Please check with Nvidia before using functions that end with a '*'?

Dear all,

In some Jetson carrier board designs and in the document Jetson_Xavier_NX_Pinmux_Configuration_Template_v1.06.xlsm there is a note:
"Please check with Nvidia before using functions that end with a ‘*’ "

So with all the signals with ‘*’, I have to check with Nvidia before?

In particular, I want to use the SPI0_CS0*, SPIO1_CS0*, and UART1_RTS*, UART1_CTS*.
What should I take note of these signals, please?

Best regards,
Kien

hello kiennus84,

may I know what’s the modification you would like to change with those pins,
you may also check the “customer usage” for those pins, there’re default board configurations for your reference.
thanks

Hi JerryChang,

I just want to use them the standard ways.
After reading the product design guide, the ‘*’(asterisk) just means the pins are ACTIVE LOW signals, right?
Is there any thing else I need to take note of when using these signals with "*"in the end (default config)?

Thanks
Kien

Hi kiennus84,

You can ignore the statement in pinmux:
Please check with Nvidia before using functions that end with a ‘ * ’
We will get it removed from spreadsheet.
and you can use the pins in the standard way.

Thanks,
Shubhi
