Add Wi-Fi to Arduino Boards for $3 with ESP8266 Wi-Fi Serial Module

There has been some buzz around ESP8266 Wi-Fi module, mostly because of its low price, and SDK availability, meaning it could become the Wi-Fi equivalent of ENC28J60 Ethernet module, and that for $5 you could potentially add Wi-Fi to your Arduino board for example. Since then, the price has come down even further, and if you are prepared to buy 5 pieces, you can now get the module for less than $3 / piece shipped, alternatively a single module costs $4, and a complete Wi-Fi + Arduino Uno (clone) kit goes for $15. A community has also been built around the chip, and a several project have been made with Arduino boards and ESP8266 module. The best way to find information is to go to ESP8266 community forum, as well as read the Wiki on github. There’s currently a GCC toolchain for Espressif Systems ESP8266, open source tools for working […]

Linaro 14.09 Release with Kernel 3.17 and Android 4.4.4

Linaro 14.09 has just been released with Linux kernel 3.17-rc4 (baseline), Linux 3.10.54 & 3.14.19 (LSK), and Android 4.4.2 & 4.4.4. Linaro has kept working on their member boards such as IFC6410 (Qualcomm), D01 (Huawei/Hisilicon), Ardnale (Samsung), and Juno (ARM). They’ve also announced they’ll change the tools to build GCC by using cbuild2 instead of cbuild1 for next release, and they’ve enabled a build with gcov (for code coverage analysis) which may mean they’ll work on reducing the kernel size by getting rid off unused code. I’ve also noticed the Arndale and Arndale Octa Ubuntu images are now based on Linux LSK with Mali GPU support since last month. Here are the highlights of this release: Linux Linaro 3.17-rc4-2014.09 GATOR version 5.19 updated topic from Qualcomm LT (ifc6410 board support) and HiSilicon LT updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express […]

Linaro 14.08 Release with Kernel 3.16 and Android 4.4.4

I’m a little late for that one, as Linaro 14.08 was released last Thursday. Nevertheless, this release features Linux kernel 3.16 (baseline), Linux 3.10.52 (LSK), and Android 4.4.4. As usual Linaro has worked on member hardware such as Qualcomm based IFC6410 and ARM Juno &Vexpress boards. They’ve also committed changes for LLVM, big Endian, and added a workload generator tool (rt-app) to the Ubuntu and Android image. This tool has been developed and used by the power management working group, presumably to measure and optimize power consumption under various loads. Here are the highlights of this release: Linux Linaro 3.16-2014.08 GATOR version 5.19 (new version) updated topic from Qualcomm LT (ifc6410 board support) updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT (Landing Team) updated Versatile Express patches from ARM LT updated LLVM topic (follows the community llvmlinux-latest branch) Big endian support (the 2014.05 topic […]

Linaro 14.07 Release with Linux Kernel 3.16 and Android 4.4

Linaro 14.07 has just been released with Linux Kernel 3.16-rc6 (baseline), Linux Kernel 3.10.50 (LSK), and Android 4.4.4. This month, Linaro has continued development on Juno 64-bit ARM development board, as well as other member boards from Broadcom (Capri), Qualcomm (IFC6410), Hisilicon D01, Samsung (Arndale / Arndale Octa), etc.. Android have been upgraded to version 4.4.4 with images released for Pandaboard, Arndale, Nexus 10, and Nexus 7, built with Linaro GCC 4.9. Here are the highlights of this release: Linux Linaro 3.16-rc6-2014.07 released GATOR version 5.18 (same version as in 2014.04) updated basic Capri board support from Broadcom LT. Good progress in upstreaming the code: now the topic has 21 patch on top of v3.16-rc4 vs 53 patches on top of v3.15 in 2014.06 cycle removed cortex-strings-arm64 topic as the code is accepted into the mainline new topic from Qualcomm LT to add IFC6410 board support updated Versatile Express ARM64 […]

