[Hack] TL-MR3020 + hack = OpenWRT USB / WiFi / Ethernet Posted by skywodd ⋅ September 22, 2012 ⋅ 15 comments Filed under madeinfr , openwrt Hello everyone! To continue my project "Blyss box DIY" I started using a small router usb / wifi / ethernet. That it will serve as a "link" between an arduino board (and my code BlyssSpoofer / BlyssSniffer) and a web interface (or other, to see). Other members of the forum arduino.cc have also embarked on the adventure, here's a topic of many on the subject: http://arduino.cc/forum/index.php?topic=115889 The biggest problem was finding a wifi router that can handle the situation. That must comply with the following criteria: - Be small, ideally the size of a map arduino UNO - Have a USB port (or default serial port) to connect the arduino board - Be compatible with OpenWRT (Linux distribution for routers) - Have a network interface: wifi, ethernet or both After much research and advice of the forum members arduino two candidates out of the lot: - TL-WR703N the (available only in China) - TL-MR3020 the (available in France but more expensive) Hardware level is almost the same (same Atheros chipset, same RAM, same Flash) with some differences ready (Ethernet shielded vs. unshielded number of leds, ...). For my part I chose to use the TL-MR3020 with OpenWRT (trunk version): http://wiki.openwrt.org/toh/tp-link/tl-mr3020 Why TL-MR3020 and not the Chinese clone the TL-WR703N? - Over GPIO LED = more = more opportunities for hacking - 2.54mm pitch connector series (no = standard not to break the head with son "flying") Against by good price level is not the same thing ... 17 € for the TL-WR703N on ebay against almost double for the TLMR3020 on amazon, LDLC, ... You choose In this first article I will detail only the hardware part. I will discuss the software part in a separate article. The box: If you read my articles for some time now you must have noticed that I love unpacking everything I receive a picture This router is no exception, so here is what the box looks like:
The router inside the box with its protective film:
And all accessories many and varied:
Cable mini usb power, adapter 5v sector, an ethernet cable in short, everything you need for a user "classic".
Router, small tower owner: The router as a whole:
Besides the color (gray instead of blue) and the duo led + button there is no aesthetic difference with the TL-WR703N. At the front:
Include: - Ethernet port - Port usb FOOD ONLY - The switch to select the operating mode of the router (with original firmware) On the right side:
We find the usb port to (usually) to connect a 3G dongle. In my case it will be a hub with a USB key (for rootfs) and a map that will be connected to the Arduino USB port.
On top:
5 LEDs: - Power - 3G - Wifi - Ethernet - WPS And WPS buttons. -> First difference with the TL-WR703N, it has only 2 LED (one of which is not installed by default) and a reset button. Ps: this is an ethernet cable ... I do not really trust his strength ^ ^ "
Hulling operation, or how to open a box can not be opened: Open TL-MR3020 box is just impossible without a knife with a very fine blade (and solid) and lots and lots of patience ...
To open the case you have to jump two clips of colorful covers, while sliding a knife around the cap to break the glue dots. The first clip is just above the port mini usb, the second face-to ~ 1.5cm to the left of TP-LINK logo. This is what it looks once the box open:
You will notice the small squares around the box are ALL stuck Ultrasound top cover. Ps: Be careful not to injure yourself by sliding the knife blade into the slot of the case, an accident can happen so quickly ... The electronic circuit: Once the box is open (finally) possible to see what is hiding in the beast:
The revision number of the circuit is on the ethernet connector:
As you can see I have a version 1 revision 7. -> 2nd difference with the TL-WR703N, TL-WR703N the ethernet port is screened, the TL-MR3020 it is not ... The details of the hardware: I have not really followed any particular order, it is a little loose + Atheros chipset antenna:
The Atheros chipset is the heart of the router, it is composed of CPU and some ethernet / wifi. It is an Atheros chipset AR9330 revision 1 (= AR9331). The cpu is within the range of AR72xx and more precisely a turning AR7240 400MHz. The party supports a maximum of wifi 802.11 b / g / n 150Mbps. Part ethernet when her 10Mpbs modes and supports 100Mbps. Mini usb port and power port usb "classic":
Mini usb port is only there to provide the +5 v circuit. It can not be used or other usb device. According to the wiki the TL-MR3020 OpenWRT can operate with relatively low voltages of about 2.6/2.7v. This leaves the possibility of using 1S 3.7V lipo battery for power (I'll have to test to see). The second USB port, more "classic" can still be used to it by usb host like any normal USB port. Just have the proper drivers in his image OpenWRT and all will be well RAM and LEDs:
RAM is 32MB in size which leaves a lot of room for the user.
When the LEDs are the numbers 5 As I mentioned a little earlier. Detailed wiring leds is available on the OpenWRT wiki: # http://wiki.openwrt.org/toh/tp-link/tl-mr3020 leds SPI flash memory:
SPI is the flash memory of 4 MB in size, it is cut along the plane memory if below: mtd0 mtd1 mtd2 mtd3 mtd4
(128Ko) : u-boot (1Mo) : kernel (2.75Mo) : rootfs (64Ko) : configuration (64Ko) : art (= Atheros Radio Test)
Especially not touch the memory area called "ART" if the wifi chipset will not work any more. If you ever brickez bootloader router it is possible to salvage by unsoldering the flash by connecting a programmer.
The OpenWRT wiki provided even a factory image of the entire flash: http://wiki.openwrt.org/toh/tp-link/tl-mr3020 # restoring.original.firmware (2nd link in "link dump") For safety I'll do a full dump area and mtd0 mtd4 ... But I will discuss in the article on the software Buttons:
There are two buttons, wired three GPIO. The first button is labeled "button" is normally used to activate WPS wifi authentication. The second button is labeled "slide" and has three positions, it is normally used to select the operating mode of the router. Detailed wiring buttons are available on the wiki OpenWrt: http://wiki.openwrt.org/toh/tp-link/tl-mr3020 # buttons The serial port:
This is the most interesting because it is this one that allows access to the bootloader (u-boot) and fundamentally change the linux kernel and rootfs router. I do not use the flash method through the web interface, I find it too wobbly. Method by flash bootloader requires extreme vigilance to avoid bricker router but when we used it is much more reliable. The serial port is wired as follows: | (vcc) (gnd) (rx) [tx] |
() Represents a round pad and [] the square pad (pin 1 mark). The serial port is configured for 115200 baud, 8 data bits, 1 start bit, 1 stop bit, no parity and no flow control. Problem: The serial port is wired a little strange, so that with some serial adapters -> USB that does not work properly. I tested with my sparkfun ftdi basic of, actually it was not working base. But do not panic, just put a resistor between VCC and 10K Tx to solve the problem (Thanks to those who took the time to add a note about it in the OpenWRT wiki, otherwise I would still be looking for the problem ^ ^) History of doing things I did own a serial adapter -> FTDI basic with a piece of pcb that was lying:
Note: I have not connected the VCC pin connector FTDI basic circuit to VCC, so I can use a ftdi basic 5v or 3v3 without problems Once the serial connector soldered it looks like this:
Then simply plug the adapter into the serial connector:
Basic and ftdi on the adapter:
Then you plug the usb power hop and all lights!
And the serial monitor gives a nice serial console:

