Using the I2S interface



I have a custom board where I need to use the I2S interface, namely I2S0 [193, 195, 197, 199].
I’m interested in activating this interface
Also, are there any examples of using this interface (activation and configuration) from Nvidia in C/C++?

You can use jetson-io to configure the I2S pins.
Suppose should be able find some relative topic by search in forum.


I have a problem with my jetson-io. I don’t have the “Configure 40-pin expansion connector” option, I only see the csi connector setting.

Looks like your Nano is emmc version that don’t support configure 40 pins by jetson-io. You may need to modify the device tree manually.

I just installed the SD card module and ran the command:

sudo /opt/nvidia/jetson-io/

but the program started and immediately closed
