Hi All,
I was testing DMIC, but I got some error, first I flashed my AGX to Jetpack 4.5, after that I connected my MIC IC(MP34DT01-M-PDM MEMS microphone-Adafruit 3492), then I started the example from here, it worked, but when I enabled the SPI function by using Jetson-IO, DMIC did not work any more, no matter I disable the SPI function or reboot AGX.
This is my error log:
