Memfault vs. Percepio Tracealyzer

If you're running a fleet of embedded devices that has a tight RAM, CPU, & power footprint, Memfault is a must-have. From managing firmware deployments to monitoring every facet of the device lifecycle and performance, this is a solution that is built with a founding team that are the absolute best in the industry. They know your chipset and OS extraordinarily well and in some cases have been able to work directly with the chip vendors to provide support for their SDKs. With Memfault's help, our chip vendor diagnosed an issue in their BLE SDK and dramatically decreased the number of crash events on our devices.

This is a perfect tool to debug complex bugs in your system, especially in regards to inter-task communication. It is also a great tool for beginners, as the documentation is accessible and the support given by the company is excellent

• Great visualization
• Sometimes awkward views (vertical vs horizontal)

• It's not always easy to include/integrate Tracealyzer in the OS build. It would be nice to have a simple install/plug n play method for our target.
• Sometimes, the .bin files from Tracealyzer don't always work and we don't know why

While we started using uCOSIII for our simpler microcontroller products, we also use QNX on more complex targets (full microprocessors) and it is a much more complex platform offering event tracing, memory tracing, and performance measures that are extremely good and integrated. More importantly these tools are fully integrated without any code changes. Tracealyzer is not integrated as much into uCOSIII like QNX's tools, debugger, etc. But, going thru the manual work of adding Tracealyzer to the build, it did help us get to a shippable product.

• Positive: We were able to find some thread priority issues with Tracealyzer.
• Positive: we were able to see timing of events in the sw/hw that we couldn't otherwise see.
