Supply the following if possible:
- Device problem occurs on
Lamobo-R1 BananaPI Router
- Software versions of OpenWrt/LEDE release, packages, etc.
OpenWRT Snapshots (Imagebuilder) sometime after r12688-46d0ce19f1
- Steps to reproduce
Write any recent image to SD card, it boots but networking does not work.
Hello,
I'm doing regular updates with imagebuilder (about once per week) for Lamobo-R1. Some time after r12688-46d0ce19f1 the networking configuration broke.
I'm assuming the cause is kernel 5.4, because my last working image is from 2020-03-22 and it stopped working the week after, around 2020-03-29.
As far as I can tell the problem lies in the switch configuration: The switch is not found, the bootlog of kernel 5.4 contains no reference to "b53".

I'm attaching screenlogs of both old and new kernel boot and the corresponding device tree files (taken from the sdcard).
Please advise, thank you.
