CPU2 and 3 never function

Autonomous Machines Jetson & Embedded Systems Jetson TX2

I have the MAXN profile enabled and jetson_clocks on, yet when I do benchmarks those 2 cpu’s don’t seem to run. Any ideas? Jetpack 4.4.

I tried the previous fix listed here…

  1. sudo vim p2771-0000.conf.common
  2. Remove “isolcpus=1-2”:
    CMDLINE_ADD=“console=ttyS0,115200n8 console=tty0 fbcon=map:0 net.ifnames=0”;
  3. Flash kernel-dtb:
    $ sudo ./flash.sh -r -k kernel-dtb jetson-tx2 mmcblk0p1

didn’t work.
Jetpack 4.4 sucks…

hello vondalej,

could you please also execute $ nvpmodel -q to print the current power-modes,
and, please enable tegrastats utility to gather statistics reports for reference.
thanks

hello vondalej,

okay, it seems wired that those two CPUs were zero usage.
could you please run some samples or stress application to confirm they’re actually zero usage.
thanks

I have run stress several times. ZERO usage.

hello vondalej,

it looks like you’d replied the original thread, Topic 124708. let’s keep using same discussion thread for further supports.
thanks
