Introduction

This explains how to:

  • Easily lower the voltage of an arduino
  • Use that arduino to flash a coreboot image on a GM45 Thinkpad with a SOIC16 chip

It requires:

  • An AVR Arduino at 5v
  • An USB<->Serial adapter capable of providing enough current to power up:
    • The arduino
    • The flash chip
    • The circuits around the flash chip

It was tested with:

  • An arduino.org "nano version 3.3"
  • A Ssparkfun "FTDI Basic 3v3" (Uses an FTDI FT232R)
