ok I tried  insmod mmc

root@OpenWrt:~# cd /
root@OpenWrt:/# insmod mmc
insmod: Loading module failed: No such file or directory

and the lines from dmesg that refer to the mmc are

mmc_spi: Unknown symbol spi_register_driver

also both the surface mount LEDs under the front button are on - is this normal ?

I couldn't tell you what's wrong there. When I used the 2.6 kernel, that package worked without issues for me.

Actually, I think that package does have a startup script. Try typing "/etc/init.d/mmc start".

in the /etc/init.d  directory there is only mmc_over_gpio file

looking into the file is

root@OpenWrt:/etc/init.d# vi mmc_over_gpio
#!/bin/sh /etc/rc.common
# Copyright (C) 2008 OpenWrt.org
START=90

CONFIGFS_DIR="/config/gpiommc"

# add_device(name, DI_pin, DO_pin, CLK_pin, CS_pin, mode)
add_device() {
        local dir="$CONFIGFS_DIR/$1"

        mkdir $dir
        [ $? -eq 0 ] || return 1
        echo $2 > $dir/gpio_data_in
        [ $? -eq 0 ] || return 1
        echo $3 > $dir/gpio_data_out
        [ $? -eq 0 ] || return 1
        echo $4 > $dir/gpio_clock
        [ $? -eq 0 ] || return 1
        echo $5 > $dir/gpio_chipselect
        [ $? -eq 0 ] || return 1
        echo $6 > $dir/spi_mode
        [ $? -eq 0 ] || return 1
        # XXX We have more config options available. Use defaults for now.

        echo 1 > $dir/register
        [ $? -eq 0 ] || return 1

        return 0
}

# remove_device(name)
remove_device() {
        local dir="$CONFIGFS_DIR/$1"

        rmdir $dir
}

mount_configfs() {
        # FIXME: This should probably be done somewhere else.
        mount | grep configfs
        if [ $? -eq 0 ]; then
                # already mounted
                return 0
        fi

and the /etc/config dir does not contain "/config/gpiommc"

not sure if this sheds any light on what I have or have not done yet

still googling on

I installed via x-wrt GUI the package
gpioctl    1.0-1

with the thought I can toggle to the pins and check with a multimeter what happens ( no CRO ) - will have to google for instructions on how to use gpioctl

root@OpenWrt:/# gpioctl --help
gpioctl dirin|dirout|get|set|clear gpio
root@OpenWrt:/# find -name 'gpioctl*'
./usr/bin/gpioctl

./jffs/usr/bin/gpioctl
./jffs/usr/lib/opkg/info/gpioctl.list
./jffs/usr/lib/opkg/info/gpioctl.control

does this mean I am missing something critical ?  do I need something started  ?

Are you sure you have the kmod-mmc package installed? It sounds like you may only have kmod-mmc-over-gpio installed. I thought it was dependant on kmod-mmc, but check. Type "opkg list" and look for "kmod-mmc". There should be three packages.

I installed using the x-wrt GUI and it shows all 3 installed on the packages page

with opkg search '*mmc*'

this page here gives a nice tutorial - though my following it stopped at wget   mmc.o section as that gave me an error

it is a nice tutorial - http://blog.tcsoft.net/linux/openwrt/sd … gs-v4.html - but for 7.09

As I have OpenWRT running on my router I’ll provide the necessary instructions for it here.
OpenWRT Kamikaze 7.09
First, download the compiled kernel-module (adapted for our gpio2-mod) from here.

Connect to your router by ssh e.g. with putty.

# cd /lib/modules/2.4.34 (where 2.4.34 stands for the kernel version and my be different) # wget http://download.tcsoft.net/mmc.o Now mask the gpio-pins – otherwise the router would lock up when we load the module.

# echo "0x9c" > /proc/diag/gpiomask
# cat /proc/diag/gpiomask
0×009c # insmod mmc

Control if everything went like expected:

# dmesgShould show something like this

[INFO] mmc_hardware_init: initializing GPIOs

[INFO] mmc_card_init: set_blocklen (CMD16) succeeded !otherwhise we should check our soldering again.

That tutorial won't apply to you though. That's for a 2.4 kernel. For 2.6 you only need the packages. You won't need to download anything else.

I didn't work much with the package though. I'd suggest searching the net for help on the kmod-mmc package specifically.

Hi all,

Hope this helps

Good luck ;0)

If you're running kernel v2.4, I highly recommend using the SDHC version earlier in this post.  It's much easier to configure and can handle the 4gb+, as well as, the HC versions.

Per Cybersaga's comments this may not work on the v2.6.

Cyber - do you have any experience testing this on v2.6, or is it just a concern that it was designed for v2.4 and may not work.

Yeah, I tried the SDHC module on 2.6 and it doesn't work. I read up a little bit on linux drivers between the two versions and they're totally different.

I am not making any progress with my mmc and 2.6

all the tutorials and help I can find refer to 2.4

I think I will flash my 54GL with 2.4 and do the learning with 2.4 until I believe 2.6 will work

This might be a dumb question, but is there some way to use the SDHC package and an sd card for the installation of extra packages?

---

I got it.... somewhat, there's probally a better way to do it, but I'll post what I did here anyway in case anyone else is having trouble.

Followed this guide http://wiki.openwrt.org/OpenWrtDocs/Kam … MediaHowTo  except

* Did not create a /etc/config/bootfromexternalmedia file
(I was having issues getting the config file to read in properly...)

* use the following script as /sbin/init
(Replace the options for gpiomask and for the sdhc module as necessary )

#!/bin/sh
. /etc/functions.sh
echo 0x9c >> /proc/diag/gpiomask
insmod sdhcd clk=3 din=2 dout=4 cs=7 major=0 maxsec=32 rahead=2 dbg=1
insmod jbd 
insmod ext3 
sleep 5
mount -o rw /dev/sdcard/part1 /mnt 
[ -x /mnt/sbin/init ] && {
        . /bin/firstboot
        pivot  /mnt /mnt
}

exec /bin/busybox init

One extra thing I had to do to get some packages to install, was to comment out the following line in /etc/opkg.conf

option overlay_root /jffs

seems the availble space is calculated based on /jffs, although it installs to /

Thanks Daedelus. I'll try that when I get home. I've been having a hard time getting that to work.

Hi All,

I followed the instructions exactly as above, but only had to make this change in sdcard.conf "dbg=0" to "dbg=2" to get my Sandisk 8gb SDHC card detected and formatted, every thing works good execpt when I reboot the unit all is lost, it does not detect the SDHC card at boot up, what do I have to do so this will survive a bootup.

Regarding the SDHC module at http://4mul8.ca/openwrt/packages/8.09/

1) By default, the /etc/init.d/sdcard script is not set to run at boot time. To enable sdcard initialization at boot time run:

/etc/init.d/sdcard enable

2) There is a bug in the init script that prevents your configuration settings from being passed to the kernel module if "dbg=0" is set in /etc/sdcard.conf.  To work around this problem and have the module work without debugging enabled (slightly faster) do the following:

a) Replace the following line from file /etc/init.d/sdcard

    [ ${dbg:-0} -gt 0 ] || continue

with the line:

       [ ${arg} == "dbg" ] && [ ${dbg:-0} -eq 0 ] && continue

I will try to find the time to fix this bug and re-package the sdhc module soon.

Thanks will give it a try.

Cool

the bugfixed sdhc module v2.0.2 in now in trunk .. please see
