Hi everyone,

Main specs:
CPU: MediaTek MT7620 @ 580MHz
RAM: 64MB DDR2 (Winbond W9751G6KB-25 64471X600ZY2)
Flash: 8MB (MXIC MX 25L640GE)
External WiFi: MediaTek MT7610EN
UART: 57600 8N1

I got a D-Link DAP-1520 for free from my ISP as a sign up bonus. Since I use OpenWrt, and this doesn't (yet) run OpenWrt, I had no use for it, so I ripped it apart.

The device is powered by 5V from an integrated AC->DC power supply. There is a unpopulated 4 pin 2.54mm UART header on the board (upper right from front, upper left from rear), which you can see the SoC console from. I soldered the pins you see in the photos.

I have attached the full boot log below. The device requires at least 2A @ 5V to complete booting and bring the WiFi radios up. If the power source cannot supply that much, it will typically power cycle around the initialization of the 5GHz radio.

The main CPU is below this heat spreader, but it's quite firmly glued to the chip below. I didn't remove it as I was concerned I would damage the SoC in the process of removing it. I have not investigated the test points below the main CPU yet.

Does anyone else have interest in seeing OpenWrt ported to this device?

Why? With only radio connectivity this device can only relay packets. Replacing a bespoke OS with a multi-function OS would serve no purpose (and hinder packet transfer).

Actually no. Since it has some flash, and RAM, you could easily run uhttpd on it to serve some static content if you wanted.

It can also be used as part of a mesh network.

Max Hopper wrote:

Yes, except it's not a bespoke OS, it's regular Linux/busybox. As you can see from the uboot log, it's running 2.6.36.

D-Link aren't exactly known for their high quality, bug free firmwares. I see no reason why, if we can get a recent version of OpenWrt running on the device, it wouldn't also perform as well as it did running the D-Link firmware.

Please provide some actual evidence as to why putting OpenWrt on this device wouldn't make it more useful than the D-Link firmware. Thus far all you've provided is an overly negative opinion.

Where would the static content reside when power is removed?

Yes, a bespoke OS. One where unnecessary components have been removed, e.g., PPPoE, netfilter and ntpd.

The same place where overlayfs resides. How do you think your normal OpenWrt router retains its configuration between reboots?

Yes, all those configuration files in /etc, those are also "static content" which don't magically disappear when the device is rebooted. Last I checked, you don't have to reflash the entire router to change configuration files in /etc...

Max Hopper wrote:

I can run OpenWrt without PPPoE and ntpd if I want. Since netfilter is actually part of the Linux kernel, it exists on the D-Link firmware as well.

By your definition above, OpenWrt qualifies as a "bespoke" OS, since you can choose how minimal you want to make the installation.

Please keep trolling though, this is amusing.

Indeed, OOTB OpenWrt is written to the MTD. In the device under discussion it is 8MB of storage. Building a .bin which includes a reasonably robust webserver, approaches that size. And considering the effort to create .ipks of content, which is arguably not truly static, hardly seems worthwhile, now does it?

Yes, netfilter is integral and simply put, a callback framework. The vendor OS would not require the implementation, iptables, and probably it is not present. Now, a static webserver would also not require an implementation unless it were to procure it's content from a remote source.

That said, the suggestion to deploy the device as a mesh node is worth consideration, which I initially dismissed. It will however require iptables.

EDIT: corrected typo (thanks to tmo26)

What is your point? Most devices running OpenWrt have 8MB of flash. I have a bunch of WT3020 devices deployed running Strongswan IPSec, in 8MB, with about 1MB to spare.

For static content, the standard uhttpd daemon works fine.

Max Hopper wrote:

Actually if you already have the OpenWrt toolchain built, it's quite easy to create an opkg with whatever content you want in it.

Glad to hear we've finally identified a potential use case worthy of your consideration.

How about you just sit back and enjoy the show?

It's quite clear you have nothing useful to contribute here.

Combatting ignorance ... with more ignorance? Interesting concept.

I for one am looking forward to hmartin's exploits. OpenWrt shines when it's run on low-cost, niche hardware, I can think of several use cases even for a severly limited device as this one. Also, even if it's "just" replicating the original firmware's usecase, I'll take OpenWrt over the original firmware any day of the week (and throw in an unsuspicious OpenVPN server in the middle ^_^ ).

Well, I got sucked down the rabbit hole yesterday in investigating this device. I didn't make any progress toward porting OpenWrt to the device because I was dealing with D-Link's terrible GPL source code.

I now know why these devices are typically terrible. What else can you expect when the manufacturer's build instructions begin with "Install Ubuntu 10.04 i386", the build environment is "AthSDK" and the makefiles delete a bunch of Atheros files before creating the flashable firmware image?

I mean, the device doesn't even have Atheros chips in it, unless I'm missing something fundamental about MediaTek's corporate history?

