I’m a newbie in electronics and I’m trying to connect two agx developer kits, one of them is RC and the other is EP.
We’ve made the swap board by referring to the guide document.(Jetson_AGX_Xavier_Series_PCIe_Endpoint_Design_Guidelines_DA-09357-001_v1.3.pdf)
Note: If the two Jetson AGX Xavier devices shown in Figure 1 are on separate systems, then the power rails should not be connected between the two. The grounds for each system should be connected.
Q1. I’m not sure what it means that ‘power rails should not be connected’. If you don’t mind could be give me a detaild explanation with example?
Q2. We connected GND of all 4 ODs to RC side B4 (ground), please let us know if it is right.
PCI Express - Wikipedia
According to the PCI express connector pinout table, the B4 is ground.
