I understand. Is this hardware related? Just for curiosity, from a design perspective why wouldn't or shouldn't the hardware/software start drawing 500mA and then fall back to 100mA if not available ? > > > >On Nov 15, 2007 12:21 PM, Jean-Michel Bouffard > ><[EMAIL PROTECTED]> wrote: > >> -----BEGIN PGP SIGNED MESSAGE----- > >> Hash: SHA1 > >> > >> > >> You can always force the charger to pull the 500ma with this command: > >> echo -n "fast_cccv" > > >> /sys/devices/platform/s3c2410-i2c/i2c-adapter/i2c-0/0-0008/chgmode > >> > > > >Will this work with a motorola razr charger, which seems to provide > >550mA.
