    Hello Herbert,

    Have you verified whether they are programmed correctly in Flash and get correctly copied into RAM? Can you verify that the memory which should be getting executed is not overwritten at the time the function is called?

    So when you look at the Memory Browser window you are able to see all the functions in their proper location in RAM/Flash, correct? Do the functions which aren't running ever get executed even once (please check with breakpoints)? Does the program get stuck somewhere in code or is it able to execute fine in some while loop at the end of main or something similar?

    I'm sorry, I don't know what you're asking for here. Are you trying to look for example code?

    help check if it is ok as this Function definition :

    #ifdef __cplusplus

    #pragma CODE_SECTION(".TI.ramfunc");

    #else

    #pragma CODE_SECTION(所需函数, ".TI.ramfunc");

    #endif

    TMS320F28027 has  memcopy function , but 2800137 can not find it , 

    if it is as above funtion definition ,thks

    If you're using the second pragma statement then yes it is correct, as long as a valid function is used within the statement.

    You can use the memcpy function found in string.h, this should work fine.
