Tool/software: Code Composer Studio
Developing on the 5529LP, using USB CDC receive only and SPI (A) send only, it unpredictably freezes anywhere from < 3 minutes to over an hour after start. I didn't discover the problem until I tried simulating the final system which will be unattended. When it locks up, occasionally the evb reset button will allow a restart but most often only a disconnect/reconnect and restarting the host app will work. This won't be possible with the host unattended.
I eventually tried a pristine copy of example C1_LedOnOff and it does the same. I have a LabVIEW test routine that repeats "LED ON" "LED OFF" commands with adjustable delay time. Faster repeats (up to 50msec) seem to make the problem occur sooner but it's not consistent enough to be predictable.
This can be replicated on an out of box 5529LP board and fresh copy of C1_LedOnOff example code. Running in debug mode or downloading a release version doesn't seem to affect it at all. As a test I tried commenting out the reply communication with no effect.
Just updated to the latest CCS 1010 with no improvement, running Windows 10 on a desktop workstation.
