Also reviewing if openwrt has any useful patches https://github.com/openwrt/openwrt/pull/3101/files

You can use frank-w kernel from https://github.com/frank-w/BPI-Router-Linux/ branch 5.15-main or 6.1-main

[martinl]

Thanks, I'll take a look at 6.1-main

Also, adding second gmac without multicpu DSA for wan interface looks interesting for router usecase:

You can prepare patches for PR

I can help with testing in the second part of March

Looks like frank-w has already figured out adding the second gmac frank-w/BPI-Router-Linux@ddcb74f

I'm currently working on building bpi-r2 edge u-boot v2023.01 and 6.2 kernel config based on openSUSE tumbleweed jeos (that also supports many other arm sbc-s along with bpi-r2 and is currently using 6.2.1 mainline with some arm relevant patches)

Can this be pushed forward?

I'll try to pick this up after I move to my new apartment and free up my r2. Seems not before 2024Q1
