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 […]

$69 – $89 Wandboard Freescale i.MX6 Solo and Dual Development Boards

The Wandboard is a low cost Linux ARM Cortex-A9 ARM board comprised of a CPU module and an interface board. There are actually 2 versions of the board (single and dual core) which are developed by a team of engineers during their spare time: Wandboard Solo – $69 – Freescale i.MX6 Solo + 512 MB RAM Wandboard Dual – $89 – Freescale i.MX6 Dual + 1 GB RAM Both boards come with Audio I/O, Optical S/PDIF, HDMI, a camera interface, 2 micro SD cardslot, a serial port, an expansion header, USB and USB OTG ports, a SATA connector and Gb Ethernet. The dual version also adds Wifi 802.11 b/g/n and Bluetooth support. There are not so many boards with native SATA support, so for those of you who need SATA this could be really be a good option. [Update: Although there’s a SATA connector on the baseboard, this is not […]

15 Linaro OnAir Sessions about Android, Linux, Debugging and Software QA

Linaro has planned 15 virtual conferences between Monday, August 13 and Saturday, August 18, 2012. Those online events will deal with the work done at Linaro, including software optimization, software QA, Android and Linux kernel development, Open Embedded on ARMv8 and more. Those conferences are public and anybody can join. All times indicated below are GMT+07:00 (Bangkok), so you can either mentally convert the time (recommended), or click on the links below to get the date and time in your timezone. 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 […]
