RE: HELP with target.ld file syntax...SOLUTION


Another way of doing it is altering the architecture .ld file (e.g.
hal/arm/arch/current/src/arm.ld) and add a

#define SECTION_ram2(_region_,  _vma_, _lma_)

part. You can then include this in your mlt_xxx.ldi file so target.ld will
always be generated properly. The MEMORY part is already in the mlt_xxx.ldi
file.

There may also be a way to do it like this specifically for a platform but I
haven't figured it out yet.
