Hi John,
There’s been a lot of changes in Arm over the past six months or so that you may have seen, i.e. Pelion, which the Mbed team were part of, is now a separate company, wholly owned by Softbank. The core of the Mbed team is now part of the open source software team within Arm.
At the same time, Arm has been conducting a strategic overview of our IoT software and begun to make announcements around this, the first of which were made at DevSummit last October. One of the key parts of this is Project Centauri , which is pulling together industry and security standards to provide foundational software for Cortex-M based microcontrollers. We in the Mbed team are, along with other development teams in Arm, working on a longer term roadmap that brings this together with Mbed, CMSIS, TF-M and other technologies to simplify IoT development, which is, we think, one of the core tenets of Mbed.
So in the short term, we’ve slowed down Mbed work to give the team some space to conduct the engineering investigations needed to underpin this roadmap. We plan to share more on this work in the next few months, so I will update you when we have more details that we can share publicly.
