Human machine interfaces (HMIs) and display systems in industrial and building automation, security panels, point of sale (POS) systems, door phones, and IoT edge devices, such as a network gateway or an edge server, require secure and robust over-the-air (OTA) software updates. For these use cases, integrating OTA updates with Renesas RZ/G2L and Yocto 3.1 Dunfell is a common requirement.
This blog guides embedded hardware designers and developers who want to deploy and manage secure OTA software updates to a fleet of embedded devices, leveraging Renesas RZ/G2L and Yocto 3.1 Dunfell integrations.
The Renesas RZ/G2L microprocessor includes a dual-core Cortex-A55 (1.2 GHz) CPU, 16-bit DDR3L / DDR4 interface, 3D graphics engine with Arm Mali-G31, and video codec (H.264). With various interfaces, including camera input, display output, USB 2.0, and gigabit ethernet, the Renesas RZ/G2L microprocessor is ideal for applications such as entry-class industrial human-machine interfaces (HMIs) and embedded devices with video capabilities.
The Renesas RZ/G2L is built on high-performance CPU cores with various accelerators and peripheral functions. The RZ/G2L provides high speed, real-time control; high speed (maximum 600MHz) 32-bit Cortex-R CPU core and large tightly-coupled memory (TCM) realize deterministic real-time response. The RZ/G2L also supports embedded Vision AI for industrial-grade heat and power efficiency, delivering high-speed AI inference at low power consumption. The RZ/G2L also supports an HMI for drawing capabilities, camera input, and audio input for WVGA, WXGA, and 2D graphics are supported based on RZ/A. There are also built-in 3D drawing and full HD video codec functions based on RZ/G.
With Renesas RZ/G2L, engineers can easily implement high-resolution HMI and embedded AI solutions, as well as real-time control and industrial ethernet connectivity.
The Renesas RZ family of 32-bit and 64-bit microprocessors (MPUs) are designed to enable solutions that Renesas believes are required for the smart societies of the future. Through high-performance CPU cores and various accelerators and peripheral functions, embedded engineers and developers can implement high-resolution HMI, embedded vision, embedded AI, real-time control, and industrial ethernet connectivity.
RZ/G2L is a general-purpose MPU for Vision AI, HMI, and IoT Edge applications.
Note: Mender has been verified to work on a Renesas RZ/G2L board, including U-Boot-based boards, for which the Mender integration checklisthas also been verified. The Renesas Verified Linux Package (VLP) works with the whole RZ/G2 and RZ/V2 family of MPUs. This reference integration can also be used to run other MPUs in the family as well.
