Hi all,

I need to get battery voltage, but both of "/sys/class/power_supply/battery/uevent" and HW_POWER_BATTMONITOR.BATT_VAL bits have wrong values (~4200mV). Also when the battery is disconnected (and it reboots), it is still appears that battery is present.

Any answer will be appreciated.

Regards,

Sinan

   Please check if Your schematic (regarding battery using) is the same as the i.MX28 EVK.

Also, please verify if corresponding software (driver) configured correctly.
Driver details may be found in Chapter 27 [Battery Charger and Power Source Manager
(PSM) Driver] of "MX28_EVK_Linux_Reference_Manual.pdf".

Have a great day,
Yuri
