Description
La Fonera est un routeur, composé d'un chipset Atheros (jusqu’à 54Mbits), d'une mémoire flash de 4Mo et d'une RAM de 16Mo, fonctionne grâce au système openwrt avec un noyau Linux 2.4. Il est vendu par FON pour créer une communauté d'accés wifi dans le monde.
La Fonera est surtout un sytème embarqué sous Linux pas cher qui permet de dévelloper ces propres applications grâce à OpenWrt.
Firmware FON
La version actuelle sur cette Fonera est la 0.7.2r3. Il existe plusieurs méthodes logiciels sur internet permattant d'accéder à une connexion ssh, mais celles-ci sont destinées a des versions de firmware plus anciennes.
L'autre méthode et de passer par le port série interne de la Fonera.

Le port est configuré avec le format séri: 9600-8N1
Connecteur série

Les signaux RXD and TXD sont sous (3.3V), non comptatible avec les niveaux RS232.
Il faut une interface pour les adapter à un port série de PC.
Exemple d'interface de type Max3232 pour adapter les signaux TTL 3.3V aux signaux RS232 (-12V/+12V) d'un PC.

Developper des programmes pour La Fonera
Contruire OpenWrt à partir de sources
http://forum.openwrt.org/viewtopic.php?pid=45838
- Télécharger les sources
svn co https://svn.openwrt.org/openwrt/trunk/ svn co https://svn.openwrt.org/openwrt/packages/ trunk/feeds/packages/ cd trunk/ make package/symlinks
- Configure Kamikaze (select target system) and the packages (a full build with all packages selected requires about 9GB of free disk space)
make menuconfig
- If you select extra packages it's a good idea to check if you have all prerequisites installed. Check with:
make prereq
TIP: To find the missing packages search at http://packages.ubuntu.com/
- Finally build Kamikaze (to download all packages at once use 'make download world')
make world
- After the build finished, ready to use images can be found in $(TOPDIR)/bin
Targets for 'make'
download
download all source tarballs (from the selected packages and it's dependencies) at once before starting the build
prereq
checks if you have all prerequisites installed on the host-system for building the selected packages
world
build everything
tools/install toolchain/install
only build the tools and the toolchain
clean
cleans the packages (NOT the tools and toolchain)
distclean
cleans up everything expect $(TOPDIR)/.config and $(TOPDIR)/dl/
package/<package_name>-{clean,compile}
rebuild a single package
package/index
updates $(TOPDIR)/bin/packages/Packages
V=99
turns on debugging
make kernel_menuconfig
If you want, you can also modify the kernel config for the selected target system. Simply run "make kernel_menuconfig" and the build system will unpack the kernel sources (if necessary), run menuconfig inside of the kernel tree, and then copy the kernel config to target/linux/<platform>/config so that it is preserved over "make clean" call.

GPIO de La FONERA
Ces sont les ports d'entrées/sorties du routeur. Certains sont libres d'utilisation.
Utiliser les entrées sorties GPIO sur la Fonera
Source du module proc_gpio
Un module kernel a été créé pour donner accès au GPIO.
Celui-ci est disponible sur ce lien: http://fghhgh.150m.com/ et en mirroir ici: gpio.tgz
GPIO Description
Bit Fonctions 0 TP3 1 pin 5 of SW1 2 WLAN LED 3 pin 1 of SW1 4 pin 2 of SW1 5 RESET (!) 6 RESET button 7 pin 6 of SW1
Utilisation
Lancement du module:
# insmod proc_gpio.ko # lsmod Module Size Used by proc_gpio 2704 0
Etat des entrées/sorties:
# cat /proc/gpio/info GPIO_IN 0X7FFF20 GPIO_OUT 0X000020 GPIO_DIR 0X000020
Test en dés/activant la led WAN:
# echo 1 > /proc/gpio/2_dir # echo 1 > /proc/gpio/2_out => WLAN LED on # echo 0 > /proc/gpio/2 => WLAN LED off
Test des entrées/sorties libres pour utilisation:
