I have an OrinNX 16GB developer kit. When I set the power profile to MAXN it enables 8 CPU cores and puts GPU frequency to 918Mhz. However, after some time I observed that 4 of its cores are disabled. I don’t know what is the trigger but it has happened multiple times.
According to /etc/nvpmodel.conf, power model MAXN should have all CPU cores online (pasted below).
Any idea why this might be happening?
