Here is the right place. Some discussions are on this list as well as on the 
Openmoko community list.

The last case "It didn't boot" means: not the bootloader either, after 
replacing the uSD? 
My bootloader, or maybe the touchscreen driver, seems to crash sometimes as 
well. In some cases I can prevent it from freezing by connecting the USB after 
the bootloader screen has been visible for a couple of seconds. I have no 
proof that it is not a coincidence though, so don't start running circles at 
full moon to get it to boot, once your battery is full ;-)

I expect the phone being connected to your system via USB, while working on 
the uSD, or was it just lying around? As long as it keeps charging, USB 
provides enough power to run the phone and charge the battery.

This is what tail -f /var/log/messages tells while turning on and showing the 
bootloader screen:
Oct 22 21:38:31 tp kernel: [345675.170991] usb 1-1.2: new full-speed USB 
device number 7 using ehci_hcd

Without the battery inserted the screen flashes, but to short to give any 
output via USB.

I don't have a flat battery at the moment; this morning the phone would not 
boot from the bootloader screen at first try. Now it did, though I 
disconnected USB while the system prepared for the bootloader screen, I then 
tapped "boot from uSD" , connected USB and tapped "boot from uSD" again. Then 
it booted, giving these entries in /var/log/messages on my laptop:

It is what Benjamin wrote: keep it connected, it will trickle-charge for quite 
a while, than start flashing the screen on and off, until it accumulates 
enough charge to reach the bootloader screen. 

If I recall correctly, the bootloader screen got enough intelligence to ask 
for a higher current (and charge faster). I'm not sure about that anymore 
though (it was in Radeks bootscreen documentation, but I can't find it at the

Maybe one more thing: do you have an Openmoko charger, or another high(er) 
power charger? That will charge your battery faster than a USB port of course, 
but besides that, the powermanagement chip seems quite picky about the current 
it receives from the host. Alexander has given a list of creative ways of 
discharging the battery (which I could not find eiter, but I found another 
more to the point discussion about power at boot up: 

Good luck!
