I build a commercially available product using a Picaxe 20M2, which has been in the field since 2013. On very rare occasions (3 times so far, out of hundreds), a customer will claim that the device has competely quit working. And it has. But, reinstalling the firmware is always successful, the device works properly, even after severe environmental stress testing, and the units appear to be fine, even many years later.
Long ago, I opened a ticket with Microchip about this, and they ultimately shrugged and mumbled about cosmic rays and bit hits.
This just happened again (the third time), and because I track serial numbers of the devices, it was interesting to note that they were all sequential serial numbers, from 2015.
Has anyone else seen this?
