BUILD CUSTOM SDK

I found vccio6 on soquartz should be 3.3V not 1.8V. The summary page on page 3 of the schematic is wrong. On page 25 it can be seen clearly the chip's pin 27 is connected to vdd_h which sets 2.5V signalling (3.3V tolerant).

So I've changed vccio6 to 3.3V, but still Ethernet isn't working (only link state changes work).

Perhaps there are other differences.

Edit:

I've managed to get Ethernet working by copy/pasting the gmic1 sections from mainline dts files to the older kerneio-dm

 
Good nice to see you solve it with a hint


io-domains is almost the most important

and watch the pmic in quartz64-a it is rk817 on a quartz-b it is a rk809
