Esta página describe como actualizar la imagen del software en su laptop. El procedimiento de actualización crea una llave o disco USB, que cuando es usado para ''bootear'' la laptop OLPC, actualiza el ''firmware'' e instala una nueva versión de la imagen del sistema operativo en la flash NAND.

'''Este proces cambia regularmente, por lo tanto lea las instrucciones con atención.''' Algunos cambios importantes están [[#Important Notes|destacados más abajo]]. El procedimiento básico consta de tres etapas:
# [[#Preparing the hardware|Preparar el hardware]]; 
# [[#Preparing the autoupdate image|Preparar la imagen de auto-actualización]]; y
# [[#Upgrading the machine|Actualizar la máquina]].

La versión del software a usar depende de: la [[#What kind of laptop is it?|versión del hardware a actualizar]] y si se desea usar una versión estable o experimental de desarrollo del software. Las versiones de desarrollo tienen más funcionalidades, pero también más ''bugs'' (a veces grandes). Las [[Test Group Release Notes/lang-es|Notas de Lanzamiento del Grupo de Pruebas]] describe las versiones de desarrollo. Las [[Software Release Notes/lang-es|Notas de Lanzamiento del Software]] describe el estado de los problemas importantes con los que se pueda haber topado anteriormente. La mayoría de la gente con laptops recientes usa la versión estable. Gente con prototipos de la laptop más viejos puede ser que necesiten usar versiones más viejas. Los desarrolladores pueden querer usar versiones más nuevas.

This page describes how to update the software image on your laptop.  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.

'''This process changes regularly, so please read the instructions carefully.'''  Some important changes are [[#Important Notes|noted below]]. The basic procedure has three parts: 
# [[#Preparing the hardware|preparing the hardware]]; 
# [[#Preparing the autoupdate image|preparing the autoupdate image]]; and 
# [[#Upgrading the machine|upgrading the machine]].

The software version you choose depends on: [[#What kind of laptop is it?|what version of laptop hardware you are upgrading]] and whether you want to use a stable version or one of the experimental development versions of the software.  The development versions have more features, but also many more bugs (sometimes big ones).  The [[Test Group Release Notes]] describe the development versions.  The [[Software Release Notes]] describe the status of important software problems you may have encountered previously.  Most people with recent laptops will use the stable version.  People with older laptop prototypes may need to use older versions.  Developers may wish to use newer versions.

==Avisos Importantes==
{{Latest Releases | firmware = inline | extra = inline}}

Si se esta actualizando el ''firmware'', y ocurre algún problem que no se menciona en esta página, <span style="color:red; ">'''no apague la máquina'''</span>; y consiga ayuda de la OLPC, preferentemente por medio de [[IRC/lang-es|IRC]] o por correo electrónico de forma inmediata.

Firmware q2c24 (en las imágenes de auto-reinstalación "2007-08-17 23:10Z" y "2007-08-18 05:08Z") has sido retirado ya que '''puede ''«brickear»'' máquinas B2'''. Por favor, cerciorése de obtener la última versión de la imagen de auto-reinstalación!

La versión de la imagen de auto-reinstalación es mostrada al inicio del proceso de actualización. También se puede encontrar el ''string'' de la versión al principio del archivo de texto <tt>olpc.fth</tt> en el directorio <tt>boot</tt>.

Las versiones más recientes del firmware no soportan las placas A-Test o las máquinas pre-B1. No use este procedimiento si tiene alguna de ellas; contáctese con la OLPC para una actualización.
{{ Translated text | 1=
If you are upgrading ''firmware'', and anything goes wrong which is not mentioned on this page, <span style="color:red; ">'''do not turn off the machine'''</span>; please get help from OLPC, preferably immediately on IRC or by email.

Firmware q2c24 (in autoreinstallation images "2007-08-17 23:10Z" and "2007-08-18 05:08Z") has been withdrawn because '''it may brick B2 machines'''.  Be sure you get the latest version of the autoreinstallation image!

The autoreinstallation image version is displayed at the start of the upgrade process. You can also find the version string at the top of the olpc.fth text file in the boot directory.

Recent firmwares do not support A-test boards or pre-B1 machines.  Do not use this process if you have one of these; contact OLPC for an upgrade.

Comenzando con la imagen de auto-reinstalación "2007-08-15 18:23Z", el procedimiento de actualización realiza una copia de respaldo automática de los datos de usuario antes de actualizar y lo reinstancia al finalizar. La llave USB debe ser los suficientemente grande para almacenar tanto la imagen que se va a instalar, así como también todos los archivos que puedan haber sido creados en <tt>/home/olpc</tt>. '''ADVERTENCIA:''' el procedimiento de actualización anterior '''borraba completamente''' la memoria flash del sistema. Asegúrese de cual es la versión de la imagen de auto-reinstalación que está usando; se puede descargar la imagen más nueva del enlace más abajo si no se está seguro.

