Unfortunately Dockstar does not find the "user" environment.
The very small "default" environment is used.
I have fixed the MAC and IP adress to the former values.
Perhaps I do not use the correct location to burn to

nand write 0 uboot-env.img 0xa0000 oob_softecc_kwLet me take a quick look at the mainline source code (your u-boot is straight from mainline). My version of u-boot do not use 0xa0000. The mainline one probably don't use that either.

Mainline u-boot uses 0x80000.
But your u-boot is OK, now. so it might not use the same location.
Don't worry about the envs, you can always set them to anything after booting with serial console.

Perhaps it might be helpful, to provide a Text file in Format of uboot command line interface, that can be transferred using the "send file" option provided by the serial terminal program.
But I failed to convert the more complex environment lines to u-boot commands
especially entering the bootcmd via "setenv" seems to be more than removing the "=" and adding "setenv" to the front ...

That's what my released u-boot does, using uEnv.txt (loading envs from disk drive).
https://forum.doozan.com/read.php?3,12381
uboot.2017.07-tld-1.dockstar.bodhi.tar
Without using that uEnv.txt capability (mainline u-boot does not have this), you can also use u-boot script loading. However, that will take some little works to prepare, too.

C. Add uEnv.txt to /boot directory (Optional)
To adjust the default envs to your specific configuration, and not having to permanently alter u-boot envs NAND. Create a text file in /boot directory with the content in the format that u-boot envs are listed.
Examples:
The example below only to demonstrate the syntax in uEnv.txt (they might or might not apply to your current settings):
- Load appropriate DTB file for the kernel to run GoFlex Net box.
- Use SD card, USB and SATA for booting. The kernel and rootfs search order is as they are appeared on the list: mmc, usb, ide.
- Define that there are 8 storage devices (i.e. disk partitions).
cat /boot/uEnv.txt
dtb_file=/boot/dts/kirkwood-goflexnet.dtb
devices=mmc usb ide
disks=0 1 2 3 4 5 6 7
Without using that uEnv.txt capability (mainline u-boot does not have this), you can also use u-boot script loading. However, that will take some little works to prepare, too.

Single Quote... Thanks for that hint. I will give it a try after work ...
An editable Text file has the advantage that it is quite easy to make individual changes e. g. IP and MAC settings per device, and feed them (after loading a common "base" Uboot Image per JTAG) without knowledge about the correct physical adress location of environment inside Flash ROM through serial line without any need of network connection and attached storage, TFTP server etc.

We had this capability for many years here :) usually it is much better to put it in a storage drive or the NAND rootfs partition. Why? because it can be used to tailor your environment without having a serial connection permanently attached.

In my understanding that can be achieved by asserting "saveenv" after loading the environment variables line-by-line with "setenv".
The situation now is, that there is a "tail" of environment variables at the end of the u-boot image. (I assume thats the reason, that the image is slighty larger than 512 kByte...)
The environment there is much shorter than the one in the separate image.
If I make uboot start from a flash only filled with the u-boot image itself no crc error is reported. The only problem is the quite short set of environment variables.
If I use JTAG debugger to clear the flash region 0x80000 size 0x20000 and write the separate *.environment to that location. u-boot regrets to load the environment and loads integrated default values ...
So it seem, that I have no way to puzzle together the last environment-image and u-boot image itself into the flash.

Sure. Those are the envs you are happy with (them after loading from a text file such as uEnv.txt, or type in explicitly at the prompt).
The text file uEnv.txt is meant to be a way to change envs without interact with serial console during boot (automatically load and imported). This file is to be resided on the rootfs /boot folder.
So uEnv.txt serves both purposes: During testing or inital setting (your situation), and later in normal operation to "tweak" the system behavior each time it's booting.

That is because you are not supposed to write that text file *.environment directly to flash. It has to be an image (with checksum) such as
See the installation instruction in my u-boot release thread for hints how to do what you want. The envs location might be different, but the idea is the same.

That is because you are not supposed to write that text file *.environment directly to flash. It has to be an image (with checksum) such as

Uhh, I think, I must look after that. I am quite sure, that I have done so, but i have copied it to the working directory of OpenOCD renaming it to a convenient short name, so it is not clear from file name, how it was named originally. Perhaps I have worked on the wrong file all the time ....
It will be best to do a complete refresh of all the files from downloaded tar-Archives ... they are definitvely untouched ...

hi @joerg_999
i'm trying to unbrick my stora ms2110 via jtag (rasp PI1)/openocd
so i soldered jtag, and seems ok using openocd :
i can't halt it :/ and without it i can't acces nand...
without knowing what i'm doing i use this conf (pogo):
perhaps some address are not good for the stora.
thx for your help.

