The main feature of Cockpit project is the hardware isolation.

Each OS has its own hardware resources.

One partition is running on Arm Cortex-A53 cluster for Instrument Cluster, and one is running on Arm CortexA72 cluster for In-Vehicle Infotainment, while two others are running RTOS on Arm Cortex-M4s.

Instrument Cluster’s High Level Operating System (HLOS) uses SD card in the CPU board slot as boot media.

In-Vehicle Infotainment’s HLOS uses eMMC as boot media. For this reason, two SD card images must be built:

• One with a standard Linux BSP used for flashing the other image.

• One used at runtime for booting the board. The image contains firmware, HLOS images for Cortex A-53,

Cortex-A72, and optionally Cortex-M4s.

All BSP components are modified to allow running two HLOS and two RTOS in a secure way.
