LaFonera SD Card Hack
Warning!
As of this writing (Mar 4, 2007), GPIO is not enabled on La Fonera.
Purpose
It would be nice to be able to attach a SD Card to the LaFonera for storage.
MMC driver for the LaFonera
A kernel module is required in order to use the MMC hack. Using Rob Wentworth MMC drivers for OpenWRT or compile these using the toolchain on your LaFonera.
SDIO Pinout
Pinout of the LaFonera according to http://kwzs.be/~kevin/ar531x/gpio%20pinout.txt
GPIO Pin on LaFonera 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
Cheap SD Card "reader" (floppy cable)
http://uanr.com/sdfloppy/ describes how to build a SD card reader from an old 5.25 floppy drive connector. The description is for WRT but maybe this could be used with LaFonera too.
Bastard Sons of Dial-Up Episode 8 (http://BSoDtv.org/episodes.php) explains how to make an SD Card PCB.
There is a video on making a Floppy Drive SD Card Connector for embeded devices here: http://bsodtv.wiihost.net/Simple%20SD%20Card%20Connector.avi
Existing SD Card hacks for other devices

- Also, there is a SDIO stack from Atheros http://source.mvista.com/~dsingleton/sdio … SDIO-linux which besdes SD cards also intends to support "SDIO USB" which sounds even more interesting :-)
