* You might have to change the magic number at the end of the OpenWrt firmware to the one used by the stock DIR-615 firmware to get it to upload.

• Frys FR-300RTR is the same as E1 Forum
• April 2016 - Version E1-E4 of this router, wifi is no longer supported with Chaos Calmer release This is due to limited flash storage. See here for more info. That forum article has some tips to get it working with Chaos Chalmer, otherwise you are better off staying with Barrier Breaker release on this platform.
  

*Hardware and software modifications required

• DIR-615 K1 External Link
• DIR-615 I1 External Link
• Others External Link

Installation is fairly straight forward for this router, you will need to access the D-Link recovery console with the steps below.

1. As per the note at http://www.dd-wrt.com/wiki/index.php/DIR-615C , "If your dlink 615 C1 is at f/w 3.12 or 3.11 you may have to revert it to 3.10". The older firmware is available from D-Link support.
2. Set a static IP on your PC to '192.168.0.2'. Some users recommended to use `192.168.0.10` instead.
3. Press and hold the reset button until the power LED starts blinking orange (usually takes ~45 seconds) to switch to firmware recovery mode. Or, hold down the reset button while powering on the router, this is much quicker and only takes 5-15 seconds.
4. Go to 'http://192.168.0.1' from your PC web browser. (Note: most modern browsers don't work, see below for the details)
5. "Browse" and select the OpenWrt firmware (e.g. openwrt-ar71xx-dir-615-c1-squashfs-factory.bin).
6. Let router flash the image, don't worry if it reboots before it reaches 100%. If the page loads forever or times out, your browser or network stack is unsupported - see below for the details.
7. Obtain new IP from the router via DHCP and follow firstlogin.

The firmware update system doesn't support the HTTP header Expect: 100-continue, which is used in POST requests by most modern browsers. If the browser sends this header, it will wait for the server to send a provisional response with status 100 Continue before sending the file contents. This feature was added in HTTP/1.1 to allow servers to reject uploads without needing to upload the file first. The router's built-in HTTP server claims to support HTTP/1.1, but it never sends the 100 Continue response so the browser waits forever or eventually times out.

Internet Explorer 6,7,8 on Windows, Firefox 13 Portable Edition on Windows 7, Google Chrome 49 on Windows 7 are known to work.

On GNU/Linux, Firefox 13.0.1 has happened to work. Problems have been reported with newer versions and most other browsers.

There seems to be some compatibility issues with the firmware update system network stack and at least Linux 3.5.3 and curl 7.27.0. Even forcing curl down to HTTP/1.0 resulted in a hang. One known working configuration is NetBSD 5.1.2 with curl 7.26.0. Downgrading curl to 7.26 on fresh version of GNU/Linux doesn't solve the issue.

Alternatively, to upload an image you might try to use the curl command-line HTTP client like so:

curl -0vF files=@openwrt-ar71xx-dir-615-c1-squashfs-factory.bin http://192.168.0.1/cgi/index

Same actions(C1 and C2 have same hardware and openwrt image), but to upload openwrt image in recovery mode, you must to edit C1 openwrt image by hex editor.
Just add 30 31 before lastest not zero values:

D1, D2 and D4 works now fully out of box.

Wireless Repeater function dos not work! however Client mode works fine. (Maybe attached another router on the LAN ports for WiFi woth another subnet????)

Installaion/Flashing Guide for D2 (Chaos Calmer 15.05.1) may work on D1-D4

1. Download factory.bin for DIR-615 D.
2. Unplug the unit and configure your network card IPv4 to IP 192.168.0.5, Subnet 255.255.255.0, Gateway 192.168.0.1
3. Power off the unit, hold RESET and power on the device untill you see a Orange LED flashing
4. Go to http://192.168.0.1 and upload the firmware. If the upload does not start, just try another browser, e.g. Firefox.
5. Perform initial configuration (Turn on Wireless, Set a Router Passwod also dont forget any port forwarding needed etc) (First login). (http://192.168.1.1)
6. Restart the Device, Yes again
7. Connect the WAN cable to your Cable Modem or Switch

Works with the latest Chaos Calmer 15.05.1 (2015) build.

1. Download https://downloads.openwrt.org/chaos_calmer/15.05.1/ramips/rt305x/openwrt-15.05.1-ramips-rt305x-dir-615-d-squashfs-factory.bin.
2. Open Emergency Room.
3. Upload the firmware. If the upload does not start, just try another browser, e.g. Firefox.
4. Perform initial configuration (First login).
5. There could be a problem, that the WAN connection is not automatically configured because the 'wan' interface is not enabled during boot. To fix it:
   • Variant 1: login via telnet/ssh and type 'ifup wan'; edit /etc/rc.local and add 'ifup wan' there to automatically enable it during boot.
   • Variant 2: go to luci → System → Startup → 'Local startup' and add line 'ifup wan' before 'exit 0' line in rc.local. Reboot router.
6. There could be serious problems (reconnects, very high packet loss rate) with Intel Wi-Fi Link 1000 BGN Cards on Windows (the factory firmware from D-Link works just well with these cards). To fix it with OpenWrt, download and install latest drivers from Intel web site. Then go to Network and Sharing Center, open properties of your wireless adapter, then Configure, then Advanced and disable 802.11n mode there.
7. By default the WAN LED is not configured correctly. To fix it: Go to System → LED Configuration and change the first LED config as follows:
   • Name: Status LED (green)
   • LED Name: d-link:green:wan
   • Default state: unchecked
   • Trigger: netdev
   • Device: eth0.2 (you can find this on Network → Interfaces under WAN)
   • Trigger Mode: All checked (Link On, Transmit, Receive)
8. There could be a regular connection resets. The problem is described here: Ticket, Forum, SuperUser

