Linux ARM and Texas Instruments

  • Linux on ARMLinux 4.9 added Greybus staging support, improved security thanks to virtually mapped kernel stacks, and memory protection keys, included various file systems improvements, and many more changes.

  • Linux on ARMLinus Torvalds released Linux 4.9 on Sunday - Linux 4.8 brought us an HDMI-CEC framework, a new kernel documentation system is now based on Sphinx, a user-space GPIO subsystem and tools, file systems improvements and more.

  • Linux on ARMThere is support for a number of new ARM platforms with the in-development Linux 4.9 kernel. Perhaps most exciting to end-users with the ARM updates for Linux 4.9 is the mainline Raspberry Pi Zero support as well as supporting the LG Nexus 5 smartphone, among other new hardware support. Here are some of the highlights:

  • Linux on ARMLinux 4.5 added support for GCC’s Undefined Behavior Sanitizer flag (-fsanitize=undefined) which should make the Linux kernel even more secure,an implementation of the next generation media controller, some performance improvements for file systems, etc…

  • Linux on ARMThe development of Pyra open source portable gaming console started in 2014, and after over two years of hard work, the developers are now ready to take pre-order of the Texas Instruments OMAP 5 powered device running Debian Linux.

  • Linux on ARMIf you’ve found yourself needing to quickly demo a system that does not look like a mess of wire to a customer, or your project is requires low production volumes, making the cost of designing your own and mass-producing the hardware prohibitive, Tibbo Project System might be worth looking into. It features an almost bare board powered by Texas Instruments Sitara processor, and a large area for Tibbit blocks to add features as needed, as well as an enclosure.

  • Linux on ARMEurotech’s rugged “ReliaGate 10-11” IoT gateway runs Linux on a TI AM3352, offers numerous options, and is supported with an updated ESF 3.3 framework.

  • Linux on ARMElesar’s “Titanium” is a feature-rich board based on TI’s AM5728 SoC, featuring dual Cortex-A15, dual DSP, and dual Cortex-M4 cores, plus a dual-core GPU.

  • Linux on ARMEmbedian’s “SMARC-T4378” module runs Linux or Android on TI’s Cortex-A9 AM437x SoC, and features up to 1GB RAM, 4GB eMMC, dual GbE, and an optional carrier.

  • Linux on ARMHaoyu Electronics brought us several Allwinner and Rockchip Marsboard in the past few years, and now they’ve released a version based on Texas Instruments AM335x processor, with a form factor and features similar to the Beaglebone Black, but comprised of a baseboard and system-on-module.

  • Linux on ARMWhen I cover system-on-modules (SoM), companies will usually provide some BSP (Board Support Packages) for older kernels, and did not submit their changes to mailine kernel, so I was interested in a news from Emtrion entitled “DIMM-AM335x: Linux mainline support ready“, which actually means they’ve done the work to support a recent Linux kernel (3.14) and provides instructions and code (device tree files), but did not submit patches to the linux-arm-kernel mailing list to get their changes added to kernel.org.

  • Linux on ARMEmbedian launched its first SMARC form-factor computer-on-module, running Linux or Android on a 1GHz TI AM335x SoC, and supported by a SMARC carrier board.

  • Linux on ARMMYIR announced a Linux- and Android-ready COM called the “MYC-AM335X” with six versions of the TI Sitara AM335x SoC, plus a baseboard and touchscreens.

  • Linux on ARMLinux is a free and open-source software (F/OSS) operating system. TI and its partners provide a complete spectrum of Linux software and services (see: Distributions below). TI provides Linux Software Development Kits (SDK) to ensure developers an easy set up and out-of-box development experience.

  • Linux on ARMISEE announced a highly compact single board computer powered by a 2GHz dual-core Cortex-A15 based Texas Instruments OMAP5432 system-on-chip. The IGEPv5 SBC ships with a Yocto-built Linux stack, but also supports Android, and is packed with I/O including five USB ports, mSATA, microSD, HDMI, DisplayPort, audio in/out, gigabit Ethernet, WiFi and Bluetooth wireless, and more.

  • Linux on ARMThe Arduino line of open source electronic prototyping platforms is getting some major upgrades. Earlier today, the first Intel-powered Arduino was announced, and it will be available by the end of November.

  • Linux on ARMTimesys announced embedded Linux support for a pair of computer-on-modules that combine CPU, DSP, and FPGA functions on tiny, SODIMM-style cards. Critical Link’s MityDSP-L138 series COMs are based on a Texas Instruments OMAP-L138 ARM9+DSP system-on-chip processor, along with an optional Xilinx Spartan-6 FPGA.

  • Linux on ARMMost of the ARM cores available today in little single board computers are either A8 or A9 cortex. The ARM A15 CPU cores should be around 40 percent more powerful than an A9 core running at the same clock speed. The A15 CPU can be found in some consumer oriented machines such as the Nexus 10. Most devices with A15 cores are dual core configurations as of mid 2013.

  • Linux on ARMOn May 28, Canonical announced that several vulnerabilities had been found in the Linux kernel packages, affecting the OMAP4 kernel of the Ubuntu 12.04 LTS (Precise Pangolin) operating system.

  • Linux on ARMOn April 8, Canonical announced that several vulnerabilities had been found in the Linux kernel packages, affecting the OMAP4 kernel of the Ubuntu 12.04 LTS (Precise Pangolin) operating system.
