JelinaOSIndustrial edge operating system
Field devices need to run for years, and their systems must continue to evolve. Built on industrial Linux, JelinaOS runs native and containerized applications and incorporates updates, boot verification and recovery paths into the device lifecycle.

Manage operating data separately from the system
Retain a recovery path if an update fails
01 / What changes
Updates may affect site operations, system files and data are mixed together, and recovery after a failure depends on an engineer visiting the site. Over time, known issues remain in older versions, making it increasingly difficult to evolve the device.
Native programs and container workloads can run on the same industrial Linux foundation. Teams choose a deployment method that fits each application and bring their existing software expertise to field devices.
Runtime writes go to an independent data partition, keeping the system and data separate. During routine maintenance, engineers can distinguish the system version more clearly from content generated on site.
The new version is first written to the standby system, then activated and verified after a reboot. If boot or verification fails, the recovery mechanism rolls the system back. Designing the recovery path before the update reduces the manual work needed after a failure.
02 / A better way to work
The active system runs applications while the standby system receives the new version. A reboot switches to the new system for verification, while operating data remains in an independent partition.
Switching systems requires a reboot. The verification result determines whether to continue using the new system or enter the recovery process.
03 / Explore the implementation
The A/B system documentation explains writing to the standby partition, switching on reboot, boot verification and when rollback takes effect, helping teams plan updates around the site’s maintenance windows.
