failed to set power mode when running realsense d4xx on the jetson orin nano

[stevedanomodolor]

I am connected to a realsense d4xx camera and i am trying to run the depth sensor and the color sensor at the same time. I noticed that after setting both camera and opening it, i get the following exception using the pyrealsense2 python library “failed to set power state”

I am using a power supply that is 5v and 2.3 A. It seems to happens only when i try to set both camera sensor, It happens always on the “device = device_list[selected_ind]” line of the following code of pyrealsense. Is this a power issue?.

i am running the latest jetpack 6.1 super on max mode and I also did the jetson_clock.

context = rs2.context()
device_list = context.query_devices()
if len(device_list) > 0:
selected_ind = 0
device = device_list[selected_ind]
usb_descriptor = device.get_info(rs2.camera_info.usb_type_descriptor)
if “3.2” in usb_descriptor:
return 2
else:
return 1
else:
return 0

Hi @stevedanomodolor For the Jetson Nano board, Intel strongly recommend enabling the barrel jack power connector for extra power by following instructions at the link below. I assume that the same power recommendation is applicable to the Orin Nano model's barrel jack.

I am using the Jetson orin nano see https://developer.nvidia.com/embedded/learn/get-started-jetson-orin-nano-devkit, would it be enough just to get a power supply with 5v 4A?. In this case the step to enable the barrel connector isn't necessary right?
