Firmware

  This page is monitored by the OLPC team.

This firmware goes in the little 1 MB SPI flash that's used for booting, not the 1GB NAND flash (or 512MB in earlier prototypes) used for the OS image and user data. The SPI flash contains the Embedded controller ("EC") firmware, Open Firmware, and 2k Manufacturing Data. See Firmware SPI FLASH Map or its dia source file.

Updating the firmware

Upgrading the XO to a new release usually updates both the firmware in the SPI flash and the operating system software in the NAND flash. Users should update to the latest stable release to get the latest stable versions of both.

Users can also upgrade only their XO's firmware to the latest official (signed) firmware, see Upgrading firmware

Developers who have an unsecured laptop or a developer key have more options.

• They can install any of the firmware releases below; click the firmware's name for instructions.
• They can alter the secure upgrade to use one of the firmware files below.
• There is also
  • a manual update procedure for the SPI flash
  • C source code for a self-hosted Linux flash writer (may destroy the manufacturing data)
  • instructions for flashing via Open Firmware
  • a recovery procedure that requires the use of a serial cable and external oscillator.

Note: Once you upgrade to the Q2Cxx series of firmware do not downgrade to Q2Bxx! Doing so will destroy the manufacturing data. Downgrading from Q2F01 to Q2C01 will "Brick" your XO-1 :-(
