Changes since Q2A42
- EC update to A51
- OFW: Some nand write fixes for spurious errrors
- OFW: Flash preserves mfg data
- OFW: Sets keyboard type in CMOS RAM based on manufacturing data
- OFW: Network is enabled - works with Ax88772 and Ax8817x USB ethernet chips
- OFW: Boot process polish - color icons, speedups, function key handling, less screen flashing
- OFW: USB STALL fixes - some USB devices (e.g. keyboards) that used to fail now work
- OFW: Serial and kbd/screen console now work simultaneously
- OFW Compilation process: Fixes to make gunzip work with gcc 4
- OFW Compilation process: Built from open source svn upstream instead of from tarball
Installation Caveats
- 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.
BTest-1 users should NOT use olpcflash to write new firmware images. Doing so will erase the manufacturing data that was added at the factory.
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.
ATest -- Infineon RAMs only
Thise is a special purpose image. Do not use except on A-test boards with Infineon RAMS.
