MD5: 11c14240aa81eaefa74c48131f5f3d51 olpc-Q2A71.rom

Changes since Q2A63

  • EC: update to A71
  • EC: Implement matrix button repeat scan code
  • OFW: Update to SVN 60
  • OFW: Added USB net device id 0b95,7720
  • OFW: Fixed memory layout for virtual-mode support. Virtual support

has now been tested/working, but is not turned on in this version.

  • OFW: Removed unused EGA console support hooks.
  • OFW: Dialed back to 60 Hz refresh on VGA, as that seems to be the most widely supported.

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

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