Whether we need them or not, we don’t usually shy away from a development board. [Keith] sent us a tip on the DragonBoard 410c after reading our recent coverage of the latest Beagleboard release. Arrow Electronics is manufacturing (and distributing, not surprisingly) the first Qualcomm Snapdragon 400 series based development board. At the time of writing there are two boot images on the 96boards.org site available for download Android 5.1 and an Ubuntu based version of Linux.
The DragonBoard 410c is stuffed with an Arm Cortex-A53 (Arm block diagram after the break) with max speed of 1.2GHz and support for 32bit and 64bit code. It also has on-board GPS, 2.4GHz WiFi, Bluetooth 4.1, full size HDMI connector, a micro USB port that operates in only device mode, two full size USB 2.0 ports for host mode, a micro SD card slot. In the way of GPIO it has a 40 pin low speed connector and a 60 pin high speed connector, there is also an additional 16 pin breakout for analog audio, and the list goes on (follow links above for more info).
For those of you playing buzzword drinking games not to worry, the board can be made Arduino compatible by using the mezzanine connector and there is a plan for the board to be Windows 10 compatible. Better make that a double!

The folks at Return Infinity just released a new version of their BareMetal OS, a 64-bit operating system written entirely in assembly.
The goal of the BareMetal project, which includes a stripped-down bootloader and a cluster computing platform is to get away from the inefficient obfuscated machine code generated by higher level languages like C/C++ and Java. By writing the OS in assembly, runtime speeds are increased, and there’s very little overhead for when every clock cycle counts.
Return Infinity says the ideal application is for high performance and embedded computing. We can see why this would be great for really fast embedded computing – there are system calls for networking, sound, disk access, and everything else a project might need. There’s also ridiculously small system requirements – the entire OS is only 16384 bytes – lend itself to very small, very powerful computers.
With projects that are computationally intensive, we think this could be a great bridge between an insufficient AVR, PIC or Propeller and a full-blown linux distro. There’s just some questions about the implementation – we feel like we’ve just been given a tool we don’t even know when to use. Any hackaday readers have an idea on how to use an OS stripped down to the ‘bare metal?’ What, exactly, would need 64 bits, and what hardware would it run on?
Check out the Return Infinity team calculating prime numbers on their BareMetal Node OS after the jump.
