Linux BSP and Distribution

The NAVQ+ software platform is comprised of the U-Boot firmware, Yocto Linux and FreeRTOS.

U-Boot

• Runs on the Cortex-A53 cores.
• Performs target initialization from power-on / reset.
• Loads from eMMC (or other supported bootable device) and runs from DDR.
• Provides:
  • Serial console;
  • Ethernet driver for loading images to the target from network;
  • Device driver for eMMC / SD Card, including support for U-Boot self-upgrade capability
  • Sophisticated command interface for maintenance and development.
• Supports:
  • Storing U-Boot environment and Linux images on eMMC / SD Card;
  • Auto-boot feature, allowing boot of OS images from eMMC or other storage with no operator intervention;
  • Persistent environment on eMMC or SD Card for customization of target operation;
  • Load of firmware images to the Cortex-M7 core.

Linux

• Runs on the Cortex-A53 cores.
• Provides device drivers for key I/O interfaces of the i.MX 8M, including
  • Wi-Fi and Bluetooth connectivity.
• Includes Qt / QML framework.

FreeRTOS

• Runs on the Cortex-M7 core.
• Provides device drivers for select I/O interfaces of the i.MX 8M.

Development Environment

• Is based on Yocto v4.0 (Kirkstone) distribution.
• Works on a Ubuntu Linux host system.
