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. Thanks to David for the tip. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a […]

Linaro 12.12 Release with Linux Kernel 3.7 and Android 4.2.1

Linaro release 12.12 has just been announced, and includes Linux Kernel 3.7 and Android 4.2.1. The tracking version (stable release) uses Kernel 3.4.22. This release upgrades Android to version 4.2.1, Ubuntu images are now based on Ubuntu 12.10 (Quantal Quetzal) and Linaro U-Boot 2012.12 has been released with support for Origen 4 Quad and Arndale boards. Further improvements have been done for OpenEmbedded ARMv8, where they replaced the php Apache module by php-fpm among other things. On the kernel side, USB drivers have been refactored, and a kernel size analysis have been performed on several platforms. The power management team has mainly worked on big.LITTLE IKS and MP implementations, and it’s the first time LEG (Linaro Enterprise Group) is included in the release, and they worked on UEFI for ARM, GRUB for U-Boot, and provided a Ubuntu server image for Arndale board which can boot via UEFI or UBoot.
