Portable, battery powered devices are sweeping through society like wild fire.  Mobile computing and sensor devices are springing up everywhere providing engineers with not only a plethora of data but…

ARM architecture is supported by all popular RTOS vendors in embedded. Here is a table showing the RTOS companies, their products, and an indication of which ARM processors they support.

This blog describes how to get Android running on ARM-based SoC boards. We run through the overall procedure and point out potential pitfalls and other things that you may encounter.

Today, using one of the early examples from the CUDA toolkit, I’m going to introduce a neat feature of CUDA 5 and CUDA 5.5 - dynamic parallelism - and how to use Arm DDT to debug it.

Blog orgininally posted on 11 July 2011 on blogs.arm.comHaving chosen the optimal implementation, as described in the previous blog (Elba - How do we know it works?) we now turned our attention to power…

This tutorial explains how to have a LAMP server running Drupal on a PandaBoard. These instructions will apply to any other Cortex-A platform with few or no changes.The growing variety of ARMv7-based inexpensive…

Nowadays web browsers are among the most widely used software tools. You can find them being used everywhere on devices ranging from phones and tablets to personal computers. The heart of all browsers…

ARM® DS-5TM Streamline Performance Analyzer, part of the ARM DS-5 toolchain, is an useful tool for developers doing system level software optimization for ARM Linux and Android platforms. Streamline…

The hwmon is a generic Linux kernel subsystem, providing access to hardware monitoring components like temperature or voltage/current sensors. Traditionally interfaced via external buses like I2C, many…

ARM-based platforms come in a range of processor configurations, and these platforms often have more than one ARM processor.  Traditionally these have been Symmetric Multi Processing (SMP) systems, where…

This blog shows step-by-step how to build the UEFI software and debug it at source level, including all dynamically loaded modules (DLLs), using the ARM Development Studio 5 (DS-5) toolchain.

This blog covers three areas of GCC’s command line options: CPU, floating point and SIMD (Single Instruction, Multiple Data) acceleration.

It all started back in 2008, I'd been looking at what the Software Bill-of-Materials would be for an ARM-based Netbook. I'm a great fan of JEOS (Just-Enough-OS) to support the end users software…

Embedded devices have rapidly evolved in the past decade. Although these devices are capable of running advanced web and desktop applications with sufficient performance, further improving the software…

IntroductionIn the information era with its increased use of mobile devices to communicate and access information, web browsers constitute the central component to navigate through the vast amount of information…

The need for quality professional tools for cross platform development when battling obscure software bugs and performance issues cannot be understated. With the ARM® Development Studio 5 (DS-5™) Community…

DirectFB (Direct Frame Buffer) is a graphics library that is widely used in embedded systems, especially home market. More and more applications or libraries choose DirectFB as backend, such as Cairo,…

Great leaps in human knowledge are linked to advancements in tools. For software engineers the debugger is a cornerstone tool to create reliable products. We engage in a running battle fighting both the…

Here 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…

This blog covers the use of two powerful debugging techniques — stack frames and instruction trace — to debug random or timing-related bugs on ARM processor-based targets.Timing-related and random bugs…

In this blog you will find information about semihosting, an implementation of the C library that uses a JTAG debugger to interface the world. Semihosting is very useful for board bring-up, as it works…
