I have a question for Battery + 5V operating in i.MX23.
I modified the boot stream to be operated with Low Battery and 5V power.
For this, I just enabled DCDC_4P2 for Low Battery and 5V Power in boot stream.
For your more understanding, I'll attached the modified boot stream file, power_prep/power_prep.c
But Kernel was used Battery when the Power source was "Low Battery + 5V".
So the board was power-off when I plug-out 5V USB Power Cable and the kernel was not operating on very low battery.
Could you tell me how to use 5V as power source when the power source is "Low Battery + 5V"?
And then I want to charge the Battery.
