Oh, yeah I've forgotten to precise that it won't charge even with the
hw-validation debian on NAND (I've not flashed the last one, so it's the
version of end 2012, normally with the 2.6.32 kernel).

After that I've these values :

So it doesn't make any difference. I don't think it's a QtMoko bug,
because last week it worked well before the SHR test and it doesn't work
with the hw-validation debian on NAND. I don't understand really well
what's the problem.

For information, below, the same values when I'm able to charge my phone
with the external battery and the good usb cable after having plugged
during resume of a suspend (with screen locked) :
