Keyboard not working on Radxa Zero #3

Closed ih8ms closed 1 year ago

ih8ms commented 1 year ago

I have a keyboard connected to I2C bus 3 (on Radxa Zero physical GPIO pins 3 and 5, I2C_EE_M3_SDA and I2C_EE_M3_SCL).

The keyboard isn't working. It looks like the driver was loaded OK, but I don't get any (input) events from the keyboard.

Got it, it works wit the following settings:

irq-gpio = <&gpio 451 2>;
interrupts = <3 2>;
