The ARM will be given priority compared to CF as it has got the peripherals which are really the needs of the present day handheld systems. I am considering the major use of these processor in handheld devices.
Yes, both have evaluation boards and support software: Here is what Freescale says about supporting ARM with "the i.MX28 evaluation kit, multimedia codecs and complete board support packages for Linux and Windows Embedded CE..." More info at:
Regarding Coldfire Freescale says: "Evaluation and demonstration systems for the MCF5441x family are available now..." More info at:
Wow, what a great set of options for designers! Every time I turn around there seems to be another new product line or lower cost increased performance offering being announced. I can't wait to see what these will be used in. Are there evaluation boards available? I can say that much of the effort to migrate to a new platform is mitigated when there are good evaluation boards and software examples.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
