OLPC Firmware Release q2c09 - 2007-04-30

This is development firmware for the BTest boards. It will also work on ATest. Do not use it on pre-B1 boards - it will brick them because of the EC microcode.

Warning! Warning! BIG FAT WARNING! The manufacturing data has moved locations. If you are upgrading from the B series of the firmware the manufacturing data will be moved to its new location. After that has happened you must not install anything from the B series of the firmware. If you do then you will erase your manufacturing data.

Installation Instructions

  • If you have a B1 or B2 system:
    • Detailed upgrade instructions are located here.
    • If your firmware version is earlier than the version in Auto Install Image then you can just use that procedure for the update.
      Note: that this procedure will also upgrade the image in your nand flash -- which is the entire Linux operating system and all the files you may have edited or saved. This means it will ERASE what is in your nand and re-write it. So you will lose any data you have stored on the filesystem unless you back it up. If you do not want your files erased, then please use the first procedure above.
    • Do NOT use olpcflash to write new firmware images. Doing so will erase the manufacturing data that was added at the factory.
    • After you reflash, you must power cycle by physically removing power from the system. A warm-start or button-induced restart is not sufficient. Please remove both the battery pack and wall adapter for 10 seconds.
  • If you have an ATest system
    • If you use olpcflash to write this image, you must use the --brick option.
      Example: olpcflash --brick -w image.rom
      The --brick option makes olpcflash update your EC code as well as the firmware.
