#ipkg install http://downloads.openwrt.org/snapshots/ixp4xx/packages/huaweiaktbbo_1_armeb.ipk

# ipkg install ppp openvpn chat openntpd

# ipkg install http://downloads.openwrt.org/snapshots/ixp4xx/packages/hwclock_2.13.0.1-2_armeb.ipk

• And let configure them:

# vi /etc/ntpd.conf

server 193.204.114.232
server 193.204.114.233
server ntp1.inrim.it # or a ntp server near you
server ntp2.inrim.it # or another ntp server near you
listen on *

# /etc/init.d/ntpd disable

# /etc/init.d/ntpd start

• We use a bridge configuration for network, edit /etc/config/network and add this line in eth0 section:

option type ‘bridge’

• Copy gprsd.sh in /usr/scripts
• Copy gprsd in /etc/default and edit it
• Copy custom-user-startup into /etc/init.d/

# /etc/init.d/custom-user-startup enable

• run # crontab -e and add

*/3 * * * * /usr/script/gprsd.sh checkrunning &

• copy chat and peers directory into /etc/ppp
• Copy openvpn into /etc
• Edit /etc/default/openvpn, add “ENABLED=1” and change config file
• Edit /etc/init.d/openvpn, add “ENABLED=0″ and this to start () function:

if [ "$ENABLED" != "1" ] ; then
echo “$BIN disabled, check $DEFAULT”
exit 0
fi

• run #/etc/init.d/openvpn enable
• bla bla bla (nice in openvpn.conf)

Set your time zone (with web interface is easier )

Disable Web interface (we don’t need it ):

# /etc/init.d/webif disable

# /etc/init.d/httpd disable

• Change the hostname:

# vi /etc/config/system and edit the “option hostname” line

• Fresh our installation:

# ipkg update && ipkg upgrade

• Install kernel modules for usb support:

# ipkg install kmod-usb2 kmod-usb-storage kmod-usb-ohci kmod-usb-serial

• Install kernel modules for some cellular (Motorola, Samsung,…):
  

# ipkg install kmod-usb-acm

• Install kernel modules for some USB modem (Huawei E220):

# ipkg install kmod-usb-serial-option

• Install any other kernel modules for (almost) all serial converter (such usb modem):

# ipkg install kmod-usb-serial-visor kmod-usb-serial-sierrawireless kmod-usb-serial-pl2303 kmod-usb-serial-mct kmod-usb-serial-ftdi kmod-usb-serial-belkin kmod-usb-serial-airprime

• Install kernel modules for usb disk:

# ipkg install kmod-nls-cp1250 kmod-nls-utf8 kmod-nls-base kmod-fs-vfat

• Install useful package:

# ipkg install usbutils pciutils minicom ntpclient

• Add this line into start() function of /etc/init.d/boot:

echo 0 > /sys/class/leds/status/brightness
echo 0 > /sys/class/leds/ready/brightness

Connect network cable

etch:~/nslu2/709# upslug2
NSLU2     00:14:bf:70:dc:86 Product ID: 1 Protocol ID: 0 Firmware Version: R23V63 [0x2363]

• Now upload the downloaded image:

etch:~/nslu2/709# upslug2 -i openwrt-kamikaze-7.09-nslu2.bin

• The ouput should end with:

Rebooting… done

• Now, if you have a DHCP server enabled on your network, Nslu2 take IP address from it.

NSLU2 has one serial port with TTL signal-level (3.3V), for more information read this.

I don’t want to see anything outside the nslu2 (only the connector itself) so i’ve looked for a microchip that doesn’t need anything else than RX-TX and power supply.

So i found MAX3233 (datasheet), it’s fantastic! You need only one 0.1uF capacitor for spurious power supply (really, i don’t use it ).

Here is the tipical schematic of MAX3233 from www.maxim-ic.com:

As you can see we can have up to two serial port, and no need of external capacitor.

Starting opening our nslu2 and looking near battery. You can see four unused hole, this one is RS232 pins (looking image 1).

The first one (near battery) is 3.3 V, the second one is RX, third is TX and fourth is GND. Take 4 piece of cable and:

- connect pin 1 of nslu2 to pins 5-9-10 of MAX3233;

- pin 2 with pin 1 of MAX3233;

- pin 3 with pin 3 of MAX3233;

- pin 4 with pin 18 of MAX3233;

Now you can solder also the serial connector, pin 5 is ground so connect it with pin 18 of MAX3233.

Assuming that you are using a male connector you have to solder pin 3 of DB9 with pin 19 of MAX3233 and pin 2 of DB9 to pin 20 of MAX3233. If you use a female connector (only for console) simply invert pins 2 and 3 onto DB9 connector.

Fon2200 SD/MMC reader

I’m going to describe how to connect an MMC card (with an home-made reader) to new Fonera.

This new model is tagged with FON2200 and have a new board design, different from the old one (FON2100).
