I would like to see the Motorola chargers working too, without having to modify the charger. It seems that it's some other resistance, maybe 200k. What is the tolerance? Does the Freerunner actually measure the resistance? If we modify the code to be more tolerant (any resistance between 20K and 500K means a charger is being detected, and 500mA should be OK, whereas if it's 47K we can charge at 1A) could the phone be distributed with this modification? Where is this code which does the measuring, is it the PMU firmware or it runs on the main CPU? _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
