AWR2243: Capture Card timed out

Part Number: AWR2243
Other Parts Discussed in Thread: MMWCAS-DSP-EVM, MMWCAS-RF-EVM, AWR1843BOOST

Hi

 

I tested with MMWCAS-DSP-EVM/MMWCAS-RF-EVM by referring "mmwave_studio_03_00_00_14のmmwave_studio_cascade_user_guide.pdf".

 

I'd like to know the way to set the value "1" at "No of Chirps Loops" in SensorConfig Tab.

Because, I'm facing trouble at the following condition:

   > [RadarAPI]: ar1.FrameConfig_mult(1, 0, 0, 0, 1, 1, 0, 1)

   > [RadarAPI]: ar1.FrameConfig_mult(14, 0, 0, 0, 1, 1, 0, 2)

   > [RadarAPI]: ar1.TDACaptureCard_StartRecord_mult(1, 1, 0, adc_data1, 0)

 

The error logs are:

   > [10:40:18]  Create Application Response from Capture Card timed out!!

   > [10:40:18]  TDA ARM Failed

 

(If I set the value "2" at "No of Chirps Loops" then the timeout doesn't occurred.)

 

Thanks and Best regards,

Tsurumoto.

    I did take a look at your frame configuration shown above. Why are you configuring the "number of frames" to be transmitted as zero? This is the main reason you're getting that error. You need to capture atleast one frame of data.

    Can you correct this and try again.

    Hi Ishita

    We need to continue to capture the ADC data during 7 minutes in the condition of periodicity = 1ms, number of chirp = 1.

    If "number of frames" is set to anything other than 0, the maximum value is 65535, which does not meet our requirements.

    We was able to capture the ADC data by setting it to 0 With AWR1843BOOST + DCA1000, but is it not possible with MMWCAS-DSP-EVM / MMWCAS-RF-EVM?

    Even if "number of frames" is set to 0, we have confirmed using a spectrum analyzer that radio waves are being transmitted from the EVM.

    Thanks and Best regards,

    Tsurumoto.

    Hi Ishita

    Do you have any update?

    Hello Tsurumoto-San,

    Sorry for the delay.

    Also, I apologize for the misdirection in my previous reply. Configuring "number of frames" as 0 leads to an infinite capture time and hence that should work, so it is not the frame config that is causing that error.

    In your related post, where you have also attached the mmWave Studio log, I see you're using only one chirp i.e Chirp 0 in your chirp configuration which leads to TDA Configuration with Width : 2048 and Height : 2

    I believe this can be a limitation i.e height cannot be less than 2 and configuring one chirp will configure TDA Height as 1. But I'm not 100% sure on this. Let me check this with the concerned team internally and I will get back to you by Wednesday.

    Regards,

    Ishita

    Hello Tsurumoto-San,

    Yes, my assumption was right. TDA Height = 1 is not possible. You need to have minimum 2 chirps in a frame to have a minimum height of 2.
