What you are trying to do is best achieved through DT overlays. Check the Armbian documentation about "DT Overlays", and also see if there is already an overlay that does what you want.

 

BTW, before asking for further help, make sure you provide the necessary information, according to forum rules, like the output of "sudo armbianmonitor -u"

Hi,

I’m using a nanopi neo3 board,  5.10.19-rockchip64, I’m trying to use i2s with a capture codec. I tried to change dts lines: “dma-names = "tx", "rx";”  “rockchip,capture-channels = <0x02>;” in i2s@ff010000 node both with armbian-config and also changing rk3328-nanopi-neo3-rev02.dtb file. After the reboot in /sys/firmware/devicetree/base/i2s@ff010000 there is still the old value dma-names = "tx\0"rx"; and there isn’t the capture-channels line.

I aim to enable capture audio with I2S input pin  using a bidirectional codec. Any suggestion is very welcome.
