|||
=== 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.<br> Example: <code>olpcflash --brick -w image.rom</code><br> 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.''' |
