Oh, that would be a very elegant solution. Since the level shifter is operating only in the CPU -> modem direction, there should be no risk of the modem accidently keeping GSM_2V8 up. > requirements of the GE865.

It's rather strange that they don't export a few mA of that juice for level shifters. - Werner _______________________________________________ gta02-core mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/gta02-core
