Hello ,

Have followed the below step mentioned in the mmwave-sdk-user-guide ?

Without powering off the board, connect the board to CCS. (See section How to connect xWR14xx/xWR16xx EVM to CCS using JTAG for details on how to connect to CCS). Load the symbols for the capture demo application using executable file provided at mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\xwr14xx_capture_demo_mss.xer4f.
In CCS Expressions window, view the global variable gCaptureMCB and check DMA interrupt counter(dmaIntCounter) and chirp interrupt ounter(chirpIntCounter) after sensorStart command. The chirpIntCounter should match the configuration. Forthe above configuration, the counter should be 128. The dmaIntCounter will be the actual number of DMA transfers triggered.

To add on this answer, the variables and and expressions windows are cleared when CCS is loaded. A variable or expression can either be added in manually or done by using the "Load" option in CCS. Feel free to reply if you have any additional questions or need more information.

The correct command for this demo is "sensorStart". In your first attempt you issued the command "sensortStart" which is an invalid command. Our SDK provides a script that implements all of the commands that you need to correctly run this demo. Based on which high speed interface you use, there are two possible options:

Option #1: CSI-2
mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\csi_stream_demo_script.txt

Option #2: LVDS
mmwave_sdk_<ver>\packages\ti\demo\xwr14xx\capture\lvds_stream_demo_script.txt

Please let us know if you still have any issues after using these provided scripts.

Kyle

The adcCfg line should be: adcCfg 2 2

Please give that a try and see if it works. Let us know if you have any questions.
