Upgrading firmware: Difference between revisions

Revision as of 18:33, 7 January 2008

Advanced users: To do unsafe firmware upgrades you have to have developer key. If you lose power during a firmware upgrade you will brick the laptop.

1. Make sure your battery is charged.

2. Plug up the XO on external power.

Steps 1 and 2 are NOT optional. The XO will not upgrade system firmware unless it has a battery and external power.

3. Open the Terminal activity

4. Type the following (press the Enter key after each line):

wget http://dev.laptop.org/pub/firmware/q2d07/bootfw.zip
su -
cp bootfw.zip /versions/boot/current/boot/
reboot

Step 4 can also come from a USB key if you don't have networking available. Plug in the USB key and locate bootfw.zip (should be under /media/name_of_usb_key, where name_of_usb_key is the name of your usb key when you formatted it -- a PC or Mac will display the name once the usb key is plugged in). Then type the following (press the Enter key after each line):

su -
cp /media/name_of_usb_key/bootfw.zip /versions/boot/current/boot/
reboot

5. The laptop will then reboot twice more on its own. (Once to enable writing to the flash and then a 2nd time after its done updating.)

The XO will only upgrade the system firmware if it finds that the current version is earlier than whats in bootfw.zip
