 0 4 Erasing 128 Kibyte @ 60000 -- 100 % complete root@new-host-3:/# nandwrite /dev/mtd0 uboot.2016.05-tld-1.pogo_v4.mtd0.kwb Wby Chuck99 - uBoot
Is there a way to dump a directory tree so I can find where files are? How to download from Dropbox with Debian.by Chuck99 - uBoot
Now to get my V4-A3 working. Mobile is booting without error and no use of kwboot. Thank you. I would like to backup this USB hard drive. OK to plug into ubuntu and create a restore file?by Chuck99 - uBoot
how do you install the linux-tools from dropbox? 1RdYW8S. Or did I download it wrong? install is going good on mobile device but V4-A3 has problems noted above.by Chuck99 - uBoot
V4-A1 was after mtd0 nand erase and it had been used at least twice before. That was address 0x0. Now I get a report of one I the high end of the V4-A3 model. I don't have current log. It may not be a problem. I am going to get with the new Uboot now. Booting with kwboot is not hard to do but it will be nice when Debian loads directly. Thanks again. I started the uboot procedure.

Is that where the bad bit table is kept for nand ? Seems bad bits are popping up on 2 plugs now. These chips don't appear to be very reliable. I wonder if the write timing is too fast for them?by Chuck99 - uBoot
Where do you find this in writing? The -on, the -nf. Documentation seems so hard to find. Just for fun I tried loading Archlinux using their web site. Cut & paste and double checked each line. Found a typo and fixed it. Install went perfect. Except for last part. Downloading and installing new Uboot. Went error free but had to use kwboot to bring it half way alive. Tried vinnymac.org aby Chuck99 - uBoot
I have a question about mtd0-mtd4 sizes. In your download of pogo v4 originals why are mtd3 and mtd4 to large for the space allocated? I.e. Mtd3 is suppose to be starting at 0x800000 and is 0x800000 in size. The mtd3 file is 8.2 in size. Is not the entire file loaded into the nand? Do you know of any write up on the design of the Pogoplug v4? May be schematics. Thank you, Chuckby Chuck99 - uBoot
I can get the nandwrite tools downloaded to Ubuntu but when I log into Debian and get past the certificate problem I end up with one file. 1RdYW8S. What is that? How do I get the tools to Debian Pogoplug?by Chuck99 - uBoot
Please point me to the correct Uboot procedure. I don't want to mess this up. I did backup the Debian to Ubuntu with Disk create image and restored to another USB stick. Worked fine with kwboot. Debian now works pretty good with all the up grades and up dates. Eventually I want to install Samba for a NAS. I now have a mobile and a V4-A3 running Debian. Just need to get them to boot withoutby Chuck99 - uBoot
I'm afraid you are talking over my level. The uImage and env are from the result of the compile. Where do you copy it to on the USB stick? I'm thought I had to compile the uImage on the Pogoplug. The Pogoplug I thought was bricked is ok with kwboot again but has bad block at address 0000000 in nand. Any way to fix bbt? I can not nandwrite over it.

Here is the printenv file. what uboot can I use to get rid of the kwboot startup as a temp measure.by Chuck99 - uBoot
I got kwboot going again. I am going to install stereo phone jack on side. Stop wiggling wires and breaking them. have current dmesg attached. I believe printenv is good too. I need to set MAC address and cesvcid too. Any way to skip doing kwboot to get debian running would be nice as a temporary measure. Is there a remount command in debian? Thanks, Chuck99by Chuck99 - uBoot
Having trouble with USB to Serial converter. It has been flakey. Caused non boot of kwboot sometimes. I am going to work on hardware awhile. Thanks for help. I will let you know. Chuckby Chuck99 - uBoot
Did kwboot as usual. Stop at PPV4> prompt. Did copy paste this: setenv set_bootargs_usb 'setenv bootargs console=$console root=$usb_root rootdelay=$rootdelay rootfstype=ext3 $mtdparts' boot no errors. also did a saveenv. Since uboot was running in RAM I suppose that did not make any difference?? Is that a bad idea? Anyway sda1 is still read only.by Chuck99 - uBoot
Sounds good, thank you!by Chuck99 - uBoot
No, if you look at top of attachment you will see I was logged into root@debian:/boot#. I was going to say that may be the case sometimes. It is confusing. If you would tell me in your replies it would help. I am slowly learning. Which uboot should I use to replace one in Pogoplug? Do I have to compile one first?by Chuck99 - uBoot

running sudo gtkterm with Ubuntu trying to cp -a uImage.orig uImage and cp -a zImage-4.4.0-kirkwood-tld-1 zImage.fdt it says "read-only file system". tried chown and chmod. what now?by Chuck99 - uBoot
cp -a uImage.orig uImage cp: cannot create regular file 'uImage':Read-only file system. I assume this means I need to make uImage r/w but I forgot the command. Would it be ok to update uboot so I don't have to boot with kwboot to get Debian loaded.by Chuck99 - uBoot
Nice to have SSH! I think this text file is bad. .odt file should be good.by Chuck99 - uBoot
I have now booted Debian from USB. I had to first run kwboot with your .kwb file. Now what? Will it load without kwboot now or do I need to change mtd's? I have left it alone now. Shall I put in your Uboot next?by Chuck99 - uBoot
I think I am done with Debian on USB do I have to do the Linux compile next or do I need that?by Chuck99 - uBoot
Yes, I know about Pogoplug guys. They are really ripping people off but so far I have 3 accounts that are old enough that they are leaving active without cloud and no monthly fee as before. I only use them for picture backups etc. from iPad & iPhones. Your are correct. I did do most of the Debian on USB memory. Now I just need to know what to do with it.

The V4-A1 will not kwboot not. So I set it aside for awhile. The V4-A3 now connects to Pogoplug.com but can't find andy memory. Says it is off line. I think I have a mix of things running. It does not have SSH but serial still works and I can get a # cursor so something is working. I have attached log and ls of /sbin. Linux is working I presume to some extent. I am going to work on the Deby Chuck99 - uBoot
These things do strange stuff. Now kwboot stopped working after last attempt to load mtd4 but now I get a CE>> prompt everytime. What is difference between PPV4>> and CE>> prompt? I see I can not start usb for one thing.by Chuck99 - uBoot

How to you "Please reboot the target" without power cycling the Pogoplug?by Chuck99 - uBoot
I will definitely give it a try. I was thinking why doesn't kwboot loop looking for activity from serial interface? Does the Pogoplug not send anything until it receives a nak or something? You see many techniques using kwboot. What exactly is the correct way. Once I see any reply from Pogoplug I know I have it made. Just a pain to keep cycling power to plug. What is best to use for a leaby Chuck99 - uBoot
Followed instructions with no errors. Mtd0 went clean. Would not work. Had to use kwboot to re access. After loading mtd1 same thing. Loaded mtd2 now have not got kwboot to work again.
