Rock64 Audio DAC add-on board ethernet port problem [SOLVED]

Recommended Posts

Hello,

the Rock64 SBC can receive an add-on board with audio ports and an additional ethernet port. I have used it a lot before, with Debian Stretch. With the armbian image it does not work. The reason is simple, this board must be activated by a script which is missing. Ayufan has added a set of scripts in /usr/local/sbin, but they are not present in this build. They can be found here :

https://github.com/ayufan-rock64/linux-package/blob/master/root/usr/local/sbin/enable_dtoverlay

Then run the necessary command :

enable_dtoverlay eth1 ethernet@ff550000 okay

and the card is present in ifconfig. Once given an iP address, it works perfectly.

 

Nevertheless, the log indicates a conflct with the ic2 interface.

Nevertheless, the ethernet port is working. Is this a false alarm ? The Rock64 has two GPIO connectors, and the ethernet port is on the second. But the ic2 should be on the first. Whatever the reason, the port works fine.
