Live Q&A - How to Detect Anomalies in RTOS Applications
Dr. Johan Kraft - Watch Now - Duration: 17:45
12:44:32 From Jean Labrosse : What are the latest features in Tracalyzer? It looks like the product evolved. 12:44:46 From Leandro Pérez : I have noted the trend of the SMP microcontrollers… the Tracealyzer for FreeRTOS license permits debug this architecture with more tan 1 core? 12:49:51 From Jay Cosper : In release mode, we would log assert versus trapping 12:50:54 From Quantum Leaps : Assertions are your last line of defense against bugs... 12:51:55 From Gillian Minnehan : That makes sense, thank Aaron 12:51:57 From Gillian Minnehan : *thanks 12:52:59 From Keith J : Re Miro - some would consider asserts to be the first line of defense against bugs (other than not creating them) 12:53:00 From Jean Labrosse : I agree with Miro, assertions is your last line of defense 12:53:29 From Keith J : (not my opinion just one I've heard) 12:54:40 From Quantum Leaps : Great point: you need to *test* your assertion handler under many conditions, including stack overflow and others. 12:55:23 From Gillian Minnehan : Test your tests! 12:55:59 From Jacob Beningo : Lol how many layers of tests is too many? 12:56:11 From Leandro Pérez : Inception… lol 12:56:12 From Jacob Beningo : (Thinking of layers of indirection with poitners) 12:56:40 From Quantum Leaps : I'd say: test your assertions, meaning that you should intentionally inject errors and see if your assertions catch them 12:57:35 From Gillian Minnehan : @Quantum Leaps Agreed. Sanity check like that seems sufficient 12:57:45 From Tim Michals : It is hard to get customers to provide log information, they are worried the logs can be used to reverse engineer the way the product is used. 12:57:54 From Jean Labrosse : … assertions are fine if you can test all of them during development/test. After that, they could become dangerous to have, especially if you leave them in deployed code. However, a lot depends on the application and whether it's safety critical or not 12:58:23 From Jean Labrosse : Great talk Johan! 12:58:32 From Leandro Pérez : Thanks Johan 12:58:38 From Gillian Minnehan : @Tim Good point 12:58:41 From Aaron Fontaine : Great talk Johan. Thank you! 12:58:53 From Gillian Minnehan : Thank you Johan! 12:59:03 From Jay Cosper : thank for the talk! 12:59:06 From Keith J : Thank you Johan 12:59:19 From Stephane : Website seems to be working better now 12:59:23 From Phil Kasiecki : Thank you Johan. I enjoyed the session, and having started my career working on real-time trace systems in their infancy, seeing Tracealyzer shows how far things have come.
