  For the general public

Purpose

An update to 10.1.1 synchronised across both XO-1 and XO-1.5 hardware.

Installation

The build is installed to the internal storage. You will need a USB memory stick of at least 1Gb capacity, but only for the duration of the installation.

ALL USER DATA WILL BE ERASED FROM THE LAPTOP!

• Prepare the USB memory stick:
  • Identify your laptop model as either XO-1 or XO-1.5,
  • Download each of the files from the table below,
  • Save each file to the top directory of a USB memory stick,
  • Check the USB memory stick contains at least the files listed.

laptop model	files required
XO-1	os301.img and os301.crc
XO-1.5	not yet available, use Release_notes/10.1.1

• Prepare the laptop:
  • Make a copy of any data you wish to keep,
  • Ensure the battery is in the laptop,
  • Connect the laptop to external power,
  • Turn off the laptop, unless it is already off,
  • Insert the USB memory stick into any USB port on the laptop,

to be verified ... at the moment the os300 build has no fs.zip file, so you must obtain use an unlocked laptop and the copy-nand command instead of the following procedure ... see F11_for_XO-1#Installation

• Start installing:
  • Hold down all four game keys (see this in pictures),
  • Turn on the laptop,
  • Wait for the message Release the game keys to continue,
  • Release the game keys.

Installation progress will be displayed. Green colour will fill grey blocks. It will take about ten minutes. Once finished, the laptop will reboot. Remove the USB memory stick during or after the reboot. The USB memory stick can be used on other laptops.

If you see a message Boot failed then either:

• the USB memory stick has not been properly prepared, or;
• the firmware is out of date and should be updated (see Firmware).

Upgrade

For XO-1, an upgrade using olpc-update from 8.2.1 os802 is not available.

For XO-1.5, as an alternative to installation, you may wish to upgrade from a previous version of the XO-1.5 operating system. This method preserves most user data, Sugar journal and installed Sugar activities, but does not preserve certain operating system customisations such as additional packages.

Since activities are not updated, several known problems will remain. Most but not all of these can be fixed using Software update.

To use this method, establish an internet connection, then type on the Terminal:

sudo olpc-update 10.2_xo1.5-127   # updating to build 127 of 10.1.1

A few previous versions do not support this method.

New features

to be completed

Known Problems

XO-1.5 No screen rotation

The screen rotation key (on the bottom left of the display) does not rotate the screen image. It is safe to use, but makes no change.

Developers are working on rotation support in the graphics driver. (<trac>9350</trac>)

XO-1.5 Record activity video recording may pause

When recording a video of a very complex natural scene, such as moving vegetation, in High quality, the recording may pause. If this happens, reducing camera movement may allow the laptop to catch up. Alternatively, switch to Low quality and try again.

XO-1.5 Record activity preview black on lid close and open

With the Record activity on screen displaying a preview of the camera image, closing the laptop lid for long enough to cause a suspend, and then opening it, results in the preview going black.

If this happens, the preview can be restored by pressing Alt/Tab, or switching between Sugar views using the keyboard keys or the frame icons.

The black preview does not affect the taking of photographs, or recording of video. If a video recording is being made, there will be a segment of time missing in the playback.

Developers are aware of the problem. (<trac>10068</trac>)

XO-1.5 No NANDblaster

NANDblaster, a technology used to install OLPC OS releases on large numbers of laptops simultaneously, did not make it into this release. A development version is working. This feature is a high priority and we expect to finish it soon. (<trac>9484</trac>)
