Insert the SD card into the jetson xavier nx developer kit, install jetpack 5.1 using sdkmanager, remove the sd card, and insert the sd card with jetpack 4.5.1 version installed, it will not boot.
I think it should work, but why doesn’t it work?
And when the test was conducted with the RealSense camera
There is a clear performance difference between jetpack5 and jetpack4.
Hi, bootloader is burnt into the QSPI memory on your device, not SD card, so you could expect that bootloader designed for JetPack 5 would not boot an SD card flashed with JetPack 4.
For the performance difference between JetPack 4 and JetPack 5, do you have any table or log showing it?
Looks like you device runs at different power mode under JP4 (15W 6CORE) and JP5 (20W 6CORE).
Can you adjust them so both version run at the same power mode? Click the NVIDIA icon on the top-right corner of the screen to make change.
If the issue is still the same, please provide us the code and the environment you are using, so we can try if we can re-produce it.
Hi, can you try run a clean install of JetPack 5 without ROS, and see if the CPU usage is still over 20%?
Also, do you experience difference in terms of time when building OpenCV from source on these two versions?
