Android 5.0 Lollipop Source Code Pushed to AOSP

As Nexus 6 smartphone, Nexus 6 tablet, and Nexus Player have now started to ship, Google has pushed Android Lollipop to AOSP (Android Open Source Project), as well as images for Nexus 4, Nexus 5, Nexus 7 (2012 and 2013), and Nexus 10. You’ll soon be able to retrieve the source code with the following command lines [Update: I still can’t use the lollipop-release branch to retrieve the code, so instead you can use android-5.0.0_r1 tag for Nexus 9, or android-5.0.0_r2 tag for Nexus Player / Android TV]: repo init -u https://android.googlesource.com/platform/manifest -b android-5.0.0_r1 repo sync Currently repo init fails with: error: in init -u https://android.googlesource.com/platform/manifest -b lollipop-release –repo-url=https://gerrit.googlesource.com/git-repo –repo-branch=stable: revision lollipop-release in manifests not found But everything should come online soon. In the meantime, you could still browse the code. Anyway that means Android 5.0 images for mini PCs, TV boxes and other devices will hopefully be available in […]

$99 ODROID-XU3 Lite Development Board Powered by Exynos 5422 Octa Core Processor

Hardkernel is known for their low cost Exynos based ODROID boards such as the $59 ODROID U3 board based on Exynos 4412 quad core SoC, and with ODROID-XU3, they also have a more powerful Octa-core Exynos 5422 board which sells for a premium price of $179. The company has now decided to offer a cheaper version of the board, which they call “ODROID-XU3 Lite” and lacks DisplayPort, the current and voltage sensors, and uses an Exynos 5422 processor clocked at 1.8/1.3 GHz instead of 2.0+/1.4 GHz for the original board. Price? A cool $99. ODROID-XU3 Lite specifications: SoC – Samsung Exynos 5422 quad core ARM Cortex-A15 @ 1.8GHz quad core ARM Cortex-A7 @ 1.3GHz in big.LITTLE configuration with Mali-T628 MP6 GPU supporting OpenGL ES 3.0 / 2.0 / 1.1 and OpenCL 1.1 Full profile System Memory – 2GB LPDDR3 RAM PoP (933Mhz, 14.9GB/s memory bandwidth, 2x32bit bus) Storage – Micro […]

How to Flash Firmware to Realtek RTD1195 Media Players

Android TV boxes based on Realtek RTD1195 SoC are cheap (about $60), with a relatively slow dual core Cortex A7 processor, but include fast interfaces such as USB 3.0, Gigabit Ethernet, and sometimes SATA, and are said to be very good at playing videos. After several months of development since they’ve first been spotted, RTD1195 media player are finally shipping. One of the models is M-195, which had its firmware recently released, and can be downloaded from copy.com, filefactory, mediafire, or solidfiles servers. This firmware is based on Android KitKat 4.4.2, with build number rtk-phonenix-eng 4.4 krt160 eng.ton.20141024.094201. Firmware update is pretty easy, and is operating system agnostic, since all you need to do is to basically copy the firmware file to a USB flash drive. A PC is not even necessary, as you can download the file and extract it directly from the mini PC itself. The same procedure […]

Beyond Debug Key Enables JTAG & UART Debugging, Supports OpenOCD

Beyond Semiconductor, a fabless semiconductor company based in Slovenia which develops their own 32-bit BA2x IP cores, has sent me one of their development tool, namely Beyond Debug Key supporting JTAG and UART interfaces either with BeyondStudio for the company’s BA2x processor, or the open source suite OpenOCD for other processors. Since I don’t have any Beyond Semi boards, I instead configured it, and quickly tried it with Atmel SAMA5D3 Xplained ARM Cortex A5 development board, and OpenOCD (Open On-Chip Debugger). The debug tool comes in the package above describing the key features of the kit: Performance Transfer rate in excess of 600 kB/s 30 MHz maximum JTAG clock Less than 20 μW power draw from target board Compatibility Fully compatible with Beyond BA2x processor family Access any 8-bit, 16-bit, 32-bit or 64-bit processors via JTAG Works with all JTAG compliant devices Software Support OpenOCD for access to a range […]

Free Electrons Publishes Yocto & OpenEmbedded Training Materials

Free Electrons is a small (9 people) engineering company focusing on embedded Linux / Android, and open source software, which also happens to have ported several ARM SoC to the mainline kernel. From time to time, they also offer training sessions, and release course materials publicly. Their latest training is a 3-day course dealing with the Yocto Project and OpenEmbedded, using BeagbleBone Black development board for lab sessions, and all materials have been released under a Creative Commons license.

Unboxing of Rippl-TV XBMC Android Media Player

Half year ago, I reviewed Shenzhen Tomato M8 / TM8 Android TV Box. It was the first hardware I received based on Amlogic S802, and although I found overall performance and video playback in XBMC was very good, the firmware was not always stable, and Wi-Fi performance was poor. Shenzhen Tomato has now sent me another model based on Amlogic S802 called Rippl-TV (click for full specs), with an hardware very similar to M8 as we’ll see below, but a completely different firmware that relies on XBMC as the Android launcher. Rippl-TV Unboxing I received the TV Box by Fedex in the following package that reads “Rippl-TV a drop of perfection brings out the best in media…” The package lists the key features of the TV with 4K UHD video playback, XBMC Rippl-TV Edition, Android 4.4 OS (called UtilOS), dual band Wi-Fi, a quad core Cortex A9 CPU coupled with […]

SPMC 13.3.3 Release Adds H.265 Video Playback and Android TV Support

SPMC (Semper Media Center) is a fork of XBMC for Android with some modifications, that you can easily install from Google Play or Amazon AppStore. The latest version is particularly interested as it adds H.265/HEVC codec support for platforms such as Rockchip RK3288, and Amlogic S805/S812, and other SoCs making use of MediaCodec API and libstagefright should also work, including Realtek RTD1195 and Hisilicon K3V2. This version is also the first to support Android TV based on Android 5.0 Lollipop. SMPC 13.3.3 Changelog: Preliminary support for h265 (including RK3288) Preliminary support for Android TV Allow sleep and Daydream to kick in (e.g. on Amazon Fire TV) Add setting to scrape all videos, even if they failed Add “sd” & “hd” to the advanced settings of libstagefright (and mediacodec) for fine tuning Allow fullscreen on Jelly Bean Hide irrelevant video & audio settings Another possible fix for start crash Make the […]
