MCUXpresso Very Slow while Debugging

[pcpro178]

Today, I noticed that MCUXpresso is very slow while debugging.  For example, single stepping now takes at least 10 seconds, longer if stepping over a function call. Any clues on how to fix this would be great.

Hi Jim,

which views do you have open? For example if you have the FreeRTOS task list (or other views) open, they will need to get data from the target which can slow down things.

The other thing I have noticed (not MCUXpresso, but Eclipse in general) is that sometimes virtual machines and their network drivers can slow down any network communication (which is used by the debug probes, btw).

Or firewall software which check things on the internet for every network access.

I hope this helps,

Erich

I closed a bunch of unused views and followed the instructions at this link to increase the memory available to the IDE, and the problem seems to have cleared up.
