Yeah, I already used the image from armbian website. Already when it was only in beta (support) it worked fine for my needs, and I was able to decompile the dtb file, configure the i2c port, recompile, reboot and it worked fine. Even with 400kHz clockrate.
But the same thing does not work for SPI ports.
As SPI1 is used for the flash, I always tried SPI2.
But there is no /dev/spi* and all my attempts wasn’t successful.
