Re: HowTo: openWrt on OXNAS boxes - 2 years ago
bodhi, sorry, but that does not make too much sense to me and I cannot really see the added value in this. In my eyes, the instructions are consistent and do make sense as they are. Also, it is steps 5 and 7 where we have a difference to the Kirkwood instructions, so I believe it is at these points where the issues should be mentioned.

bodhi, the first post is definitely updated: Edited 3 time(s). Last edit at 08/15/2022 01:44PM by chessplayer. Do you need to refresh the page, maybe? Cheers, chessplayerby chessplayer - Rescue System
Re: HowTo: openWrt on OXNAS boxes - 2 years ago
bodhi, since I had not touched my Pogoplug Pro for a while, I tried the first post on it and, as expected, got as far as we had gotten on the classic before. So then I looked at your proposed tests again and decided to modify them a bit, not quite knowing whether that would be what you really needed, but at least it got me some more info. In principle, the idea was to leave the mtdparts definiby chessplayer - Rescue System

Re: HowTo: openWrt on OXNAS boxes - 2 years ago
bodhi, thanks, I am beginning to understand that and I will update my Kirkwood HowTo tomorrow. Also, I will update the first post here to reflect what we worked out so far. As always, thanks for the consideration. Cheers, chessplayerby chessplayer - Rescue System

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 ...).

David, thanks. I probably use JTAG the wrong way, was aiming for the serial connection and kwboot (I am not an electronics person - otherwise I would, obviously, have a soldering iron ;-) ). Attached please find my current state of affairs. Now I will continue on the other end with a Nokia CA-42, with which I can connect individual wires. Hoping for the best ...

Re: uEnv.txt not read from boot device - 2 years ago
Hi bodhi, yes, I am aware of this. The problem is, however, that this is somewhat arbitrary and I wanted to be able to set up some kind of fileserver with hotplug capabilities, which I can also easily reboot, so that solution would not be practical. But putting the command into the standard bootcmd solved the issue for me, so all is well. Cheers, chessplayerby chessplayer - uBoot
uEnv.txt not read from boot device - 2 years ago
Hi, I just wanted to report an issue I just had on a Pogo E02 concerning uEnv.txt. I wanted to use the file to use systemd and it worked about three or four times. However, since what I am testing is to have the box act as a file server in the Windows network with automount of the non-boot attached devices, I have more than one USB drive attached.
