==Introduzione==

Quella che segue è una descrizione passo-passo di come aggiornare il firmware del Neo utilizzando FLUID. Tenete presente che questo procedimento non permette quasi nessuna modifica, continuate a vostro rischio e pericolo. Le istruzioni sono basate su un messaggio di Werner (http://lists.openmoko.org/pipermail/openmoko-devel/2008-April/002605.html), grazie.

Attenzione: L'aggiornamento alla versione MOKO9-beta del firmware non è raccomandato da OM e probabilmente non risolverebbe nessuno dei problemi recenti come il bug [http://docs.openmoko.org/trac/ticket/1024 #1024] ed altri.

Per immagini più recenti del firmware controllate all'indirizzo http://people.openmoko.org/joerg/calypso_moko_FW

Leggete il file http://people.openmoko.org/joerg/calypso_moko_FW/all_version__CHANGELOG.txt per le note di versione.

Attualmente è disponibile la versione firmware moko10, che dovrebbe risolvere il bug #666, ed inoltre implementa un nuovo comando AT+CSIM.
Questa versione non si propone di risolvere il bug [http://docs.openmoko.org/trac/ticket/1024 #1024]
Stiamo progettando di includere questa versione del firmware nella versione di fabbrica dell'A7.

Consigliamo di non aggiornare il firmware seguendo questa guida fino a quando non si padroneggia completamente la riga di comando, inoltre controllate di non digitare erroneamente nessun comando di FLUID!
Presto ci sarà un'immagine per schede SD che semplificherà decisamente l'intero processo di aggiornamento, per questo suggeriamo, a tutti quelli che non si sentono sicuro di procedere, di aspettare la messa a punto di un metodo migliore (la versione beta è a fine pagina).

'''Attenzione: se si pasticcia con i comandi di FLUID c'è la possibilità di rendere definitivamente inutilizzabile il modem GSM. Controllate quello che scrivete!'''

Il firmware GSM del GTA01 è identico a quello GTA02, così come l'hardware; per questo motivo è possibile installare MOKO10 (o qualsiasi altro firmware più aggiornato) sul GTA01.
Secondo mwester, la procedura permette anche di aggiornare da MOKO1 su GTA01Bva a MOKO10b2.

Qualsiasi contributo su aggiornamenti andati a buon fine, sui problemi riscontrati durante la procedura di aggiornamento o sulle SIM che funzionano dopo l'aggiornamento sono estremamente graditi.

==Fase 1: Preparativi==

* Scaricare e installare una distribuzione che permetta l'accesso SSH al dispostivo. Raccomandiamo l'immagine fso-console:
<pre>
mickey@amethyst$ cd /tmp
mickey@amethyst$ wget http://people.openmoko.org/mickey/images/openmoko-fso-console-image-glibc-ipk--20081028-om-gta02.rootfs.jffs2.summary
mickey@amethyst$ dfu-util -a rootfs -R -D ./openmoko-fso-console-image-glibc-ipk--20081028-om-gta02.rootfs.jffs2.summary
mickey@amethyst$ wget http://people.openmoko.org/mickey/images/uImage-2.6.24+r10+gitr75999+54524f4531c8b262431b794fea610d81bb351c86-r10-om-gta02.bin
mickey@amethyst$ dfu-util -a kernel -R -D ./uImage-2.6.24+r10+gitr75999+54524f4531c8b262431b794fea610d81bb351c86-r10-om-gta02.bin
</pre>
* Installare http://people.openmoko.org/joerg/calypso_moko_FW/fluid_0.0+svn20070817-r2_armv4t_eabi.ipk sul dispositivo:
<pre>
root@om-gta02:~# opkg install http://people.openmoko.org/joerg/calypso_moko_FW/fluid_0.0+svn20070817-r2_armv4t_eabi.ipk
</pre>
* Installare http://people.openmoko.org/joerg/calypso_moko_FW/s3c24xx-gpio_1.0+svnr4130-r2.1_armv4t.ipk sul dispositivo:
<pre>
root@om-gta02:~# opkg install http://people.openmoko.org/joerg/calypso_moko_FW/s3c24xx-gpio_1.0+svnr4130-r2.1_armv4t.ipk
</pre>
* Scaricare nella cartella /home/root http://people.openmoko.org/joerg/calypso_moko_FW/gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-moko10.m0:
<pre>
root@om-gta02:~# cd $HOME
root@om-gta02:~# wget http://people.openmoko.org/joerg/calypso_moko_FW/gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-moko10.m0
</pre>

==Fase 2: Lobotomia==

* Assicurarsi che '''nulla''' stia utilizzando il modem GSM. If you're using the fso-console image from the link above, this will happen automagically on boot. On other systems, kill processes as you see fit.

