OLPC Firmware B2 Release Q2B73 - 2007-02-16
This is the firmware for the B2 boards. It will also work on B1 and ATest. Do not use it on pre-B1 boards - it will brick them because of the EC microcode.

Changes since Q2B61
- EC: PQ2B73
- Add new mechanisms to determine when the battery is not behaving as expected and disable charging.
- Communication to the battery results in all zeros.
- The voltage from the monitor IC in the battery has not changed for 4 minutes during a charge/discharge.
- Bugfix: Temperature of battery shows 256'C (0xFF).
- Bugfix: Battery shows fully charged but actual battery capacity is only 10 minutes.
- Bugfix: Battery data not updated if the touchpad is constantly busy.
- Change LED be solid red when battery low rather than blink
- Add new mechanisms to determine when the battery is not behaving as expected and disable charging.
- OFW svn commit 161
- SDHCI: Handle DMA boundary crossings.
- OLPC: Added battery status display
- OLPC fastboot - support for 66 MHz (B2 and later) systems.
- OLPC VSA-less (fastboot) configuration: fixed edge/level settings for IRQs, thus resolving the problem with EHCI (USB2) not working reliably.
- Linux Makefile: Added -m32 to CFLAGS for compilation on 64-bit systems.
- OLPC touchpad diagnostic: added relative tracking mode and raw packet display feature.
- sdhci.fth: The Marvell SDHCI implementation won't turn on the card power if a card removal notification is pending, so clear that notification before turning on power. Also turn on power before trying to detect the card.
- Fixed problem with Kensington USB keyboards not working - OLPC trac #539.
- OLPC sdhci driver: Added high speed SD card support.
- Report total OLPC memory size in the memory node reg property and thus the banner, without subtracting the frame buffer and the memory used by things like VSA.
Installation Caveats
- If you have a B1 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.
