I mean using
(which was calculated from the OpenWrt MTD-layout) instead of this
(OpenWrt original) in fw_env.config

P.S.: Awake - not fully anymore, so anything else will have to happen tomorrow ...

I mean using
/dev/mtd1 0xc0000 0x20000 0x20000
(which was calculated from the OpenWrt MTD-layout) instead of this
/dev/mtd2 0x0 0x20000 0x20000

Actually, I would like to come back to this with a question: Should there not be a modified MTD-layout here as well after passing it in the uBoot-env? The debian MTD-layout is also not influenced by the setting in the uBoot-env, it seems to me...
As I said before: confused!

chessplayer,
What you see in Debian is a better implementation. We have new u-boot defines the envs location at 1MB in flash. The DTS has mtd0 as writeable. And the Debian kernel was configured to accept the bootargs (command line arguments). So everything works.
On OpenWrt side, it's the other way around. The envs are at a different location. The MTDs are protected by read-only property in the DTS. And the OPenWrt kernel was not configured to accept the command line arguments. So we cannot change the envs at all.
Note that the only hurdle here is the command line arguments. If the OpenWrt kernel had this configured in, then we would be able to pass mtdparts into the kernel and everything will fall into place. But we don't want to recompile the kernel, or try to marry the Debian DTB file to OpenWrt kernel. Sysupgrade will wipe that out each time, and things will be confusing for the users.
So that where your confusion was.
====
OK, so now you guys have found a work around to specify the location of the envs from my u-boot. And can read them. It's half of the solution. Let me write in the next post the other half. To complete a relatively cookie cutter process.

This is my current thinking. A bit of experiement needed to script the u-boot envs during boot so that it can attach and read the ubi rootfs and load a text file from it.
It sounds overkilled, but this is probably the only way, given the limitation of OpenWrt put on us. And we dont want to recompile its kernel.
==========
Reference to the u-boot installation instruction: 2015.10 U-Boot for Pogoplug V3 (OXNAS OX820).
To be able to "set" envs in OpenWrt and let the new u-boot read it, we need to use uEnv.txt capability. This was mentioned in the installation Section A.
==========
Testing steps
1. Log in to OpenWrt and create uEnv.txt with the initial content as below
Use nano to edit this file (to ensure it is a proper text file)
Add this single line
2. Reboot
2.1 Attach ubi partition
(TBD)
2.2 List the OpenWrt directory to find the exact location of uEnv.txt.
(TBD) The UBIFS volume is probably the first letter, and eventually down that path, we'll find uEnv.txt.
2.3 Setup u-boot env to load it.
(TBD) The current bootcmd_uenv scans and loads uEnv.txt from disk storage. So we need to adjust this to load from the UBIFS volume.
2.4 Test print

Quote
A. How to use the uEnv.txt script (Optional)
This uEnv.txt script can be used to further customizing u-boot envs without saving to NAND or to boot with a completely different set of u-boot envs.
Create a text file in /boot directory with the content in the format that u-boot envs are listed.
==========
Testing steps
1. Log in to OpenWrt and create uEnv.txt with the initial content as below
mkdir -p /boot cd /boot
Use nano to edit this file (to ensure it is a proper text file)
nano uEnv.txt
Add this single line
loaded_envs=See_uEnv.txt_from_rootfsExit and save the file.
2. Reboot

chessplayer,
Sure,
1. Make sure the uEnv.txt will survive a sysupgrade. Most important to find out first! if it does not, then that will need to be a caveat for users to save the file and restore.
2. Boot with serial/neconsole. Interrupt u-boot and
Mount it
List files in /boot

Other thought: we can also file a "bug" report at OpenWrt site to request for this OXNAS kernel processes the bootargs passed into by u-boot :)

I am pretty sure that nothing survives a sysupgrade except for files in /etc/config (see the output of 'sysupgrade -v' in David's post further up). So, here is my test, which I performed with an addition. Booted into OpenWrt and then:
Additionally:
Now the sysupgrade (went back to the latest stable version)
As you can see (green line), uEnv.txt in /etc/config can be expected to survive (and forget about the red line - the sysupgrade works). Let's test that:
Conclusion: The /boot-directory did not survive. Thus, if the file absolutely has to be in /boot, it should be symlinked. However, since the uBoot-env will have to be customized anyway, why not just read it from /etc/config right away for the OpenWrt boot?

