[WrongWorld]

Thanks a lot for all the info, I think they will be very useful to anybody wanting to add the second Ethernet port to Rock64.

I have followed another approach: since I was not able to find locally any 1.8V voltage regulator, I resorted to an LM317L for which I calculated the needed resistors for outputting the needed 1.8V: once I will have the circuit properly working, I will be back to this at a later time, publishing also the relevant schema.

My problem is now in enabling the eth1 device. I am currently using DietPi 6.19.7 with ayufan kernel 4.4.132-1075-rockchip-ayufan-ga83beded8524. I have tried the command

Code:

sudo enable_dtoverlay eth1 ethernet@ff550000 okay

but I obtain invariably the following output, and the eth1 port is not made available:

Code:

Applying...
/dts-v1/;
/ {
       fragment@0 {
               target-path = "/ethernet@ff550000";
               __overlay__ {
                       status="okay";
               };
       };
};
Warning (unit_address_vs_reg): Node /fragment@0 has a unit name, but no reg property
unapplied <<---- !!!

I tried to do the same with another device, for instance i2c0, and it works perfectly. Am I using the wrong kernel??? What am I missing?
