Hi @ShaneCCC! 😄

Thanks for this. Do you know how I can convert the pin values to the Board numbering e.g. those found in the 40-pin GPIO header figure @KevinFFF posted here? 🔢

Thanks!

=> It is labeled SPI1_MOSI from Figure 3-5.
=> And you can find the following info in Table 3-4.

=> It also can be found in AGX Orin pinmux spreadsheet as following:
