I managed to get the SPI to work. It is tested with the Minimal/IOT images with Armbian Linux v6.6 from the build date of end of January. I tried to copy the .dtbo files ( from above) to the following location: -/boot/dtb-6.6.72-current-sunxi64/allwinner/overlay The details can be found in the guide made by adif. 1. ls /dev > there is no spi 2. go to armbian-config What is spi* in orange pi zero3 ls /dev gpio readall 4. copy the .dtbo files ( from forum) to the following location -/boot/dtb-6.6.72-current-sunxi64/allwinner/overlay reboot gpio readall

>I think you only need spidev turned on in armbian-config This is what I did first, but could not find any ( in the /dev ) spi device. This triggered my to start searching for a solution and as far as I understand from this thread, there is a misconfiguration in the standard image. This is from the armbian website of the orange pi zero 3: Do you expect that in an image with an build Date of Jan 16, 2025 these fixes to get SPI to work are included? >I don't know why you copied a dtbo to /usr/lib/linux-image... Because I have very very basic understanding of the device tree. My thinking was, I do a sudo find -name *.dtbo -printf "%c %p\n" And see where the original files are ( that need to be changed). As I did not know what file are used during boot, I changed them both of them. I am still not really sure if you can replace these files on the sdcard and expect that they are used during boot. Is my expectation correct that I can just replace them on the sdcard and reboot, or do I need to rebuild and kernel/image ? What shows up in ls /dev/spi* ? /$ sudo ls /dev/spi* ls: cannot access '/dev/spi*': No such file or directory adif did get it to work and you can see that pin 24 if configured different. $ gpio readall +------+-----+----------+--------+---+ H616 +---+--------+----------+-----+------+ | GPIO | wPi | Name | Mode | V | Physical | V | Mode | Name | wPi | GPIO | +------+-----+----------+--------+---+----++----+---+--------+----------+-----+------+ | | | 3.3V | | | 1 || 2 | | | 5V | | | | 229 | 0 | SDA.3 | OFF | 0 | 3 || 4 | | | 5V | | | | 228 | 1 | SCL.3 | OFF | 0 | 5 || 6 | | | GND | | | | 73 | 2 | PC9 | ALT6 | 1 | 7 || 8 | 0 | OFF | TXD.5 | 3 | 226 | | | | GND | | | 9 || 10 | 0 | OFF | RXD.5 | 4 | 227 | | 70 | 5 | PC6 | ALT5 | 0 | 11 || 12 | 0 | OFF | PC11 | 6 | 75 | | 69 | 7 | PC5 | ALT5 | 0 | 13 || 14 | | | GND | | | | 72 | 8 | PC8 | OFF | 0 | 15 || 16 | 0 | OFF | PC15 | 9 | 79 | | | | 3.3V | | | 17 || 18 | 0 | OFF | PC14 | 10 | 78 | | 231 | 11 | MOSI.1 | OFF | 0 | 19 || 20 | | | GND | | | | 232 | 12 | MISO.1 | OFF | 0 | 21 || 22 | 0 | OFF | PC7 | 13 | 71 | | 230 | 14 | SCLK.1 | OFF | 0 | 23 || 24 | 0 | OFF | CE.1 | 15 | 233 | | | | GND | | | 25 || 26 | 0 | OFF | PC10 | 16 | 74 | | 65 | 17 | PC1 | OFF | 0 | 27 || 28 | 0 | ALT2 | PWM3 | 21 | 224 | | 272 | 18 | PI16 | ALT2 | 0 | 29 || 30 | 0 | ALT2 | PWM4 | 22 | 225 | | 262 | 19 | PI6 | OFF | 0 | 31 || 32 | | | | | | | 234 | 20 | PH10 | OFF | 0 | 33 || 34 | | | | | | +------+-----+----------+--------+---+----++----+---+--------+----------+-----+------+ | GPIO | wPi | Name | Mode | V | Physical | V | Mode | Name | wPi | GPIO | +------+-----+----------+--------+---+ H616 +---+--------+----------+-----+------+ Any tips that I can try ?

I am trying to get the SPI working on my orange-pi-zero3 (h618) to enable input shaping for my 3d printer. Hope I can get some pointers to get the SPI to work. Installed the following: Minimal/IOT images with Armbian Linux v6.6 Build Date: Jan 16, 2025 kernel: Linux 3dprinter 6.6.72-current-sunxi64 #1 SMP Fri Jan 17 12:36:27 UTC 2025 aarch64 GNU/Linux I tried to copy the .dtbo files ( from above) to the following location: -/boot/dtb-6.6.72-current-sunxi64/allwinner/overlay -/usr/lib/linux-image-6.6.72-current-sunxi64/allwinner/overlay -reboot ran armbian-config and enabled system->kernel->Manage device tree overlays->enabled sun50i-h616-spidev1_1 (nothing else) But I was unable to see a working spi port.
