Debian on Synology DS211 (15 replies)

Hello,

I have this device:
DS211 Marvell Kirkwood 88F6282

Goal is to build latest u-boot and install Debian or OpenWRT.
Stock u-boot has no saveenv command, but I have also red in some forum posts that Synology messed up saving the env, and that would brick it.

1. How do I go about building DS211 device specific u-boot that I can flash
I was reading around the forum but have not found anything specific to DS211. So far I have managed to play with kwboot and boot via serial console uboot.2023.04-tld-1.nsa325.kwb, that is obviously meant for a different device, but it did boot. All other kwbs available in the forum wouldn't boot with kwboot.

2. OpenWRT has no mention of DS211, so I am not sure I can make it work

3. Debian has some mentions of DS210 and DS212 here: http://ftp.debian.org/debian/dists/bookworm/main/installer-armel/current/images/kirkwood/device-tree/
But not specifically DS211. I would hope that DS212 is supported that would be similar enough to work on DS211.

Here's the stock firmware via serial console:
