Hi, Xavier OEM says PCIe RESET_N, CLKREQ, and WAKE_N signals are “CMOS – 1.8V”. I also read through Xavier devkit schematic. I can see that they are directly connected to M.2 M key and M.2 E key connectors WITHOUT going through any voltage level shifter. Should these signals converted from 1.8V …

PCIe RESET_N, CLKREQ, WAKE_N voltage level at M.2 M and E key
