Jetson nano 2gb not boot when power supply on GPIO

Hi,

I am using jetson nano 2gb for the first time. I connected power supply(s) to GPIO pins.
Whenever I switch on the board from the green LED is turned ON and automatically it gets shutdown in a few seconds.
I tried with multiple power supplies same result. (greend led is switch off after few seconds)

  • 2.4 A usb charger
  • powerbank
  • 5v 30 A led power supply

When I connected led power supply to usb-c, the board booting fine.

What is the difference between the two inputs? What could be the problem when the GPIO gets power from the board?
Thanks and Regards,
Gyula

hello szivgy,

please check, Getting Started with Jetson Nano 2GB Developer Kit.
you’ll need to use USB-C power supply (5V⎓3A),
thanks

I tried based on user guide information. user guide Power via 40-pin Header section

" Power via 40-pin Header

The developer kit can be powered by connecting the 40-pin header’s 5V pins to an external power supply, Each of the two pins will support 2.5A.

Do not power the developer kit via 40-pin header pins and USB-C connector at the same time."
This information is not up to date?

The type-c port and 5v pins of 40-pin header share same VDD_5V_IN netlist. It should be same to power from type-c port or 5v pins.

Did you measure the real voltage level on the pin when using 5v pins? Is there any voltage drop on it when shutdown happen? It might be the issue of heavy workload and high voltage drop on the cable.

Thank you for your answer!
I only have multimeter, I didn’t see any voltage drop on it. The cable length is only 15 cm. I use normal pin cable.
What is the recommended cable thickness?
I use same power supply (5v 30 A led power supply) both case, but the board only starts if I use a usb-c connector.

Please use a scope to check if any voltage drop when shutdown happen.