A partir de la imagen de auto-reinstalación "2007-08-17 16:35Z" la activación de una máquina previamente no activada después de una actualización ha sido simplificado; vea los detalles abajo.

A partir del '''Build 542''' (firmware Q2C20e), hemos corregido un ''bug'' que se comía llaves USB formateadas como FAT32.
* Por favor, re-descargue la imagen de auto-reinstalación (<tt>[http://dev.laptop.org/git?p=users/cscott/autore;a=blob_plain;f=olpc-auto.zip;hb=HEAD olpc-auto.zip]</tt>) y utilice los nuevos archivos.
* Puede ser deseable reformatear la llave USB o usar un verificador de archivos sobre ella para reparar cualquier anormalidad producida por el viejo firmware.

A partir del '''Build 525''', hemos agregado el paso de activación al procedimiento de actualización.
* Es necesario usar el <tt>'''[http://dev.laptop.org/git?p=users/cscott/autore;a=blob_plain;f=olpc-auto.zip;hb=HEAD nuevo olpc-auto.zip]'''</tt>.
* Debe dejar el disco o llave USB en la máquina después de actualizar, mientras ''rebootea''.
* Note que las rutinas de activación se encuentran solamente en el ''build'', no en el firmware, con lo cual es posible (hasta próximo aviso) mantener el firmware actualizado aún corriendo el Build 406.15, lo recomendado para aquellos con máquinas B2-1 (ej: 128MB).

Starting with autoreinstallation image "2007-08-15 18:23Z", the upgrade process automatically backs up user data before the upgrade and restores it afterward. The USB key must be large enough to hold both the image to be installed and any and all files the user may have created in /home/olpc. '''WARNING''': the old update procedure '''entirely erased''' the flash memory of the system.  Be sure you know which version of the autoreinstallation image you are using; download the newest image from the link below if you are not certain.

As of autoreinstallation image "2007-08-17 16:35Z" activating a previously-unactivated machine after the upgrade has been simplified; see details below.

As of '''Build 542''' (firmware Q2C20e), we have fixed a bug that corrupted USB keys which were formatted FAT32.
* Please redownload the autoreinstallation image ([http://dev.laptop.org/git?p=users/cscott/autore;a=blob_plain;f=olpc-auto.zip;hb=HEAD olpc-auto.zip]) and use the new files.
* You may also want to either reformat your USB key or use a file system checker on it to repair any corruption that may have occurred with the old firmware.

As of '''Build 525''', we have added an activation step to the update process.
* You will need to use the '''[http://dev.laptop.org/git?p=users/cscott/autore;a=blob_plain;f=olpc-auto.zip;hb=HEAD new]''' version of the autoreinstallation image files.
* You must leave the USB flash key or disk in the machine after the upgrade, while it reboots.
* Note that the activation code is only in the build, not in the firmware, so you can (until further notice) keep your firmware up to date while still running Build 406.15, the current recommendation for those of you with B2-1 (ie, 128MB B2) machines.
| display = block }}

A partir del '''Build 406''', se agregó un archivo de ''checksum'' la procedimiento de actualización.
* Se necesita tanto el archivo '''<tt>.img</tt>''' como el '''<tt>.crc</tt>''' para actualizar.

Este procedimiento funciona sobre hardware OLPC reciente:
* La mayoría de las B1 (ver [[#Workaround for old B1 systems|soluciones más abajo]]); y
* Todas las laptops B2, B3, B4 y C.

Solo ha sido probado con Open Firmware:
* Si está usando Linux-as-BIOS o BIOS Insyde, vea la [[#Workaround for LinuxBIOS or Insyde BIOS|solución más abajo]].
{{ Translated text | 1=
As of '''Build 406''', we have added a checksum file to the update process.
* You will need both the '''<tt>.img</tt>''' file and the '''<tt>.crc</tt>''' file to update.

This procedure works for recent OLPC hardware:
* Most B1 (see [[#Workaround for old B1 systems| workaround below]]); and
* All B2, B3, B4 and C laptops.  

It has only been tested with Open Firmware:
* If you are running Linux-as-BIOS or Insyde BIOS, see the [[#Workaround for LinuxBIOS or Insyde BIOS| workaround below]].

