Hello,

I am using C2000 launchpad with Digital Power Supply example project CCS v5 running. I could run debugging if "RAM" debugging mode is selected, unfortunately I need to change it to "FLASH" mode to increase code size. While changing debugging mode to "FLASH" and start "Built All" i get many error messages and stop the built. I do not understand what makes difference same code run well in RAM debugging option and not built in FLASH. I have attached error log and screen while return built error.

    Hello Rafeeq! 

    If you accurately describe the chain of events that may be a problem is in your file F28027_FLASH_myproject.cmd. Let's look at the following fact: the compiling with the command linker file F28027_RAM_myproject.cmd have not generated errors and with  F28027_FLASH_myproject.cmd compilation errors occur. Unless of course you did not change anything in the source code...First of all I would recommend you to take  F28027_FLASH.cmd from some example of controlSUITE.

    Regards,

    Igor

    Hello Igor,

    Firstly, I am not expert in CCS V5 application.

    As you mentioned I have copied one "F28027_FLASH.cmd"  from an example project, and renamed then put in my project folder.

    But unfortunately i can see same result as same error, I do not know is it because i renamed the .cmd file.

    I will uploaded the project file.  Could you please look into this ?   I am thankful to you if you give some comment in this.

    Hello Rafeeq!

    Sorry! But your project is not compiled for RAM-version too. There were a problem (error messages) at file myproject-DPL-ISR.asm (like your screenshot) in following code:

    ;call DP library modules

    ;---------------------------------------------------------
    .if(INCR_BUILD = 1)
    PWMDRV_1ch 1 ; PWM1A
    .endif
    ;----------------------------------------------------------

    I replaced the file PWMDRV_1ch.asm of your project a different version  from ti\controlSUITE\libs\app_libs\digital_power\f2802x_v3.4\asm_macros\PWMDRV_1ch.asm (2705.PWMDRV_1ch.asm). Compilation was successful.

    In addition the file myproject-Main.c had a warning at following code:

    // 60MHz/10Khz = 6000
    PWM_1ch_CNF(1, 600000, 1, 0);

    why do you set 600000?

    replace on PWM_1ch_CNF(1, 6000, 1, 0);

    This is all at now...

    Regards,

    Igor
