Do you have ever heard about Soft-Errors? No, I do not mean
Software-Errors. That's something completely different. I mean Soft
in difference to Hard. I first time get into contact with
Soft-Errors in late 2011 as we have observed a spontaneous reset
within a customer's appliance. There was no indication for a
reset-request, the system simply resetted. Within some industries
this is no case to be worried about. But in that time, in that type
of industry, with this particular customer it was a challenge to
find the root-cause of this spontaneous reset. And it was even more
complicated to approve this root-cause. In this episode it is
Michal Lewczyk joining us. Michal is one of the very seldom
specialists available for Soft-Errors. Michal was one of my
colleagues in 2011 and the years after. He was the main
investigator for all Soft-Error issues we suspected. Michal has a
deep knowledge in bare metal SW-programming. He's mainly engaged
into developing software for Digital Signal Processors; thus he's
not only an elaborated and experienced software-engineer, but also
a great investigator and marvelous bug-hunter. Let's enjoy the
engineer's talk with Michal Lewczyk about one of the most quirky
phenomenon in Embedded Systems.
