Talk:Upgrading firmware
If I have a XO from the G1G1 program in 2007, can I update it with the newest July and August firmware and software? -- stickster at gmail dot com
- Yes, but as the page says, you'll need a dev key. If you are not feeling adventurous, you might want to wait a few weeks for the signed build that gets declared as the 8.2 release, there should be plenty of documentation about how to upgrade to that. cjl 23:46, 23 August 2008 (UTC)
Using only your XO
XO-1.5 in this case.
If you upgrade to a new release, your firmware will be updated automatically.
Nevertheless I'm interested to upgrade the firmware without upgrading the extant 12.1.0 system.
cd /versions/boot/current/boot/
No /versions/boot/current/boot/ here. It has /versions/running/boot/ and /boot/. Starting with the X game key down ignores /versions/running/boot/bootfw.zip and /boot/bootfw.zip. System 12.1.0 boots as usual.
http://wiki.laptop.org/go/Forth_Lesson_12 inspires me to consider this.
ok printenv boot-device
ok ( Carefully note the long value of boot-device to restore later. )
ok setenv boot-device int:\boot\bootfw.zip
ok reboot ( Assuming it exists. Otherwise power-off and boot. )
After the upgrade
ok setenv boot-device ... ( Restore value noted earlier. )
Advices?
