WARNING: at platform/drivers/pg/pg-cv-t194.c:73

I get a lot of these kernel messages, especially when running things like jtop. I can’t seem to find that source file pg-cv-t194.cin any of the kernel or driver sources. Anyone know where this file is located or which package it comes from? Anyone know what causes it?

I try below on J4.4 didn’t see this message.

sudo apt-get install python-pip python-dev build-essential
sudo pip install --upgrade pip
sudo -H pip install jetson-stats
sudo jtop

That’s odd. I get them even during the boot process. I should have said… These only appear on the serial console and not in any of the logs or even dmesg.

Hi,

These prints are from our power and clock management software which is not open source. You can ignore these prints .
We have suppressed these prints in future release. These comes when CCPLEX wants to railgate some rails which is not supported for jetson NX platform.

thanks

Thanks for the info!

@Bibek is there a way around these messages. They are making my console unusable.

Are they printk messages I can suppress? I’m on Jetpack 4.4. Is there a binary from Jetpack 4.4.1 that I can swap in?

Use TCU muxer and get only ccplex logs
