Your organization can get to market faster with higher-quality products when given better insight into the “dark side of the code”—the actual behavior of the full software system. Intended and actual behavior may differ in myriad ways that are not apparent from the source code
The real test of IoT devices comes after shipping, when thousands of end users start using your product, sometimes in unexpected and untested ways. No software is entirely bug free, so some users will run into those remaining bugs. The question is how many and what you do about it.

A clear indication that you may have a deadlock problem is when multiple tasks suddenly stop executing, although no higher priority tasks are running.
The central idea underlying an RTOS with a fixed-priority scheduler is that a high-priority task should be scheduled ahead of one with lower priority. Yet, as a developer you have to watch out for programming pitfalls that can result in inverted priorities.
When you have a task in your system that is supposed to execute at regular intervals, say for instance that it needs to read a sensor value every 5 milliseconds, then you have a system that is sensitive to random delays – also known as .jitter.
In embedded systems using multitasking, you may run into a situation where some of your tasks run slowly or not at all. This is called task starvation (the affected tasks are starved of CPU time) and it can happen for a number of reasons.
Percepio exhibited at the Embedded Vision Summit in May, and the show hosts were kind enough to come to our booth and ask for a quick presentation of Tracealyzer and its support for the OpenVX vision programming framework. We were happy to comply; watch the video here to hear what our CEO [...]
There is no doubt a learning curve when you begin using a real-time operating system (RTOS) in your development. Timing, scheduling et cetera will affect your code in ways that are not directly visible in the source code.

Computer scientist Edsger Dijkstra once said, “Program testing can be used to show the presence of bugs, but never to show their absence”. No matter how much developers test their software, they just cannot prove that there are no bugs left.
