Thank you. I also can confirm this issue on Armbian 25.5.1 Bookworm, and that the suggest workaround works. For those interested, here is a more detailed explanation of what @Lars Christian Nygård said. Create a backup of original DTB. sudo cp /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dts /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts-orig.dts Decompile the DTB for the Orange Pi 3 LTS. sudo dtc -I dtb -O dts -o /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dts /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb Modify the decompiled DTS file according with your favorite editor, e.g. nano or vim. sudo nano /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dts Navigate to the "spi@5011000" section and modify it. Set "status" to "okay" and add the "spidev@0" section. spi@5011000 { compatible = "allwinner,sun50i-h6-spi\0allwinner,sun8i-h3-spi"; reg = <0x5011000 0x1000>; interrupts = <0x00 0x0b 0x04>; clocks = <0x06 0x53 0x06 0x51>; clock-names = "ahb\0mod"; dmas = <0x2e 0x17 0x2e 0x17>; dma-names = "rx\0tx"; pinctrl-names = "default"; pinctrl-0 = <0x31 0x32>; resets = <0x06 0x20>; status = "okay"; #address-cells = <0x01>; #size-cells = <0x00>; phandle = <0x78>; spidev@0 { compatible = "armbian,spi-dev"; reg = <0x00>; spi-max-frequency = <0xf4240>; }; }; Save and compile the modified DTS file. sudo dtc -I dts -O dtb /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dts -o /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb Remove any previously configured overlay for SPI using "armbian-config" or editing the "/boot/armbianEnv.txt" file directly. No further modifications are needed to load our new recompiled DTB, since we directly modified the base DTB. Reboot when done.
