DCA1000EVM: Data capturing issue on DCA1000 for larger No of Frames: The process cannot access the file because it is being used by another process

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR2243BOOST

Hi,

I get the following error when changing the number of frames to 128. I am using AWR2243BOOST and here are the lines in the lua script

if (ar1.FrameConfig(0, 0, 128, 128, 40, 0, 1) == 0) then
WriteToLog("FrameConfig Success\n", "green")

The script works fine for lower No of frames (like 64). The output of the script for 128 is:

[01:15:44] [RadarAPI]: ar1.StartFrame()
[01:15:44] [RadarAPI]: Status: Passed
[01:15:44] Frame start async event received!
[01:15:49] Frame End async event received!

Hello Daniel,

What is the DCA1000 FPGA firmware version and mmWave studio version you are using for this experiment? I have seen this error a couple of times when the FPGA FW is not updated. Could you please ensure you're using the latest version i.e. v2.8.

Regards,

Ishita

Hi Ishita,

It looks like I am using FPGA version 2.8 as shown below with mmWave Studio 03.00.00.07. If I am supposed to use a different version, please provide me with the instruction on how to upgrade.

[01:15:42] [RadarAPI]:
[01:15:42]
[01:15:42] FPGA Version : 2.8 [Record]

Thanks,

Daniel

Hello Daniel,

The latest FW version is 2.8, so you are using the correct one. Could you send the entire mmWave studio output log in case of the failed session? I will analyze that and get back.

Thanks!

Hello Daniel,

I see that you're using the DataCaptureDemo_xWR.lua script. I would want you to try out two things :

1. Try to do this experiment manually and see if it produces the same error.

2. If the above works well for you, can you increase the delay of waiting for 128 frames in the script to twice of what you had when capturing 64 frames? This is to give enough time for DCA1000 to capture and then start the post processing in mmWave studio. Increase the delay after start_frame command.

Regards,

Ishita

Hi Ishita,

Increasing the delay worked. Please note that I am still seeing the Post Processing crashing the mm Wave Studio. Please see below:

Hello Daniel,

Let me check with the studio team on this and I will get back to you by the end of this week.

Thankyou for your patience.

Hello Daniel,

Sometimes this can happen due to overload. Recently, a new version of mmWave studio (ver 03_00_00_14) was released on ti.com. It might be a good idea to upgrade to that version and see if it crashes here as well.

Also, are you running mmWave studio as an administrator?

Ishita
