Linker .cmd files

Odd Trandem

I'm trying to build a project for the C6678 having configured for using some SYS/BIOS task, semafore etc. and some basic NDK functions included by using the graphic .cfg editor.

Everything compiles, but I am not able to link the project. I have made my own linker command file, I want to control which section is loaded where in memory, but somehow the linker gets additional input from a file ./configPkg/linker.cmd file, so my memory definitions clash with definitions in that file. This linker.cmd file have a header:

/*
* Do not modify this file; it is automatically generated from the template
* linkcmd.xdt in the ti.targets.elf package and will be overwritten.
*/

so I'd better not edit this file.

So my problem is, how to get rid of usage of this file, or how can I control the content of this file?

I found a description in the help menu that tells how to configure memory and give section names through the

(Debug view) Tools -> RTSC tool.->platfororm -> Edit/ View or -> New menu.

But I could not figure out how this could be used to make difference between the CPU cores.

And I am confused how this is related to the the video explaining how to configure memory for different cores:

Odd,

You may want to have a look at this documentation: Memory Management especially the "Controlling the generated linker command file" section at the end of the documentation.

Hope it helps.

Odd,
here is another thread you may want to check http://e2e.ti.com/support/embedded/bios/f/355/t/145752.aspx. It deals with C6472, but the answers apply to C6678 too.
