I have the memec board, but I don't have time to play on that one. I got to debug the HW one week after I was hired. As far as I can tell, our linux for memec board doesn't load the sysace driver. > > Once I start one write command, the ISR keep coming in. > > Ouch. Tell me about it.

I tried to synthesize chipscope into into our VP20. But don't have much time for it now. It is less of a priority since the sysace is working now for 1.5 months (without ISR). Also, we use linux as Xilinux dev environment but the chipscope only work in Windows platform. Our HW folks don't have time to touch Windows side of Xilinx tools. It make it more difficult to debug SW/HW integration issue. > > > I try turn off the ISR on write with SYSACE register and > > the ppc interrupt control register.
