Installation Caveats

  • If you use olpcflash to write this image, you must use the --brick option.
  • After you reflash, you must power cycle by physically removing power from the system. A warm-start or button-induced restart is not sufficient.

Known issues

  • Auto-repeat is slow on some USB keyboards
  • NVRAM storage for configuration variables is not yet implemented.
  • JFFS2 does not pay attention to the bad block table.
  • JFFS2 does not handle ECC
  • The boot menu is incomplete
  • Dirctory symlinks have a problem.
