Hi, DJI families.
I'm using M300 RTK model to develop third party sensor using PSDK.

My sensor is based on linux, and need high voltage power over 13.6V.

I tried to get 17V from Expansion board, but there is some problem.

Here is what I have done.
1. Connect Payload's GPIO pin to Expansion board's HPWR pin & Ground pin to apply 3.3V

2. Tried to edit PSDK code.

And there is problem
1. PSDK code comments says that the power management code does not apply high voltage in linux environment.

2. I don't understand the comments, so I editted the code to return SUCCESS every time.

3. There was a segmentation fault error -> maybe memory error in C code.

Can I get any advice for the high voltage application?
