Getting Started with 64-bit ARM Development: Hello World and Linux on ARMv8 Fast Models

At the end of last year, ARM announced ARMv8, the first ARM 64-bit ARM archtecture, and last week at ARM Techcon 2012, ARM announced the first ARMv8 cores: Cortex A53 and A57. But since there’s no silicon at the moment, what if you wanted to develop code running on ARMv8 before the hardware is available? The answer is: Fast Models, a Virtual Platform (VP) to accelerate software development. This is especially important for ARMv8 since hardware is not expected to be available for another year. In this post, I’ll first show how to run “Hello World!” in ARMv8 fast models, then we’ll run ARM Linux 64-Bit (Aarch64) in the virtual platform. ARMv8 Foundation Model In order allow the developer’s community to program for ARMv8 (Cortex A53/A57 cores), ARM has made ARMv8 Foundation Model, a virtual platform, available free of charge. This v8 Foundation model provides a basic ARMv8 platform environment […]

Linaro 12.08 Release with Kernel 3.6 and Android 4.1.1 Jelly Bean

Linaro release 12.08 includes Linux Kernel 3.6-rc2 and is the very first release with Android Jelly Bean (4.1.1-R4). The Android platform team has managed to port Android Jelly Bean to all their main development platforms: Versatile Express, Versatile Express RTSM, Samsung Origen, TI PandaBoard, ST Ericsson Snowball, as well as Samsung Galaxy Nexus smartphone. They’ve also added TINY_ANDROID, a minimal Android build that can be used for kernel development, toolchain work and other development where users only need a console. It’s possible to get the source code, build it and access the shell within 10 minutes. U-boot-Linaro has been updated and is now based on the latest upstream release v2012.07. Next month, we might be able to see a preliminary port of Android on 64-bit platform (ARMv8). Here are the highlights of the release: Android Automated Methanol (http://gitorious.org/methanol) browser benchmarking in Linaro Android. Automated over 100 Jelly Bean AOSP tests. […]

Exynos 4412 based Origen 4 Quad Development Board Soon Available for $199 USD

As I wrote a list of the Top 10 ARM Linux development boards, I discovered that Origen 4 Quad development board based on Exynos 4412 quad core Cortex A9 processor is currently in development and will replace the Origen board (Samsung Exynos 4212). This board appears to be similar to Hardkernel ODroid-X board, but pricing won’t be as aggressive as it will sell for $199 (vs $129 for the ODroid-X) in the base configuration. Here are the specifications for the base version (ORIGEN 4 Quad Package-C): CPU Board CPU : Samsung Exynos 4 Quad Cortex-A9 core 1.4 GHz DRAM : 1 GB (POP Type) PMIC : S5M8767A Base Board HDMI support Ethernet (10/100 Mbps), SDcard 2x USB 2.0 Host, 1x USB 2.0 Device Serial, JTAG Connector support (Sub Boards) External I/F MIPI CSI/DSI , Parallel, C2C Sub Boards Sound Board: Realtek : ALC-5631Q-A ORIGEN 4 Quad Package-B is based on […]

Exploring The Performance Impact of PGO and LTO on ARM– Mon, August 13, 5:00 PM Abstract: Profile guided and linked time optimisation (PGO and LTO) are two of GCC’s cross program optimisations that should improve both the startup and runtime of typical programs. We know that they basically work on ARM but don’t know the potential speed up or the work involved in proper support. This session will cover […]
