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](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](https://community.blokas.io/t/pisound-on-tinker-board/1015)).

I also read the relevant .dts files in raspberry pi ([here](https://github.com/raspberrypi/linux/blob/rpi-4.14.y/arch/arm/boot/dts/bcm2710-rpi-3-b-plus.dts)) and tinkerboard ([here](https://github.com/TinkerBoard/debian_kernel/blob/develop/arch/arm/boot/dts/rk3288-miniarm.dts)) 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)](https://pastebin.com/YJkTe3nF), 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](https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%2520Linux%2520Driver%2520Package%2520Development%2520Guide%2Fhw_setup_jetson_io.html%23)), I was hopeful but it doesn’t seem flexible enough to support Pisound easily.

I also started [a thread](https://devtalk.nvidia.com/default/topic/1068512/jetson-nano/pisound-on-jetson-nano/post/5414443/) 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?

Thank you for looking into this, I’ve posted a reply on Nvidia forums.
