Built latest image for a Rock 3c based device and am having an issue with ethernet connectivity. Boots fine. Wifi works well and it seems functional other than Eth connectivity. 

My old DTB (from 4.19) will not boot , using a rock3c DTB instead to get a 90% functional device

Showing the following for ethernet 

dmesg | grep eth

4.19 kernel boots fine with Eth connectivity with latest u-boot, so this appears to be a kernel issue. 

Any idea where i should look in the dtb? I am basically blindly looking into it right now and could use some pointers. I've been looking around these forums for the last hour or so and really don't see anything related directly to my board/issue

Attached the old (4.19) based dtb with working ethernet and current (no ethernet)

Yeah. Messed with those options to match the original. Tried changing 1 line at a time, etc ,etc.


Pretty much changed that node as many ways as I could, doesn't seem to be the case. I'm assuming it's somewhere else in the dts file

Update

i created a patch to add +CONFIG_PHY_MOTORCOMM=y to the uboot defconfig since the chip is a Motorcomm YT8512C. Changed things up a little.

Will continue to work on, although any insight would be great. could use a nudge

I've now resigned myself to the fact that using Raxda's SBCs requires external adapters, they are not able to provide even a minimal working system, as their latest Debian image demonstrates: https://github.com/radxa-build/rock-3c/releases/tag/b43.

 

So yours don't work either, or am I doing something wrong?
