Having trouble with my klipper accelerometer every time the dtb is upgraded during a update/upgrade. I made this patch to fix the spi@5011000 { ...} section: 831c831 < status = "disabled"; --- > status = "okay"; 834a835,840 > spidev@0 { > compatible = "armbian,spi-dev"; > reg = <0x00>; > spi-max-frequency = <0xf4240>; > }; > And then dtc -I dtb -O dts -o sun50i-h6-orangepi-3-lts.dts /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb patch -b sun50i-h6-orangepi-3-lts.dtso opi3lts-dtb.patch dtc -I dts -O dtb -o /boot/dtb/allwinner/sun50i-h6-orangepi-3-lts.dtb sun50i-h6-orangepi-3-lts.dts Not sure if this is a sane and safe way to do it, but it works for me at least. Hope it can find it's way in a sane form into a future release. Maybe it's better to do it in an overlay, rather than directly? opi3lts-dtb.patch

I updated my system and it broke again. Had some trouble getting it to work again. For some reason the DTS editor doesn't come up in armbian-config anymore(?). Anyway, it can be done from the console. I decompiled the sun501-h6-orangepi-3-lts.dtb, edited it and compiled it again. It worked as a charm. I noticed that the spi pins had changed to 0x31 and 0x32 and the spi@5011000 phandle was 0x78 instead of 0x7a. I only changed status to "okay" and added the spidev@0 {...} section. Then I removed the dtbo overlay. 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>; }; };
