Connect a MMC or SD card memory

This article explains how to connect a MMC memory card (or SD memory card in SPI mode) to the FOX Board.

Wirings

Just 4 signal lines + power supply are needed to connect a MMC/SD card to the FOX Board.

The following extension boards have this schematic already implemented:

FOXZB XBee/RS485 add-on board
FOXZB is an add-on board to adapt a MaxStream XBee module, a RS485 bus, a MMC/SD memory card, a Sensirion SHT71/75 humidity and temperature sensor and a Real Time Clock circuitry with Li-ion battery
GPS and GPRS application kit for M2M FOX based projects
FOXGPS and FOXGPRS includes all parts you need to design your own M2M application based on the FOX Board LX

Configure the FOX Board SDK to install the MMC/SD Kernel module

From the devboard directory type:

# make menuconfig

Enable the option:

Driver settings --> [*] Enable MMC Support

Save and exit then, to generate the fimage, type:

# ./configure
...
# make

Flash the FOX Board with the new image (see How to reflash a FOX Board) and login to it with root and pass.

Mounting the MMC card

Insert the MMC/SD card inside the holder then mount it typing:

# mount /dev/mmc0 /mnt/0 -t vfat -o noatime,sync

Now you could see the content of the MMC/SD card on /mnt/0 directory typing:

# ls -l /mnt/0
