Setting breakpoint when target is running

AartiG
Guru**** 173310 points


With CCS v4 I am unable to set a breakpoint when the target is running. This worked well in CCS 3.3.

This was reported by a customer and I verified it on a F28335 eZdsp. To duplicate, load code onto the target, run and then try to set a breakpoint which you know should be hit (like inside a ISR). This works in CCS 3.3 but in CCS 4 it doesn't even allow setting of the breakpoint.

Is there a reason for this behavior, or a different way to do it that I am missing, or is it a bug?

Thanks

    The reason for the behavior is that setting a breakpoint is an intrusive behavior when doing stop-mode debug.  That is, to set the breakpoint CCS is required to halt the target, update the opcode, and then start it running again.  In CCS 3.3 this was all done behind the scenes and most people never realized what was happening.  A similar story holds for refreshing a memory/watch window at run-time.  This intrusive behavior could cause serious issues since it would destroy real-time behavior (momentarily).  That's why we no longer do so, i.e. could be dangerous when controlling a motor or power supply.

    I believe if you're in real-time mode that you can do this.  At one time there was talk about making real-time mode the default debugging mode.  I believe they were having a hard time with the implementation.  Perhaps someone from the team can provide an update.

    The plan was not to support realtime mode by default, but to allow non-intrusive accesses while running without having to explicitly enable realtime mode (which has other consequences on the operation of the target).  Someone from emulation should be able to give a more precise date, but the soonest I've heard of is CCS 4.2, and then only for some targets.

    As for the original question, there is an option to halt the target before an access is made.  If that's enabled, then the same behaviour that existed in CCS 3.3 will take effect (ie it will appear to be possible to refresh and set/clear breakpoints while running, but in reality the target will be halted briefly each time).  If your application does not have realtime constraints, this might be acceptable for you.

    Hi

    (CCsv4.1.2)

    I've been able to set breakpoints when the target is running by enabling Target->Debug -> select Target tab -> Realtime Options -> check "Halt the target before any debugger access".

    Then relaunch for the change to take effect.

    Seems to work.

    Cheers

    This no longer seems to work on CCSv4.2.4. (or maybe this is an issue related to the Spec Dig XDS560v2 STM)

    Eddie,

    The option still exists in 4.2.4 and I've verified it works.  Please make sure the option is still set in your install.  After a launch, go to Tools->Debugger Options->Generic Debugger Options, then scroll down to the "Realtime Options" group and select the first check box "Halt the target before any debugger accesses (will impact servicing of interrupts)".  Assuming it works, you can select "Remember My Settings" at the bottom to keep it set for that core.

    Don't forget that options are per-core.  If you have a multi-core device, or use several different targets, you'll have to set it globally (Window->Preferences->CCS->Debug->Debugger Options->Generic->Halt the target before any debugger accesses (will impact servicing of interrupts)), or go through the above procedure for each core.

    Hi,

    the "Halt the target before any debugger accesses (will impact servicing of interrupts)" check box has moved to Run->Debug Configurations->Target->Auto Run and Launch Options->Realtime Options in CCSv6, right?
    I checked it and restarted CCS, verfified the box is still checked and then started debugging. I still cannot set breakpoints while the target is running (InCircuit Debug Interface as well as XDS100v2).
    The error message is "Error enabling this function: Target Access Failed". Any ideas?
    My target is a TIVA TM4C123x MCU.

    Best regards,
    Julian

    Julian,

    Could you collect a debug server log (http://processors.wiki.ti.com/index.php/Troubleshooting_CCSv6#CCS_Diagnostic_Logs) of this?  Ideally, start the logging after the target has started running but before you try to set a breakpoint.

    Julian,

    You are running into SDSCM00050528 which is fixed in 6.1 (to be released in February).

    Because the location is in flash, CCS sets a hardware breakpoint instead of a software breakpoint. It's supposed to be possible to set hw breakpoints non-intrusively while running on the tivaC, so no halt is issued. However, this is broken in 6.0. In 6.1 you'll be able to set hw breakpoints without this option set at all. In the mean time, you'll have to manually halt the processor to set any breakpoints.

    Darian,

    nice to hear a fix is already in progress. I'll try again when CCSv6.1 is released.

    Glad I came across this... as I am encountering the issue too. Extremely annoying bug! Do you have an estimate for when the patch will be available? Thank you,

    Jason - 6.1.0 is scheduled for the end of February.

    Thanks

    Would this happen to be related to a problem I've seen a few times now where clearing a breakpoint removes it visibly from the IDE and breakpoint list, but the debugger continues to hit it until you reset the board? Next time it happens I'll try to see if I can learn anything more about it.

    I searched for SDSCM00050528 and only came across the post where it was added. Can customers get access to the bug tracker where these are stored?

    Thank you,

    Yes. Check out the last line in my signature. It is a link to the public bug tracker.

    Hi,

    I just tried with CCSv6.1 and it works for both InCircuit Debug Interface and XDS100v2.
    The "Halt the target before any debugger accesses (will impact servicing of interrupts)" box does NOT have to be checked to make it work.
