TMS320F28379D: FreeRTOS Integration

Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hi, 

I imported the Demo project from this path Kernel > FreeRTOS > Demo > C2000F2838x_C28x_CCS, and used the syscfg tool to switch the processor to F28379D LaunchPad by following these steps: https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1013265/tms320f28379d-cannot-change-the-device-value-to-28379d-in-ccs-project-with-project-properties-and-sysconfig. However, the project still doesn't run correctly.

Example Project Imported: freertos_ex2_c28x_led_blinky_syscfg

The code gets stuck here: 

 

Is there any other way I could use FreeRTOS with this board, or are there any steps I'm missing in changing the processor for this project?

Thanks

    Hi Aashika,

    Apologies for the delay. Unfortunately, the FreeRTOS demos are not compatible with SysConfig-based migration. So, I would suggest creating a new project for F28379D.

    You will need define a linker cmd file for the F28379D device with appropriate sections for FreeRTOS (You can refer to the cmd file at [C2000Ware]\kernel\FreeRTOS\Demo\C2000_F2838x_C28x_CCS\). All other FreeRTOS files remain the same and can be imported and used directly.

    Thanks,

    Arnav

    Hi Arnav,

    Thank you for your response, I imported the single core blinky project for F28379D and included FreeRTOS from syscfg, however I was running into this issue:

    But then I combined all sections of the LS RAM in the cmd file and replaced this in the .text section as shown below:

    Original:
           RAMLS0           : origin = 0x008000, length = 0x000800

       RAMLS1           : origin = 0x008800, length = 0x000800

       RAMLS2           : origin = 0x009000, length = 0x000800

       RAMLS3           : origin = 0x009800, length = 0x000800

       RAMLS4           : origin = 0x00A000, length = 0x000800

    .text            : >> RAMD0 |  RAMLS0 | RAMLS1 | RAMLS2 | RAMLS3 | RAMLS4,   PAGE = 0


    Replaced with:

       RAMLS_ALL        : origin = 0x008000, length = 0x002800

    .text            : >> RAMD0 |  RAMLS_ALL,   PAGE = 0


    After this, I was able to build the project with FreeRTOS successfully!
