Hello,

I am trying test a default program for the LAUNCHXL-CC26X2R1 Launchpad and I am getting the following build output error.:

    Hello Johnathan,

    What default program are you trying to flash to the device, are you sure you are using the "default" program for the CC26x2, and not the CC26x0?
    It looks like you are having problems with your linker command file, have touched this file?

    Regards ,

    AB,

    I am trying to load the default BIOS/RTOS project:

    File->New->CCS Project

    In the "Project templates and examples", SYS/BIOS->Kernel Examples->TI Target Examples->Typical was my choice of template.

    Then I tried to build.

    I checked the Properties of the project and it is attempting to compile for the CC2652R1F chip which is the one on my launchpad. So I believe the default program is for the CC26x2 variant. Let me know if I need to do something else to verify which chip I am programming for.

    If the linker file in the ".cmd" file, I have not modified it. I have been modifying the app.cfg file though to try and get it to work.

    Thanks for responding so quickly!

    Hi Johnathan,

    I would recommend trying either the 'portable' project or the 'empty' TI-RTOS project for the CC26X2 SDK to confirm you have a working toolchain to get started.

    The portable project has either a POSIX API or native TI-RTOS API version available on dev.ti.com:

    All of these projects are available within the same directory location inside the desktop version of CCS within the TI Resource Explorer View.

    A great getting started guide for working with the CC26X2 SDK and project generation can be found inside the TI Drivers Project Zero SimpleLink Academy. SimpleLink Academies are detailed walkthroughs/training series on a variety of topics with step-by-step hands-on instructions.

    Please let me know if you can get one of these projects to build successfully!

    Best Regards,

    Mark-

    Hey Mark!

    Thanks for the help!

    There were two problems:

    The first was that the empty project you provided with the TI-RTOS Drivers option was the project I needed. However, it did not work initially. But that was because of problem number 2 which was that I needed to install the SimpleLink CC26x2 SDK. I thought I had downloaded it before but apparently not. Then I imported the project and compiled and it worked! I was able to load the program onto the board and get the LED to blink. 

    Thanks so much!
