How to Program STMicro STM8S $1 Board in Linux

In January, I discovered there was such thing as a one dollar development board based on STMicro STM8S103F3P6 8-bit MCU with 1KB SRAM, 8KB flash, and 640 bytes EEPROM, some GPIOs as well as I2C, UART, SPI, ADC, and PWM signals. Links to documentation and source code were provided, but development tools were only Windows based. However, one of my reader informed me SDCC (Small Devices C Compiler) supported STM8, and development in Linux should be feasible. So I decided to buy the board on eBay for $1.62, as well as an ST_link V2 programmer for STM8 / STM32 for $4.52 in order to flash the firmware. The board came pretty quickly, i.e. within 2 to 3 weeks. But due to a lost package, the programmer took nearly 3 months to reach me, as the seller had to re-send after I failed to receive it within 2 months. It comes with 4 wires that need to be connected to RST/NRST, …

Android 4.0 Hardware Graphics Acceleration Coming to More Platforms

The Linaro Android Platform Team has just posted a weekly update to their progress. They are going to release 11.12 very soon with hardware graphics acceleration to 2 of their members development boards: ST Ericsson Nova A9500 Snowball and Samsung Exynos 4212 Origen boards. So if you have any boards or products based on those processors you should be able to get an hardware optimized version very soon. Hardware acceleration is already available on all OMAP4 platform such as Pandaboard, since this was the default Android ICS target. They also introduced support for the ARM DS-5 debugger, an Eclipse plug-in to help developer create high performance performance  and low power native software by integrating a graphical debugger for code generated for the Android Native Development Kit (NDK) and a basic version of the ARM Streamline performance analysis tool. Here’s a list of this week achievements: Key Points for wider discussion Hardware accelerated graphics for Linaro Android Snowball ICS is running. …

LinuxCon 2011 Presentation: Embedded Systems

The fourth presentation entitled  “Embedded Systems” was presented by Tim Harder, developer at OSUOSL (Oregon State University Open Source Lab) on the 16th of August 2011 at LinuxCon 2011. Abstract: This presentation deals with software development for Embedded Systems especially focusing on Linux and open source.  It describes current software development challenges such as fast software life cycle and memory footprint issues, lists several open hardware projects (Beagleboard, Pandaboard, Bug Labs, Gumstix),  microcontrollers (Arduino and TI MSP430), different operating systems (Android, Meego) and toolchain build tools (Buildroot, Yocto) for embedded systems. It also explains specific challenges to embedded software development such a the numerous number of hardware platforms and software & hardware  tools. Finally, it deals with the cross-compilers, emulators (e.g. qemu) and debugging tools (gdb, jtag, serial console, etc…).
