I'm facing similar issues with enabling the the debug probes resulting into system failure. Is there anyone from WICED team here who can comment on it?
We recommend downloading SDK 3.3.1 (the latest one) and checking to see if the problem still persists.
I felt like there is problem with stack quite a number of times when I enabled the debug messages.I followed a number of times on on hard fault handlers, but could not conclude any as of now. I might actually give it a try on the new SDK.
I spent a couple of hours trying to install SDK 3.3.1 on Windows 7 and could not get it to build projects. It is pretty much a disaster, when it starts up it has java failures and it cannot build its own libraries so that you can even add projects.
