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.

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.

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.

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?

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.
