DM385: Change ISS clock can influence video data frame rate

Part Number: DM385

Hello!

I have situation, similar to described in "Change ISS clock can influence video data frame rate" tread,

just with DM385 (813x) processor.

When PLL_MEDIACTL registers are changed in u-boot, it looks like real ISS clock also drops (in my case from 400 to 200 MHz).

I can see that, for instance, from power consumption decrease.

But xdc function Timestamp_getFreq(&cpuHz) continues to return 400MHz value, thus misorienting

time measuring utils, like Utils_getCurTimeInMsec() (from src_bios) and, in turn giving twice higher values for FPS.

Where in software I can make adjustments for  correct frequency and time values in this case?

Regards
