Getting Pisound to work on Jetson Nano

#1

Hi,

I’ve been looking into making Pisound work on Jetson Nano but I’m not very skilled for it and I come to ask some help.

I asked on github first (https://github.com/BlokasLabs/pisound/issues/11), understood that the kernel module won’t be the most problematic and that the main effort will be to write the correct dts overlay, as it was done for the tinkerboard S (see here).

I also read the relevant .dts files in raspberry pi (here) and tinkerboard (here) and try to make a general rule to write a dts overlay for the Jetson Nano.

I could generate the .dts file from the Jetson Nano (Here is a pastebin), I generated it like this, the kernel being downloaded from Jetpack.
dtc -I dtb -O dts -o - tegra210-p3448-0000-p3449-0000-a00.dtb
I think that’s correct, please correct me if not…

The new release of JetPack has a new tool to configure the GPIOs (docs here), I was hopeful but it doesn’t seem flexible enough to support Pisound easily.

I also started a thread in the nvidia dev forum to ask for guidance. It seems they are internally discussing about supporting Pisound by default, which would be great !

Would anyone be willing to help me on this?