{{anchor|Preparing the hardware}}
===Preparando el hardware===
Si usted tiene hardware viejo como (A.B1,B2,B3).. y no sabe si esta corriendo una versión mas vieja que Q2C11 (2007-05-06), necesita comprobarlo. (Al tipear <tt>Alt-=</tt> se abrira la consola de desarrollo, donde la actual versión del firmware esta reportada.) Si usted tiene el viejo firmware, entonces solo presione el boton de prendido/apagado; usted no tiene que presionar el botón "X" de la consola de juego mientras presiona el botón de apagado. (los laptops B4, C, y M tienen un firmware mas reciente que Q2C11)

# Conecte su laptop y asegúrese que su batería este cargada. Es muy importante que el proceso de actualización (que toma casi tres minutos) no sea interrumpido.
# Consiga una USB con al menos 300Mib de espacio libre en la partición primaria.
#* El sistema de archivos debe ser FAT (como un aparato formateado desde fabrica).
#* No tiene que estar particionada, y no funcionara si tiene el código tipo "83" (Linux ext2 o ext3), aun si el actual sistema de archivos adentro de la partición es.

{{ Translated text | 1=
If you have older (A,B1,B2,B3) laptop hardware, and don't know whether it is running a firmware version older than Q2C11 (2007-05-06), you need to check. (Typing <tt>Alt-=</tt> will take you to the Developer's Console, where the current firmware version is reported.) If you do have the older firmware, then just press the power button; you do not have to hold the X game key and press the power button as instructed below. (B4, C, and M laptops have firmware more recent that Q2C11.)

# Plug in your laptop and ensure the battery is charged. It is very important that the update process (Which takes about 3 minutes) not be interrupted.
# Get a USB flash key or disk with at least 300 MiB of free space in the primary partition.
#* The filesystem should be FAT (like a factory-formatted device).
#* It does not have to be partitioned, and will not work if it is partitioned such that the partition type code says "83" (Linux ext2 or ext3), even if the actual filesystem inside the partition is FAT.

#* The image is called '''<tt>osNNN.img</tt>''' ("<tt>NNN</tt>" represents the build number). The checksum file of the same name has the '''<tt>.crc</tt>''' extension.
#* If you are downloading a build earlier than '''Build 530''', the files on the download site will need to be renamed. For instance, if you want to download Build 528, you would download '''<tt>olpc-redhat-stream-development-build-528-20070720_0056-devel_jffs2.img</tt>''', and rename it to '''<tt>os528.img</tt>''', and likewise for its '''<tt>.crc</tt>''' file.

# Copy '''<tt>osNNN.img</tt>''' and '''<tt>osNNN.crc</tt>''' files to the '''<tt>boot</tt>''' directory of the flash or disk drive.
# One of the files in the boot directory should be the latest firmware image, <tt>{{Latest Releases/firmware number}}.rom</tt>.  If the [[Firmware]] page lists a newer firmware release than the one you have, download it to the boot directory.
#* The firmware will be named <tt>qXXXX.rom</tt>, where <tt>XXXX</tt> is the firmware release number in hexadecimal (letters A-F and numbers 0-9).

The <tt>[[Media:sugar-update.txt|sugar-update.py]]</tt> script automates the steps listed above for creating an auto-installation directory and preparing a new image.  This is a python script, and as such requires python to run. ''Important Note: Due to a bug in MediaWiki this script had to be uploaded as a <tt>.txt</tt> file.  Please change the extension to <tt>.py</tt> after downloading.''

; Usage : <tt>sugar-update.py [-'''cdflLqs'''] [-'''b''' build] [directory]</tt>

; Description : This script will create an autoinstallation image boot directory within the specified directory.  If the boot directory already exists, it will only download the necessary image files (<tt>.img, .crc, and .rom</tt>).  Any of these files already present within this <tt>boot</tt> directory will be deleted before the download begins. If no directory is specified, the current working directory will be used.
:This script has also has automatic support for downgrades, and will add the necessary <tt>force.os</tt> file to the boot directory if the build image already present there is newer than the build specified.

; Options :
:<tt>-'''b'''  &nbsp;&nbsp; </tt> Specify a build number; defaults to latest development build
:<tt>-'''c'''  &nbsp;&nbsp; </tt> Create a clean auto-installation image, replacing existing boot directory
:<tt>-'''d'''  &nbsp;&nbsp; </tt> Force downgrade image; implicit when a newer build exists in boot
:<tt>-'''f'''  &nbsp;&nbsp; </tt> Skip firmware update
:<tt>-'''l'''  &nbsp;&nbsp; </tt> Print the associated change log
:<tt>-'''L'''  &nbsp;&nbsp; </tt> Print the change log for the specified build and quit
:<tt>-'''q'''  &nbsp;&nbsp; </tt> Quiet; do not print progress output
:<tt>-'''s'''  &nbsp;&nbsp; </tt> Download the latest stable build; overrides the -b option

