xds100v2 recovery

Hi Jon,

yes, we have seen that CCS does not like when the debug connection is broken ... by sleep mode, disconnect etc.  During debugging there is constant communication with the chip and associated timesout and issues if this gets cut.  Are you encountering a specific issue?

Hi Lisa,

Well it's just that if I get called away or take a phone call and the pc goes to sleep it kills the debug session.
Yes I could set the PC up not to go to sleep; but that isn't very environmentally friendly.
I was hoping there was a "fix" available; or, at least, one in the offing.

Ciao,
Jon

Hi Jon,

I am trying to dig further into this for you.  As sleep mode ususally involves shutting the PCI and /or USB bus in many pcs, I am not sure how much can be done to save you from a disconnect.  What might be interesting to see is how CCS handles such a disconnect.  Would you be able to describe the behaviour you are seeing in a bit more detail?  What exactly do you experience recovering from sleep mode?  Do you get a hang?  Do you need to restart the debug session? CCS?  Your workspace?  Are you able to reconnect right after? 

Best Regards,
Lisa

Lisa,

Interesting questions. Here is the  entire "Console" after logging back in after waking up.
The last note is pretty much what it takes to get going again.

Hi Jon,

what I am going to do is file an enhancment request for CCS to handle sleep mode more gracefully.

Lisa

Lisa,

Thanks; that will help us all out.

Jon

Hi Jon,

no problem.
