@Seeed_Jostar I have the same problem on my Orin NX 16GB after flashing to JetPack 5.1.2 using Nvidia SDKManager. I noticed that the factory firmware that came with the Orinx NX RE-computer series runs 35.1.2 and that works. The SDKManager runs 35.2.x+ (USB C does not work) and does not allow for flashing 35.1.2 on Orin NX. Any updates from your end that can fix the problem?