First of all, I think this has to start with:
So, this is as far as I got, since I am obviously too stupid to specify the volume name:
This did not help either (as you can see at the bottom of the above code).
Please advise!

Conclusion: The /boot-directory did not survive. Thus, if the file absolutely has to be in /boot, it should be symlinked. However, since the uBoot-env will have to be customized anyway, why not just read it from /etc/config right away for the OpenWrt boot?
No it does not have to be in /boot. /etc/config is fine!

No, seems like this is the one combination I haven't tried ;-)
Anyway, it looks like the last sysupgrade broke something, since the box is not picked up anymore by netconsole during boot and it does not boot OpenWrt anymore ... I am currently trying to boot your debian from stick and hope for the best - if it does not work, I might have to try reinstalling the rescue system, but then I do not know how to update the envs ...
Just realized that this won't work either, since I cannot install OpenWrt without access to nc ..
Will get back once this is sorted out but it may take some time, since I will be out of town tomorrow!

Arghhh :)
Let's regroup. I think we are trying too much to get around this limitation without examining the flash structure created by OpenWrt installation and sysupgrade.
For now it's a caveat in the installation: that you can only read from the envs inside Openwrt, but can only update it in serial/net console.
I have to boot up my Pogo V3 (it's on the shelf). I need to build new Debian stable kernel anyway. So will see what I will find out.

Curious as to why you can't update envs in OpenWrt? The uboot-env partition is not set read-only.
This should allow editing the environment after installing the uboot-envtools package and creating the appropriate config file.

You should read the whole thread!
I will boot up my Pogo V3 and see for myself. But it does make sense to me from what I've seen in this thread that OpenWrt can not write to it currenly.

Hi chessplayer,
I've not been able to boot up my Pogo V3 yet. But I've looked at my old notes. Wow 5,6 years ago :) I created a Kirkwood rescue system but never release it.
If you see the volume rootfs_data from the layout, try mounting it. It seems to be OpenWrt standard naming convetion used also in Kirkwood boards.
That should be the overlay part of the system (formatted in ubifs). The rootfs volume cannot be mounted, since it is a squashfs. I don't believe this u-boot even knows squash.

Hi bodhi,
thanks for looking into this further. I'll report here what I found so far and will stop at the question as to how to proceed. What you should know beforehand is that I
What you will see from the logs to follow is that the OpenWrt in RAM cannot read your uBoot-env, which kind of makes me wonder how it is that it can nevertheless boot your system from stick ... (for the real conclusion scroll down to the P.S.) But, in particular, I am reluctant to install OpenWrt in this situation, since I do not want to brick the box again (-> I am a moron!)
0. in uBoot
So, spot on, bodhi, the rootfs_data volume can be ubifsmounted, but, apparently, the OpenWrt installation in NAND did not survive the brick status ...
So, next step: try installing it to NAND again:
1. Boot OpenWrt uImage to RAM
So, all is well. Let's see what we get when we log in.
2. inside OpenWrt in RAM
So, OpenWrt no cannot read the uBoot-env as it was able to before!
Therefore, I believe what I should do now is:
Would you agree?
Cheers,
chessplayer
P.S.: I thought this would be it BUT THE ABOVE PROCEDURE BRICKED THE BOX AGAIN - that is apparently what OpenWrt not being able to find the uBoot-env when booted into RAM was trying to tell me and I, of course, wasn't listening ... Off to fetch the CA-42 again, since netconsole is, for obvious reasons, not available anymore either - no, hold on, uEnv.txt does the trick, as we have learned ... :-)
EDIT: So, after the rant, I must make it clear that the "brick" is just a semi-brick, since using uEnv.txt I can boot debian, but, obviously, uBoot has to be re-installed and also OpenWrt. This is the current state of affairs and I am ready for the next tests ...

