Dump the whole contents of I2C device at 7-bit address 0x50 on bus 9 (i2c-9), using the default read method (byte mode), after user confirmation:
$ i2cdump 9 0x50
Immediately dump the whole contents of I2C device at 7-bit address 0x50 on bus 9 (i2c-9), using I2C block read transactions (no user confirmation):
$ i2cdump -y 9 0x50 i
If the device is an EEPROM, the output would typically be the same as output of the previous example. Dump registers 0x00 to 0x3f of the I2C device at 7-bit address 0x2d on bus 1 (i2c-1), using the default read method (byte mode), after user confirmation:
$ i2cdump -r 0x00-0x3f 1 0x2d
Dump the registers of the SMBus device at address 0x69 on bus 0 (i2c-0), using one SMBus block read transaction with error checking enabled, after user confirmation:

External Routing using Host PC as Gateway @alienmind
In order to ping google server 8.8.8.8 from board routed to Host PC you have to setup first board side using route command:
$ route add default gw 10.0.0.1 netmask 255.255.255.0 eth0
Then from Host PC side you have to setup the right routing using:
#Internet (can ping google)
SRC=wlan0
#Local routing (Board<-->Host)
DEST=eth0
#Refresh ip-table
sudo iptables --flush
sudo iptables --table nat --flush
sudo iptables --delete-chain
sudo iptables --table nat --delete-chain
#Setup routing ip-table
sudo iptables --table nat --append POSTROUTING --out-interface ${SRC} -j MASQUERADE
sudo iptables --append FORWARD --in-interface ${DEST} -j ACCEPT
sudo iptables -A FORWARD -i ${SRC} -o ${DEST} -m state --state RELATED,ESTABLISHED -j ACCEPT
sudo iptables -A FORWARD -i ${SRC} -o ${DEST} -j ACCEPT
sudo su -c "echo 1 > /proc/sys/net/ipv4/ip_forward"
$ wlan0 up $ wlan0 scan $ iwlist scan
Required packages --> [wpa_supplicant | ip | iw | ping]
$ iw dev $ ip link show wlan0 $ ip link set wlan0 up $ ip link show wlan0 $ iw wlan0 link $ iw wlan0 scan | grep -i ssid $ wpa_passphrase WIFI-GUEST WIFI-GUEST-PW > /etc/wpa_guest.conf $ wpa_supplicant -i wlan0 -c /etc/wpa_guest.conf -Dwext & $ udhcpc -i wlan0
To do the test is necessary hostapd installed on your fs, first change /etc/hostapd.conf and put the preferred configuration:
interface=uap0
ssid=pi-5G
macaddr_acl=0
ignore_broadcast_ssid=0
## 2.4G
#hw_mode=a
#channel=7
## 5G
hw_mode=a
channel=0
country_code=US
ieee80211d=1
ieee80211n=1
ieee80211ac=1

## wpa auth
auth_algs=1
wpa=2
wpa_passphrase=11111111
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
Now turn on uap0 interface:
$ ifconfig uap0 up
Then enable and start hostapd.service:
$ systemctl enable hostapd.service
$ systemctl start hostapd

$CARD is the card name listed by pacmd list-cards (for example, alsa_card.platform-sound-cs42888.34 in the
example above), and $PROFILE is the profile name. These are also listed by pamcd list-cards . (for example,
output:analog-surround-51 in the example above).
After setting the card profile, use $ pactl list sinks and $pacmd set-default-sink $sink-number to set
the default sink.
