It means that the USB ID pin doesn't have a level identified as a charger (obviously as you have USB plugged in) and that no voltage is detected on the USB power pins. Just for completeness sake, you can check the contents of the charger_adc file with USB supply as well as with charger supply. With charger supply it still reports 'none' for charger type. The first thing I would check would be how far into the Neo you can measure voltage, starting from the USB connector. This is mainly to check that it isn't simply a broken connector at fault. If there's 4-5 V all the way to the PCF50633 PMU, then it's likely something inside the PMU that's been zapped. I don't think I have the tools to measure that far in, but at least I can tell that the voltage reaches the FreeRunner end of the connector. At that point the wires disappear into the circuit board and I'm not sure where to follow them. The second thing I would check, if there is no voltage at the USB connector, is if the Neo is drawing current at all from the USB host. If it is, chances are one of the two reverse- and overvoltage protectors have shorted. I'm not sure how to measure this, but from the host I can at least tell that the phone negotiates 500mA successfully. usbfs/devices reports: T: Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#= 25 Spd=12 MxCh= 0 D: Ver= 2.00 Cls=02(comm.)

Well, it's easiest to see when plugged in to the computer, and that reports 500. More worryingly, charger_type in that dir says: none mode 500mA To me, that means it can tell that 500mA is available, but that it can't/won't give it to the battery. Forcing fast charge mode just changes the 500mA to 1A, but doesn't change anything else. It just seems like something has been zapped in the FreeRunner (since it used to work fine), and the bits that would actually pull current across the usb port aren't working. Just for kicks I tried opening it up but didn't see any obvious melted parts... hey, you never know, it might be something easily visible! Any other ideas? If it is a hardware fault then I'm not sure who would even be able/willing to fix it. Steve ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support
FR works but can't charge battery
Hi. I hope someone can help here... My FreeRunner can't charge its battery. Even when plugged in to USB or the wall, the phone can't/won't charge. Eventually the battery discharges completely and although I have an external charger, this isn't good. I've also verified the same problem with a friend's Nokia BL-5C battery, so it seems to be something wrong in the FreeRunner. When ssh'ed in over USB, when I cat: /sys/devices/platform/bq27000-battery.0/power_supply/bat/uevent I get: POWER_SUPPLY_NAME=bat POWER_SUPPLY_TYPE=Battery POWER_SUPPLY_STATUS=Discharging POWER_SUPPLY_VOLTAGE_NOW=422 POWER_SUPPLY_CURRENT_NOW=171750 POWER_SUPPLY_CHARGE_FULL=1122051 POWER_SUPPLY_TEMP=243 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TIME_TO_EMPTY_NOW=23700 POWER_SUPPLY_TIME_TO_FULL_NOW=3932100 POWER_SUPPLY_CAPACITY=96 POWER_SUPPLY_ONLINE=0 The phone used to charge fine. I've tried reflashing to FSO milestone 4 and the most recent FDOM with no differences. I haven't tried anything newer, but it doesn't really sound like that would make much of a difference. The only thing I can sort of correlate to it breaking is when I started using one of those car USB adapters to charge the phone in the car. So that might have broken something (?), but what are the odds that this is fixable? Who might be able to diagnose or repair it? I really hope there's something I can do because without the ability to charge or even run from the wall, this FreeRunner is pretty much useless. Thanks for any help.
