Hello, I have a dir-300 B1 identical to this: 
I would like to add a MMC to my device, I found this tutorial: http://tinyhack.com/2010/04/04/d-link-d … nd-sd-mod/
but the hardward is a little bit different: 
.
Someone managed to get it working on a device identical to mine?
Thanks

Anyone had any success with this?
I connected GPIO as follows:
option 'DI_pin' '9' - Green Power LED
option 'DO_pin' '8' - Amber Power LED
option 'CLK_pin' '13' - WPS LED
option 'CS_pin' '0' - WPS Button
I also removed button and led modules from kernel, so I can change state of LEDs and read button status from GPIO control and nothing is using/blocking those GPIO.
When I start /etc/init.d/mmc_over_gpio LEDs blinks for a moment. But some errors shows in dmesg:

input_core 19984 1 input_polldevI tried to change GPIO order but always with this same effect.
I aslo noticed that GPIO levels are 'reversed' - when I set value to 0 LED is on and off when set to 1. This same with button - when pressed is 0 and not pressed 1. Is it OK?
I will be very grateful for your help with this issue.
----------- Added:
Some progress.. I removed LEDs - WPS and Power. Also rearrange connections and change to smaller SD CARD - it is detected now, but I have problems with errors:

DONE!
Changed GPIOs to
Data Input = GPIO9 (Green Power LED)
Data Output = GPIO13 (WPS LED)
Clock = GPIO8 (Amber Power LED)
ChipSel = GPIO0 (WPS Switch)

[ 31.410000] mmcblk0: mmc0:0000 SA01G 956 MiB
[ 31.530000] mmcblk0: p1Everything works fine. I think, that debouncing circuits on GPIO0 and GPIO10 mess a little, but they are OK for CS line. I removed LEDs and don't know how it works with them.

Sorry, but could you show screen where this GPIOs situated on plate? thx
P/s my english is bad(
Sure,
yellow = ChipSel = GPIO0
purple = Data Output = GPIO13 (WPS LED)
green = Data Input = GPIO9 (Green Power LED)
blue = Clock = GPIO8 (Amber Power LED)
(green and blue can be swapped - I don't remember which is which)
yellow and green pair together = power supply 3.3V.
cheers,

THNX!!! Iam try this shem
Ok, i try it, but it didnt work for me. What i do wrong?

you could try to rmmod gpio_keys_polled, although that should not conflict.
also, you could issue something like "echo 13 > /sys/class/gpio/export" (and replace 13 with 0, 8 and 9 respectively) to figure out, which gpio is already in use.
Ok, now i have the same problem as podly had. dmesg: http://bpaste.net/show/zKAq0aKoNjbobeID9cRD/
also also
and
DI 9 (Green Power LED)
DO 13 (WPS LED)
CK 8 (Amber Power LED)
CS 0 (WPS Switch)
Everything works fine. I think, that debouncing circuits on GPIO0 and GPIO10 mess a little, but they are OK for CS line. I removed LEDs and don't know how it works with them.
you would not be able to tell what kind of contact on the board what contact ka sd card compare?
whether to make modifications kakieto firmware to install it
thanks

You should delete this packages from firmware (captured some GPIO pins):
1. kmod-leds-gpio
2. kmod-input-gpio-keys-polled
Can sd card be used like this or only mmc?
Can sd card be used like this or only mmc?
Yes.
SD, MMC pins:
Anyone had any success with this?
I connected GPIO as follows:
option 'DI_pin' '9' - Green Power LED
option 'DO_pin' '8' - Amber Power LED
option 'CLK_pin' '13' - WPS LED
option 'CS_pin' '0' - WPS ButtonI also removed button and led modules from kernel, so I can change state of LEDs and read button status from GPIO control and nothing is using/blocking those GPIO.
When I start /etc/init.d/mmc_over_gpio LEDs blinks for a moment. But some errors shows in dmesg:

I aslo noticed that GPIO levels are 'reversed' - when I set value to 0 LED is on and off when set to 1. This same with button - when pressed is 0 and not pressed 1. Is it OK?
I will be very grateful for your help with this issue.

this is so not working on dlink dir 300 rev B1 with atittude adjustment
Maybe, not enought of the power supply. Card not enabled. Need oscilloscope.
I dont think so.It is connected directly to 3.3V rail.
So, guys! Anyone still working on it?
Few days ago I started trying to make this mod, but without results
Can anybody help me on my way?

the green status led is on,
i don't know what can i disable this led and other what i need. pls need help
Did you follow post #13?
Thanx for reply i use

pls help
Well, maybe it's better to take a step back and check, if the desired GPIOs are free for use. Check each one of them like it is described on this page: http://squidge.sourceforge.net/gpio/
Thanx for Reply MBS, meyby now only u can help me
i use command:
root@OpenWrt:~# echo 0 > /sys/class/gpio/export
and have resoult:
ash: write error: Device or resource busy
I have a good read of this article, can I find help.
Sorry, now I realized, that you still have those modules loaded, which already occupy your GPIOs:
leds_gpio 1552 0
button_hotplug 2656 0
gpio_keys_polled 2064 0
So, if you issue a "rmmod leds_gpio" and "rmmod gpio_keys_polled", you should be able export those GPIOs to userspace, and also get the mmc driver to work.
Only issue remaining is, how to get it to work automatically when starting the router. The packages for LEDs and buttons are already installed on the squashfs-partition, thus read-only and cannot be removed. Any attempt to delete or overwrite some files there will just create a reference on the jffs2-partition, which gets mounted somehow later during boot (when button and LED module might already be loaded). So here are the options I see: You can either build your own image, with LED and button modules disabled, or make sure, that those modules get removed, before the mmc gets started (for example put it into /etc/init.d/mmc_over_gpio, or create your own file in that directory and use a START-value of 89).
