Original question:

CCS/AWR1843BOOST: Where are the TI resources explorer labs, experiments and chirp examples for this board?

CCS/AWR1843BOOST: compatibility between labs for AWR1642 and AWR1843

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1642, , AWR1843

Tool/software: Code Composer Studio

Hi, a time ago I asked a similar question in this forum

then you told me that the labs between boards are compatible, so all this time I have been working in my AWR1843BOOST EVK with no issues with source code from CCS rebuilding and loading labs for AWR1642 or AWR1843 in debug and deployment mode

But now I am having issues flashing binaries using source code from CCS for a custom awr1843 board (only works flashing the MRR or MRR steering lab) so I was searching info in the forum and here you say this:

"You may need rebuild the application while selecting AWR1843 device in CCS project properties setting"

and here you say this:

"An application written for AWR1642 will run on AWR1843 without recompiling as long as the adjustment is made in the chirp config file to use Tx antennas 1 and 3 verses antennas 1 and 2 on the 1642.  If you want to port/rebuild the application from 1642->1843, two things must change:

1) the pinmux statements that configure UART, SPI, CAN, etc.  These are usually done in the MSS, and should be wrapped in #ifdef SOC_XWR18XX ...  #endif statements.

2) SOC_XWR18XX will need to be defined for both MSS and DSS builds instead of SOC_XWR16XX "

So now I am confused, why do you say I need this extra steps to run a lab made for AWR1642 in the AWR1843?, in my EVK I never needed this steps, do I need to do this for a custom board?, somehow the AWR1843BOOST EVK firmware knows that an AWR1642 code is being loaded and allows that kind of config?

thanks

    HI,

    Please download from the TI Resource Explorer (dev.ti.com) the following version of the Automotive Toolbox

    \mmwave_automotive_toolbox_2_9_1__win\mmwave_automotive_toolbox_2_9_1\labs\lab0003_occupancy_detection\src

    In this folder you will find ccs projectspecs for 16xx and 18xx.

    As you can see, in order to re-build a 16xx demo for 18xx you will need to create a similar ccs projectspec for 18xx

    thank you

    One more thing,

    You will also need to perform some minor updates to the profile configuration.

    Please compare the differences for

    \mmwave_automotive_toolbox_2_9_1\labs\lab0003_occupancy_detection\chirp_configs\od_demo_16xx_4zone_strong.cfg

    \mmwave_automotive_toolbox_2_9_1\labs\lab0003_occupancy_detection\chirp_configs\od_demo_18xx_4zone_strong.cfg

    Notice the differences for

    • channelCfg - for 18xx the numbering of enabled antennae is different (101 =5) instead of (011 = 3) on 16xx
    • chirpCfg - for 18xx the numbering of the Tx antennae is different

    Thank you
    Cesar

    If these steps are required so why I can run the awr1642 labs in the awr1843boost evk (and works) without that modifications?

    It works, but you are using the wrong antennae on 1843

    Thank you

    Hi, ok, I understand that I should reconfigure the antenna code but I think that this step is not neccesary:

    because without this the app runs in the AWR1843BOOST, right?

    The code runs, this is correct.
     
    However if the antennae are not correct the angle estimation will not be correct.
     
    So, for correct operation you will need to re-build the code as mentioned before.
     
    Thank you
