Is that supplemental info available somewhere? The sensible thing to do is raise a minimal system and then power up units one by one. Isn't ARM fully static? i.e. could i have the cpu running from rom and some sram in bits and bouts when "switched off"? I'le read up a bit and then come back to you if I have a good idea. uwe _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
