TMS320F28377S: Use CMD file section variables in c code

Onzino,
That is the general information about CMD a need details.

A want to do this:
((void (*)()) codestartAPP) ();

adding this:
extern uint32_t codestartAPP;
I still got onresolved symbols.

So what do I have to do codestartAPP is defined in my c code?

So why does work ?
// Copy time critical code and flash setup code to RAM. This includes the
// following functions: InitFlash();
// The RamfuncsLoadStart, RamfuncsLoadSize, and RamfuncsRunStart symbols
// are created by the linker. Refer to the device .cmd file.
memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize);

But not for my definition?

thanks,
EVS

EVS,

Have you included the header files were those definitions are defined? There is this document that details how to define and access defined sections. processors.wiki.ti.com/.../Linker_Command_File_Primer

Ozino,

I don't know if this is what you are trying to tell. But what I needed to know is you can use  preprocessor  commands in the cmd file.

Thanks,