AloneTrio,
A few observations.
The config file that you use is for Pogo E02. The Stora has the same SoC, but there are differences.
So different u-boot image, envs image, and training sequence are needed.
1. This uboot.kwb should be the new Stora u-boot. Get the uboot.2017.07-tld-1.netgear_ms2110.mtd0.kwb from my release thread: https://forum.doozan.com/read.php?3,12381
2. This uboot-env.bin should be the default envs uboot.2016.05-tld-1.environment.img (also from https://forum.doozan.com/read.php?3,12381)
3. Here is the tricky part. The training sequence that joerg has is for Pogo E02.
You need to look at the Stora training sequence from my latest u-boot source for the Stora (from the GitHub) and incorporate the Stora parameters:
https://github.com/mibodhi/u-boot-kirkwood/blob/2017.07-kirkwood-tld-1/board/Marvell/netgear_ms2110/kwbimage.cfg
Once you get this JTAG working, your config will be the Stora config that will come in handy for future Stora unbricking.

@ alonetrio
i am on a businesstrip this days, but for the first i would compair the start sequences for both sbc´s like bodhi said:
Startsequence Marvell/Sheevaplug (Pogo E02) and Startsequence Marvell/Netgear ms2110 and check the difference.
PS: the -work-area-phys 0x10000000 \ is wrong in your config, it should be 0x100000 !!!!

I cannot get my Pogoplug E02 to reflash the u-Boot binary, or to load u-Boot into RAM and execute it.
I am running openocd on a Raspberry PI 3B. This is openocd v 0.10.
Can anybody figure what is wrong? I have a feeling that some part opf the setup is not right, because I cannot even load uboot and execute it.

Which uboot.kwb were you using? you could try uboot.2017.07-tld-1.pogo_e02.mtd0.kwb. See if you will get different result.

I exactly followed the instructions in the first post.
softlinked: uboot.kwb -> uboot.2017.07-tld-1.pogo_e02.mtd0.kwb
I switched the JTAG & serial over to another pogoplug E02 that is good. Didn't try flashing, because I'm scared to corrupt this one.
So I tried downloading the uboot.kwb and running it, according to the proc pogo_load_uboot in
/usr/share/openocd/scripts/board/pogo.cfg.
It loads and verifies, but it will not run. It just comes back and gives me another prompt. Uboot does not start, the LED does not go on and nothing comes out on the serial console. Is the resume going to the right address? Does something in the boot ROM not like something it sees in the kwb that is in memory?
I will try seeing if I can copy the (good) uboot that is flashed in the NVRAM and get that one to start up. The first post in this thread is somewhat old, I wonder if something changed between then and now.

Ray,
Flash u-boot image to the bricked Pogo. You got nothing to lose with that unit.
Update:
I see. There was a timeout error.

hello rayvt
maybe the post1 starttime is old but its not outdated and works until now.
first, care about this: the important thing is the status "ARM state
second,
you cant go further and erase or flash if you dont get the right output here:
also both uboot and uboot-envs are up to date:
i tried this procedure on several Pogos and always with success.

Well, I'm going crazy here.
After trying (and failing) to write a good uboot into NAND, I switched the JTAG cable over to another Pogoplue E02 that works. I wanted to find a procedure which would load a Linux system so I could try to use nandwrite to flash the uboot.
First step was to use JTAG to load a uboot and execute it.
As I mentioned earlier, the current uboot (uboot.2017.07-tld-1.pogo_e02.mtd0.kwb) would load but would not run.
After the "resume 0x800200", nothing happened. No led, no serial console output.
Eventually I decided to try loading the old old original Pogoplug uboot.
load_image uboot.mtd0.dockstar.original.kwb 0x800000
resume 0x800200
WORKED!! I got console access. Could even load the rescue system from mtdN. Very limited uboot, though. It could not successfully run the rescue system, which complained it couldn't get a valid machid.
So then I moved up to:
load_image uboot.mtd0.pinkpogo.jeff-2010-10-23.kwb 0x800000
resume 0x800200
That also worked.
So then I moved up to:
load_image uboot.mtd0.pinkpogo.davygravy-2012-02-20.kwb 0x800000
resume 0x800200
No good. Nothing happened. No led, no serial console output. Obviously something changed in the uboot between the 2010 version and the 2012 version. Because none of the versions after Jeff's 2010 version will run when loaded by the JTAG.
By this time, my wife was asking why I was spending several days trying to unbrick a $10 computer. Wanted to know why I just didn't use one of the Raspberry PI Zero-W's that we bought for $3.14 last year at the Microcenter sale. Good question.
So anyway, I then switched the JTAG cable back to the bricked Pogoplug. Nada. I think that this unit had a hardware failure. The JTAG on it used to work but now it does not work anymore.

rayvt, your wife is right, but i spent the time to learn more about how to handle things like bootloader, envs and repair SBCs and routers with broken uboot. First i started to repair broken Pogos with Buspirate (very old, from 2012 and slow but works also fine) and later i tried to use the common Raspi erverybody have laying around.
The result is this thread.
But like bodhi noticed, your timout is strange, maybe you can try another adapter speed and/or try more often if the first time fails :
use 2000 kHz instead of 200 khz
in my case it worked, but i had some reports from people where it didnt work with the higher speed.
One point at the end: use short cables to connect! max 30cm its about 11inch
good luck!
