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. [ 0.000000] psci: probing for conduit method from DT.

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

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 [ 0.000000] psci: probing for conduit method from DT.

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) rk3566-box-current.dts rk3566-box-4.19.dts

Installed this on an old Heltec Helium miner Any idea how to enable SPI so spidev shows in /dev/?
