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. The training consists in: Understanding the Yocto Project Using it to build a root filesystem and run it on your target Writing and extending recipes Creating layers Integrating your board in a BSP Creating custom images Application development with an Eclipse SDK Three files are released: yocto-slides.pdf – Yocto Project and OpenEmbedded Training presentation slides (245 pages) give an overview of various build systems, before getting more details about the Yocto […]

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 […]

Linaro 14.10 Release with Kernel 3.17 and Android 4.4.4, Debian ARM64 Port Almost Complete

Linaro 14.10 has just been released with Linux kernel 3.17 (baseline), Linux 3.10.54 & 3.14.19 (LSK, same versions as last month), and Android 4.4.2 & 4.4.4. Most of the work is a continuation of previous months working member hardware, and ARM64, but one particularly interesting point is that 90% of Debian packages have been built for ARM64, and the next version of Debian should have an official ARM64 port. Here are the highlights of this release: Linux Linaro 3.17-2014.10 updated linaro-android topic. In particular, CONFIG_IPV6=y is no longer the requirement for linux-linaro tree builds GATOR version 5.19 (same version as in 2014.08 release). gatord is fixed to build for ARMv8. dropped multi_pmu_v2 topic by ARM LT (no longer used) updated topic from Qualcomm LT (include IFC6410 board support) replaced integration-linaro-vexpress topic by integration-linaro-vexpress64. Starting from 2014.10 release, linux-linaro kernel tree will use the mainline support for 32-bit vexpress boards. integration-linaro-vexpress64 […]

Banana Pro Allwinner A20 Development Board Looks Similar to Raspberry Pi Model B+

Banana Pi development board was launched about half year ago with Raspberry Pi model B form factor, but with more powerful Allwinner A20 dual core processor, and extra interfaces such as SATA. A few months later, the Raspberry Pi foundation launched Raspberry Pi Model B+ with pretty much the same specifications, but a different board layout and connector placement, and LeMaker has now designed a new version of the AllWinner A20 development board called “Banana Pro” that’s somewhat similar to R-Pi B+ board layout, with a 40-pin header, and similar connector placement, minus a few differences, such as using two USB ports instead of four, and the addition of a Wi-Fi module. Banana Pro specifications with differences against Banana Pi highlighted in bold: SoC- Allwinner A20 dual core Cortex A7 processor @ 1 GHz with Mali-400MP2 GPU System Memory – 1 GB DDR3 Storage – micro SD card slot, SATA […]

Qualcomm Releases Userspace Adreno 320 GPU Drivers for Ubuntu

Qualcomm Developer Network has just sent the October Newsletter by email, and they had some news specific to Ubuntu / Linux support on IFC6410 development board powered by a Snapdragon 600 processor. Firs they link to a guest blog post on Qualcomm website entitled “Video Conferencing on Linux with the Qualcomm Snapdragon 600 Processor“, where Qualcomm partner eInfochips stated: Qualcomm Technologies, Inc.’s leadership in mobile market with Linux Android support is well established. As the demand for Qualcomm Snapdragon processors, a product of Qualcomm Technologies, Inc., increase in adjacent markets, the need for non-Android Linux support becomes evident. Which is always good to read. The rest of the post blog provides a few more details about their a low-latency (50ms glass-to-glass) video conferencing solution based on OpenEmbedded build with Linaro Linux Kernel, and making use of Qt5, Gstreamer, and Sofia SIP library. Further improvements will be achieved with hardware video […]
