In DA_09361-002, it mentions that file “Jetson_Nano_customer_pinmux_release.xlsm” is required to be obtained to customize pinmux.
From download center, I can only obtain NV_Jetson_Nano_Module_Pinux_Config_Template.xlsm and NV_Jetson_Nano_DeveloperKit_Users_Pinux_Configuration.xlsm. Which one should I use to customize pinmux?
For devkit, there are two ways to configure the pinmux
The spreadsheet
The jetson-IO GUI tool.
However, the capability of each method is same. You could only changes those pins in spreadsheet. Unlike production module case, devkit version only has fewer pin to configure.
Does spreadsheet refer to NV_Jetson_Nano_DeveloperKit_Users_Pinmux_Configuration.xlsm ?
Correct.
Do you mean it is recommended to use production module instead of SOM from devkit, if we use a customized carrier board?
Yes, in fact, all the documents referring to hardware design is based on production module instead of devkit. If you want to make own custom carrier board, then you need to use the production module.
