Good news: this is merged in Armbian main now, many thanks to @c0rnelius and @Igor for reviewing this. So no more need to grab my fork, just clone Armbian/build:main. I was able to build and quick-test orangepirv2/edge-kernel and this looks fine including Wifi. There are of course unsolved quirks currently. With edge-kernel, Wayland does not work, we need to use Xorg. And with the current bcmdhd Wifi driver, AP mode is not possible. This is caused by outdated file in armbian-firmware for bcmdhd and may be the same on OrangePi5. There is a mechanism to load a different fw_bcm43456c5_ag.bin (the one downloadable from github/xunlong seems to work). LG // Sven-Ola

is there a guide for booting opi5 from nvme that works with Armbian 26.2.1 -noble or trixie? The standard way via armbian-install seems broken

I just tried LibreELEC 13 testing builds as they are also running kernel 6.18. Audio seems to work there and I can hear all channels or speakers. I guess LibreELEC includes HDMI audio support patches for RK3588/S and NanoPi R6S that Armbian hasn’t incorporated yet ? The ALSA rockchip-i2s-tdm driver needs to support more than 8 TDM slots or support the HDMI multi-TDM mapping for 5.1 / 7.1. LibreELEC patches

As it turned out, Orange Pi does not support Power Delivery Negotiations and requires a "dumb" power supply providing 5V 4A. My power supply delivered 2A and then went into protection mode; the board itself had nothing to do with it

Make sure you have ili9486.ko in your ko module folder: modinfo ili9486 Can you use the DTS that I published in: https://forum.armbian.com/topic/47971-driving-the-ili9488-lcd-40-inch-cheap-chinese-clone/#findComment-208446 But change the "compatible" line with waveshare,rpi-lcd-35 , Delete the stuff under the "compatible" line, until the "}vsync-len = <0>;", and replace it with what you had in your DTS. Change these lines, if they are different: spi-max-frequency = <24000000>; rotate = <270>; bgr; fps = <30>; buswidth = <8>; regwidth = <16>; Reference: https://github.com/raspberrypi/linux/blob/rpi-6.12.y/arch/arm/boot/dts/overlays/piscreen-overlay.dts
