La Fonera is a really nice toy. I have already deacivated serial console because of playing with IR receiver. So why not playing with serial 128*128 LCD ? Read the rest of this entry »

Using DIY IR receiver with GNU/Linux is quite simple. All you need is a TSOP receiver, a diode, a resistor and a78L05 regulator as explained here. But this wont work with USB/serial adapter and it need a kernel module to directly drive DCD line.
But there is Paul Fox's avrlirc project, using AVR Attiny2313 to connect IR receiver to the serial RX line. It can be used with USB/serial and embedded system with simple serial port like... La Fonera.

There is a new Fon router : La fonera+ (plus). This router is quite similar than the classical Fonera except that's it include two ethernet interfaces. This can be very usefull for a lot of things. Can OpenWrt Kamikaze 7.07 run on Fonera+ ? Yes, but not well. Here is my first try...

Update from OpenWrt Kamikaze 7.06 to 7.07 give a lot of good things. One of them is linux 2.6.21.5. The driver for the i2c bus adapter using GPIO need update. Here is.

While trying to update my Fonera to d'OpenWrt Kamikaze 7.07, i got :
Can't locate c0000(786432) bytes free in FLASH
In others words : unable to allocate 786432 bytes in flash memory, not enough space. There is a kernel size problem with openwrt-atheros-2.6-vmlinux.lzma. Olds OpenWrt Kamikaze kernels are 720896 bytes long (0xB0000) but news ones are bigger : 786432 bytes long (0xC0000). We need to play with RedBoot's images directory.

The goal for my first try to use Fonera's GPIO is to get i2c working on the router. And now, it's done. Kernel module and user space programs are here.

La Fonera is a nice router. Small, open, white... and with ugly green leds on the front. Really bad ! Fonera with white or blue leds may be too expensive to product but nicer. Let's correct the problem. Here is La Fonera with white leds.

You can use code injection and/or fake Radius server to gain root (SSH) access to La Fornera. But there is a much simple way : connecte your computer to the console port inside the Wifi router :
