NetBSD 7.0 To Support Multi-Core ARM Processors from Allwinner and Freescale

NetBSD is an open source Unix-like Open Source operating system running on a wide range of platforms, from servers and desktop systems to embedded devices. The operating system has supported ARM since 1996, with more recent ports for ARM Cortex A8 and Raspberry Pi, but until recently it did not support SMP (Symmetric multiprocessing) to support more than one core. But NetBSD has now fixed this “anomaly” and the following Allwinner A20/A31 and Freescale i.MX6 boards are now supported: Banana Pi (BPI) Cubieboard 2 (CUBIEBOARD) Cubietruck (CUBIETRUCK) Merrii Hummingbird A31 (HUMMINGBIRD_A31) CUBOX-I NITROGEN6X You can give it a try on Allwinner boards by creating an SD card following instructions on NetBSD / Allwinner Wiki. There does not seem to be documentation for the Freescale boards yet. If Allwinner documentation is up-to-date, this is a headless image, as framebuffer, HDMI, etc… are still in to TODO list, but Gigabit Ethernet and SATA are already supported so it could be tried as […]

Freescale i.MX6 Resources: Development Boards, Documentation, Source Code and Tools

Reader “Mark” recently left a comment saying the NDA on Freescale i.MX6 resources was lifted and documentation and source code were now available for the platform. So it’s time for me to look into it, and provide an overview of Freescale i.MX6 features, list available development platforms, and have a closer look at the documentation, source code and tools for the platform. Freescale i.MX6 Processors In 2011, Freescale initially announced 3 processors in the i.MX6 series for consumer, industrial and automotive markets, but added 2 lite SoC in 2012, and there are now 5 members in the family: Freescale i.MX6SoloLite – Single Cortex A9 processor up to 1 GHz with 256KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D graphics accelerator (Vivante GC355 + GC320) Freescale i.MX6Solo – Single Cortex A9 core up to 1 GHz with 512KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D & 3D graphics accelerator (Vivante GC880 + GC320) Freescale i.MX6DualLite – […]
