Firmware

  This page is monitored by the OLPC team.

Introduction

The firmware of the XO laptop is the software that runs before and during the operating system.

Updating - For Users

Updating the XO to a new operating system release updates the firmware, if required. Normally, users should update to the latest stable operating system release in order to update the firmware.

However, users may upgrade just the firmware to the latest signed release.

Updating - For Developers

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

• install any of the firmware releases below; click the firmware version for instructions.
• alter the secure upgrade to use one of the firmware files below.

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 :-(

Brick Recovery

Updating using the methods above requires working firmware. If the firmware is not working, and the laptop is bricked, the options are:

• a recovery procedure for updating the SPI FLASH chip using another system, and
• a replacement procedure for the SPI FLASH chip.

Both these require electronics lab bench skills and service tooling.

Firmware Releases

The latest release is the first in the list. There is a list for each laptop model. Do not mix firmware between models; it should not install, and it would be harmful if it does install.

WARNING! XO-1.75 Firmware will NOT work on an XO-1 or an XO-1.5.
