Program does not halt on set breakpoint

ISHAN SHAH1

Other Parts Discussed in Thread: CONTROLSUITE

Hi I am using C2000 Launch Pad. and using CCS 6.0.1

I have simple code for ADC read and PWM. 

In CCS debug mode, I have set few break points in the code and in the breakpoint properties the action is set to  "Remain Halted". My assumption is whenever program counter will reach the break point, the code will stop executing at that point unitll the I click the run button again, but the code keeps on running. I know code reached the break point since I can see variables updating in the watch window but the code does not stop at that point.

Please guide me. What I am doing wrong.  How do I use breakpoints, so that code stops executing, where breakpoint is set. 

Many Thanks,

Ishan

    Are you able to set atleast one breakpoint?

    Hi Gautam,

    Thanks for replying. I am able to set breakpoints at many places by double clicking on the side bar, but the problem is  program does not halt at the set points. 

    I have tried both hardware and software breakpoints. In the break point properties I have clearly set as remain halted. 

    is it something to do with C2000 launchpad capability or CCS thing ? 

    Thanks,

    Ishan

    I think what Gautam mean is, if you put one breakpoint only, does it work (halt) or not?

    Please remove all the remain breakpoints, and put only one breakpoint. Does this breakpoint work?

    Best regards,

    Maria

    Hi I tried putting just 1 break point it did not work. 

    But fortunately I think I found the problem . 

    In the debug configurations, under the Target settings. 

    I unchecked the " Disable all the breakpoints when loading a different program " button and now the break points work just fine. 

    Many Thanks,

    Ishan

    I have the same problem with breakpoints. I am running a simple code to toggle an LED on and off.
    I have a variable called "count" in a loop that toggles an LED on and off.
    I set a breakpoint next to count, in hopes that each time through the loop the code would stop at count, where the breakpoint is. Instead, the code runs continuously, and in my expressions window I can see count increasing, and my LED continues to flash (meaning the code is successfully executed).

    I made the menu setting above:


    "
    In the debug configurations, under the Target settings.

    I unchecked the " Disable all the breakpoints when loading a different program " button and now the break points work just fine.
    "

    but my code still does not stop at the breakpoint.

    Can anyone suggest another way to make sure breakpoints work?

    Are you running the code from RAM or Flash? When you set the breakpoint, do you get any message in console window? If you can post the snapshot of CCS project view after setting the breakpoint, it will be helpful

    Attached is a screenshot of my workspace.

    I have gotten this to work now.

    This is what I did, which didn't work:

    I would set a software breakpoint, debug the code, and then not be able to pause/resume the code at the single breakpoint I had.

    This worked:

    I debugged the code, and then after debugging, I set a breakpoint in the code, and I could pause the code at the single, and then multiple breakpoints.

    I am not sure how I know if the code is set to flash or ram though. How do I know this?

    Good to know you got it working. Look like you are loading the code into Flash but running from RAM which means during runtime code gets copied into RAM and then get executed. In this case if you set the breakpoint upfront then it'll not work because breakpoint info get lost during copy code so you need to set the breakpoint after copy code is done (like you did now).

    How do you toggle between running the code in flash versus running the code in RAM?

    If you are using one of the examples from controlSUITE then you should be able to select the build configuration by right clicking on project and then clicking on options as shown below.

    I am using Properties > Debug > Flash settings to try different options for how my program is stored on my LaunchPad

    Thomas,

    I am not sure how far you have gotten with this. The Properties -> Debug -> Flash settings is for options when CCS is flashing the device. Where the code is placed is controlled by your linker command file (.cmd). Vivek was referring to the fact that controlSUITE example projects often have RAM and FLASH configurations. A configuration can have different sets of source files. In this case they are using it to have a linker command file that places the code in RAM for one config and in FLASH for the other. controlSUITE contains a lot of example linker command files that you can use as reference. You can import one of the examples that matches the device you are using if you want to compare linker command files. Both of the linker command files will show up in the project but one will be "excluded" based on the configuration that is being used.

    Thomas,

    If you still facing issue, I would suggest to start a new post because this post was already closed and closed posts are not tracked hence may not get response for long time.
