Which excel is suitable for customize pinmux configuration?

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?

File “NV_Jetson_Nano_Module_Pinux_Config_Template.xlsm” seems to be more relevant.

If you are using production module(no sdcard slot), then please use module sheet.

Could NV_Jetson_Nano_Module_Pinux_Config_Template.xlsm be used for SOM with sd card? I notice the value of Boot Device can be EMMC or QSPI.

No, I don’t think it is good to use it for sdcard SOM. The boot device option there seems no function.

I see. I only have SoM with sdcard (A02?). Is there a recommended way to customize pinmux? Or is it necessary to buy a new production SoM?

Hi fdtsaid,

For devkit, there are two ways to configure the pinmux

  1. The spreadsheet
  2. 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?

Do you mean it is recommended to use production module instead of SOM from devkit, if we use a customized carrier board?

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.

Thanks you. I can’t find jetson nano production module on amazon. What keyword should be used to search this product?

Finally I find out a provider that sell module with EMMC and has no sdcard.
Is production module compatible with P3449 A02 carrier board?

I confirmed that production module only compatible with devkit B01 carrier board.

Yes, please check the FAB ID on the back of your module. If it is a B01 module, then you cannot use it on a A02 carrier board.
