Agreed! I haven't replicated your results here so I'm not 100% sure what's happening, but from my experience the FPGA is programmed and running by the time the UIO devices show up. One thing that could be causing problems is if the FPGA is programmed by U-Boot and then reprogrammed by the Linux kernel. If anything was talking to the FPGA fabric (like the HDMI interface or any of the other "extra" logic in the example designs and not just the HM2 logic) that could trigger BadThings up to and including a kernel panic or system halt. It's also possible there's a startup delay in the FPGA reset logic that's causing the problem. The FPGA may be "running", but still being held in an internal reset condition. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
