Hello,
Looking at the excel, my chest feels stuffy and dizzy.
Is this part correct? To set it up like the following command you gave me
How to edit this part in Excel?
Thank you.
Hello!
Sorry about that. It is a bit complex. So you need to …
- Set column ‘AS’ to be the DAP4B signals
- Set solumn ‘AT’ to be bidirectional for FS and SCLK, input for DIN and output for DOUT
Then you should click the Generate DT button.
Regards,
Jon

Bidirectional?
Thank you.

Hello,
What is DAP4B signals in this excel sheet?
Mark it in Excel
Can you take a screenshot of the Excel screen you set?
Sorry to bother you.
Thank you.

Yes, that’s correct!

Hello!
Sorry I believe it is I2S4B. If you click on the cells in column AS then you should see the I2S4B signals as an option. So if you click on say “GPIO3.PJ05” you should see an option for I2S4B.

Hello!
Please see this guide. The following steps are necessary before running the apply_binaries.sh script …
$ tar xf ${L4T_RELEASE_PACKAGE}
$ cd Linux_for_Tegra/rootfs/
$ sudo tar xpf ../../${SAMPLE_FS_PACKAGE}
$ cd ..
$ sudo ./apply_binaries.sh
A description of what the above pacakges are can be found in the above guide.

Hello,
As you told me, I set up pinmux in the production module and flashed it.
The sound-test is executed as follows.
There is no sound when I put on the earphones.
I thought the sound came out when the speaker-test was run.
The sound came out from the devkit module set up using jetson-io.py.
What can I check?
Thank you.
Hello!
Compare the pinmux settings between the Nano modules (SD version and eMMC) by …

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.

In the process of copying the dtb file, I copied the command as the following as the guide says, but should it be 0002?
