TDA2SX: hdmi flickers in tidl_od usecase

Expert 1615 points
Part Number: TDA2SX


we use vision_sdk 305,

and change tidl_od chains for our requires,

our system fps is about 17, HDMI is set SYSTEM_STD_1080P_60

What will the possible cause if the HDMI output flickers once in a while? 

in our other application on tda2eg, surround view chains,

the system fps is 30, HDMI is set SYSTEM_STD_720P_60

the HDMI output is normal, 

we know tidl_od system has high load, like ddr data transfer....etc,

is this the root cause for HDMI output flickers?