D4

: D4 build instructions

Updated D4 install instructions (AArc2) are here: https://forum.openwrt.org/viewtopic.php?id=35184

: The DIR-825 has a better description: installation.

As of R36213 this router no longer needs a custom build. The following only applies to older revisions.

Requires at minimum a customized /etc/config/network. If you have a working network with DHCP server you can put the following in your /etc/config/network (you have to edit via serial connection for the first time or have a custom build with the modified /etc/config/network):

config interface 'loopback'
        option ifname   'lo'
        option proto    'static'
        option ipaddr   '127.0.0.1'
        option netmask  '255.0.0.0'

config interface 'lan'
        option ifname   'eth0'
	option hostname 'DIR-615_H1'
        option proto    'dhcp' 

Now you should be able to telnet to DIR-615_H1

This documentation refers to current trunk of 03.04.2013. Instead of using the above procedure, you can build the image following the next steps. It will create a working image with dhcp on wan and fixed ip 192.168.0.1 on lan.

- Download current trunk. I've downloaded it from git mirror:

git clone git://nbd.name/openwrt.git

Revisions D1 to D4, H1 as well as I1 are pretty much unbrickable as they have a built-in firmware recovery mode. Revision D5 does not have built in recovery.

To access, simply hold down the reset button while powering on the router. The power LED should blink orange. Set your computer with a static IP in the 192.168.0.x range, and open 192.168.0.1 in a web browser. Recovery mode loads up within a few seconds, but doesn't respond to pings. If the power LED is blinking orange the above page should be accessible.

You will need to flash either a stock firmware image or Openwrt-factory image, *not* a sysupgrade image.

Since this part is identical for all devices, see Basic configuration.

→wireless.overview This router requires the packages kmod-ath9k and wpad-mini.

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

• To remove the cover simply remove the 2 back rubber feet.
• There are two screws holding the PCB to the bottom cover.
• On each side successively, from the top, insert flat screwdriver about 1/3 of width from the back and pry gently. The back of the lid will goes up. When both sides of the back of the cover a bit lifted, pull cover towards the back to free front clips.

Looks like C1/C2 JTAG lines connected to testpoints tp5-tp8. Pinout is unknown.

Adding JTAG to C1 not easy as some other revisions but should be possible:

• JTAG TDI on R59 top side populated
• JTAG TMS on R60 (bottom side) unpopulated
• JTAG TCK on R61 (top side) populated
• JTAG TDO on R62 top side populated
• JTAG TRST_L on R6/R10
• EJTAG_SEL on R11, R13 (R11 in place 0-ohm to 3.3V so enhanced JTAG selected by default)

E1/E2/E3/E4 has standard MIPS EJTAG JTAG 14-pin header pinout (pic is from E4)

I1 has same footprint and apparently pinout as E1-E4 but still not fully verified.

See port.jtag for more JTAG details.

1. as a beginner, you really should inform yourself about soldering in general and then even obtain some experience!

All C1/C2, E1-E4 and I1 share the same empty footprints and hole in plastic case (except for sticker) for adding cleanly USB support.

22-ohm resistors are for impedance matching of the characteristic impedance of the transmission line in the case of high-speed USB for signal integrity at 480Mbps. The single-ended impedance of the line is in theory 45 ohms but the transceiver has an output impedance too that is added to the 22-ohm resistor. For full-speed (12Mbps) or low-speed (1.5Mbps) communication, these resistors are not mandatory. For reasons like not having the required 0603 22-ohm surface mount resistors or skill required to solder them and if you plan on using only full-speed and low-speed USB devices, you might decide to replace these resistors with pieces of wire-wrap wire, which are easier to solder than 0603 resistors.

For high-speed, full-speed and low-speed USB, a host has to provide 15k pull-down resistors on D+ and D- lines. E1-E4 and I1 revisions have 0603 footprints for these pull-down resistors. C1/C2 revisions do not have footprints for these pull-down resistors. If you do not have 0603 resistors, the skill required to solder them or not the footprints for soldering, you may want instead use through-hole resistors soldered on the bottom side of the USB receptacle footprint.

