I don't think I'll ever understand how these FPGA's work, but I am curious, Pluto uses Altera, the 7i43 uses Xilinx, each with its particular driver, no other driver is loaded, since both seem to have the same problem, is there something in common between the two FPGA systems that might be causing the problem or are we just lucky? Does this problem show up only with EMC2 or RTAI? From a brief search, it seems that FPGA development is not very open-source friendly, that doesn't sound like a good thing. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
