Paul Eremenko, Head of Project Ara, has announced a lot of technical news from Lcu 2014 (Linaro Connect Usa).
The Spiral 2 (Project Ara prototype that use custom chip for modules data exchange) will be ready in October/November. We expect to see it at the next Ara Dev conference to be held in December. Between November and the early months of 2015 is planned the end of development of Spiral 3, the almost final version of Project Ara. Paul Eremenko also announced that Rockchip is working on a quadcore SOC Arm A7 with integrated Unipro technology. Collaboration with Linaro continues: to support modular architecture, Android will be modified in the framework and in the kernel.
The team is working on a preliminary version of Android L that will be published between Q1 and Q2 of 2015. Paul Eremenko also revealed that Google is collaborating with Foxconn for large-scale production of EPM.
At the end of the conference, the Head of Project Ara revealed other news. The modules can not have directly access to the Ram, mainly due to the speed of Unipro (around 2 ms), so the modules will have their own memory. Eremenko has confirmed the certification process for the new modules (to verify their correct operation) before being sold on the Ara online store (however producers will be able to sell directly).
Finally, it will be possible to hotswap the modules except the CPU and the display module.
