That however depends on a bit of lowelevel code which isnt available in stock kernels, and replicating this for new hardware would be out of my skill range; I therefore would start the search for suitable SoC by filtering which architecture, or board, has a know-to-work Xenomai port. Even if RT_PREEMPT is easier to get running, you might lack the hires timer support. This list of commits between stock 3.2.21 and a working Xenomai kernel gives an idea of the task: https://github.com/roosen/linux/commits/v3.2.21_AM33xx_core-3.2 - the lesser chore is finding a closely matching package stream, or be prepared to build all of the prerequisites yourself. mazeltov, - Michael > > I did start a blog to document my progress here: > http://lcncolinuxino.blogspot.com/ > > I will certainly have many questions (probably better posted to the > developer list) as I get further along, but this seemed to be an appropriate > time mention what I was up to. > > Regards, > Eric > > > > > > ------------------------------------------------------------------------------ > Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, > MVC, Windows 8 Apps, JavaScript and much more.
