Why my TX2 always only has 4 CPUs working

[czq99]

Hello! I would like to ask why my TX2 always only has 4 CPUs working, and the usage rate of CPU2 and CPU3 is always 0. My current working mode is MAXN 0

There was a thread for this

2 cores at 0%

Hey, I took a fresh flashed Jetson TX2 device (Jetpack 4.4) and activated all cores sudo nvpmodel -m 0. After that, all 6 cores were displayed in htop, but core 2 and 3 are always at 0%. What can go wrong there? [grafik]
