Please check the reason why this clock-range value has changed. ( please check history )
FYI, INTEK's clock-range is <334 334>.

Hi Jung

This is for screen compatibility.
I found a similar mantis to talk about this 4 years ago.

Hi Kinbay

1) If we set the clock-range = <334 334> what issues can be observed?

2) What VPU version do Smart3 STB currently use on OS12?
    ( If we can check with the code, please let me know the location of the code. )

Thank you

 ==> This suggests from amlogic, please contact amlogic for more detail.
2) What VPU version do Smart3 STB currently use on OS12?

Hi Kinbay

When I checked with SPTEK, common has the same AT100_5.4.2_Sprint2 and BFX-AT100_5.4.2.

Therefore, you can push to BFX-AT100_5.4.2

Thank you
