NanoPi R2S Plus

It’s indeed weird: The kernel repo does contain device tree sources for a lot of NanoPi R2 revisions, but I cannot find any for R2S Plus in any branch either: kernel-rockchip/arch/arm64/boot/dts/rockchip at nanopi-r2-v6.1.y · friendlyarm/kernel-rockchip · GitHub

And there is no Linux 4.x branch for these.

Hello,

Okay, I see that. I informed the FriendlyElec engineer about it, and after my complaint, they updated the kernel repository for the R2S Plus.

how are you engaging with FriendlyElec ? i had posted on their forum about something last month and didn’t get any replies.

Hello,

Sorry for my bad english ,I didn’t want to complain, but rather to inform.

And i engaging with FriendlyElec on a Github Issue.

Great, many thanks. So this is the device tree for Linux 6.1: kernel-rockchip/arch/arm64/boot/dts/rockchip/rk3328-nanopi-r2-rev24.dts at 11a45048d424cc9b1b3b6508e089ca4ba56a83ff · friendlyarm/kernel-rockchip · GitHub

So who needs to do what to push this a little bit further along?
Something with the Armbian build?

Feels like I’m not super helpful on this build, but perhaps I can learn all the steps for the next one.

Does the R2S image actually boot into the kernel, or does it fail at the bootloader already? I wonder whether we’d only need the R2S Plus device tree built with the kernel, or a new U-Boot build as well.

Why not convert the freiendly-debian to dietpi? I have done on one this morning, and seems all running okay.

How is that friendly-debian → dietpi conversion working for you? @MichaIng had previously indicated that those were perhaps not the best starting point. But perhaps they can be used to pinpoint whatever needs to be done to make the armbian version work?

Working quite well, had to disable overlay filesystem though, otherwise the converter cannot find boot partition (cannot remember the exact message) and fails.
LANs got detected, CPU temp is working. Did not need anything else, so cannot comment on other things.

I was going through some SD cards and R2S and R2S Plus devices this last weekend and I think I found that I was able to get an RS2 Plus to boot up to a semi-working state with an SD card that I had used in a R2S with a usb wifi configured. wifi on the R2S Plus wasn’t working, but didn’t try to resolve yet. So when I have time I will try to revisit that path and see if I can get it fully working.
