yes you are, I meant to say 'non-x86' and instead of ARM11 I said Raspberry ;) I used the term because it makes the point of the current x86 lock-in, not because I'm so gung-ho about the platform - it seems to have some serious issues with USB and networking, and the board plug placement is a bit on the weird side > many non-x86 hardware platforms exist out there.

I'd say "linux system which can fulfill the package prerequisites" gave a hint but let me strengthen that say "any washer and dryer of arbitrary architecture with a decent package archive" ;) > > And "appalling RT performance" is a relative term. especially for a sprinkler application, yes; now let's do this and take some timings jokes aside : HAL + RTAPI plus some API and Gladevcp demos for applications where latency istn that much of a concern would make a wonderful debian package -m > > Regards, > Kent > > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
