Definition of RTEMS IoT Projects

Hi I added an Open Project page for Internet of Things support. This is a very broad category of buzzword bingo and covers everything from Bluetooth and 6LoWPAN to messaging protocols. It can be done on boards like the the Pi or BBB or smaller devices. https://devel.rtems.org/wiki/Developer/Proje

Use red-black tree for Watchdog Handler

How does this interact with the pthread affinity and cpuset size? If we end up with a port that can support more than 32, then do we increase the cpuset size or make applications more to variable cpuset's? What's the intended use? On Thu, Mar 3, 2016 at 8:47 AM, Sebastian Huber < sebastian.hu...

You will need to find out how you can run Rock. Ideally, Qemu will work for it, from what I can tell they used the i386-rtems/pc486 BSP. On Thu, Mar 3, 2016 at 8:11 AM, Sambeet Panigrahi wrote: > > -- Forwarded message -- > From: Sambeet Panigrahi > Date: Thu, Mar 3, 2016 at 2:
