AWR1843: About application settings of AWR1843

Hiroyuki Kanematu
Expert 2975 points
Part Number: AWR1843
Other Parts Discussed in Thread: UNIFLASH,

Hi, I have a question about setting up AWR1843.

What is the process required to set the SW from the time of purchasing the AWR1843 alone?
(BootLoader settings, API settings, ROM write settings, etc.)

What equipment or SW do you need to do that?

P.S.
In the case of AWR1843Boost, I could immediately write the SDK demo file (.bin) via UniFlash, but I don't know what I need to do when it comes to writing the program to AWR1843 itself.

    Hi,

    Do you want to load the the program through CCS?

    You would need to build the executables. In the mmWave SDK demo, the pre-built binaries are provided in

    mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\xwr18xx_mmw_demo_dss.xe674

    mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\xwr18xx_mmw_demo_mss.xer4f

    Thank you

    Cesar

    Thank you for answering the question.

    > Do you want to load the program through CCS?
    I'm thinking of loading the program with CCS or Uniflash.
    However, I think it is necessary to start the boot loader of AWR1843 before that.
    Does the SDK demo file even include booting BootLoader?

    Which files in the SDK contain the pre-build files (especially the source code)?

    I think it is the following file.
    C: \ ti \ mmwave_sdk_03_05_00_04 \ packages \ ti \ demo \ xwr18xx \ mmw \ dss

    C: \ ti \ mmwave_sdk_03_05_00_04 \ packages \ ti \ demo \ xwr18xx \ mmw \ mss

    p.s.
    I would also like to know about each role in the demo file.

    Hi,

    In order to understand how to run the mmWave SDK demo with Uniflash and CCS I think it will be helpful to start reading the mmWave SDK User Guide

    C:\ti\mmwave_sdk_03_05_00_04\docs\mmwave_sdk_user_guide.pdf

    Please see

    • 3. 2. Loading images onto mmWave EVM

    This section also describes which are the executables. They are different for Uniflash load and for CCS load.

    In order to understand the operation of the demo, please review the demo documentation

    C:/ti/mmwave_sdk_03_05_00_04/docs/mmwave_sdk_module_documentation.html

    Thank you

    Cesar

    Hello, the following content is described in the attached SDK user guide.
    Regarding <txChannelEn> of channelCfg in 3.4

    -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ---
    The 2 azimuth antennas can be enabled using bitmask 0x5 (i.e. tx1 and tx3)

    The azimuth and elevation antennas can be enabled using bitmask 0x7 (i.e. tx1, tx2 and tx3)
    -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ---

    Is it okay to recognize that tx1 and tx3 can only be used as azimuth antennas and tx2 can only be used as elevation antennas in AWR1843?

    Hi, thank you for answering the question.

    Is the mmWave Demo Visualizer also used to configure the AWR1843 configuration instead of the AWR1843EVM?

    I think what you taught me is when writing settings to EVM.

    Hi,

    All three antennae, tx1,2,3 can be used for azimuth when using MIMO configuration in order to increase the angular resolution.

    So, it is not correct to say that only tx1 and tx3 can be used for azimuth. The documentation in C:\ti\mmwave_sdk_03_05_00_04\docs\mmwave_sdk_user_guide.pdf is not 100% accurate.

    Regarding configuration, here are the steps used by the mmWave SDK demo. Please note that this can be implemented differently in other demos.

    Step 1 Configuration Parameters

    Configuration Parameters are defined either using the Visualizer or in a configuration file (similar to the ones provided in C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\profiles)

    Step 2 Sending Configuration Parameters to the Application Code running on Target

    The Configuration Parameters are sent through the User Application UART to the Application running on the Target

    Step 3 Application Use of Configuration Parameters

    The Application running on Target will use some of the parameters to configure the RF front end and other parameters to configure the application demo.

    Thank you
    Cesar

    Thank you for your reply.

    > Step 2 Sending Configuration Parameters to> the Application Code running on Target

    Does this mean sending it with the Visuarizer's [SEND PC] command?

    Yes, the visualizer will send the configuration paramters to the target. Either by loading them from a configuration file or by generating them on the fly from the parameters input in the visualizer gui (range ...)

    thank you
