Petr Hosek, a leader at Google responsible for the team's build systems, compilers, and developer tools, unveiled the first device to be equipped with the Fuchsia operating system. The Fuchsia-based firmware will start to be delivered to smart photo frames for the Nest Hub as part of an experimental update for participants in the Google Preview Program. <\/p>\n

If no unforeseen issues arise during the trial implementation, the Fuchsia-based firmware will be applied to the devices of other Nest Hub users, who will not notice any differences, as the interface built on the Flutter framework will remain the same; only the low-level components of the operating system will change. Previously, the devices sold since 2018, which combine the functions of a photo frame, multimedia system, and smart home management interface, used firmware based on the Cast shell and Linux kernel. <\/p>\n

It is worth recalling that since 2016, Google has been developing a universal operating system as part of the Fuchsia project, capable of running on any type of device, from workstations and smartphones to embedded and consumer electronics. The development takes into account the experience gained in creating the Android platform and addresses shortcomings in scalability and security. <\/p>\n

The system is based on the Zircon microkernel, which is derived from the LK project, extended for use across various classes of devices, including smartphones and personal computers. Zircon expands LK with support for processes and shared libraries, user-level operations, an object handling system, and a capability-based security model. Drivers are implemented as user-space dynamic libraries loaded by the devhost process and managed by the device manager (devmg, Device Manager). <\/p>\n
