Linux

I have an inbuilt SD/MMC port on my Asus A6R laptop, and I would love to be able to use it. I have found files in my system for it (I am fairly new to Linux). They are in this directory:

/usr/src/kernels/2.6.11-1.1369_FC4-i686/include/linux/mmc

Optional files from there are:

card.h host.h mmc.h protocol.h

Any help as to where to go from here?

What happens when you plug in an SD/MMC card? A lot of times the device (card in this case) will be automounted. Type 'df' before inserting the card, then insert the card, wait a few seconds and type 'df' again. If the card was automounted, there will be a new line in the output that wasn't there before.

I believe those .h files are for compiling a linux kernel and/or any kernel modules/extensions. You shouldn't have to use those to get your SD/MMC port to work.

It does not automount, there is no extra line, it looks exactly as it did prior to inserting the card.

After inserting the card, do you get anything new in the output of 'dmesg' ?

Try running this before then after inserting the card and look for differences. If there are any then if you post them we can probably help.

I'll have a look and see if I have a FC4 system here and see how things are configured by default.

There are no differences. I am thinking about recompiling my kernel to something more update which includes MM/SD card support. Do you think this would be the best idea?

On my FC5 server, I can see that MMC support is compiled as a module:

Code:

# grep -i mmc /boot/config-`uname -r`
# CONFIG_PCI_GOMMCONFIG is not set
CONFIG_PCI_MMCONFIG=y
# MMC/SD Card support
CONFIG_MMC=m
# CONFIG_MMC_DEBUG is not set
CONFIG_MMC_BLOCK=m
CONFIG_MMC_WBSD=m

Try modprobe-ing mmc_core and mmc_block:

Code:

# modprobe mmc_core
# modprobe mmc_block
# lsmod | grep mmc
mmc_block               8649  0 
mmc_core               24773  1 mmc_block

Insert the MMC card, and see if it mounts.

Cheers,

Still nothing, it does not mount.
