Automatic Reinstallation Image

This page describes how to update the software image on your laptop. This process changes regularly, so please read the instructions carefully. Important changes are noted below. The update procedure creates a USB flash key or disk that when booted on an OLPC laptop, updates its firmware and installs a new version of the operating system image onto NAND flash.

WARNING: The update procedure will entirely erase the flash memory of the system. Be sure to backup any user-space files onto an external device before reinstallation.

The Software Release Notes document the status of the most important issues of this software.

The Test Group Release Notes describe the status of development versions of the software.

In most cases, the system will boot automatically after the firmware or disk image is updated.

Posibles Problemas

• The filenames you chose for the build images violate the 8.3 character restriction for FAT filesystems. Solution: use shorter filenames.
• The image on the laptop has a higher build number than the image on the USB flash. Solution: use copy-nand as per the instructions below.
• It is better if the USB disk is not partitioned. If it is partitioned:
  • The partition type must agree with the filesystem type; a FAT filesystem inside a partition marked ext2 won't work
  • The updater files should be in the partition that is marked as "bootable", or if there isn't one, in the first partition.
• The main files (olpc.fth, osNNN.img, osNNN.crc, and q2XXX.rom) must be in the boot/ subdirectory.
• The current Open Firmware releases do not support USB keys that identify themselves as class "mass_storage/removable" -- as opposed to the more common "mass_storage/scsi", which is supported. (A fix for this problem is in the release pipeline, but that doesn't help for upgrading from existing firmware.) The way to check for this is to insert your USB key, power-on the system and stop the auto-boot by typing the Esc key (upper left key) at the countdown. Then look at the list of "USB2 devices". If you see an entry like "/pci/usb@f,5/removable@1,0", your disk has the problem. (If you are running an old version of OFW that does not display the "USB2 devices" list automatically, type "show-devs /usb" to see the list.) The workaround procedure is below.
• The current firmware also fails with USB devices whose hardware sector size is not 512 bytes. To determine the sector size of your device, you can use fdisk on the device under Linux, and it will tell you when it first accesses the device if the sector size is not 512. The workaround is the same as for the "removable" problem, i.e. the procedure below.
• Many Multi-Function devices do not work.
• If during the upgrade you see the following message, try renaming the file olpc.7th in the boot directory of the update image to olpc-boot.7th.

Trying startup script disk:\boot\olpc-boot.7th
Can't open boot device

• On an ATest board the X Server may fail to start up. You may need to provide a custom configuration.

Solución para los viejos sistemas B1

If you have a B1 system that has never been upgraded, it is very important to use this page's Autoreinstallation procedure for your first update; do not try to use the new "netnandwrite" tool first. The reason is that this procedure automatically fixes a manufacturing error in the identification data that was stored in the system firmware FLASH, and updates the firmware, neither of which is done by the network-based tool. Also, some old firmware will not update with the auto-update script. If the standard procedure above doesn't update, instead, follow these steps:

1. Insert the autoupdater key;
2. boot up the laptop and when it says "Press a key to interrupt" then press any key;
3. at the Ok prompt type "flash disk:\boot\q2c18.rom". The machine will turn off when finished.
4. power up again and boot the autoupdater normally; (It will reflash the NAND with the new build.)

Des-actualizando

Note: DO NOT DOWNGRADE Q2Cxx firmware to Q2Bxx firmware. This will destroy the manufacturing information. For details, see Firmware.

If you are trying to load a build that is older than the one on the XO, you will get a message that the software is up to date. Follow this procedure to first load an older version and then try the upgrade again:

1. In this example you have already loaded build 528 and need to try loading the same one again. Find an earlier build such as 515 (known to be good). Download the .img and .crc files onto a USB stick. They can be at the root but the two files have to be in the same directory.
2. Boot up the laptop by pressing the power button and hold down the gamepad X button.
3. When the message asks you to stop pressing it, let go.
4. Then press the escape key when it gives you 3 seconds to stop the rest of the boot.
5. From this OK prompt you should be able to type: copy-nand u:\nand515.img (use the full path if you didn't copy it into the root.)
6. Assuming that started correctly you will end up with a 515 build. You can power down and then proceed to upgrade with the newer files on your usb stick for the new upgrade procedure.

(Note: After you've downgraded you might want to remove the 515 build from your USB stick, especially if you put it on the \boot directory of your usb stick. It is important that you have the correct .fth, .img, and .crc in the boot directory of the usb in order to upgrade properly with activation. Having more than one .img in there might cause problems.)
