F29H85X-SOM-EVM: How to run multi-core application with FLASH build?

Part Number: F29H85X-SOM-EVM

Tool/software:

Hi, experts,

Customer needs to run multi-core application from Flash. We tried with led_ex1_blinky_cpu1_cpu3_multi example.

Follow steps in user guide documentation, we can run this example with RAM build. When we try to flash the image into Flash and run from flash, it failed.

Launch a CCS debug session, connect to CPU1 and load only the c29x1.out.
After the program is loaded, run CPU1.
Once c29x1 configures and releases CPU3 out of reset, the program stops.
Connect to CPU3 target now. c29x3.out would have started execution as soon as it is released from reset.
In case of RAM configuration, restart the CPU3 target and load the symbols.
Note: For FLASH configuration, this example is run in FLASH BANKMODE2, where CPU3 has access to FLASH (FRI-2). Refer to the Flash Plugin documentation to know about changing FLASH BANKMODEs and more.
View the device LEDs blinking. The output of the GPIOs connected to the corresponding LEDs can be seen toggling.

We have already change to FLASH BANKMODE2, following description in this FAQ.

Please help to guide the detailed steps for running multi-core application in Flash. Thanks.

    Hi Fan,

    Here are a list of detailed steps for running multi-core application in Flash:

    1. Right click the target configuration and start a Project-less debug.
    2. Right-click CPU1 target and select 'Properties' from the drop-down.
    3. Change the category from 'Program/Memory Load Options' to 'Debugger Options'.
    4. In the Auto-Run options dialog box, unselect 'On a program load or restart', then click 'Save & close' for the 'Properties' dialog box.
    5. Right-click CPU1 target and connect to the target.
    6. In the taskbar, click the 'Run' option, then scroll down and click the 'Load Program' option.
    7. First, browse for the generated 'led_ex1_blinky_cpu1_cpu3_multi_c29x3.out' program file and click ok.
    8. In the taskbar, click the 'Run' option, then scroll down and click the 'Load Program' option.
    9. Second, browse for the generated 'led_ex1_blinky_cpu1_cpu3_multi_c29x1.out' program file and click ok.
    10. Press the 'Continue' button for CPU1 target to run the CPU1 application. The application should halt at an ESTOP0 instructing that CPU3 is now out of reset. 
    11. Right-click CPU3 target and connect to the target.
    12. In the taskbar, click the 'Run' option, then scroll down and click the 'Load Symbols' option. 
    13. Browse for the generated 'led_ex1_blinky_cpu1_cpu3_multi_c29x3.out' program file and click ok.
    14. Press the 'Continue' button for CPU1 target to continue to run the CPU1 application.
    15. Press the 'Continue' button for CPU3 target to run the CPU3 application.

    Note: The device must be in Bank Mode 2 in order to load for both CPU1 and CPU3 applications. 

    Thanks and regards,

    Charles

    Hi, Charles,

    Thanks for the detailed steps.

    I can successfully run led_ex1_blinky_cpu1_cpu3_multi demo in Flash following your steps.

    When customers develop their own multi-core application, how about the suggested steps? Do they also need to place ESTOP0 instructing, and run similar steps as you listed?

    Thanks.

    Hi Fan,

    ESTOP0 is not technically required, but it is better to include for debugging purposes in emulation mode. 

    Thanks and regards,

    Charles
