Hi,

Here is the link on Linker Command file:

software-dl.ti.com/.../sdto_cgt_Linker-Command-File-Primer.html

The example you can find in C2000ware example at :

C://ti/c2000/C2000Ware_3_02_00_00/device_support/f2806x/examples/cla/asin

You must declare these functions in cla main file as extern. Please try example to get familiar.

//
// These are defined by the linker file and used to copy
// the CLA code from its load address to its run address
// in CLA program memory
//
extern Uint16 Cla1funcsLoadStart;
extern Uint16 Cla1funcsLoadEnd;
extern Uint16 Cla1funcsLoadSize;
extern Uint16 Cla1funcsRunStart;
extern Uint16 Cla1Prog_Start;

thank you

and i am confused that RUN_START, LOAD_START,... directives will generate global symbols with
the specified names for the corresponding addresses

and use this symbol for memcpy() function, is that correct ???

Please refer to the link I provided earlier which explains linker command file in details. Go to section "Load at One Address, Run from a Different Address". it explains with an example.