* Powercycle the modem:
<pre>
root@om-gta02:~# echo 0 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
root@om-gta02:~# echo 1 >/sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
root@om-gta02:~# s3c24xx-gpio b7=0
root@om-gta02:~# echo "AT@POFF" >/dev/ttySAC0
</pre>

* Launch the FLUID binary:
<pre>
root@om-gta02:~# cd /usr/sbin
root@om-gta02:/usr/sbin# FLUID_PORT=/dev/ttySAC0 FLUID_FLOWCONTROL=h fluid.exe \
-oO -b 115200 \
-f $HOME/gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-moko10.m0
</pre>
It should say something like this (takes a few seconds to load the file):
<pre>
FLUID Revision 2.27, ...
Bootloader: (reset target)
</pre>
(if this fails repeatedly, or flashing aborted and you have a broken and "bricked" gsm-firmware due to this, try -oo instead of -oO, to use the calypso ROM bootloader instead of the firmware bootloader. Also try without the 'FLUID_FLOWCONTROL=h' part, there are reports on ROM-bootloader not working with hardware-flowcontrol. Changing the -b to some lower baudrate might improve stability of flashing-process - the bootloader does autobaud, so you're free to use any rate)

* Start a second SSH session and start the modem:
<pre>
root@om-gta02:~# s3c24xx-gpio b7=1
</pre>

FLUID should now say something like this (it will take a couple of minutes to finish):

<pre>
(fluid, version 3) ok
Checksumming (269 * 8kB = 2152kB): ok
Flash Detect: (0xEC, 0x22A0) Samsung K5A3240CT ok
Program: (34 sectors, 267*8k=2136k) (*******************) ok
</pre>

'''Note: If you get this instead: MESSAGE: File cmd.m0 not found, then you didn't do the ''cd /usr/sbin''. Please pay attention ;-)'''

If FLUID does nothing, curse your bad luck and repeat the reset sequence, this is the whole 'echo 0/1, b7=0/1 stuff'.

* To verify that everything went well, do this in either of the two sessions:
<pre>
root@om-gta02:~# cat /dev/ttySAC0 &
root@om-gta02:~# echo -en 'AT\r' >/dev/ttySAC0
root@om-gta02:~# echo -en 'AT+CGMR\r' >/dev/ttySAC0
+CGMR: "HW: GTA, GSM: gsm_ac_gp_fd_pu_em_cph_ds_vc_cal_amd8_ts0-Moko10"
root@om-gta02:~# kill %1
</pre>

In some case you may receive this:

<pre>
(fluid, version 3) ok
Checksumming (269 * 8kB = 2152kB): ok
Flash Detect: (0xEC, 0x22A0) Samsung K5A3240CT ok
Program: (0 sectors, 0*8k=0k) () ok
</pre>

If so reflash some older firmware that can be found here (http://people.openmoko.org/joerg/calypso_moko_FW/) -- but never downgrade to a version earlier than Moko6, or you will render the GSM unusable (certain internal data structures changed between Moko5 and Moko6).
Also PLEASE DON 'T USE moko9beta1, as there is at least one report on reflashing to another FW gets difficult from moko9b1.

==Troubleshooting==

Some users weren't able to complete the upgrade since they got an error while the firmware was uploading in the GSM chip (like ''Flash operation timeout'').

However a solution [http://n2.nabble.com/problems-with-calypso-firmware-update-tp1565196p1566012.html has been found] and it allows to use again the GSM modem.
(please note this topic resides on [http://lists.openmoko.org/pipermail/devel/2008-November/003150.html devel-ML]. Don't spread over multiple lists please, as it won't help in getting a response to your request just in time, and most people following the main thread likely will miss your postings anyway)

Use the following fluid command:

<pre>
FLUID_PORT=/dev/ttySAC0 fluid.exe -oo -b 115200 -f $HOME/gsm_ac_gp_fd_pu_em_cph_ds_vc_cal35_ri_36_amd8_ts0-moko10.m0
</pre>
(Without FLOWCONTROL and with -oo to choose the ROM bootloader)

Then on a ''second ssh session'' please use this instead of the gpio command:
<pre>
echo 0 > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
echo 1 > /sys/bus/platform/devices/neo1973-pm-gsm.0/power_on
</pre>
The firmware download should start now.

== uSD-card Image ==
There's a beta version for flashing MOKO11 to GTA02 Freerunner only.
* Download and untar http://people.openmoko.org/joerg/calypso_moko_FW/moko11/flash-moko11_uSD-image.tar.gz .

* (apply `sudo` or use root-terminal according to your taste ;)
* Insert a uSD to your PC, `umount` all uSD-partitions that might have been automounted (use `mount` or `df -h` to check). Do not use "safely remove" for this.

* `dd` the image "flash-moko11-2.image" to the physical(!) uSD-device (this will erase all data from your uSD!). `Sync` or `eject <device>`.

* Insert uSD to your FR, boot from NOR-U-Boot to uSD, wait until green "d_o_n_e" shows on screen (takes some 6min). Remove bat and uSD, or login via ssh. `mickeyterm` will access modem.
