Read the section "Using the linker command file"

 

use #pragma SET_CODE_SECTION() for code

 

I think that will work.

thanks oPossum, that got thru compile. on to all the linker flags, etc, etc.

how there should be a way for CCS inline to access variables defined in 'C', i suppose?

 

when i tried,

 

    union u_data r12_val;
    uint16_t data16;


#ifdef MSP430
    asm(" mov r12,%[res]": [res] "=r" (r12_val.w);
    asm(" mov r13,%[res]": [res] "=r" (data16);
#else
    asm(" mov r12,r12_val.w");
    asm(" mov r13,data16");
#endif

 

CCS complain it can find the variables "r12_val" and "data16".

 

i google a bit and was told inline assembly cannot access variables on the 'C' side.

 

any easy way? hints?

You can access global variables, but not local. You must also specify addressing mode.

 

   asm(" mov r12, &r12_val.w");   asm(" mov r13, &data16");

 

 

Really best to write functions completely in assembly (in a .asm file) rather than use inline.

right. one step at a time for me.
