Sequence between SYS_VIN_MV/HV

Hi all,

We notice the sequence between SYS_VIN_HV and SYS_VIN_MV as shown in the figure below. (Jetson AGX Orin Series Design Guide v1.2)

The results we measured on the devkit board were the same as in this thread. HV is earlier than MV during power-on. This is the opposite of what the guide suggest. https://forums.developer.nvidia.com/t/sys-vin-hv-mv-sequence/227642

It seems like the ≥1ms timing is necessary, and early devkits did not adopt correct design.

What I want to know is why a time difference greater than 1ms is needed here?
If it is so important, why does the devkit run without problems?

Although NVIDIA gave advice, I was more interested in understanding why. Thanks!

As said in that topic, it is a new finding and early devkit do not meet that. No more info can be shared.

Hi Trumany,

Thank you for your reply.
