IWR1843 and DCA1000EVM: mmwave studio radar api capture and post processing have a fault

Dear supporter:

          I am using  iwr1843 and DCA1000EVM to capture the mmwave radar's data.when i use the mmwave studio 2.1.1.0 to capture and post processing ,the output window display some messages as follow:

[16:56:36] Start Record command : Success
[16:56:36]
[16:56:36] Record Process :
[16:56:36] Timeout Error! System disconnected
[16:56:36]
[16:56:36] Record stop is done successfully
[16:56:36] [RadarAPI]:
[17:04:29] [RadarAPI]: ar1.StartMatlabPostProc("C:\\ti\\mmwave_studio_02_01_01_00\\mmWaveStudio\\PostProc\\adc_data.bin")
[17:04:29] [RadarAPI]: No of files Captured: 0, Total no of frames for each device : 8
[17:04:29] Error : The number of files captured is zero!

so i check the path and the file,there is not a file named adc_data.bin in the path.

i have check the configuration.step by step follow the assist files(User's Guide for mmWaveStudio 3.0.0.14)

I don't know how to solve the problem.hope you can give me some advice.

Best wishes ,Thank you ~~~~
