OLPC Firmware B2 Production Release Q2B21 - 2007-01-14
This is the candidate firmware for the production build of the B2 boards. It will also work on B1 and ATest boards.
MD5:
a4d80cd69dc06929a917bd291b5d312d olpc-Q2B21.rom
Changes since Q2B18
- OFW: Update to r94
- OFW: Updated NAND timings
Installation Caveats
- If you have a B1 or B2 system:
- Perform the auto-reinstall procedure at http://wiki.laptop.org/go/Autoreinstallation_image before upgrading to this firmware version
- 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.