Hi chessplayer,
No need to reinstall u-boot.
You've missed a recommended step in the installation. Joerg have mentioned this (now that I reread his post and tried it myself on the NSA310S).
So I think the reason for unsuccesful reinstall is sysupgrade behavior when the partition is not empty.
I have not modified your Kirkwood installation post to mention this, but you should after confirmation.

bodhi,
thanks for the hint. However, I am unclear on some points:
Re-reading my Kirkwood-HowTo, I actually found that @daviddyer mentioned this early on, but, as you can see from my answer, I never had this issue on the Kirkwoods (and I can now even add the NSA320 and NSA325 to the list ...). However, it now seems to come to bite me that I did not just add it at the time, since it looks like the OXNAS' really want to have this.
But, what do you mean by 'confirmation'? How would I test, whether this is necessary? Or, better yet, where exactly would you add this command? It is my understanding, that step 4. (when booting OpenWrt into RAM) should be:
(the nand.erase should be on the data-partion with this mtdparts-definition, shouldn't it?
Then, sysupgrade should proceed (but it does so also without it, as long as I re-install your uBoot - so which positive effect is it you are expecting? I do not quite understand - sorry about being a noob and doing trial and error here). Will report on the further tests soon.
Cheers,
chessplayer
EDIT: I think the question is whether you assume the mtdparts definition we should be using for the tests or the one we still have in the uBoot-env. For the tests we do:

So, I did all of these again and got the same results as above:
Then, I got (which seems like relevant info):
Also, I can now only boot into debian again with the uEnv.txt as mentioned (so, no more netconsole). When I do that, I get:
So, it seems to me that I WILL have to re-install uBoot at this point, won't I (at least if I want to use netconsole - with the serial cable, the situation might be different). I will go ahead and do this later and then I will see what happened to OpenWrt ...

No need to reinstall uboot. You can either reflash the env image, and adjust it.
Or just copy the entire default envs into uEnv.txt. And boot into serial/net consile and populate the envs, and save thems.

Ok, so now I re-installed uBoot and installed OpenWrt the following way:
In OpenWrt in RAM I did the usual, but then tried the ubifs instead of the squashfs
This led to (in uBoot):
So, I do not even get as far as I used to ... BUT:
So, OpenWrt is still there in NAND and I can boot from it - thanks for the nand.erase hint again! I will now try the sysupgrade with the squashfs instead of the ubifs and see if I can get as far as before in uBoot.

Ok, that's what you mean, I do not have to re-install uBoot itself, just the envs - of course! Thanks!

After the sysupgrade with the squasfs instead of the ubifs, the result is exactly the same:
So, the nand.erase was necessary also to realize that what we thought we saw before were really artefacts ...

Yes, that seems to be the case. Because I don't think you would want sysupgrade to format NAND partition at all (it would wipe out current user setting). It only update the existing partition using ubifs.
And with NAND you always need to erase the sectors before writing the inital image. After that, ubifs takes care of the managing of bad sectors, and also wear leveling.

Yes.
Note that Kirkwood or OXNAS NAND, it is the same. You always want to erase NAND before initial image is written. If it works without erasing then you just got lucky :)
And then if you reinstall, then you need to treat it like the 1st time. Erase NAND partition again.

chessplayer,
I'm reading the instruction in the 1st post. As I go, I will make a different post for each suggestion.
I think realy we don't want even mention the issue about envs not writable here. As long as the ubi partition appears correctly in OpenWrt layout, the installation will proceed OK. And then when you talk about fw_env.config later, you would elaborate.

5. Log in to OpenWrt
Find the IP address of your box and ssh into it (user root without password). The following step is absolutely crucial but does not yet quite work the way it should.
