I'm having problems to enable the Battery charger on my custom Board (Running Windows CE 6.0)
The problem is that the charge current is only about 45mA@3.77V (I'm setting the Charger to 500mA, having a stable +5V Supply with up to 1.25A)
The HW_POWER registers are:
BatteryVoltage = 3776
DieTemperature = 41
Charge Current: 0x28
HW_POWER_CTRL = 0x7054C
HW_POWER_5VCTRL = 0x2403F117
HW_POWER_MINPWR = 0x40
HW_POWER_CHARGE = 0x128
HW_POWER_VDDDCTRL = 0x2071D
HW_POWER_VDDACTRL = 0x270C
HW_POWER_VDDIOCTRL = 0x270A
HW_POWER_VDDMEMCTRL = 0x230
HW_POWER_DCDC4P2 = 0x80C20018
HW_POWER_MISC = 0x0
HW_POWER_DCLIMITS = 0x305F
HW_POWER_LOOPCTRL = 0x167021
HW_POWER_STS = 0x21178A2E
HW_POWER_SPEED = 0x800
HW_POWER_BATTMONITOR = 0x1D60E00
HW_POWER_RESET = 0x0
HW_POWER_SPECIAL_RD = 0x0
I somebody is so kind to take a look at my register settings and pointing me to the error, i would be very glad.

Solved! Go to Solution.
Thanks Igor
After some more test's i change the HW and magically the charger started working, I have probably broken the charger circuit on my 1. Board.
Thank's for Your help

Hi Martin
reason may be that 4P2 LinReg and battery charger both share the 5 V current, while
4P2 LinReg is having priority, details for setting charger current is described in
attached app note sect.5 Battery Charging Subsystem.
