OLPC Firmware B2 Production Release Q2B51 - 2007-01-26

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.

Changes since Q2B43

  • EC: PQ2B51
    • Update to a new charging algorithm from the battery manufacturer.
    • Fixed a bug where the charging LED would stay lit while the battery was removed.
    • Fixed a bug where removing and then re-inserting the same battery would cause the reported battery capacity to be different.
  • OFW svn commit 132
    • Added OLPC ec-version and ec-name properties in the root node.
    • Added cpu/x86/pc/olpc/msrscan.fth, a tool for checking MSR settings.
    • Added OLPC touchpad diagnostic to build
    • OLPC trac #833: Adjusted boot icon sizes and changed the wraparound strategy so that the logo is not overwritten.

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
  • 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.
