Original question:

DCA1000EVM: Cannot establish ethernet connection - FPGA not found

DCA1000EVM: DCA1000EVM+IWR6843aop Without LVDS data in data collection

?? ?

Part Number: DCA1000EVM

Tool/software:

When attempting to collect data using mmwave studio, DCA1000 and radar are connected normally. After clicking the DCA1000 EVM button, the start record command was successfully transmitted, but the LVDS data was not transmitted. We suspect it is a configuration issue with DCA1000. The images show the actual product and the output from mmwave studio.

    Hello,

    No LVDS data means that the mmWave sensor was unable to start. This is usually due to a bad chirp parameter that creates an impossible to deploy chirp design which when given to the radar sensor prevents it from starting. Did you change any default values before doing so? You can also run the script C:\ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\DataCaptureDemo_xWR.lua which is to be ran after the sensor and DCA1000 is in the connected state.

    Best Regards,

    Pedrhom
