OLPC Firmware B2 Production Release Q2B32 - 2007-01-23

This is the firmware for the production build of the B2 boards. It will also work on B1 and ATest. Do not use it on pre-B1 boards - it will brick them because of the EC microcode.

Installation Caveats

  • If you have a B1 or B2 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
  • Directory symlinks have a problem.

ATest -- Infineon RAMs only

This is a special purpose image. Do not use except on A-test boards with Infineon RAMS.
