generating dtsi file

[Ray9090]

Hi developers,

Though it is not directly connected with the meta-tegra layer, I would like to ask, as my full project is based on the Ycto tool now.
I am working with the Jetson Orin Nano custom carrier board with 4 GB SOM. For the custom board, we got an updated XLMs file where I generate pinmux, padvoltage, and GPIO DTSI file, and apply it to my image. Till now, everything was working.

Recently, I got an 8 GB SOM to test with this custom board. Default dtsi files are working, but when I am trying to apply the 4 GB version's dtsi file, the flash is failing. Specifically, pinmix dtsi (gpio is calling from here) is the main reason.

I have attached the XLSM file. Why is it failing?

I suggest you do a diff between the default dtsi and this one you've generated, and compare it between the 8gb default and 8gb generated ones. If you can report that here we might be able to help you. I'm assuming you've double checked all the assignments in your project and the correct files are getting picked up.

My custom gpio (generated from XLMS) and defsult gpio has some good difference. After I copied the missing pin and it is working. But these pin data does not needed for 4gb SOM. Where can I find these PIn details so that I can make decission.

The pins are all listed in that spreadsheet. My suggestion for you is to take parts of the default assignments and try them methodically, eliminating ones you don't need until you have the one or the few that you do. Other than that, you can look up the list in the spreadsheet and see if anything seems suspicious. Further inquiries about what the SOM really needs are probably best directed at the NVIDIA help forums.
