AWR2944EVM: the AWR2944 TDM Ethernet demo runs for a short time and stops

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944

Hi,

I'm using the pre-built demo at mmwave_mcuplus_sdk_04_07_01_04\ti\demo\awr294x\mmw\awr2944_mmw_demoTDMEnet.appimage, following the guide in sdk user manual.

The demo runs correctly at first, but stops only after few seconds (typically 5-20s). It seems that the data from com port and Ethernet port stops at the same time, becaue the plot in demo visualizer and the captured data in wireshark stops exactly at the same time, looking like the MCU encountered some error.

The cfg I give 2944 is edited only with the remote IP, from profile_enet.cfg. I gusse maybe the frame period is too small for radar to both upload the data to com port as well as Ethernet, causes the RTOS broken.

How can I make this demo runs stably and persistently? Thanks.
