The original source code for the MMC drivers that were released for the LX were not completed but lucky for us there was a patch included that finishes them to a usable state.


Notice: Hot swapping is not supported yet and may lead to data loss in the event that the card is not unmounted before it is removed.

As these drivers haven't been through extensive testing you should backup any important information on the card before use.


Here are the files you will need (Located on Moogle's server for now) mmc_patch_Kconfig.patch mmc_patch_lf1000-sdio.patch

to apply these patches just copy them to /drivers/mmc/host/ and type the following

patch lf1000_mmc.c < mmc_patch_lf1000-sdio.patch
patch Kconfig < mmc_patch_Kconfig.patch

now when you do a make menuconfig build the MMC drivers as modules by typing the following:

make -j Number of cpu cores+1  
sudo make modules_install

and your modules will be in /lib/modules/2.6.31-leapfrog on your system ready for you to copy them over

it is best to copy them to /lib/modules/2.6.31-leapfrog/kernel/drivers/mmc/

when you want to mount a card simply type the following to load the modules

modprobe /lib/modules/2.6.31-leapfrog/kernel/drivers/mmc/host/lf1000_mmc.ko
modprobe /lib/modules/2.6.31-leapfrog/kernel/drivers/mmc/card/mmc_block.ko

you will then see something like the following

mmcblk0: mmc0:0002 00000 3.82 GiB
mmcblk0:
p1

and to mount the card type

mount /dev/mmcblk0p1 /mnt

and you will then have access to the files on your micro sd card in the /mnt directory

to unmount the card simply type

umount /dev/mmcblk0p1

much thanks to zucchini for the help
