This firmware is the second test candidate for the Update.1 software release set.
Download: q2d09.rom
[edit] Changes since OLPC Firmware q2d08
[edit] OpenFirmware is svn 785
- The selftest suite (rocker left) now displays battery info and manufacturing data.
- The "just in case" firmware write protect that occurs before game-button functions is now only done if the wp tag is present.
- OLPC trac 6080 - Fixed bug in mfg data tag scanner that was causing the keyboard driver to crash with a stack underflow when looking for the KA tag in a mfg data area that had been corrupted with a malformed long-data tag.
- The x86 assembler/disassembler now handles 16-bit mode better
[edit] WLAN firmware is 5.110.20.p49.bin
<same as in previous release>
[edit] EC code is d08b
Need release notes.
[edit] Which Firmware Do You Have?
If your machine is not in secure mode, the firmware version is displayed in the startup banner, as in:
OLPC B4, 256 MiB memory installed, S/N SHF7250024D OpenFirmware CL1 Q2D07 Q2D
If your machine is in secure mode, you can go to the Terminal activity and type
cat /ofw/openprom/model
If your machine is in secure mode but the OS will not start, just go ahead and try to upgrade the firmware anyway. The procedure is safe and will not do anything if you already have up-to-date firmware.
Beginning with firmware Q2D08, you can see the firmware version in secure mode by powering up with the "check" game button held down.
[edit] Installation
When installing new firmware, you need a well-charged battery and the AC adapter must be plugged in. The firmware update code will not proceed otherwise.
[edit] Unsecured Machines
(Please note that most developer machines are "unsecured". To unsecure your machine, follow the instructions at Activation and Developer Keys.)
First download the firmware from http://dev.laptop.org/pub/firmware/q2d09/q2d09.rom.
You can download on another computer with the above link. To download on the XO, go to the terminal activity and type something like
cd /versions/boot/current/boot/ wget http://dev.laptop.org/pub/firmware/q2d09/q2d09.rom
If you want to use a USB or SD drive to store the firmware before installing, replace the first line above with:
cd /media/disk mkdir boot cd boot
Put the q2d09.rom file on the XO NAND FLASH filesystem in /versions/boot/current/boot/q2d09.rom, or on a USB key as /boot/q2d09.rom . Power cycle the system and press the Escape (top left key) to get to the ok prompt. Then type either:
ok flash u:\boot\q2d09.rom ( if the file is on a USB key )
if you are copying the firmware from a Windows machine, 1)Make sure the USB key is formatted for FAT and not
FAT32, and 2)don't use a \boot directory. Just u:\q2d09.rom
or
ok flash n:\boot\q2d09.rom ( if the file is on the NAND FLASH filesystem )
or
ok flash n:\boot-alt\q2d09.rom ( if the file is on the NAND FLASH in the alternate boot filesystem )
or
ok flash sd:\boot\q2d09.rom ( if the file is on an SD card )
(Use the "dir" command if you need help finding the file.)
This will only work if the XO has a well-charged battery AND is plugged in. "AC not present" means you need to plug it in.
[edit] Secured Machines
Secure-mode machines can only use flash firmware that has been signed. All mass-production machines have the latest signed firmware so far, and pre-mass-production machines are almost all unsecured.
See Cheat codes for information about how game buttons control startup options.
