@qq20739111 Sorry, I forgot to update the kernel config. Ethernet should work now. @humanus "DP works without replugging"

Hi @qq20739111, In the log, DP looks fine to me, maybe you can try plug in / out a few times? The display is not that stable to be honest. As for the ethernet, I think @Nick A didn't update the config so the driver is still not built into the kernel (https://github.com/NickAlilovic/build/blob/Radxa-mainline-WIP-a7s/config/kernel/linux-sun60iw2-edge.config). You can build by yourself (just enable CONFIG_AW_STMMAC_ETH)

I'm trying to activate the UART9 overlay to enable an additional serial port. According to the Armbian documentation, I should create /boot/armbianEnv.txt and add overlays=uart9 to it. However, after multiple attempts, the serial boot log doesn't show any changes, as if the file isn't being read at all. Here's what I've tried so far: Created /boot/armbianEnv.txt with the following content: overlays=uart9 Tried different overlay_prefix settings (e.g., overlay_prefix=k1). Renamed the file to orangepiEnv.txt after seeing it referenced elsewhere. None of these changes seem to have any effect, the UART9 device doesn't appear in /dev/, and the boot log doesn't reflect the overlay being applied. Could someone point me in the right direction? What am I missing here? Once I get the UART9 overlay working, I'd also like to create a custom overlay to use a GPIO pin for PPS (Pulse Per Second) input. Any guidance on that would be greatly appreciated!

Hi @rm_, I tried my RV2 with current kernel and disabled bcmdhd. For reference, I have uploaded the image to https://privat-in.de under "Downloads". Prevented bcmdhd.ko from loading. There is no such load. I don't thing that waiting a couple of hours will change that. Also, I have zero IPI4 irqs, thus you may need to locate the interrupt source, e.g. with lspci and lsusb. Maybe you changed something in the kernel cfg, please compare attached cfg to your /proc/config.gz). HTH // Sven-Ola config.gz
