We were using u-boot, kernel and rootfs images from http://people.openmoko.org/werner/devirginate-20070301.tar.gz to pre-install the devices. This is a self-contained devirginator snapshot, and can be used at any given time to fully restore the phone (complete loss of data is implied). This is how to restore the phone:
Download to the Linux PC that will do the installation.
Go to a convenient directory, then
tar xfz devirginate-20070301.tar.gz
Enter the directory:
cd devirginate-20070301
Disconnect everything:
- the USB connector of the debug v2 board from the PC
- the USB cable from the Neo
- remove the battery
Connect the Neo to the debug v2 board.
Connect USB of the debug v2 board to the PC.
If you have a serial console, start it now. The device should be something like /dev/ttyUSB0.
Connect the USB cable of the Neo.
Insert the battery.
Power on the Neo. (If it has powered on by itself, that's okay.)
Start OpenOCD (if you have a local openocd.cfg, please use that one):
tmp/openocd -f tmp/openocd-debugv2.cfg
OpenOCD should print one line (below) and keep running:
Info: openocd.c:84 main(): Open On-Chip Debugger (2007-01-31 12:00 CET)
If OpenOCD prints an error, please disconnect the USB cable of debug v2 from the PC, connect it again, then restart OpenOCD.
In another window, start the install script:
./devirginate -0 -1 -2
NOTE: The -0 option irrecoverably destroys bad block information provided by the chip manufacturer. This is only appropriate for devices from phase 0, or earlier. Instructions will be updated for later models. |
Watch the screen of the Neo. The following things should happen:
- it turns on, showing weird things for about 10-30 seconds
- the screen goes dark for 1-2 minutes
- the screen lights up and shows a smiling face for a few minutes
- the screen goes dark and shows a partial (broken) OpenMoko logo for about 5-10 seconds
- the screen goes dark again, then shows the full OpenMoko logo
- the machine will boot Linux now and start touch screen calibration
Errata
- u-boot can power-off the phone while in DFU mode