Since the DIR-615 uses a +5 V power supply (from 1 A to 2.5 A according to the revision), one can use it as is to power the USB device. Although this is not good practice. USB hosts have normally some protection from excessive current drawn by the device. This protection shuts down the VBUS supply when a given current threshold is reached.

Revision C1

U4 fooprint is for a dual USB high-side power switch partnumber G526-1 or G526-2 by Global Mixed-mode Technology Inc. Datasheet links: long one single page. These parts are obsolete. Good luck finding them. A pinout compatible and mostly similar in terms of electrical characteristics is MIC2076A-2YM.

The Device uses a DDR1 16Mbit x 16bit (16Mibit*16=256 mebibit. 256 mebibit/8=32MiByte) 400MHz chip Zentel A3S56D40FTP. Replace it with any 32Mbit x 16bit chip. 333MHz instead of 400MHz also works fine. It's quite hard to find these chips. One of the ways to get them is to have a look at DDR SO-DIMM (because SO-DIMM modules are shipped with x16 chips). Since there are no 64Mbit x 16bit DDR1 Chips available → no 128 MB mod!

The most easy approach is to seek for a 4-chip DDR 256 MB module. These all have x16 chips too. Chips only on one side (not to be confused with double-sided 256 MB modules with 4 chips on each side) and only 4 of them - that's the best chance to get some. They represent a small percent among usual 8-chip modules but this is equalized with the amount and "cheap as dirt" price of such DDR 256 MB modules.

Working chips:

• Hynix HY5DU121622DTP-D43 (From Mustang DDR SO-DIMM 512 MB)
• Hynix HY5DU121622CTP-D43 (From Hynix DDR SO-DIMM PC2700S-25330 512MB DDR 333MHz CL 2.5, chips are 400Mhz compatible due to "D43" marking.)
• Infineon HYB25D512160BE (From Infineon DDR SO-DIMM 512 MB)
• Elpida EDD5116ADTA-6B-E (From Elpida DDR SO-DIMM 512 MB)
• Elpida EDD5116AFTA-5B-E (From Elpida DDR SO-DIMM 512 MB)
• Alliance AS4C32M16D1-5TCN (From DigiKey, $2.76)
• Samsung K4H511638J-LCCC000 (From База электроники, 117 ₽ )

Additional list that may work:

Uboot and Kernel patches for 16MB Flash External Link

Take some GPIOs which are connected to LEDs or switches, 3.3V and GND from the JTAG header and use the mmc-over-gpio kernel module. The kmod-leds-gpio and kmod-input-gpio-keys-polled kernel modules have to be unloaded before. The blue WPS LED will show when the SD-Card is being accessed and the power LEDs will flicker while data is being transfered.

If you forgot your password, broken one of the startup scripts, firewalled yourself or corrupted the JFFS2 partition, you can get back in by using OpenWrt's failsafe mode.

• Unplug the router's power cord.
• Connect the router's LAN1 port directly to your PC.
• Configure your PC with a static IP address between 192.168.1.2 and 192.168.1.254. E. g. 192.168.1.2 (gateway and DNS is not required).
• Plug the power on and wait for the POWER LED to blink green.
• While the POWER LED is blinking press any button (Reset and Secure Easy Setup will work) once.
• If done right the POWER LED will blink faster.
• You should be able to telnet to the router at 192.168.1.1 now (no username and password)

NOTE: The root file system in failsafe mode is the SquashFS partition which is always readonly. To switch to the writable root file system (JFFS2) run mount_root command and make your changes.

1. Forgot/lost your password and need to set a new one: passwd
2. Forgot the router's IP address: uci get network.lan.ipaddr
3. Accidentally run opkg upgrade or filled up the flash by installing
   too big packages or need to clean the JFFS2 partition and start over: mtd -r erase rootfs_data

When you are done with failsafe mode - power cycle the router and let it boot normally.

The D-Link DIR-615 has two buttons. They are WPS and RESET. The WPS button has its own blue led.
The buttons can be used with hotplug events. E. g. wifitoggle.

How to configure LEDs in general, see the LED section in the Wiki.

Rev C: The DIR-615c2 has 1 blue, 3 green and 2 orange controlled LEDs:

Rev H1: The same LED configuration applies to Rev H1.

Revision C2 has 6 free (non-used) GPIO ports. To use them you should do some solder work. Please train you solder skills on broken motherboards before trying to do this on working hardware.

There is also one free GPIO5 used by dir-615c1:green:wancpu led interface. This led interface is useless so we can just desolder r218 (located between q7 transistor and led10), remove led definition from mach-dir-615-c1.c recompile/reflash kernel and use GPIO5 as we want.

To activate GPIO interface you should export it using command 'echo N > /sys/class/gpio/export' (N is a GPIO number). Then you can use /sys/class/gpio/GPION interface to control GPIO (set/get direction, value, etc). Also you can use i2c_gpio_custom/w1_gpio_custom kernel modules for 1wire/i2c protocols over gpio to connect devices/sensors/actuators to your router.
