Thanks a lot for your response, I have the freedom of setting the dumb (no USB-PD) input voltage to anything between 10-20V and in terms of Current, I have upto 6 Amps available so that should cover the requirements of Orin very well.
I would like to use the USB-C plug and not the Barrel plug to connect because of issues we had with the barrel plug previously. The setup is for an RC car that is driving Off-road and has a lot of vibrations and USB-C has been better than the Barrel jack in terms of connector reliability. It is not possible to use the provided 19v adapter because of obvious reasons.
I tried to power the Jetson with plain 19v, 6 Amps peak bench power supply but could not manage to get it switched on.
My question is, with the 19v on the USB-C connector, why wont the AGX Orin power on? What am I missing?
