LaFonera SD Card Hack

Caution

JFFS is enabled in 0403 and later builds. As of April 6, 2007 no SD/MMC module has been ported.

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. On the other hand, [1]Here you can find ipkg-packages for Kernel 2.4 and 2.6 readymade for the MMC-Hack on the Fonera.

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
