MSP430G2231: Break at address "0xf822" with no debug information available, or outside of program code

Ah hyun Noh

Part Number: MSP430G2231

First of all, thank you for having interest of my thread..

I'm studying Microcontroller with MSP430G2231 IC which is quite old-fashioned.

I tried to apply a simple below code. (LED blinks normally and stops when button pushed)

int main(void)
{
    WDTCTL = WDTPW | WDTHOLD;  
    
    P1DIR |= 0x01;  
    P1DIR &= 0x08;  
    P1REN |= 0x08;  
    P1OUT |= 0x08; 

    for(;;)
    {
        volatile unsigned int i;
        P1OUT ^= 0x01;  
        i = 50000;  
        do(i--);
        while(i != 0);

        while(!(P1IN & 0x08));
    }

    return 0;
}

At 'Build Project' process, Console prints below warning messages, but build was completed somehow.

At 'Connect Target' process, the error message occurs.

Here's the disassembly code of pointed address, "0xf822".

Did the error occur just because the MCU IC is too old to be applied recent-version software?

Or is there any problems? If there is, can the problems be solved by interpret disassembly code above?

Hi,

Does the code function is normal?

Thanks!

That location is pretty clearly within the C runtime. The reset vector points here.

So the location is outside of your code but still within the program.

Hi, Jonnson!

Thank you for replying my post.

Sorry but I'm afraid that I can't understand what does 'function is normal' mean..

Just to be safe, I executed same process without code, but the same problem still occured.

Thanks!

Sincerely,
Ah Hyun

Hi, Zain!

Thank you for replying my post.

I checked the link you sent, but the error message was differenct with mine.

Thanks :)

Hi David!

Thank your for replying my post.

I searched the disassemble code where the compiler breaked at

And I found that "4031 0280" stands for "ready to send to the flash memory"

So I guess compiler met the error when it tried to connect memory.

But I don't know what should I do to solve this..

Thanks.

Hi,

I means that if the function is normal?

Have you use our example code? or design by yourself?

Thanks!

Hi,

at first, I used the code I learned at lecture.

But after met the error continuously, I tried this with TI's example code from resource explore as well.

And it failed in the same way after all...

Thanks!

Hi,

I think this just occur in debug mode, and like previous David's comments.

That location is pretty clearly within the C runtime. The reset vector points here.

So the location is outside of your code but still within the program.

Thanks!

Hi,

Yes, we are on the same page.

No matter what code I use, the error comes up every in 'target connecting' process after completed build process.

There must be a problem in connecting between CCS and target board.

But I don't know what it is exactly is, and how to solve as well..

Thank you :)

Hi Ah,

I don't think this is a hardware issue, maybe you can try other example to check if all code will encounter same issue.

And looks the function is normal, thus this should have some debug issue or some other software issue here.

I can try to run your code when I get the lanuchpad.

Thanks!

Best Regards

Hi Johnson,

It's resolved. It was a debug issue.

Thanks for helping me :)
