TDA3XEVM: How to save the raw Radar ADC data in CCS project in SDK

Adam Yao94020

Part Number: TDA3XEVM
Other Parts Discussed in Thread: AWR1243

Hi champion,
I am running the Radar (single AWR1243) Capture + Null(TDA3x only) and want to capture the raw ADC data for advanced frame in CCS. I could not find the instruction to do it in CCS. The SDK I use is PROCESSOR_SDK_RADAR_03_02_00_00.
Could you help to give me some suggestion?

Thanks,
Adam

Hi Adam,

You can try the following steps to dump the frame from CCS for the Capture + Null usecase.

1. Place a break point at NullLink_drvDumpFrames in IPU1_0
2. Add the following expression in the CCS expressions window:
(System_VideoFrameBuffer *)pBuf->payload
3. Expanding this structure would show you bufAddr[0], this contains the buffer address for the ADC data.

The size of the ADC data is ((128 x 4 Bytes + 4 Bytes CP) x 4 Rx + 16 (for CSI Alignment)) * 128 chirps * 2 Tx.

Thanks and Regards,
Piyali

Hi Adam,

As discussed yesterday, the above steps are applicable for normal and advanced frame. The pitch of the frame is determined by the largest configuration of ADC samples in the subframes.

Please feel free to mark this answer verified.