; Examples :
: If you're creating a boot directory from scratch, you'll simply want to use:

       sugar-update.py /path/to/USBdrive/

: By adding the -s flag to the above, the latest stable image will be prepared instead:

       sugar-update.py -s /path/to/USBdrive/

: For frequent updates it's useful to show the change log for the new builds:

       sugar-update.py -l /path/to/USBdrive/

{{anchor|Additional notes}}
====Notas adicionales====

{{ Translated text | 1=
* If you have Open Firmware before version Q2C11 (2007-05-06), turn on the power ''without'' pressing a game key.
* If you are upgrading an unactivated machine (prior to Build 542), you may see either a message that says, "Could not activate this XO" followed by the serial number of your machine, or else a XO icon in the center of the display with a lock icon in the bottom right corner. [[Image:Locked_XO.png|right|thumb|Icon displayed when activation fails.]] If this happens: turn off the machine; reinsert the USB key; and hold down the 'X' and 'check' game buttons down while turning the power on. (If your XO is pre-B4 and does not have a 'check' button, use the 'O' button instead.)  Release the buttons when directed. The system should boot into the new system image and perform activation using the activation lease stored on the USB key; '''Do not remove the USB key''' until you've reached the sugar "XO" screen, or the activation process will fail;
* If your USB device is a harddisk instead of flash, you may need to interrupt the Open Firmware boot sequence by pressing the Esc key (the upper left key on the keyboard, marked with an X in a circle), waiting a moment, then entering ''<tt>probe-usb2</tt>''.  You should see additional entries compared to the initial list that Open Firmware displayed. Then you can enter ''<tt>boot</tt>'' and the update should proceed. This is because many external hard drives take a long time to come ready. Recent firmware should fix this issue.
* If the machine does not power on, you need to reset the EC: (a) unplug the machine; (b) remove the battery; (c) wait 30 seconds; (d) reinsert the battery; (e) reconnect power (i.e., plug in the machine); and (f) power on the machine.'''This behavior is expected for machines with Li batteries so be prepared for that'''. Please <span style="color:red; ">'''do not remove the USB key'''</span> until the activation process is completed.
* When removing all power from the laptop, any external USB peripherals should be disconnected, just in case they are faulty and supply current to the system.
* If anything else goes wrong <span style="color:red; ">'''do not turn off the machine'''</span>; please get help from OLPC, preferably immediately on IRC or by email.
* After the upgrade, a backup of your user files can be found on the USB key with the name '<tt>backup/<your XO's serial number>/complete.tgz</tt>'.

* Autenticación fallida! Solucion: apague, reinserte la USB de autoreinstalacion, presione los botones check y X (use el botton 'O' si usted no tiene el botón 'check') y mientras los sostiene prenda. Deje la USB adentro hasta que se vea el ''prompt'' de Sugar para colocar su nombre.
* La imagen en la laptop tienen una imagen superior a la de la USB. Solucion: use [[#Downgrading|downgrading instructions below]].
* Si el disco USB no esta particionado,las imagenes anteriores a la 552fallaran en activarse.
* Es mejor si la USB esta particionada pero:
** El tipo de la partición debe estar en concordancia con el tipo de sistema de archivos; un sistema FAT adentro de una particion marcada como ext2 no funcionara.
** Los archivos del updater deben estar en la partición marcada como "bootable", o si no hay ninguna, en la primera partición.
** Hay una situación donde el disco puede parecer tener una tabla de partición y también un sistema de archivos FAT empezando en el. Aun no somos capaces de soportar esta anómala situación

* Installation failed. Solution: download the new autoreinstallation image ([http://dev.laptop.org/git?p=users/cscott/autore;a=blob_plain;f=olpc-auto.zip;hb=HEAD olpc-auto.zip]) onto a newly formatted USB key and try again.
* Authentication failed! Solution: power off, reinsert the autoreinstallation USB key, hold down the X and the 'check' button (use the 'O' button if you don't have a check button) and while holding them turn the power on.  Leave the USB key in until you get the Sugar prompt to enter your name.
* The image on the laptop has a higher build number than the image on the USB flash. Solution: use the [[#Downgrading|downgrading instructions below]].
* If the USB disk is not partitioned, builds before 552 will fail to activate.
* It is better if the USB disk is partitioned, but:
** 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.
** There is a situation where a disk can appear to both have a partition table and also have a FAT file system starting in the first sector. We are not yet able to support this anomalous situation.
* We have seen some USB disks that take several seconds to detect. In those cases, hold the Game Key for 2+ sec or let the count down expire.
* The main files (<tt>olpc.fth, osNNN.img, osNNN.crc, usbupgos.img, usbupgrd.img, and q2XXX.rom</tt>) must be in the <tt>boot/</tt> subdirectory.
* The current Open Firmware releases do not support USB keys that identify themselves as class "<tt>mass_storage/removable</tt>" &ndash; as opposed to the more common "<tt>mass_storage/scsi</tt>", 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 "<tt>/pci/usb@f,5/removable@1,0</tt>", your disk has the problem.  (If you are running an old version of OFW that does not display the "USB2 devices" list automatically, type "<tt>show-devs /usb</tt>" 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 <tt>fdisk</tt> 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.
* On an ATest board the X Server may fail to start up.  You may need to provide [[Configuring X on an ATest board|a custom configuration]].

