as soon as someone writes the linker script and the patches to binutils
and gcc ;-) there was a post from Steve with patches for an other
target, those could be used as template.

Otherwise the the mpsgcc complains
error: timera.h: 150: storage size of 'timera1' isn't known
thanks, fixed
I have 3 problems left to port the software:
- no_init is unknown. Can i simply erase no_init in the declaration
no_init <variable declaration>
hint: __attribute__ ((section(".noinit")))
as in: int __attribute__((section(".noinit"))) var;
descibed here: http://mspgcc.sourceforge.net/manual/x987.html
or as an other posibility: http://mspgcc.sourceforge.net/manual/x1023.html
- The code has a pragma for putting some variables into flash memory:
#pragma memory=constseg(INFO) int foo = 42; #pragma memory = default
How can i port this to mspgcc?
same syntax as above but with a different section.
i think "infomem" should work for you
and "infomemnobits" would be almost the same, except that it does not
include the initial value in the elf/hex file
- The code is too big:
msp430-gcc -mmcu=msp430x413 -Os -mendup-at=main -Wall -g -c main.c
... msp430-gcc -Wl,-s,-O,--verbose -mmcu=msp430x413 -Os -o aout.elf
main.o isr.o memory.o modules.o msp430-ld: region text is full
(aout.elf section .text) msp430-ld: section .vectors [0000ffe0 ->
0000ffff] overlaps section .text [0000e000 -> 00010341] make: ***
[aout.elf] Error 1
Is there no trick to reduce the size to the size the IAR compiler
produces?
- did you compile for the same target?
- did you try -O2 too?
- does the code use floats?
