</span>Thank you for your information. Somehow what you have just is not the direction<br>
of things we do locally at TRIUMF - for ARM processor based machines<br>
we buy kits like RaspberryPi that run straight linux. Then for FPGA based devices,<br>
it is either straight FPGA (no CPU, cannot run MIDAS) or NIOS2 synthetic CPU (usually<br>
not enough on-FPGA and external RAM to run MIDAS, with any OS), or have an FPGA with<br>
built-in ARM CPU (Cyclone 5 SoC, etc), which again run straight linux.<br></blockquote><div><br></div><div>You can run RTEMS on the Raspberry Pi also. My suggestion was just to</div><div>make things easier to debug without spending any money on any hardware.</div><div><br></div><div>RTEMS supports the NIOS2 and ARM Zynq.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
But for general MIDAS use, it is good health to have non-Linux, non-UNIX ports,<br>
keeps the hardware and os abstraction layers honest.<br></blockquote><div><br></div><div>Similarly, RTEMS currently has 15+ processor architectures and ~175 BSPs.</div><div>We have probably removed that many or more over the years.</div><div><br></div><div>--joel</div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
