Have tried several dtbs, not work. And find no way to change kernel version, only current and edge can be chosen.

@maka I just install wsl2 to compile image, I use ./compile.sh EXPERT="yes" find some rk3566 borad such as H96-tvbox-3566, the output image file is "Armbian-unofficial_24.8.0-trunk_H96-tvbox-3566_bookworm_current_6.6.44.img", seems kernel is 6.6.44. Anyway, I will try this image first.

@SteeMan I use rk3566-slzn.dtb right in this post. And use device-tree-compiler change one usb info from otg to host.

By the way. Is there any convenient way to modify file in SD card? After I burn image to SD card, my computer(Windows 11) cannot recognize it, I use another armbian machine modify the SD card currently. Can I use my Windows computer modify the file? I searched in search engine not find useful infomation.

@maka Thanks. I will try the images you mentioned.

@SteeMan I'm using ophub images, I thought both armbian images, I will try Armbian image. panther-x2 is also RK3566, in my opinion same CPU share same image just different DTBs. Thank you for giving me some initial understanding.

Cannot work. I use panther-x2 image and change /boot/armbianEnv.txt, "fdtfile=rockchip/rk3566-panther-x2.dtb" to "fdtfile=rockchip/rk3566-slzn.dtb". also paste rk3566-slzn.dtb to dtb folder, but black screen when power on. I try to build new image, but I cannot understand boot.cmd and boot.scr.

Now I find a project https://github.com/ophub/amlogic-s9xxx-armbian can build image. In its model_database.conf file, I find Rockchip RK3566 Family share one mainline uboot called u-boot.itb. And device-tree-compiler seems can modify .dtb file. I will build one image to test, but still doubt with how to enable multiboot.

how to use this dtb file？I only find a guide for amlogic, 1: burn the image to an SD card 2: modify /boot/extlinux/extlinux.conf to set dtb 3: copy the correct uboot for your box 4: enable multiboot on the box I don't konw if this same to Rockchip CPU, for step1 I cannot find the image named "Linux 6.1.43 Rk35xx..." in the capture. Then step 2, I see some modify in DTB, such as "Find the USB port list and change 1 port USB from OTG to HOST", but I open the .dtb file, it seems raw binary file, how can I read and save this file，some tools or rules？ And no idea for uboot and how to enable multiboot for this Tanix Tx66 TVbox. Thank you so much for any clarification you can provide！
