[pcduino8 uno]

i'm using VERSION=22.11.0-trunk buster. I have made a discovery though, if i set my unifi switch port to 100m instead of 1000m it works fine.. So I'm guessing it's a timing issue, just not sure where to adjust that in the source.

Yes I am using debian but the kernel is built from kernel.org not debian, I have looked at patches but the ones I found for the pcduino8-uno are for 3.x kernel versions

I am new to arm devices. I'm trying to build a fully working armbian system for the pcduino8-uno which uses the Allwinner a83t/h8 soc.

I know these are not the best, but I got it from amazon for $18 and it runs home assistant very well.

I built a new u-boot which appears to initialize the hardware properly as it sees all the usb port as well as obtains an ip from my dhcp server.

Using sun8i-a83t-allwinner-h8homlet-v2 as my starting point.. I built a new kernel from 6.1.0-rc6. Everything seems to work properly except the ethernet controller.

I can use a usb ethernet dongle, but I would like to get the onboard working

Dmesg shows "

[    1.594628] dwmac-sun8i 1c30000.ethernet: IRQ eth_wake_irq not found

"

I'm assuming something is incorrect in the ethernet driver.

Any Ideas how to fix this ?

Thanks
