I’m interested in designing a custom carrier board with an AGX Xavier. I also want to design it so that it is forward compatible with the AGX Orin. The purpose is specifically for PCIe, where there will be three 4-lane buses. My questions are as follows.
1. Single Node Network (SNN): Is it possible to use the AGX Xavier pins connected to the SNN nets for high-speed differential signals (PCIe), or are these pins just dead ends?
Thank you for responding. It appears that I was using an outdated version of the Jetson AGX Orin Series and Jetson AGX Xavier Series Interface Comparison and Migration (DA-10655-001_v1.1 | March 2022). I see that there are only 2 configurations listed in the newer version (DA-10655-001_v1.2 | June 2022). Your answers for questions 2 and 3 are very clear.
Do you have an answer for question 1? Are the NVHS1 pins connected to the SNN nets usable on AGX Xavier?
