Embedded Linux Quick Start / Tutorial Videos

Free Electrons recorded some videos from the Embedded Linux Conference Europe, in Cambrigde, United Kingdom on October 2010 by Chris Simmonds, the founder of 2net Limited, a UK company providing training, consultancy and custom software for Linux and other embedded platforms. The videos can either be downloaded in webm HD format at http://free-electrons.com/blog/elce-2010-tutorial-videos/ or you can watch them in HD format below. The PDF slides for the three parts and the lab notes are available at http://elinux.org/images/c/cc/Linux-quick-start.tar.gz The first video (53 minutes) deals with the following key points: Genesis of a Linux project The four elements: Tool chain; boot loader; kernel; user space Element 1: Tool chain Element 2: Boot loader The second video (1h19m) focuses on: Third element: Kernel Fourth element: User space The last video (1h07m) is more practical as it shows how to use embedded Linux on an NXP LPC3250 Stick (ARM9): Description of the hardware Installing […]

Rockchip RK2918 based Set-Top Box and Laptop

Rockchip RK2919 is apparently being implemented in many tablets such as Arnova 10, but they are also used in STB / media players and Laptops. Rockchip showcased their set-top box reference design at Hong Kong Electronics Fair 2010. Their board features 100MB Ethernet, one USB host port, one HDMI video output and one SD Card connector. The BOM cost is around 50 USD. The reference designs runs Android 2.3 (gingerbread). They also exhibited a laptop based on RK2918 supposedly manufactured by one of their customers running Android 2.3. There are no details specs nor price information available yet. But with an ARM Cortex A8 running at 1.2Ghz it should offer decent performance compared to existing ARM based laptops although I’d rather have Ubuntu preloaded (now optimized by Linaro) than Android on this kind of device. Here’s a video by Charbax (armdevices.net) of this laptop.

Boot Linux in 300 milliseconds

MakeLinux.com managed to boot Linux from the bootloader to console within 300ms using a customized (and minimal) version of Linux running on Beagleboard based on TI OMAP 3530 (Cortex A8) as per their Super Fast Boot project. Here’s the analysis of the boot sequence and timings: Logging starts at 70 ms from reset. Boot time from reset is 300 + 70 = 370 ms. Logging starts at 330 ms from power on. Cold boot time is 330 + 300 = 630 ms. Loading of 1.5 MiB Linux image from NAND takes 237 ms with throughput 6 MiB/s. Code execution takes 60 ms or 43M CPU cycles. (For other CPU frequency execution time is different, but the number of processor cycles is the same) The most time-consuming operation is coping firmware from NAND flash. They used a Linux 2.6.32 kernel from DVSDK 3.01, in a minimal configuration (900KB footprint), the boot […]
