AWR1843BOOST: MRR Lab - Data collection and Debug

Sarat Kothapalli

Part Number: AWR1843BOOST

Hi,

We have started using experimenting with MRR lab and have few questions regarding that.

1)  We have observed a lateral bias and tried to follow the phase calibration procedure. it had worsen the problem. Is there any other way to fix the bias issue ?

2)  is it possible for you to provide a . cfg file or a Lua script that contains all the advanced subframe chirp parameters used in MRR lab, so that we can use it to collect the data using DCA 1000 EVM ?

     or perhaps provide a link on how to program sub frames in MMwavestudio ?

3) Do you have any sample project files that uses the .bin files as input to debug the code ?

Thanks in advance.

    Hello Sarat,

    For now, I can only answer a part of your concern. 

    2) We only provide a handful of reference scripts with the labs, you could use that to create your own script based on your usecase.

    The configuration defined in the MRR Lab can be found at the following location:  mmWave Sensors\Automotive toolbox\labs\Medium Range Radar\CCS Project\common\mrr_config_chirp_design_x.h

    You could also refer to Chapter 11.1 "Advance Frame Configurations" in the mmWave_dfp_user_guide.pdf  which comes as a part of the DFP package (<download directory>\mmwave_dfp_<ver>\docs). This document explains about advance frames in detail.

    Basically, in this configuration, user can configure multiple type of frames as compared to legacy frame configuration where only one type of frame is permitted. You can configure only upto 4 subframes, but to provide maximum flexibility, each of the sub frames consists of multiple bursts of chirps (up to 512 bursts) and each burst can consist of 512 unique chirps which are associated to one of the 4 profiles. 

    Hope this information helps. I'll forward your query to our expert for the rest of your questions. Due to year end holidays, our responses might be delayed. Sincere apologies for that. Please wait until the end of next week.

    Wishing you a very Happy New Year.

    Regards,

    Hello Sarat,

    1) could you provide more info or your result data for offset in the lateral bias with MRR which you are observing?

    3) Every lab example comes with default CCS debug images (MSS: *.xer4f, DSS: *.xr674)

    For MRR lab you can use mrr_18xx_mss.xer4f and mrr_18xx_dss.xe674 files with CCS to debug the code.

    C:\d-drive\ti\mmwave_automotive_toolbox_3_0_0__win\mmwave_automotive_toolbox_3_0_0\labs\lab0007_medium_range_radar\prebuilt_binaries

    And for this you need to flash the ccsdebug.bin file first the device. Please follow the instruction in the mmWave SDK user guide (C:\ti\mmwave_sdk_03_05_00_01\docs\mmwave_sdk_user_guide.pdf: setion:3. 2. 2. CCS development mode)

    Regards,
