Changes since Q2B11

  • LinuxBios: Correct buggy attempt to fix errata 57
  • LinuxBios: Turn off unneeded clocks in the USB controller
  • LinuxBios: Change a lot of printk_err to be the priority warning or debug
  • LinuxBios: Check straps to look for a BTest2 and if found then set the clock divisor up for 66Mhz.
  • OFW: Net device is not first in boot order
  • OFW: Mods to make device tree exportable.

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.

ATest -- Infineon RAMs only

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