Hello,
I compared the devkit module and the production module with your command. Please comment when you confirm the comparison.
Thank you.
Hello!
In the above bit 0 is set and so this means that the I2S4 function is not selected. I am not sure exactly what version of the Nano you have (A02 or B00), but the DTSI generated by the spreadsheet should yield changes such as the following …

Hello,
I did exactly as I was told to change the excel file.
Is there an additional work to modify the dtsi file after the excel file is changed?
Can I simply edit the dtsi file as you tell me?
Thank you.
Hello,
I have modified the files in the following path to: Is that right?

The dtsi file from the excel file was as follows.

Thank you.
Should ^M be appended?
Thank you.
Hello,
In the process of copying the dtb file, I copied the command as the following as the guide says, but should it be 0002?
Thank you.

Hello!
The pinmux settings now look good, but it appears that the soundcard is no longer registered. What does the following show …
$ cat /proc/asound/cards
$ dmesg

Hello!
No that is just an editor artefact.

Hello!
I would compare the original dtb with that you have generated. You can use fdtdump to extract the contents of the DTB file.

I think it’s been a lot thanks to your answers thank you.
Can you show me an example?
I don’t know what to compare with.

Hello,
Originally, pinmux should be set up normally with only the dtsi file created from the excel file without manually modifying the dtsi file like this?
Thank you.[quote=“jonathanh, post:43, topic:155840”]

In the dtsi file I created in the excel file,
in dap4_din_pj5 {}
nvidia,tristate = <TEGRA_PIN_DISABLE>
It was supposed to be.
What you showed with DIFF
nvidia,tristate = <TEGRA_PIN_ENABLE>
is.
Could you cross-check once more?
Hello,
I am using b00 and attach dtsi file created from excel file.
Thank you.
Hello!
So this would indicate that both soundcards are present. So does speaker-test still fail? Maybe try …
$ alsactl init tegrasndt210ref
$ speaker-test -D hw:tegrasndt210ref,0 -c 2 -r 48000 -F S32_LE -t sine -f 500

To be honest, this is not critical. Either setting should work. For the DIN, which is only an input, we do not need to enable the output driver and hence I set tristate to ENABLE.

Hello,
this result is result of devkit module,

Hello!
Can you provide the dmesg output for this board?
