OpeniBoot is an open source implementation of iBoot for Apple iPhone and iPod Touch devices. It allows booting of unsigned code such as linux kernels on the device. There is also and OpeniBoot console (oibc) which can be connected to from a libusb enabled computer. Jaywalker's OpeniBoot is critical for the booting and usage of linux on the iPhone as it sets up and initializes many devices ready for the linux kernel to take over. Many iBoot functions are replicated here, however when booting iOS iBoot is chainloaded from the NOR to guarantee iOS will boot without problems even with OpeniBoot installed.


Latest Version of OpeniBoot : 0.2

3. Compile all in client/:

Code:


  cd client && make all && cd ..      
  

(requires libusb, libreadline and pthread)

4. Launch openiboot, using the menu on the device

5. Run the client:

Code:


  sudo client/oibc


6. Copy the openiboot binary in the device memory:

Code:


  !openiboot.bin


7. Jump to it:

[/code]go 0×09000000[/code]

8. Relaunch openiboot console using the menu on the device.

I got interrupts to work for the 2g ipod touch openiboot. See http://github.com/kleemajo/iphonelinux for the source (reboots after 10s).


GUIDE UPDATE : Ok when switching to kleemajo's git repository since he is a few commits ahead of Jaywalker.
