Getting IPU Warning - IPU_INT_STAT_9 = 0x08000000 from time to time

I get the above warning with our driver. Per docs it is

27_IC_ENC_BUF_OVF  This bit indicates on an interrupt that is a result of the IC Buffer overflow for encoding coming from the IC.

. It looks like it does not cause any serious trouble, but anyway i want to fix it.

What can be the cause of such an issue, and what should i check.

Hi David

in general such errors are caused by performance issues, that is IC

has not ability (sufficient time) to process incoming frame.

You can find experimentally (decreasing incoming frame rate or frame size or

skip some processing algorithm) where in code this happens.

Best regards
