RK3566 Kernel with NPU support?
If you are on a relatively recent kernel, the kernel probably already has support, but the default DTB has it disabled. This is from a bookworm nightly build for a radxa zero 3 ~$ grep rknpu /usr/lib/modules/6.1.115-vendor-rk35xx/modules.builtin kernel/drivers/rknpu/rknpu.ko However, it's disabled in the DTB by default $ cat /sys/firmware/devicetree/base/npu@fde40000/status disabled For the board that I am using, the vendor publises a DTO source that enables it at https://github.com/radxa-pkg/radxa-overlays/blob/main/arch/arm64/boot/dts/rockchip/overlays/rk3568-npu-enable.dts Which works well with armbian-add-overlay. Though you may need to make a similar overlay for your DTB if it is different enough. Note that the NPU in the 3566 and 3568 are interoperable. -

Is Docker available?
Here some troubles are expected ... Can you try manual steps to install docker by follow: https://github.com/armbian/configng/blob/main/tools/modules/software/module_docker.sh#L26-L56 installing packages, adding to group, adding docker bridge. This might reveal more. BTW. My F3 died - waiting for replacement. -

Customboard with RK3566 flashed with OrangePi3B Armbian minnimal image, no more MaskMode in RKDevTool
Ok, I was able to boot on maskrom mode! I had to cut the bottom shield (it is soldered, but I'm not using lora anymore so I didn't care). Just cut the shield right beneath the eMMC chip, and you'll uncover some pads. Short-circuit the middle big one (clk) in the attached photo with any gnd point, and plug the thing. That made the magic for me. -

Orangepi Zero 2W wrong color display on MPI3501
I am glad you could do it with the orange pi zero 2w, because I also want to use a very small arm board I am having trouble with the red ili9488 red LCD's touch function, and if I keep having no results, I will replace with the waveshare LCD model (I wanted to have 4-inch LCD ) What armbian and linux version did you use? If you go to the latest linux, you may need to modify the DTS a little bit (modifications are in my ili9488 thread). Warning: I use a different driver (parameter "compatible") for DRM graphics, and different drivers might need different DTS lines. Always use a different microSD for experiments, so you don't mess with your working setup Does the orange pi zero 2w just need male pin headers on the 40-pin connector, and then plug the LCD on top? -

Orangepi Zero 2W wrong color display on MPI3501
Thank you so much for sharing me the thread, i finally make the screen true color follow dts of user wdr_s Here is my dts file The thing i change compare with dts in https://github.com/dev-null2019/orangepizero2w35tft : 1. spi-max-frequency from 48000000 to 16000000 (I think it due to speed of spi on the board) 2. And in init, i change both value of 0x1000036 0x48 I test on Debian Bookworm, Armbian it work ok Note that, with this device tree, i got reversed touch screen (up to down work ok, but left to right is reversed) so i need to change the calib matrix Here is the content of /usr/share/X11/xorg.conf.d/80-calibration.conf Once again, Thank you very much. I stuck in this problem 3 days, and try so many device tree, and try full supported os from orange pi but it not work, until follow your thread.
