On printf debugging
Printf calls are SLOW. Writing 25 bytes over a 115200 baud serial line takes a whopping 2 milliseconds, not counting any string formatting. This may change the system behavior and hide the problem you are chasing. This also means that printf calls can't be used in any time critical code, such as interrupt handlers. Additional [...]

Troubleshooting J-Link RTT streaming
The easiest way to stream Tracealyzer traces from an RTOS is often via a SEGGER J-Link debug probe, using the RTT feature. This relies on a RAM buffer that is read by the J-Link probe while the target system is executing. This is usually fast and reliable, but in case you encounter issues, please check [...]

RTOS Debugging: Everybody wants the fork
A clear indication that you may have a deadlock problem is when multiple tasks suddenly stop executing, although no higher priority tasks are running.
RTOS Debugging: When the important stuff has to wait
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.
RTOS debugging: Chasing the jitter bug
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.
RTOS debugging: When the CPU has too much on its hands
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 at Embedded Vision Summit – the Video
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 [...]
