January 8, 20251 yr I built Armbian Edge from source (bookworm, server, no gui) and have no video via HDMI. Being a new build, networking is not set up and so I cannot SSH in to troubleshoot. I reverted to a stable Armbian build on another SD, upgraded that kernel to Edge, and lost video output. This one already has networking set up, I can SSH in, but I don't know what to look for in order to get my monitor working. Goal being, figure out what needs changed, and change it in the build process for a new image. I appreciate any pointers.
January 9, 20251 yr it may be in one/some of the patches, there is a huge thread about it where development originally started. probably to look in there to see if the patch can be found and applied to edge, at least locally the search box on top of forum probably could help
January 9, 20251 yr Can you try building from NickA's Armbian repo? https://forum.armbian.com/topic/29794-how-to-install-armbian-in-h618/page/17/#findComment-205764 I also lost HDMI video when I compiled official main armbian on my own... but I don't keep track which Linux version gave me the problem (I am working with SPI LCDs). When I tried NickA's branch, I got HDMI video.
January 11, 20251 yr The official armbian build hasn't patched HDMI in kernel's 6.10 and above. It's a 1000 lines of source that needs to be edited to apply cleanly. Not sure if there are other patches needed. kernel 6.7 was the last kernel version to use the patch. https://github.com/armbian/build/blob/main/patch/kernel/archive/sunxi-6.7/patches.armbian/drivers-hack-for-h616-hdmi-video-output.patch Most of the patches I use are from warpme's miniarch kernel build. I had to remove a few megous patches so warpme's patches would apply cleanly.
January 12, 20251 yr oh and get a usb-uart cable and work from the 'debug' (3 pin serial) port, that is an absolute necessity to mess with network configs https://www.aliexpress.com/w/wholesale-usb-uart-3.3v.html https://www.aliexpress.com/w/wholesale-usb%25252duart.html https://www.aliexpress.com/w/wholesale-usb-uart-ch340.html get those that is 3.3v or with a switch or jumper that you can toggle to 3.3v outputs, 5v is probably unsafe to put on the allwinner chip. I configured my that way from the serial console so that WiFi and ethernet sits on a bridge practically as my little desktop WiFi AP. --- but that HDMI patch is truly valuable
January 13, 20251 yr Author Thanks all - I've had to put this project on hold due to life events... I'll post results when I pick it back up.
