Hi,
I have a Respeaker 2-mic HAT with a WM8960 on it.
From what I can tell, it seems like it needs an I2S and an I2C interface.
There’s a DTS overlay for the Raspberry Pi and someone else has made one for the Rock Pi.
I’d quite like to make an overlay for the Radxa Zero — supposedly it supports I2S (or at least, it’s listed as having one I2S interface where I bought it.
However, I can’t find:
- any details about the I2S support, including its pinout on the GPIO header (this could be an obvious show stopper if the pins don’t match)
- any overlays that use I2S already
- any symbols in the device tree that look related e.g.
i2s1- a few things talk about audio but I imagine they’re probably just about HDMI audio — not that I understand them, I’m afraid
For context, some interesting bits of the device tree (obtained with dtc -I fs /sys/firmware/devicetree/base -O dts) seem to be:
