It occurs to me that perhaps the pulses are real and the underlying problem is that there's a hardware fault causing the decoupling to not work as well as it should. Anything from a broken etch run to a pick-and-place failure causing that particular board to not have all the decoupling it's supposed to could cause this - I'm speculating, of course, but such failures _do_ happen. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML [email protected] / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