Oh, and ALL the makefiles are hard coded to expect the toolchain to be in /opt/buildroot-gcc342 and the source code in /home/AthSDK. I tried to change them, but in the end I just gave up and created some symlinks to those places.

Since my security-fu is lacking, I wasn't able to use any of the HNAP vulnerabilities to start telnetd. I was, however, able to build the D-Link firmware from GPL sources with a telnet daemon (it isn't compiled into busybox on this device by default, probably for space reasons).

Except, even with telnetd running, I couldn't login to the device. In /etc/shadow there is only one user with a password hash (Admin) and if you Google it, there are a lot of people musing over the unusual length of the hashed password with no results.

The web interface login didn't work either.

Never one to give up hope, I recompiled the D-Link firmware to include nc, which listens on port 8023 and just dumps you to /bin/sh as root. Secure? Absolutely not, but sometimes the quickest way in through the front door is to replace the lock with one you control (insert joke about IoT lock here).

You can't even change the password for root because passwd isn't included in busybox. I guess D-Link never saw the use case for a user to change the root password!

I'm going to continue to try and put OpenWrt on this device, but in the mean time, if anyone else has one and wants to poke around the D-Link OS, you can find my totally insecure, backdoored firmware here: http://watchmysys.com/blog/wp-content/u … 106B04.bin

Note: the backdoor only includes telnetd (port 23) and nc (port 8023). I haven't backdoored the firmware in any other ways.

So, the board runs Barrier Breaker without any modifications. Just download the MT7620A development board image and flash from u-boot. https://downloads.openwrt.org/barrier_b … pgrade.bin

Chaos Calmer and Designated Driver kernel panic on boot due to a bug in pinctrl. The fix described here is enough to get the board to boot DD trunk: https://dev.openwrt.org/ticket/19213

Only 2.4GHz radio is working right now, I'm looking into the drivers to also support 5GHz.

D-Link u-boot is built with dual image support, so we need to replace it with u-boot with single image support.

u-boot: http://watchmysys.com/blog/wp-content/u … ap1520.bin
openwrt DD trunk: http://watchmysys.com/blog/wp-content/u … pgrade.bin

I have no procedure to update the router from the included D-Link firmware. However, you can flash u-boot and the OpenWrt firmware from the u-boot environment by uploading the firmware via serial. Since u-boot is configured for 57600, you'll wait about 15 minutes to upload the above sysupgrade image. Flashing via SPI programmer is much faster, but I realize the number of people who have an SPI flasher is probably a lot less than people with USB<->UART adapters.

Generic u-boot flashing instructions which also apply to this board: https://wiki.openwrt.org/doc/howto/gene … ing.serial

More info to follow soon.

Here's the full boot log of the board running the new u-boot and OpenWrt DD:

You need to get the eeprom from mtd2:

# cd /lib/firmware
# dd if=/dev/mtd2 of=soc_wmac.eeprom bs=512 count=1
# reboot

Then you can enable WiFi using uci:

# uci set wireless.@wifi-device[0].disabled=0; uci commit wireless; wifi

And then join OpenWrt WiFi network and go to 192.168.1.1 to visit luci.

Hi Hmartin,

I read your post with interest and would LOVE to have OpenWRT on the DAP1520. My use case - Wireless NAT gateway with DHCP on the private side for use in hotel rooms. The default code from D-Link is truly a repeater, with all traffic passed L2 transparent from the repeated to the parent LAN segment (and vice versa). I would like the DAP to register its self via DHCP with the hotel room wifi, and then offer private DHCP addresses on the NATed side to my other devices. Usually Hotel wifi will only offer 1 address per login, and that address will be secured from all others on the WIFI subnet (host to host firewalling).
Why? Because now I can take my home WIFI config with me (secured with WPK2-PSK) and get my family on line without having to change ANY other wifi settings (other than me logging in). And when you have 3 kids wife with 2 devices each, managing that stuff becomes a PITA.

So - if you can get this to work - cool :-)

I should have realized this sooner, but there is no support in OpenWrt for the MT7610E.

There's the possibility that it will be supported in the future, but this depends on the success of reverse engineering:
https://dev.openwrt.org/ticket/21483

It seems that someone has the mt7610e kmod source code on GitHub:
https://github.com/i80s/mtk-sources

Another person wrote how to compile the module source code against 3.14.18, but these instructions are from 2014 and are now out of date:
http://www.cnblogs.com/jzyuchen/p/4094752.html

Unless support for MT7610E is added to OpenWrt through another driver, then I don't see any point to support this device. Since only the 2.4GHz radio is working, OpenWrt has less functionality than the D-Link firmware. While it was a fun project to put OpenWrt on the router, without support for 2.4GHz and 5GHz, I don't want to continue.

The discussion might have continued from here.
