OLPC Firmware Pre-Production Release Q2B15 - 2007-01-02

This is the firmware for the pre-production test build of the B2 boards.

File:Olpc-Q2B15.rom

MD5: 0a1e413f0801d1fa1a1cd3ca402c736a


Changes since Q2B14

  • LinuxBios: The 33/66 MHz switching code was accidentally omitted in B13 and B14, and has been reinstated in B15.

Installation Caveats

  • If you have a B1 system:
  1. Perform the auto-reinstall procedure at http://wiki.laptop.org/go/Autoreinstallation_image before upgrading to this firmware version
  2. 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.

ATest users only: If you use olpcflash to write this image, you must use the --brick option.
Example: olpcflash --brick -w image.rom
This will update your EC code.

Known issues

  • Auto-repeat is slow on some USB keyboards
  • NVRAM storage for configuration variables is not yet implemented.
  • JFFS2 does not handle ECC
  • The boot menu is incomplete
  • Dirctory symlinks have a problem.


The ATest/Infineon RAMS variant of this firmware version has not been released.