Linaro 14.06 Release with Linux Kernel 3.15 and Android 4.4.3

Linaro 14.06 has been released last week with Linux Kernel 3.15 (baseline), Linux Kernel 3.10.44 (LSK), and Android has been updated to 4.4.3. One interesting development this month is that Android for ARMv8 (64-bit ARM) is booting on the fast models using ARM Trusted firmware and U-Boot.  SELinux has been enabled in Android. I could not see much new member hardware, except possibly B2120 (HDK) reference board for STMicro STiH407 “Monaco” STB SoC. Here are the highlights of this release: Linux Linaro 3.15-2014.06 GATOR version 5.18 (same version as in 2014.04) updated basic Capri board support from Broadcom LT cortex-strings-arm64 topic (same as in 2014.02) updated Versatile Express ARM64 support (FVP Base and Foundation models, Juno) from ARM LT. updated Versatile Express patches from ARM LT more HiP0x Cortex A15 family updates from HiSilicon LT (hip04_eth, hip04_defconfig) updated LLVM topic Big endian support (same as in 2014.05) ftrace_audit topic from […]

Cavium ThunderX Server SoC Features up to 48 ARM 64-bit Cores

ARM SBSA specification for server supports up to 268,435,456 CPU cores for the second level of standardization on one or a combination of SoCs. We’re not quite up there just yet, but Cavium ThunderX is an ARM server SoC with up to 48 cores on a single chip, which is the highest number of cores I’ve ever heard of in an ARM SoC. The company created their own custom processor cores using an ARMv8 architecture license, designing an SoC complies with ARM’s Server Base System Architecture (SBSA) standard with the following key features: ARM based SoC that scales up from 8 to 48 cores with up to 2.5 GHz core frequency with 78K I-Cache, 32K D-Cache, and 16MB L2 cache. Fully cache coherent across dual sockets using Cavium Coherent Processor Interconnect (CCPI) Integrated I/O capacity with 100s of Gigabits of I/O bandwidth 4x DDR3/4 72-bit memory controllers supporting up to 1TB RAM […]

Linaro 14.05 Released with Linux Kernel 3.15, Android 4.4.2, and Ubuntu Trusty

Linaro 14.05 has been released with Linux Kernel 3.15-rc5 (baseline), Linux Kernel 3.10.40 (LSK), Android 4.4.2, and Ubuntu has been switched from Saucy to Trusty. More work has been done on big.LITTLE processing and ARMv8 support with notably completing bootstrapping with Debian 64-bit. New hardware platform have started to pop-up such as TI J6-Vayu which must be an evaluation board for Texas Instruments Jacinto 6 dual core Cortex A15 SoC for automotive application, as well as IFC6410, a Snapdragon 600 development board which got a Ubuntu LEB image. This month also marks the first release of Linaro GCC 4.9 toolchain. Here are the highlights of this release: Linux Linaro 3.15-rc5-2014.05 new Android topic (linaro-android-3.15-experimental) uses the resent AOSP code base GATOR version 5.18 (same version as in 2014.04) uprobes topic removed as all patches have been accepted into mainline updated big-LITTLE-pmu topic from ARM LT updated basic Capri board support […]

Linaro 14.04 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.04 has been released with Linux Kernel 3.14 (baseline), Linux Kernel 3.10.37 (LSK), and Android 4.4.2. More work has been done on ARMv8 support, and big.LITTLE for both the Linux kernel and Android, as well as work on member hardware platforms such as Origen, Arndale, Arndale Octa, Broadcom Capri, and Hisilicon D01 boards. GCC 4.8-2014.04 Linaro is said to include performance improvements. Linaro Android engineering builds for Nexus 7 and Nexus 10 have been setup, but I can’t quite find the images. They’ve also added the BeagleBone Black to member builds. Here are the highlights of this release: Linaro Stable Kernel (LSK) 3.10.37-2014.04 Updates to Android support (from Google and Linaro) Added Big endian for ARMv7 and ARMv8 Thermal framework DT support Huge pages and transparent huge pages for ARMv8 Tagged pointers for ARMv8 Non-coherent DMA for ARMv8 Other Features big.LITTLE support – ARM MP patch set, IKS (ARMv7 […]
