TDA3: Behavior of reception completion notification of ISSCapture

Part Number: TDA3

Hello Experts,

We're evaluating our system using PSDK RADAR v3.2. I understand that the ISS capture driver issues a reception completion notification (SYSTEM_CMD_NEW_DATA) when it receives AD data all for one frame from AWR1243. Is it correct?

However, for example, in the case of 256 AD * 128 chirp, I saw a phenomenon this was notified even though only about 256 AD * 100 chirp was received, and the FFT processing by the subsequent EVE were executed.

Can you think of anything that might have caused it?

Regards,
Kzk

    Hi Kzk,

    This is very strange. Can you please let us know how are you confirming that only 100 chrips have been recieved?

    There is a bug fix in the PSDK Radar 3.6 which fixes the CSI Capture output container format which is not set to 16 bits in the Radar configuration.

    Can you please check if this is applicable to you?

    You would need to add the below line in the function ChainsCommon_ar12xxSetIssCaptureParams of the file vision_sdk/apps/src/rtos/radar/src/common/chains_common_ar12xx.c

    pPrm->outParams[i].outBpp = SYSTEM_BPP_BITS16;

    Thanks and Regards,
