Greeting Dr. Martin G. My guess is that optimization is causing problems with your debugger sessions. I use these compile and link flags on the windows platform (msp target). I think the -g is important in this respect.
These are the flags I have used in the past. +++ CFLAGS= -save-temps -g -DMSP430F133 -mmcu=msp430x133 -mendup-at=main -Wimplicit-function-declaration -Wall -W -Wno-char-subscripts LINKFLAGS= -Wl,--print-map -Wl,--cref -Wl,-Map=map.txt -Wl,-T .\msp430x133.x +++ Cheers, Jody Baudoin -----Original Message----- From: [email protected] [mailto:[email protected]]on Behalf Of Dr.-Ing.

I'm able to compile load and run programs but using the debugger (GNU gdb 5.1.1) does not work as expected. When I compile and link the following program: #include "io.h" #include "signal.h" static uint16_t sum(uint16_t a, uint16_t b) { uint16_t s = a + b; return s; } int main(void) { uint16_t s; /* Disable watchdog during initialization */ WDTCTL = WDTPW|WDTHOLD; s = sum(1000u, 400u); while (1) { /* Enter Low Power Mode 3 */ LPM3; } return 0; } with: /usr/local/msp430/bin/msp430-gcc -mmcu=msp430x149 -g -c simpletest.c -o simpletest.o /usr/local/msp430/bin/msp430-gcc -mmcu=msp430x149 simpletest.o -o simpletest When I step into the function sum and look for the function arguments the debugger prints: p a $1 = 1400 p b $2 = 16383 The sum s however gets calculated correctly. p s $3 = 1400 I would be very happy if someone on this list could give me a hint what I'm doing wrong since the application I 'm actually developping does not behave as expected and I need a reliable debugger to solve the problem. My application uses some rather large structures so there may be a memory problem. Does anybody know how to check if sufficient memory is available.
