This is the coolest router ever.


Installing the SD card driver

opkg update
opkg install kmod-mmc-over-gpio

Mounting to External Media

With Kamkazie 8.09, this is not as documented.

We have to replace init with our custom script:

For 2.4 (This really does work!)

. /etc/functions.sh
mount proc /proc -t
insmod diag
echo 0xb8 > /proc/diag/gpiomask
insmod mmc
insmod ext2
mount -o rw /dev/mmc/disc0/disc /mnt
       [ -x /mnt/sbin/init ] && {    
               . /bin/firstboot 
               pivot /mnt /mnt       
exec /bin/busybox init

For 2.6 (Doesn't Work)

. /etc/functions.sh
        mount proc /proc -t proc 
        mount sysfs /sys  -t sysfs 
        insmod diag
        echo 0x9c > /proc/diag/gpiomask
        mkdir /config
        mount configfs -t configfs /config

        insmod crc-itu-t
        insmod spi_bitbang
        insmod spi_gpio
        insmod gpiommc
        local dir="/config/gpiommc/default"
        mkdir -p $dir
        echo 2 > $dir/gpio_data_in
        echo 4 > $dir/gpio_data_out
        echo 3 > $dir/gpio_clock
        echo 7 > $dir/gpio_chipselect
        echo 0 > $dir/spi_mode
        echo 1 > $dir/register

        insmod crc7
        insmod mmc_core
        insmod mmc_block
        insmod mmc_spi

        mount -o rw /dev/mmcblk0p1 /mnt
        mkdir /mnt/config
        mount -o bind /config /mnt/config
#       [ -x $target/sbin/init ] && {
#               . /bin/firstboot
#               pivot $target $target
#       }
exec /bin/busybox init

We have to format the thing:

opkg install e2fsprogs kmod-fs-ext2
mkfs.ext2 /dev/mmc/disc0/disc # See above for the correct partition path
mount -t ext2 /dev/mmc/disc0/disc /mnt/

Now we are going to copy over the root stuff

mkdir -p /tmp/root
mount -o bind /rom /tmp/root
cp /tmp/root/* /mnt -a
umount /tmp/root
umount /mnt

Note: This will not take over any post configuration of your router. It will be stock after this next reboot.
