FreeRTOS trace HW/SW with nw.js application

While working on CleanFlight Linux with a I/O micro-controller for extra peripherals, there is no straight forward way to get performance, trace, and general information about the state of the firmware on the micro-controller.


Goal:

• Provide an open source solution to get metrics on the firmware using traceSWO port.

Implementation:

• Use FreeRTOS trace messages and send them out one of the channels of SWO port
• Also allow setting ETM tracing
• Create a GUI (nw.js) and command line tools to parse and show trace data from FreeRTOS
• GUI will show live line/bar charts of Task performance and I/O
• python tools to parse/mine data allows custom reports.

I have several GD32F103C8 red boards, use these to decode the SWO and send trace information to nw.js application.

Thoughts? suggestions?
