Hi All,

Is there a way to use values from the linker.cmd file in a C program?

Such as the .xStack ORIGIN and LENGTH values.

Thanks,
Pete

Hi William,

Thanks for the reply.

I was hoping there was a way to directly use the values entered in the MEMORY section.  I do something similar to what you are doing with constants but sometimes I forget to change both values.  Maybe I just need a better "memory".

Thanks,
Pete

There might be better ways, but here is an example ...


MEMORY

.xstack  (RW)  : ORIGIN = 0x0040, LENGTH = 0x0300  # stack
...
.custom (R)   : ORIGIN = 0x2000, LENGTH = 0x0010  # custom stuff from this file

SECTIONS
{
...


  .information :

     _STACK_ORIGIN = 0x40;         # constant from MEMORY declaration above
     _STACK_LENGTH = 0x300;        # constant from MEMORY declaration above
     WRITEH( _STACK_ORIGIN );
     WRITEH( _STACK_LENGTH );

          &nbs p;   #
              # Make the custom variables global
              # and accessible from "C"
          &nbs p;   # under the same name w/o the leading "F"
              #
   Fstack_origin = ADDR(.information) + 0;
   Fstack_length = ADDR(.information) + 1;
...
}
