Can't get SPI interface

[Виктор Хомченко]

Hello everybody! I need help: I can't turn on the SPI interface in any way so that /dev/spidev0 or /dev/spidev1 appears. In armbian-config, there are generally only 7 lines in the hardware section, in which there is nothing interesting, an attempt to register spidev in armbianEnv.txt it also does not help, in dmesg and journalctl - silence... Where did the interface go?

I answer myself: the overlays are here: https://github.com/radxa/overlays/tree/main You need to take the desired overlay, compile it using dtc and put it in the /boot/dtb/rockchip/overlay folder. Next, turn on the overlay in armbian-config and voila

spidev1.0
