But higher voltage will add to the heat issues of the device. La Fonera comes with an I.T.E. Power Supply Model MU12-2050200-A1. This power supply has a 5.5mm outer diameter and 2.5mm inner diameter plug with tip-positive / ring-negative polarity. You can get a cheap replacement [[http://dx.com/p/ac-power-adapter-for-wireless-router-surveillance-security-camera-5-5x2-5mm-us-plug-100-240v-101106|here]]. |
| FON2200: 7.5V (small connector) - Internally this is regulated to 3.3V by a switched regulator, so it will probably work on anything from 4 to 16V, without adding to heat. A 12V supply voltage is proved to work. | FON2200: 7.5V (small connector) - Internally this is regulated to 3.3V by a switched regulator, so it will probably work on anything from 4 to 16V, without adding to heat.

Below, replace the two IP address placeholders with something that applies to you. The first IP in the command, "IP address of the server", is the IP address of the TFTP server that you have running that will serve the OpenWRT images to La Fonera. The second IP in the command, "IP address for the router" is only temporary, it must be a free IP address in the same subnet as the TFTP server. If you are connected to RedBoot via Telnet, set the "IP address for the router" to the IP address that you telneted to (192.168.1.254). The switch //-l// is for //local//. |

| + | ==== Disabling serial console ==== | ||
| + | |||
| + | Easy hack to disable serial console without recompiling kernel, unpack vmlinuz.lzma, search for console= and replace with null and spaces using mfill in redboot. Also comment out /dev/ttyS0 in /etc/inittab. This is fconfig for Backfire 10.03.1 : | ||
| + | |||
| + | <code> | ||
| + | RedBoot> fconfig -l | ||
| + | Run script at boot: true | ||
| + | Boot script: | ||
| + | .. fis load -l vmlinux.bin.l7 | ||
| + | .. mfill -b 0x802B3FF8 -l 4 -4 -p 0x6E756C6C | ||
| + | .. mfill -b 0x802B3FFc -l 6 -1 -p 0x20 | ||
| + | .. exec | ||
| + | Boot script timeout (1000ms resolution): 10 | ||
| + | Use BOOTP for network configuration: false | ||
| + | Gateway IP address: 0.0.0.0 | ||
| + | Local IP address: 192.168.1.1 | ||
| + | Local IP address mask: 255.255.255.0 | ||
| + | Default server IP address: 192.168.1.10 | ||
| + | Console baud rate: 9600 | ||
| + | GDB connection port: 9000 | ||
| + | Force console for special debug messages: false | ||
