Time is passing by so fast, and the year end is approache fast! I’m pleased to announce that a new release of the McuOnEclipse components is available in SourceForge:
Percepio Trace V3.1 for FreeRTOS which includes both Segger RTT continuous streaming and snapshot tracing in a single API
Generation of sources and drivers so they can be used without Processor Expert using McuLibConfig, removal of dependency to NXP Kinetis SDK: components use a generic API approach to have them working with other SDKs.
New contributed ExceptionsHandler component
Callback Setter and Getter in USB CDC stack for simpler option handling
GenericTimeDate with flexible RTC support and added Unix Timestamp functions
LongKey events in Key component
FreeRTOS with optimized task selection on Cortex-M4/M7
In “Overview: From Snippets to Code Generation” I discussed several tools used in my development process. On tool which helps me a lot to get things done is Processor Expert. In this post I’ll give an overview about this tool and reasoning for the pros and cons of using it.
There are cases when I need to do a reset of the device by software. For example I have loaded the application image with the bootloader, and then I need to perform a reset of the microcontroller to do a restart. As a human user I can press the reset button on the board. But how to do this from the software and application running on the board, without user manual intervention? Or if I simply want to reset the system for whatever reason?
Performing a Software System Reset with Kinetis Design Studio
I think the biggest frustration point for any new or even seasoned engineer is the debugging phase: my application finally builds fine, but I’m not able to connect and download it to the target board :-(. In my view the debugging part is the most fragile part of the development process. I’m always very relieved if I can connect to a brand new board, because I know if it does not work, then the problem could be a very bad one, costing my several hours or even days to overcome it.
The final FreeRTOS V8.0.0 has been released last week: time to update the Processor Expert component for it, and this time it is really a major release 🙂 : from V7.5.0 to V8.0.0:
FreeRTOS V8.0.0 Processor Expert Component
FreeRTOS V8.0.0 comes with many small changes, especially it now includes many of the extra casts I have contributed to avoid compiler warnings. And additionally it has a brand new feature: Event Groups.
With this I still have several projects not ported to eclipse. So they are still implemented using the ‘classic’ (non-eclipse based) version of CodeWarrior for S12(X). And I’m using FreeRTOS in the eclipse based IDE with Processor Expert for S08, ColdFire and Kinetis, but not yet for the S12(X). What now? Continue reading →
