Part 1 – Setting up the GCC ARM Toolchain | Hertaville. This is the first part of a three part tutorial on setting up a free and fully functional GCC + Eclipse + OpenOCD (ST-LINK V/2) GDBServer environments for use with the STM32F0Discovery board. Links to the second and third parts of this tutorial are provided below: In this blog entry I will provide instructions on how to install an arm-toolchain on a Windows 7 machine and how to use it to compile a simple blinking LED project on the STM32F0Discoveryboard from the command line. There are a variety of arm-toolchains out there.
These include arm DevKit pro, Yagarto, Mentor Graphics CodeSourcery Lite, and the gcc-arm toolchain. Of these toolchains, the two most popular ones are the codesourcery Lite (owned by mentor Graphics) and the gcc-arm toolchain. Traditionally I would use the Codesourcery Lite toolchain. Other nice to haves are the Procedure: First download and install the gcc-arm toolchain (.exe file) Figure 1. Figure 2 Compiler version information. Hack a Day.

Embedded Systems | Embedded System Design Blog. “Embedded Linux Primer”: A Review « David’s Linux Blog. A review originally published on LinuxQuestions.org: “Embedded Linux Primer” by Christopher Hallinan is an excellent resource for anyone looking to use Linux in an embedded system. It does not cover basics, so is more targeted to experienced Linux or embedded systems developers looking to move to Linux embedded systems.
The book covers a variety of topics including the Linux kernel’s interaction with hardware, system initialization, design considerations when working with an embedded system, and porting Linux. The book provides a detailed description of most of these topics, including many step-by-step directions on reference implementations. The book does not provide command-by-command howtos for many of the steps involved, but the details should be obvious to anyone familiar with basic kernel building and software development. The book also briefly discusses the new hard real-time support for the Linux kernel, including hardware-specific implementation issues.

Biggest problems for embedded systems developers? Why would anyone pay for an RTOS? Barr Code. During the Gulf War, twenty-eight U.S. soldiers were killed and almost one hundred others were wounded when a nearby Patriot missile defense system failed to properly track a Scud missile launched from Iraq. The cause of the failure was later found to be a programming error in the computer embedded in the Patriot’s weapons control system. On February 25, 1991, Iraq successfully launched a Scud missile that hit a U.S. Army barracks near Dhahran, Saudi Arabia. The 28 deaths by that one Scud constituted the single deadliest incident of the war, for American soldiers. Interestingly, the “Dhahran Scud”, which killed more people than all 70 or so of the earlier Scud launches, was apparently the last Scud fired in the Gulf War. Unfortunately, the “Dhahran Scud” succeeded where the other Scuds failed because of a defect in the software embedded in the Patriot missile defense system.

Silverlight Developer » Blog Archive Setting up GCC for the STM32F4 Discovery Board » Silverlight Developer. Setting up GCC for the STM32F4 Discovery Board A few days ago I wrote this post about the STM32 Discovery board and my experiences setting this board up with the IAR Embedded Workbench Kickstarter for ARM. In that post I mentioned that there are some free development tools available for this board, namely the GCC tool chain. I was going to leave these tools until I reached the point where I needed to remove the code size restriction which is in place for the IAR toolset. Well I could not resist investigating this tool chain further. Installing the Software A quick visit to Google lead me to Hussam Al-Hertani’s blog where there are a number of articles which discuss setting up the GCC tool chain for the STM32F0 Discovery board.
These three articles provide a comprehensive overview of the steps you need to follow: Also included on the blog is an overview of the GCC compilation process. Installing the Tools The installation process went reasonably well with only a couple of issues. 11.while (1) Best 'blogs' for embedded systems - 24 march 2009. Another example of blogging in our industry is what you might call shameless, self-promotional corporate blogging in favor of one company and its products. Not that this is bad, but be aware when you read this sort of blog that you are reading the company's 'party line' as it were.
The best - and Mike Hall's is probably the best - are still 'selling you' on using the company's products, but that said, they are doing a good job at it, and the product that they have to sell is a respectable and useful product. Enter Windows CE and Mike Hall. Mike Hall is a product marketing manager at Microsoft, and he maintains a very up-to-date blog on Windows Embedded at . What's great about his blog is is is both very techie about Microsoft's Windows Embedded products, and Mike also highlights interesting announcements for the Windows Community, such as the recent winners of the Spark contest. VDC Market Research On Target: Embedded Systems Blog. When Apple announced the iPhone 5s in September 2013, much of the popular press hailed the device’s inclusion of fingerprint sensing (dubbed Touch ID) as a major breakthrough in mobile security.
The more astute journalists pointed out that Motorola had brought to market fingerprint scanning in the Atrix 4G handset back in February 2011, more than two and a half years earlier. As an owner of the Atrix 4G since its early days, I can provide some insight into the real-world ups and downs of using a fingerprint scanner on a daily basis, although the proliferation of fingerprint devices presents greater security concerns. In terms of usability, the fingerprint method clearly surpasses PIN or password or pattern input as a way to unlock a mobile handset, particularly when it’s a function that gets executed dozens of times a day. It’s one of the reasons that I have hung on to the Atrix 4G as one of my phones for this long.
Motorola Atrix 4G fingerprint sensor. Hack van de dam. Linux 2.6.33 features for embedded systems - Free Electrons blog. Interesting features for embedded Linux system developers Linux 2.6.33 was out on Feb. 24, 2010, and to incite you to try this new kernel in your embedded Linux products, here are features you could be interested in. The first news is the availability of the LZO algorithm for kernel and initramfs compression. Linux 2.6.30 already introduced LZMA and BZIP2 compression options, which could significantly reduce the size of the kernel and initramfs images, but at the cost of much increased decompression time. LZO compression is a nice alternative. Though its compression rate is not as good as that of ZLIB (10 to 15% larger files), decompression time is much faster than with other algorithms. See our benchmarks. This feature was implemented by my colleague Albin Tonnerre. For systems lacking RAM resources, a new useful feature is Compcache, which allows to swap application memory to a compressed cache in RAM.
Unfortunately, each kernel release doesn’t only carry good news. Embedded Systems Blog - Embedded Systems Academy. Although ESAcademy is not an active member of the CiA 443 group, we have several customers and business partners using CiA 443 and came across a potential reliability issue in regards to bit rate changes. It is our understanding that the reliability requirements for CiA 443 sub-sea applications are very high. Bootloaders are written and tested in a way that even power failures at any time or severe communication errors can not break the system. In worst case, an application is not programmed and a device remains in bootloader mode and is simply re-programmed again.
However, allowing the CAN bit rate to change with the currently specified mechanisms bears the risk of one or multiple devices failing. If in a CAN network devices are not configured to use the same bit rate, communication fails at a very low level. How could such a situation occur? The Layer Setting Services (LSS, see CiA 305) allow the setup of a bit rate, if all devices connected to a network support these services. 1.) 2.) Agile methods. I'll be the first to admit that I'm not an eager adopter of Agile Methods, but I believe that there are some good ideas in the agile methods arena (and good ideas elsewhere as well).
Based on some recent experiences I believe that agile can produce good long-lived embedded software ... but that it requires some things that aren't standard agile practices to get there. Some folks use the "agile" banner as an excuse to have an ad hoc process. That's not going to work out so well for most embedded software. So we'll just move past that and assume that we're talking about an agile methods approach that uses a well defined process. (I didn't say "tons of paper" -- I said "well defined. " That definition could be a single process flow chart on a whiteboard, some powerpoint slides, or the name of a book that is being followed.) One of my major concerns with Agile as I have seen it practiced (and described by advocates) is that it is too light in Software Quality Assurance (SQA).
