[edit] OLPC Firmware Release q2d16 - 2008-05-29
This firmware is a bug-fix release that is going to manufacturing concurrently with the manufacturing release of OS 708 or thereabouts.
Download: q2d16.rom
Download: Signed Q2D16 bootfw.zip
It supersedes q2d14. q2d15 was an unreleased test build.
[edit] Changes since OLPC Firmware q2d14
[edit] OpenFirmware is svn 830
- r830 - The "enter" client service refuses the ok prompt in secure mode
- r829 - The memtest command now works on a secured laptop with a developer key
- r828 - Disable indexed-I/O during early interaction (trac 7114)
- r823 - Commented-out CMOS RAM control of PLL and memory settings, so bad CMOS RAM values won't prevent startup.
- r821 - Removed a confusing error message "buffer@<address>"
- r819 - Prevent a firmware crash from an obscure keystroke command
(The svn checkins that are not listed were for components that do not affect the OLPC build, or for file rearrangements that don't change behavior.)
[edit] WLAN firmware is 5.110.22.p1
<Need>
[edit] EC code is pq2d13
<Same as q2d14>
[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.
Beginning with OS Build 690 (or less?) you can also goto the main screen and click on the little man and select "about this XO"
[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/q2d16/q2d16.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/q2d16/q2d16.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 q2d16.rom file on the XO NAND FLASH filesystem in /versions/boot/current/boot/q2d16.rom, or on a USB key as /boot/q2d16.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\q2d16.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:\q2d16.rom
or
ok flash n:\boot\q2d16.rom ( if the file is on the NAND FLASH filesystem )
or
ok flash n:\boot-alt\q2d16.rom ( if the file is on the NAND FLASH in the alternate boot filesystem )
or
ok flash sd:\boot\q2d16.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.
