• Linux on ARMHardware and software development is going full-steam ahead for ARM servers.  After Calxeda and AppliedMicro server SoCs – based respectively on Cortex A9 and ARMv8 architecture – have been announced and Ubuntu focusing further ARM development on Servers (Calxeda, Marvell and ARMv8), Oracle has released the Java SE server compiler – a throughput optimizing JIT compiler -  for ARMv7. The ARMv7 server compiler is part of Java SE for Embedded 7 Update 2.

  • Linux on ARMThere's still one week until the work will be officially announced, but the open-source "Lima" open-source graphics driver project has surfaced. The Lima driver? This is going to be the open-source driver built for ARM's Mali graphics processors. Lima is what the project's being called for the story Phoronix exclusively broke last week, An Open-Source, Reverse-Engineered Mali GPU Driver.

  • Linux on ARMPHYTEC’s production-ready phyCORE-OMAP4430 and Linux BSP provide a core foundation so that developers do not have to design an OMAP4 based embedded application from the ground up.

  • Linux on ARMLinux 3.3 can change the size of ext4 filesystems faster and supports ACPI 5.0, LPAE for ARM processors, Ethernet teaming and hot replace for software RAID. Meanwhile, Linux 3.1 has reached the end of the line, and the Linux Ate My RAM web site explains why Linux often appears to use all of the RAM.

  • Linux on ARMThere is some exciting news to break today on Phoronix... Coming up at FOSDEM (the Free Open-Source Developers' European Meeting in Brussels) will be the formal announcement of an open-source, reverse-engineered graphics driver for the ARM Mali graphics processor. OpenGL ES triangles are in action on open-source code. Will this be the start of fully open-source ARM graphics drivers for Android and Linux?

  • Linux on ARMLinaro is excited to announce that we will once again be having our Demo Friday at Linaro Connect Q1.12 to show the latest Linux developments on ARM.Linaro members, partners and community offer interactive demonstrations showcasing ARM-processor-based boards and Linaro builds of Android and Ubuntu.

  • Linux on ARMlibavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++ and I've already written a post to cross-compile libavg 1.6 in Ubuntu (with linaro cross toolchain) and using Beagleboard qemu image.

  • Linux on ARMI had previously installed Sourcery G++ ARM Linux toolchain in Ubuntu to build some software running in Debian, but I encountered some issues with some libraries (libavg) that use gethostbyname in static libraries without any easy way to make it dynamic.

  • Linux on ARMOpenFIMG, the open-source graphics driver project that began as the GLES6410 driver for providing a full open-source 3D stack for some Samsung ARM SoCs, continues to be developed and is moving on with its OpenGL ES accelerated support.

  • Linux on ARMFXI's Cotton Candy at CES is proof of how Linaro can help a system vendor rapidly develop a product that is running the latest Android ICS and Ubuntu. FXI said in it's announcement it leveraged the Linaro for ARM open software and tools and leveraged its access to the ARM Mali Graphics software development ecosystem.

  • Linux on ARMRed/System, the new programming language that is used in the Syllable project, has reached its next milestone: an ARM code generator backend for its compiler. It supports Android (screenshot) and generic ARM Linux (screenshot on Debian). Earlier, the backend for generating Mac OS X executableswas already completed (for x86 CPUs so far).

  • Linux on ARMLLVM 3.0 was released some time ago and I've thought it'll be good to give it a try on stock Ubuntu 11.10 ARM. That means I've tested LLVM 3.0 with Ubuntu provided GNU C++ 4.6.1 and Clang 2.9. GNU C++ configuration looks:

  • Linux on ARMThere are plenty of low cost Linux development boards based on Cortex A8 or A9 such as the Beaglebone, as well as some devkits based on ARM7 and ARM9 such as SAM9 development kits , but if your application is cost sensitive you can also switch to micro-controllers using Cortex M3 or M4 based development boards such as Emcraft SmartFusion devkits. You can run a functional uCLinux system with 1MB of RAM and 1MB of flash including the TCP/IP stack.

  • Linux on ARMChristian Robottom Reis, Engineering VP at Linaro, announced last week that an Ubuntu 12.04 LTS (Precise Pangolin) ARM port of the OpenJDK 6.0 package for Ubuntu is available for download and testing.

  • Linux on ARMIf you have not noticed yet, then please note that GHC 7.4.1 Release Candidate 1 is out. Please also note that 7.4.1 will be the first public release which will support registerised compilation on ARM/Linux platform. If you are a haskell fan and do have some ARM/Linux platform available, please do not forget to give it a try.

  • Linux on ARMOpen-source software engineering group Linaro has pushed out a build of Android Ice Cream Sandwich for low-cost development boards from Samsung and ST-Ericsson. The build supports hardware acceleration for Systems on a Chip utililzing ARM's Mali-400 graphics processor.

  • Linux on ARMLike most distributions, Fedora uses binary software packages (RPMs in this case) to manage installed software. These packages are built using complex sets of build dependencies (other software packages), some of which are not explicit dependencies but rather implied through their fixed presence in the standard "buildroots" (chroot environments containing a basic set of packages) used in the Fedora build infrastructure.

  • Linux on ARMThe Fedora distribution is often associated with laptops and desktops using x86 processors. These systems are cheap, powerful, and readily available to developers, and so it would naturally follow that they would be well supported. But Fedora has long supported systems based upon architectures other than the venerable x86.

  • Linux on ARMHere at ARM, a colleague recently wanted to port Linux to a prototype of a new high-performance Cortex-A9 based platform. To develop and debug this port, he needed to be able to set breakpoints, view registers, view memory, single-step at source level, and so on, in fact all the normal facilities provided by a debugger, but he wanted to do these both before the MMU is enabled (with a physical memory map), and after the MMU is enabled (with a virtual memory map).
