AWR2544LOPEVM: Zeros (0x00) appearing inside Ethernet payload data – how to resolve?

Tool/software:

Hello,

I am using the AWR2544LOPEVM to stream radar cube data over Ethernet. When I capture the data using ROS, I observe that long sequences of 0x00 values appear in the middle of the payload.

• My current configuration is N_c = 256, T_c = 60 µs, 2× mode.

• I have tried adjusting ethPktRdyCnt and ethPerPktDly (e.g., 6/0, 4/0, etc.), but the same issue still occurs.

• In the post-processed range profile, these inserted zeros look like artificial noise or corruption.

Could you clarify whether these 0x00 sequences are expected (e.g., padding during Ethernet transmission) or if they indicate a problem in the transmitter configuration (such as ethPktRdyCnt, ethPerPktDly, or compression settings)?
Also, are there recommended settings or checks to reduce or eliminate this issue?

Thank you.