=== Solución para LinuxBIOS o Insyde BIOS ===

{{ Translated text | 1=
If you are running LinuxBIOS, this process will probably not work (it has not been tested).  The [http://wiki.laptop.org/index.php?title=Autoreinstallation_image&oldid=49797 old version of this procedure] may work for you.

If you are still running Insyde BIOS, you will first have to upgrade the firmware using procedures described '''[[Upgrading_to_LinuxBIOS|elsewhere]]'''.

{{anchor|Workaround for old B1 systems}}
=== Solución para viejos sistemas B1 ===

{{ Translated text |
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  "netnandwrite" tool.  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:
# Insert the autoupdater key;
# boot up the laptop and when it says "<tt>Press a key to interrupt</tt>" then press any key;
# at the Ok prompt type "<tt>flash disk:\boot\{{Latest Releases/firmware number}}.rom</tt>".  The machine will turn off when finished.
# power up again and boot the autoupdater normally; (It will reflash the NAND with the new build.)

<b>Note: DO NOT DOWNGRADE Q2Cxx firmware to Q2Bxx firmware.</b> This will destroy the manufacturing information. For details, see [[Firmware]].

If you tried to load a build that is older than the one currently installed on your XO, then you will have gotten a message that the software is up to date. Follow this procedure to load an older version:

{{anchor|Automatic downgrade}}
====Volver automáticamente====

{{ Translated text |
Note: I don't believe this method works (the force.os didn't work for me). I have updated the manual version.

# Download the <tt>osNNN.img and osNNN.crc</tt> files for the old build into the <tt>boot/</tt> directory of your autoreinstallation key.  Make sure that the boot directory contains both the <tt>osNNN.img and osNNN.crc</tt> files to which you are downgrading, but not any newer os image.
# Create a new file in the <tt>boot</tt> subdirectory with the name '<tt>force.os</tt>'. (It does not matter what is in it; it just matters that the subdirectory exists and has that name.) This will cause the autoreinstallation script to try to install the image in <tt>boot/</tt>, regardless of whether it is older or newer than the current build on your XO.
# Follow the standard [[#Upgrading the machine|autoreinstallation procedure above]].

{{anchor|Manual downgrade}}
====Volver manualmente====

{{ Translated text |
You can also downgrade by using the copy-nand command at the OK prompt.
 copy-nand u:\boot\os525.img

After the copy, you need to activate your laptop:
# reboot the machine holding the 'X' and 'check' game-pad keys; (If your XO does not have a 'check' key, use the 'O' key.)
# leave the USB stick in while it writes the activation code.

(Note that automatic backup of user files will fail with this technique.)

{{anchor|Reinstalling the same image}}
====Reinstalando la misma imagen====

{{ Translated text |
If you want to reinstall the *same* image you've currently got, you should find an earlier '''stable''' build, use the downgrade procedure, and then the standard upgrade procedure to your new image.

{{anchor|Resetting the EC}}
===Reseteando al CE===

{{ Translated text |
There is a capacitor on the reset line of the EC that controls how long the reset signal is asserted.  This capacitor is the wrong value so the reset timing is invalid.  This means that when you reset the EC with the power enabled there is a good chance it will not boot correctly.

If the EC does not reset correctly then the laptop will not start. Any laptop that is earlier than CTest may have this problem.

The only way to guarantee that the EC is fully reset after you upgrade the firmware is to power it off.  The only way to really power off the EC is to remove the external power and the battery.  Even when the power to the laptop CPU is off the EC is still powered.  The capacitors in the system will hold their charge for several seconds after you remove power.  You have to wait 10 seconds to make sure that all the capacitors have discharged.

The reason you do not remove the USB disk is that when the laptop powers off the upgrade procedure is not finished. You still have to boot with the USB disk so that it updates the OS image.
