Edit linker cmd file

Johannes

Hi everyone,

I want to edit the .cmd used during link phase to add a memory section like:

SECTIONS
{
my_mem_section: load >> L2SRAM
}

The problem is, the .cmd file is generated automatically, so if I edit the .cmd file manually it will be overwritten when I build my project and in the end of the build, CCS is going to show a message like this:

<Linking>
warning #10247-D: creating output section "my_mem_section" without a SECTIONS specification

How do I specify the SECTIONS if the linker.cmd file is generated automatically?

Is there other way of doing this, using CFG maybe?

Thanks for any help

Hi Joh,

Create your own cmd file for example private.cmd and add it to your project,

Thanks HR!

I created a new cmd file with just the new SECTIONS I wanted and added to the project, it just worked fine.

follow up question:

Default linker.cmd (generated file) contains .text in L2 memory. Can I redefine in private.cmd .text to DDR3? How can I define text to DDR3?

If you are using BIOS, then see SPRUEX3K Chapter 6 "Memory", in particular Section 6.2.2.1 " ... Default Memory Setting", at bottom of page 136:

Click on Code Memory (i.e. .text) and change the value from L2SRAM to DDR3. That should change the auto-generated file.
