Actually, hope is not all lost. The image downloaded for the 4c from Armbian. Has the sources set to beta. So, I changed them and was able to install armbian-config. Although it isn't officially supported on the version I'm using. It does the job. Disabled kernel and firmware updating. Also, add Radxa's Bookworm repo. Ran a upgrade and all is well. Should last me a few years. Until the day I decide I want to throw a bunch of my time at an other SBC.

@John Taylor I finally had some time to test this today and it is working fine for me. I built a fresh image on an ubuntu laptop, copied the image to a SD card, it mounted fine on ubuntu, where I edited the extlinux.conf file and then used the SD card to boot on an amlogic based TV box. You mention etcher as your sd card tool. Etcher in recent versions (recent being the last two years or so) is known to have problems. It is no longer recommended for use with Armbian images. I have noticed that in particular if Etcher is burning a compressed image it doesn't work for me. But I have had some success if the image is uncompressed first. But others have reported that it fails in general.

First of all, thank you to @Hqnicolas and all the members for this great effort. Just bought an H96 rk3566, having this hardware configuration: BOARD LABEL: HCY-RK3566-1X32-V20 2023-01-13 SOC RK3566 PMIC RK809-5 LAN RTL8211F DISPLAY FD6551 WIFI AIC8800D40 eMMC H26M74002HMR - SK Hynix eMMC 5.1 NAND Flash 64Gb. It seems to be a mix of the other versions described in this topic, although very close to the one of @WINEDS (thanks for the hints). Everything seems to work so far.

My solution is to compile the image like this: ./compile.sh INSTALL_HEADERS=yes Then scp the driver on the machine, and execute echo "obj-m += panel-mtf0397swi.o" > Makefile make -C /lib/modules/`uname -r`/build M=$PWD cp panel-mtf0397swi.ko /lib/modules/$(uname -r)/kernel/drivers/gpu/drm/panel/ depmod -a

Hi @eselarm, thanks for the detailed response. I've checked my boot.cmd and boot.scr is ancient ( from Aug 2023 ). I'm going to try to set the variables beforehand, as I see in the output they are blank ( devtype, devnum, prefix ). When I succeed I guess the next step will be to set these variables in U-Boot, but nowadays there's no gpt partition table in SPI with the uboot_env, so I guess will need to figure it out later ( via env or find the boot.scr in the NVMe ), first I want to try to boot from NVMe manually. Thanks again
