  * The [http://git.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=summary official u-boot source code] already has support for the S5PC110 SOC(system on a chip) that the Nexus S uses 
  * The S5PC110 has a bootrom 
  * The Nexus S has an usb port with an FSA9480 behind it

  * Serial console: 
   * Use the correct resistors enabling the serial console on the FSA9480 
   * Mesure the voltage of the Nexus S serial port 
   * Make a level shifter to shift the serial port levels  
   * Cross compile microcom or picocom  
   * get a serial console
