Linaro Android Tutorial with the Pandaboard

Zach Pfeffer, the tech lead of the Linaro Android working group, gave a tutorial about Linaro Android at Linaro Connect Q4.11. During this tutorial, attendees were shown how to download a recent build for the pandaboard, how to make a bootable SD card image using the linaro-android-media-create command and how to boot the board with it. The full setup was composed of a Pandaboard connected to a HDMI monitor with a keyboard and mouse connected to the board as well as serial to USB cable to connect to the development machine. He also used an SD card reader to generate the bootable Android image. The images are available at Android Linaro Build Service. There are quite a few build named after the supported board (e..g panda for pandaboard, snowball for ST Ericsson Snowball etc..) and the kernel version (tracking = latest linaro kernel, staging = stable linaro  kernel). Then an […]

TI Unveils Sitara AM335x ARM Series Cortex-A8 Processors

Texas Instruments has just announced the new Sitara AM335X Processors and the low cost Beaglebone development board. The low cost Cortex-A8 SoCs start at 5 US dollars per piece and are aimed at upgrading ARM9 solutions (software compatible) and adding new features such as 3D interfaces and touch screen, high resolution displays with faster performance. Texas Instruments says you could take those new upgraded products to market within 6 months thanks to their inexpensive development board (Beaglebone) and complete SDK. There are six models in the Sitara AM335X series: AM3552: Cortex A8 up to 720 MHz. AM3554: Cortex A8 up to 720 MHz with 3D Graphics (PowerVR SGX GPU). AM3556: Cortex A8 up to 720 MHz with programmable real-time unit (PRU) @ 200 Mhz. AM3557: Cortex A8 up to 720 MHz with PRU @ 200Mhz and EtherCat. AM3558: Cortex A8 up to 720 MHz with 3D Graphics and PRU @ […]

Run 2 OS Simultaneously on ARM (OMAP4) with Codezero Embedded Hypervisor

B Labs, a company specializing in ARM Virtualization, was at ARM Techcon 2011 showcasing Codezero, their Embedded Hypervisor to run multiple Linux OS such as Android and Chrome OS on ARM processors. The main purpose of running 2 operating systems is to separate home and enterprise operating systems in mobile devices so that enterprise data is safe. Charbax (ARMDevices.net) interviewed Bahadir Baldan, founder of B Labs, and showed a demo running 2 Android instances and another running Android and Linux in pandaboard. The overhead is 10 to 15% according to B Labs, so the performance hit is minimal. They have already managed to run 4 OS on quad core processors with good performance. They are not able to run Windows operating systems (e.g. Windows Mobile 7.5/ Windows 8) yet, because Cortex A9 processors lack virtualization extensions. This will however be feasible with Cortex A15 processors as binary virtualization will be available. […]

The company will also announce other services at CES 2012 such as I’m Market, an app store to download apps for the watch and I’m Music an app to listen music via the watch. Watch the video below to see the Android watch in […]

ARM big.LITTLE Processing Demo

ARM uploaded a big.LITTLE demonstration by Nandan Nayampally, Director, Product Marketing. The demo runs the Android 2.3 (Gingerbread) with graphs showing CPU usage and when Cortex A7 / A15 is running. At the beginning Cortex A7 handles the background tasks, and when they start the Android Browser, Cortex A15 is used instead to render the page and once this is done, the system switches back to Cortex A7. Scrolling the webpage will increase CPU usage, but this will still be handled by Cortex A7. They did not have to do any modifications to Android, but they just added a big.LITTLE aware Power Management Driver which will be open sourced and integrated in future version of the linaro kernel.

Android 4.0 Source Code To Be Released When Galaxy Nexus Ships

Google never opened Android 3.0 (Honeycomb) source code. It was probably because this OS was only meant to be used with tablets and they feared people would try to use it on smartphone. The good news is that Android 4.0 (ICS) source code will be made available once the Galaxy Nexus ships. Although I’m not sure what license will be used with Android 4.0, that follows exactly the GPL license requirements since you don’t need to release the source code if you don’t provide the binaries. See Jean-Baptiste Queru (Android Open Source Project ) announcement at https://plus.google.com/112218872649456413744/posts/HB5qQHeNKBQ. In the meantime, the GPL source files that match the Android 4.0 / r14 SDK have been made available: Kernel: https://dl.google.com/dl/android/gpl/android-gpl-kernel-sdk-4.0.1_r1.tgz Platform: https://dl.google.com/dl/android/gpl/android-gpl-platform-sdk-arm-4.0.1_r1.tgz Dev Tools: https://dl.google.com/dl/android/gpl/android-gpl-tools_r14.tgz Extra: https://dl.google.com/dl/android/gpl/android-extra-4.0.1-r14.tgz Like the Android did for all Honeycomb release, this is NOT the full source tree for Android 4.0 (ICS), these are only the GPL parts […]
