Hi,
I’m using custom carrier board without any display/hdmi port. TX2NX on Jetpack 4.6.2.
But nvphs service looks failed to run

Tried to set display_state_fmt=/dev/null
in /etc/nvphsd_common.conf
file. The nvphs
service looks running, no error log in nvargus-daemon
, but nvphs
service generates error log every second:

Does this error log impact other parts? Or how to configure nvphs correctly for system without display?
This issue doesn’t happen on JP4.5.
