Hello, I am using a TX2 to build an autonomous RC car. I need to know if I can monitor the VDD_IN pin and set a minimum voltage to initiate a controlled shutdown when VDD_IN detects the minimum voltage.
I found a command that, when entered into the terminal, returns the value of VDD_IN in milivolts. Beyond that, I’ve found nothing besides the guides directly from Nvidia about the power, voltage, and current monitors. The reading returned from the command I put into the terminal was only .02 volts from what I read on my voltmeter, so a software solution would be wonderful! Any and all help is greatly appreciated!
I can’t for the life of me find the directories that are mentioned in this document that lead to the .dtsi file. From my NVIDIA directory, I don’t find the platform directory. Any advice on how to get to the .dtsi file?
I did find source_sync.sh, and ran that. However, I did not find the powermon file I’m looking for still. Still searching for a way to perform a controlled shutdown at approximately 9.4V at VDD_IN via software.
