Can someone explain to me why the numbers on SPI don’t line up in multiple places.
For instance, in the pin mux spreadsheet, on SOM pin 106 I see the Jetson Orin Nano Function listed as “SPI1_SCK” yet if I go over to customer usage and change what I want to use it for, it’s listed there as “SPI3_SCK”. I also notice in the 40 pin header config it is now listed as SPI3 as well.
How did SPI1 go to SPI3? Is there some kind of convention here to keep this all straight for me? Thanks!
We are using three boards; custom board, XavierNX board (for HDMI) and Orin Dev board. Thanks for the pointer to where these are defined. Was curious why not use the SoC signal names since module is such an arbitrary connotation.
The reason I say is that these numbers get translated into 3 different values by the time they get to the user
