What is the extend of damage if DP1_HPD pin is pulled-up to 3.3V by a 10k resistor? I checked the resistance is 10M while new module (or the module used on 1.8V pull-up) is 24M. Looks like a 10M leakage is not a huge damage, however I am not sure on the long run. On the pinmux, there is an option to enable 3.3V tolerant, but the datasheet/design guide mentioned this pin is a 1.8V CMOS (no mention of being 3.3V tolerant). Does this 10M means this pin is actually protected against 3.3V input?

If 3V3 tolerance is not enabled in the pinmux it will damage the pin on Orin. Please refer to Q17 in Jetson AGX Orin HW FAQ - Jetson & Embedded Systems / Jetson AGX Orin - NVIDIA Developer Forums
