Marjan,

>From that code snippet the compiler will determine that both gfg and rad do
nothing (while values are assigned to them, they never appear on the rhs of
an assignment nor are they used as arguments in a function call) and so will
optimise those variables away.

Subject: [Mspgcc-users] Cannot read any variables in while debugging

Hi all,
I have a very simple code:
****************************
#include <msp430x44x.h>
/* Brute Force delay loop */
void delay(unsigned int d)
{
    for (; d>0; d--) {
        nop();
        nop();
    }
}
int main( void )
{
    float gfg;
    int rad;
    /* Init watchdog timer to off */
    WDTCTL = WDTPW|WDTHOLD;
    /* Init Output ports to GND */
    P5SEL =0x00;
    P5DIR=0x02;
    gfg=0.2*100;
    rad=134;
    /* Loop until the universe breaks down */
    while (1) {


            P5OUT ^= 0x02;
        
        gfg=5.5;
        /* Toggle P1.0 ouput pin */
       
        /* Delay for a while before blinking */
        delay(0x4fff);
    }  /* while */
}

*******************************
It compiles and it works allright (LED flashes). But when I debug with
msp430gdb, I cannot see value neither of gfg, neither of rad. I can even
determine breakpoints and step through it. I am using original Texis
Instruments FET.
BTW: If 'next' is first command in debugger after being loaded and
initialised (if program is started with 'next' command), debugger hangs
itself. And I am using Linux.

Help will be much appriciated!

Marjan
