EDMA test example

Hi,

While trying to run the EDMA test, I found that I must add a 'dependency' to 

'\ti\edma3_lld_02_11_05_02\examples\edma3_driver\evm6657\rtsc_config' project.

This project generates a 'cmd' file which can not be modified. I also can't contiue using my old 'cmd' file.

How Can I modify this 'cmd' file or use my own file. ?

Thanks,

Ivgeni

    Ivgeni,

    Please go through the below wiki, it will be useful to get better understand about linker command file(.cmd).

    http://processors.wiki.ti.com/index.php/Files_in_CCS_Projects#Linker_command_files

    1. If your board has a different memory configuration you may need to edit the files. In this case, carefully inspect the MEMORY and SECTIONS directives.

    MEMORY defines names for physical memory address regions
    SECTIONS assigns each piece of code or data to a MEMORY name

    2. These files do not define a size for stack and heap memory, thus requiring you to specify their sizes using the linker options --stack_size and --heap_size.

    3. Where applicable, these files allocate all SECTIONS to Internal RAM. Depending on your application the space may be insufficient. Please modify the files accordingly to move large SECTIONS to External RAM but don't forget you will have to properly initialize it with a suitable GEL File for your board (provided by your board manufacturer).
