Soft-Errors

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.
