I2S MEMS Microphone not working with Jetson Orin Nano Devkit

Robotics & Edge Computing Jetson & Embedded Systems Jetson Orin Nano

I’ve been trying to connect the Adafruit SPH0645 microphone to my Jetson Orin Nano devkit, but it seems like my system doesn’t recognize that anything’s connected to it. For context, I have:

Reconfigured the 40pin header to I2S with jetson-io.py

Connected the mic to the following pins:
3V: 1
GND: 6
BCLK: 12
DOUT: 38
LCRL: 35
SEL: none

The results of arecord -l are:

It just keeps going like that until device 19

When I use arecord -D hw:APE,0 -c 2 -r 48000 -f S32_LE -d 10 test.wav the output is

Recording WAVE 'test.wav' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo
arecord: pcm_read:2221: read error: Input/output error

I could really use some help figuring out what the heck is going on, I’ve even tested every connection with a multimeter just in case and everything looked normal, so it’s probably not a physical issue. A million thanks if anyone can help me out here!

Hi Sobeyisabella,
Could you provide the entire list of amixer commands configured before running the capture usecase with arecord?.

Is this what you wanted me to do? I tried to do all the amixer commands in the link you sent, but some of them didn’t seem to work.

The link provided just have examples. Before I could suggest you with right amixer controls. Could you tell us which Jetpack version used on your target.

7

Could you try with below commands after rebooting.
$ amixer -c APE cset name=“I2S2 Mux” “ADMAIF1”
$ amixer -c APE cset name=“ADMAIF1 Mux” “I2S2”
$ amixer -c APE cset name=“I2S2 codec frame mode” “dsp-a”
$ arecord -D hw:APE,0 -r 16000 -c 1 -f S16_LE out.wav

Please provide the below dump from target

amixer -c APE contents > log.txt

log.txt (307.2 KB)

13

Thanks!. I could see I2S2 are connected to ADMAIF1 Mux, ADMAIF2 Mux and I2S1 Mux. This is not right config.

Please reboot the device and make sure I2S2 path is connected to single ADMAIF Mux. Attach the log as mentioned above after reboot if still issue exists

14

Sorry, but I’m not quite sure how to do that. Is it different from using jetson-io.py to reconfigure the pins?

15

jetson-io.py is just used to enable I2S pinmux on 40 pin header.

Could you provide the below dump after the target reboot. So I can provide you right commands to run

amixer -c APE contents > log.txt

16

log.txt (307.2 KB)

17

Assuming the latest dump after reboot, then there seems to be boot time amixer configs happening which needs fix.

Now you can try with the below commands

$ amixer -c APE cset name=“ADMAIF2 Mux” “None”

$ amixer -c APE cset name=“I2S1 Mux” “None”

$ amixer -c APE cset name=“I2S2 Mux” “ADMAIF1”
$ amixer -c APE cset name=“ADMAIF1 Mux” “I2S2”
$ amixer -c APE cset name=“I2S2 codec frame mode” “i2s”
$ arecord -D hw:APE,0 -r 16000 -c 2 -f S16_LE out.wav

18

I did all the commands then rebooted, this was the result of arecord -D hw:APE,0 -r 16000 -c 2 -f S16_LE out.wav

Recording WAVE 'out.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Stereo

>>I did all the commands then rebooted,

The commands provided should be run after rebooting the device. Please reconfirm as the above statement is confusing.

I did all commands after rebooting, here are the results:
