CCS/TMS320F28335: Run flash boot, RAM boot, Memory mapping

Z
Intellectual 350 points
Part Number: TMS320F28335


Tool/software: Code Composer Studio

MemoryMappingQuestion.zip

The code runs well in RAM boot mode. The code is modified to boot from Flash.

the following codes are inserted to RAM code:

These three definitions are inserted before main{} 

// These are defined by the linker (see F28335.cmd)

extern Uint16 RamfuncsLoadStart;

extern Uint16 RamfuncsLoadEnd;

extern Uint16 RamfuncsRunStart;

//extern Uint16 RamfuncsLoadSize; 

//These code are inserted after initPieVecTable();

// The RamfuncsLoadStart, RamfuncsLoadEnd, and RamfuncsRunStart

// symbols are created by the linker. Refer to the F28335.cmd file. 

//   memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadSize);

memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (Uint32)&RamfuncsLoadEnd); 

// Call Flash Initialization to setup flash waitstates

// This function must reside in RAM

   InitFlash();

When build the project, it gives the memory violation messages, as the following.

My two questions:

1. memcpy() is a wrong function name. the right name is memcopy(). However, system does not recognize the right name memcopy. Why?

2. What is the violated in mapping the memory?

Thank you.

    I think you got two cmd files active within the same project. Did you change active Build Configuration? If so make sure *.cmd's for inactive configuration is grayed out checking Exclude from Build. (Right mouse click on file).
    If still error, perhps 2nd cmd file is specified in linker settings.

    Hello

    The correct name is memcpy().
    As EK mentioned, you likely have two linker command files active. Remove or exclude one from your build configuration.

    Best regards

    Yes, Thank you for the comments. I found out that is because the linker command file "28335_IQmath_lnk.cmd" is conflict with another linker command file "F28335.cmd". 

    I comments out the conflict linker command file sections in the linker command file "28335_IQmath_lnk.cmd", whihc is confict with another linker command file "F28335.cmd".here is both linker command files: 1. 28335_IQmath_lnk.zip

    4571.F28335.zip

    the error message is shown below.

    the errors show that there is not enough space for IQmath. How come?

    Hello

    You should just remove one of the linkers from your project entirely, you don't need both.

    Here are some wikis to help with linkers and your question:
    processors.wiki.ti.com/.../C28x_Compiler_-_Understanding_Linking
    processors.wiki.ti.com/.../Linker_Command_File_Primer

    Best regards
