You'll want to specify the processor when compiling and linking. msp430-gcc -mmcu=xxx main.o -o main.elf
replace xxx with the processor that you are using like msp430f149 There are linker scripts to tell ld (invoked by gcc) how to link and where the vector table goes, where rom starts, rom starts, etc. adam -----Original Message----- From: Ian Chapman [mailto:ichap...@videotron.ca] Sent: Thursday, October 04, 2012 1:42 PM To: mspgcc-users@lists.sourceforge.net Subject: [Mspgcc-users] Linking problem I'm using the PCB from TI with the msp4302211 packaged in a 14 pin DIP. My msp430-gcc --version from Mint13 is msp430-gcc (GNU GCC patched mspgcc-20110716) 4.5.3 I have made a small "c" program to get into the swing of it and that loaded into 0xf800 with mspdebug ran the way I expected. Trying the same thing with assembly code was and is quite frustrating. The part has 2K of flash and I guess it's 0xf800 to 0xffff. .org 0xf800 ;gives assembly errors. msp430-as -Wall -mP main.s -o main.o main.s: Assembler messages: main.s:47: Error: operand out of range: -63126 main.s:48: Error: operand out of range: -41834 main.s:48: Error: operand out of range: -63130 Junking the org directive but keeping the .org 0ffe0 ;For my interrupt vectors The assembly was clean creating a main.o and a listing. Linking with msp430-gcc main.o -o main.elf /usr/lib/gcc/msp430/4.5.3/../../../../msp430/bin/ld: main.elf section `.text' will not fit in region `rom' But no main.elf !!! If I junk my interrupt vectors oxffe0 then assemble and link I get a main.elf. Using mspdebug I can prog it and it went into 0xfc00 (NOT 0xf800 as expected) with a bit of stuff that's not mine up front. Of course I'm not able to run it as I do not have any interrupt vectors. Any pointers greatly appreciated. I've played with .fartext to no avail.
