Hi Hiroshi, Thanks very much for the help. I'm getting farther. It would help to have the right path ;-) Now I"m doing: sudo modprobe bridgedriver base_img=/home/rick/dspbridge_binaries/ddspbase_tiomap3430.dof64P GT_str="**=01234567" But I still get the same results as far as interrupts. Here is the new (very much larger) output: http://www.efn.org/~rick/pub/dsp2.txt What does your ping.out look like? Here's mine, it's awfully small: -rwxr--r-- 1 rick solar 7248 2008-08-21 13:32 ping.out* What does your ping.out output when you run it? Mine is absolutely silent. Thanks again.
