We’re a little confused about how many SPIs are available/supported on the Xavier NX module. Table 10-6 of the Xavier NX Product Design Guide suggests that SPI is also available on GPIO03/04/05/06 and that this goes to SPI2 inside the SoC. However, Figure 10-2 only lists SPI1 and SPI3 as being available in the SoC, instead of all 3 SPI controller instances (SPI1/SPI2/SPI3) that the SoC has inside it. Is SPI2 functional/supported/validated for customer use?
In the v1.06 Xavier NX pinmux spreadsheet, it is not possible to select SPI2 functions for the SPI2 pins (spreadsheet drop-downs in cells AQ165 to AQ168); if SPI2 is indeed supported for customer use, could a fixed spreadsheet please be released?
