Embedded Base Boot Requirements (EBBR) Project Aims to Standardize Booting on Embedded Systems

EBBR UEFI

Desktop and server systems relies on standardized interfaces between the bootloader and the OS like UEFI and ACPI, but for embedded systems the way the bootloader, often U-boot, handles the boot flow may vary greatly between targets. Arm and its partners already worked on this in the server space with the Server Base Architecture Specification (SBSA) , and more specifically the Server Base Boot Requirements (SBBR) within the specification that requires the use of both UEFI and ACPI on servers.  Arm has now done something similar with the Embedded Base Boot Requirements (EBBR) project that targets specifically embedded systems, is based on a subset of UEFI, and works with either ACPI or device tree. EBBR specification once implemented in bootloaders like  U-boot or Tianocore/EDK2 should allow a single version of an OS image to boot on multiple platforms without the per-platform customization required today.. In practical terms it means the U-Boot would have a standardize interface with the OS based …

Compulab CL-SOM-iMX8 SoM Features NXP i.MX 8M Processor for $68 and Up

I just covered one of the i.MX 8M systems-on-module last Friday with Variscite DART-MX8M SoM, but Variscite is not the only company about to launch such modules, and today I’ll have a look at Compulab CL-SOM-iMX8 system-on-module based on the same NXP i.MX 8M dual or quad core Cortex A53 processor. Compulab’s SoM comes with up to 4GB RAM, 64GB eMMC flash, an optional WiFi & Bluetooth module, as well as optional support for Ethernet, LVDS, analog audio, and more. Contrary to most competitors, the company has also made an habit of releasing detailed pricing the basic configuration and per option. But first, let’s go through the specifications: SoC (one of the other) NXP i.MX8M Quad quad core Arm Cortex-A53 processor @ 1.5GHz with Arm Corex-M4 real-time core, Vivante GC7000Lite GPU supporting OpenGL ES 3.1, Open CL 1.2 and Vulkan NXP i.MX8M Dual dual core Arm Cortex-A53 processor @ 1.5GHz with Arm Corex-M4 real-time core, Vivante GC7000Lite GPU supporting OpenGL …

U-Boot Now Supports UEFI on 32-bit and 64-bit ARM Platforms

Intel/AMD x86 based computers now boot via a standard UEFI binary, which can load grub2, allows you to update the command line as needed, or select different version of the Linux kernel. On ARM everything is a little more complicated and messy, as bootloaders such as U-boot need to support different configurations formats. Alexander Graf has been working on implementing UEFI support in U-boot, and it’s now supported by U-boot mainline and enabled by default for 32-bit and 64-bit ARM platforms, but not x86-64 (yet). That means you should now be able to boot any ARM boards supported by mainline U-boot through UEFI. Alexander gave a presentation about his work at an openSUSE event in June, and demonstrated u-boot with UEFI, and GRUB2 support with an openSUSE image running on a Raspberry Pi board.

Atmel SAMA5D3 Xplained Board Unboxing and Quick Start Guide

Atmel SAMA5D3 Xplained is an evaluation board running Linux powered by SAMA5D36 ARM Cortex A5 micro-processor with 256 MB DDR2, 256 MB flash, two Ethernet ports, 3 USB connectors, and more. This embedded board targets industrial automation, networks, robotics, control panels and wearable applications. The only video output is an LCD connector so it is reserved for headless or flat panel based applications. You can check full specs on my Atmel SAMA5D3 Xplained announcement post. The company kindly sent me a sample, so that I can share my experience with the board. I’ll first post some unboxing pictures, show how to get started with the pre-installed image, and build my own Linux image. The board can be purchased for $79 from Atmel e-Store, as well as several distributors (P/N: ATSAMA5D3-XPLD).

U-Boot & Linux BSP for STMicro STM32 Discovery Board

If you want to run Linux on STM32 Discovery board, more exactly STM32F429 Discovery board, it’s now possible thanks to Emcraft Systems’ BSP for STM32F429 Discovery Board. It will only work on that particular version of the discovery board as it features 64Mbit external SDRAM, which is required for uClinux, and missing on other STM32 Discovery boards. You can either get u-boot and (uC)Linux from the company’s github account which contains the required patches, but lacks complete documentation, and a default config file for the kernel for example, or purchase a BSP ($33) with 3-month support, and pre-built u-boot and Linux binaries. There’s also publicly available documentation explaining how to flash the bootloader and the kernel among other things, and links to relevant external resources, without the need to spend any money.
