Team please support. We require your assistance urgently.

Hello,

You mentioned “NV board”, so is this issue on nv devkit?
How is the reproduce rate of this error ?

Yes.
It produces rarely not frequently.

We just want to know the root cause of this error. Because this error produces only 4 times out of 100s testing.

Hi,

We will check this issue. It means frequency monitor is seeing limits violation.

Thank you.

what power supply you are using.
this prints comes when the freq of that particular clock is not what sw is expecting.

Hi,

Also, can you share the complete uart log when the issue happens. you may type dmesg to reprint the kernel log after the issue is seen. I am looking for any OC throttle happening when the issue is seen

thanks
Bibek
