DS-5 debugger does not show uC-OS info

lee morse

When starting up the debugger (v5.22), I select the uC-OSIII OS in the configuration.  When I stop in a task on a breakpoint, the OS tab has no information for any of the tables.

Is there some extra linkage that needs to be setup to get this feature to work?

    Hi Lee,

    Thanks for that - something definitely looks wrong here, the symbols appear to have been correctly loaded and the OS appears to have finished initialization, but the debugger thinks it hasn't.

    I have a number of follow up questions:

    • Do you see any errors in the Commands view? Do any errors come up in the Error Log (it probably isn't open by default, "Window | Show View | Error Log" will open it)?
    • What version of uCOS-III are you running? The command "print OSDbg_VersionNbr" will give the version number if you don't know (I see 30401 for our images, corresponding to v3.04.1).
    • Could you try printing some task information, e.g. "print OSTCBCurPtr->NamePtr" (or just "print OSTCBCurPtr" if that doesn't work)?
    • When is the startup task being run? Is this a normal OS task, or is this being run before/during the OS initialisation? It shouldn't really matter as long as 'OSRunning' is set to 1 (which occurs after the call to 'OSStart(...)'), but it will help me reproduce the issue.

    Thanks - best regards,

    Jon
