How to program and run C code in release...

Other Parts Discussed in Thread: TMS320F28069

I have been working with the TMS320F28069U in a development environment for a few weeks and yesterday I decide to switch over to release mode and have the code execute standalone and realized I do not know how to execute this in the tool.

1. I used the hammer icon and switched the build option to release. The program compiles with no errors or warning.

2. I use the debugger/emulator (TI XDS100v2) to load the .out file in the release directory of the project. I see the program load and execute when reset. As soon as I cycle power the program is gone and must be reloaded.

What am I doing wrong?

    Hello Brine!

    If I understand you have worked only with emulator and now you wish to run DSP in standalone mode. If it is so, then I would recommen you this manual 6153.TI_Running_from_Flash_spra958l.pdf. Check that file  F2806x_CodeStartBranch.asm is presented in your project. Selecting the active configuration (Debug or Release) does not matter in this context.

    Hi Brian,

    As Igor has mentioned... You need to run the code from flash. What you're doing is running the code from RAM which is a volatile  memory and so the .out file gets erased the moment you reset the power :)

    For running the project from flash, all you've to do is Right click on the Project -> and select Run from Flash option.

    TMS320F28069 projects havve that advantage, else you can always refer the above doc.

    Regards,

    Thanks for the reply gentleman...when I added the CodeBranch.asm file it immediately began working.

    Guatam, I couldn't find the option you were referring to in your instructions; however, I did verify in the disassembly that the main function was placed in flash and not RAM.

    Thanks again...
