The rockchip-w1-gpios.dtbo overlay has it hard coded to GPIO1_A4, which is available on both RockPro64 and NanoPCT4, but unfortunately not availaible on RockPi4B ... For RockPi4B, you will have to either do yourself a custom build with a patch that change this pin, or decompile/edit/recompile de overlay itself.

I found descriptions to add dtparam=i2c_arm=on,i2c_baudrate=400000 to /boot/config.txt As Armbian hasn't this config file I tried to add the same line to /boot/armbianEnv.txt but it doesn't seem to have any effect. 0 Quote

For thus who try to C&P the above clock-frequency string: Attention it contains non-standard space chars after the number. So compiling to dtb fil fail with an error.
