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.
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 then
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
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
to mount the card type
mount /dev/mmcblk0p1 /mnt
and you have access to the files on your micro sd card now in the /mnt directory
to unmount the card simply type
umount /dev/mmcblk0p1
much thanks to zucchini for the help
