Announcing Oracle Java ME Embedded 8.1 Developer Preview for Freescale FRDM-K64F

Java ME 8 is purpose-designed to bring Java-powered software intelligence to a wide range of embedded devices – scaling all the way down to resource-constrained micro-controllers. Since the release of Java ME 8 a few months ago we’ve seen tremendous interest in the industry in leveraging Java as the software platform to bring the next generation of functionality and flexibility to embedded systems and the Internet of Things.

Today, we are accelerating the adoption of Java ME 8 with a Developer Preview of Oracle Java ME Embedded 8.1 on ARM Cortex-M4 devices, in collaboration with Freescale and ARM.

What is it?

The Freescale FRDM-K64F is built around the Kinetis K64F with 120 MHz, 256 KB RAM/1 MB Flash, running ARM mbed OS and with an Arduino form-factor and pin-out. A popular prototyping platform for both the mbed and Arduino communities, now joining forces with the Java ecosystem.

The Oracle Java ME Embedded 8.1 Developer Preview on FRDM-K64F offers:

  • A feature-rich and optimized Java ME 8 runtime in 190 KB RAM, enabling highly functional Java Embedded applications on single-chip micro-controller systems
  • Out-of-the-box support for Java 8 language, core APIs, networking, device I/O, storage, and more
  • Simple installation with a complete and ready-to-run binary, just copy it onto the device
  • Rich development and tooling via Java ME SDK 8.1 and NetBeans 8 IDE
  • Complements existing Java ME 8 platforms such as Raspberry Pi, scaling Java ME 8 from large to small
  • Ideal for evaluation and prototyping of small embedded & IoT solutions

What next?

Presentation: For more information and background have a look at the short slide deck “Introduction to Oracle Java ME Embedded 8.1 Developer Preview”.

Download: The Java ME Embedded 8.1 Developer Preview and the corresponding Java ME SDK 8.1 Early Access #3 are available NOW on the Oracle Technology Network (OTN).

Documentation: The release comes with Release Notes and Getting Started Guide for FRDM-K64F. There is also a full set of Java ME 8 documentation.

So grab a FRDM-K64F board from your favorite electronics shop or distributor, download the Developer Preview, and get started! Head over to the Java ME Embedded OTN forum to ask questions.

And finally, if you are watching the JavaOne 2014 Java Technical Keynote keep your eyes peeled for those little FRDM boards running Java ME 8 … 😉

Just back from Brazil and no time to catch my breath … so much happening:

  • JavaOne Latin America was a blast – so much enthusiasm in the developer community! Check out some of the videos and podcasts, including the JavaOne Community Keynote, OTN interviews with a variety of Java luminaries, as well as the Java Spotlight Podcast #60: JavaOne Latin America: Videos and Podcasts
  • Java 7u2 has been released, featuring an updated VM, support for Oracle Solaris 11, support for Firefox 5 and later, and security fixes. Also, JavaFX 2.0.2 is now included with Java SE to make developing and running JavaFX applications even easier: Java SE 7u2 Release Notes, JavaFX 2.0.2 Release Notes
  • Aligning with mainline JDK development, Java SE Embedded 7u2 has been released as well. This release includes new ports to Linux on PPC and performance improvements on ARM systems by 20-40%. Also, Oracle intends to port JavaFX to Linux on ARM in order to support a broad range of platforms from mid-range embedded all the way to desktops: Henrik’s blog on the Java SE Embedded 7u2 release.
  • Lots of activity around JavaFX as well – interest is really taking off. Point in case: A new project, eFX, has been started on aiming to create a generic application framework for JavaFX 2.0 based on the NetBeans platform: Geertjan’s blog on eFX
  • Finally, OTN put together a list of their “Most Popular Tech Articles of 2011”. Java topics, from Java SE 7 and 8 features, Java EE 6, JSF, and JavaFX dominate the list. Have a look: Our Most Popular Tech Articles of 2011
