CCS/TMS320F28379D: Expression window is inaccessible in real time debug mode

Sometimes when I try to run the device in real time debug mode, I can't access to global vars in Expression window. The window shows "Target is running" for all the vars. I neither can suspend the device because the Suspend button (Alt+F8) becomes unavailable.

Is the device still running in a good state at this point (ie has not gone off into the weeds)? I am wondering since you say it is also not possible to Halt/Suspend the device.

Does it work if real-time mode is not enabled, but just the Continuous Refresh icon in Expressions view is enabled?

AartiG,
Thanks for your response.
It happens right after I click the Resume (F8) button. So, I don't know if the device is running in a good state or not. I just know that it's running since there is a LED blinking.

Disabling real-time mode doesn't help.

Normally, after I enable the Continuous refresh feature, the windows (Expression, Register, etc) start flickering when the update intervals come. For mentioned issue, I noticed that the Expression window was not flickering every update cycle, even before I let the CPU run.

And I've just found out that when the issue happens, I still can access registers in Register windows with Continuous refresh enabled. The Expression window keeps showing "Target is running" even when I disable the its Continuous refresh.

I can't seem to reproduce this. I tried a couple of examples from C2000Ware on a F28379D Launchpad and none of them exhibited this behavior.

I wonder if the issue is application specific. Would you be able to try out some example projects from C2000Ware to check if you see the same behavior?

AartiG,

I am trying with TIDM-1001. So far none of my colleagues has encountered. I will try with some other code examples and let you know next week.
