Freerunner won't boot: dies in uboot

2009-06-27 Thread Chris Wright
My Freerunner was acting fine until yesterday. Now, it refuses to boot
while not connected to a USB charger -- the power button does nothing.
When connected, it starts booting, but stops and turns off about five
seconds after showing the splash screen or uboot menu.

This happens when I boot into the NAND or the NOR bootloader. It
happens if I wait at the menu. If I go to the menu, I can start
booting the kernel, and I get as far as Starting kernel... and the
screen turning white (depending on how fast I am with the menu) before
the phone turns itself off.

I can do this many times, so I don't think it's a battery issue (also
since the bootloader usually detects whether it's connected to power
and starts charging, so I can just chill at the boot menu for an hour
and then boot like normal -- that's not happening now). I don't have
the wall plug, though, so I can't try that.

I've browsed the mailing list archives for something like this and
haven't found anything. Any suggestions on how to determine what is
wrong?

Can you check the voltage of the battery? When it's full, it should
have over 4 V. Look at this page for more hinst:
