Hey all,
For the second time in my career as a tech/junior engineer, I had a board today that randomly failed mid test. Checking multiple times and it was as if all the code just stopped. This particular example was audio related and the sound went all garbled for a few seconds then vanished. The microcontroller in this example is related to the audio.
We reprogrammed it and the code took and all of a sudden everythings working fine.
Anybody have any plausible explanation? The weird thing was the board wasn't even being handled when it broke. We were just sitting a few feet away talking and it died. The audio portion was running and hearing us talk so the code was being used when it died, its just I'm much more familiar with things breaking when you touch them than just randomly. Also nothing was even remotely hot, that was the first thing I checked almost immediately to try and catch before things would have cooled.
