Hello! I'm working with imx233 with 2.6.31 kernel. The board refuses to start a kernel when I plug a fully charged Li-ion battery (4.2V). When I plug a 3.9 battery, kernel loads OK.
PowerPrep start initialize power...
Fix power pin.
Battery Voltage = 4.15V
boot from battery. 5v input not detected

I would suggest you to try U-boot 2013.07 and a kernel 3.10.

Hello! The kernel 3.10 has no sound support. I need to rum kernel 2.6.31 and bootlets. How to correct the power prep bootlet to boot from >4,0V battery?
