In addition to the reasons you have outlined, they have the same motivations to not tell anyone about it if they did put something like that in. So it very well may be there, but it's useless to us if we can't figure out how to use it. If we can figure out JTAG sooner/more easily, then it is the more valuable option. -wes _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