Default password for serial console: login = root password = 5up Default password for the web interface: login = admin password = admin Ps: I have not taken the time to look at the web interface based ... I just booted the router to make sure it worked and then immediately after I removed Next steps to take: - Compiling OpenWrt trunk for TL-MR3020 - Flash the new firmware - Update u-boot bootloader (though the original seems already up to date) - Boot the uImage and rootfs on a partition of the USB key
- Integration of the card with my arduino code BlyssSpoofer / BlyssSniffer - Implementation of a GUI html + cgi Bonus for the curious: Both sides of the pcb in high resolution
Good weekend and hack at all!

Mmhh .. Project forward. Posted by Alex (@ venedesign) | September 23, 2012, 10 h 48 min Reply to this comment
2. Hello, I'm still your wonderful blog with attention, great job! Questions about the project, why not directly interface with which you Raspbery Pi permettera to have a web interface and interact directly with arduino via usb? Maybe I haven not quite understand the purpose of your interface with the wireless router, but I was able to do that with 2 arduino + Pi and it works pretty well! a+ Posted by tibo | September 24, 2012, 1 h 30 min Reply to this comment

Because it's cheating I prefer to use a 400MHz ARM linux kernel homemade, modified debian iso that I do not really know how. Posted by skywodd | September 24, 2012, 20 h 29 min Reply to this comment
3. Great project! I have the same router and I confess I use RBP to have a web interface and control the Arduino. The advantage is that your project you'll save probalement RBP and therefore if the project is embedded ca will make you save a lot in energy consol! To be continued!

Consolidated level is unbeatable, managing the power supply properly wifi chipset should be able to run the same mounting lipo battery for a long time. Posted by skywodd | September 24, 2012, 20 h 30 min Reply to this comment
4. Superb article, I'm impressed. I just (re) order * this router to use for a tablet more basic, but it makes me want to dig even that for the usb host with open wrt

5. Hello great article For my part, I started a project based on an equivalent basis OpenRD Marvell I use this box in addition to NAS / firewall / router Posted by David | October 18, 2012, 13 h 49 min Reply to this comment
6. Skywood salvation, I find this post particularly interested in, I myself on one MR3020 lequelle I experimente, but only in software. I have installed openwrt version and I must say it makes me learn a lot about the administration of a network under linux, I spend a lot of time on the distribution site and I am determined to know clearly all subtlety this router. I also have a small question to answer if you know because in the configuration files of network interfaces by adding an option "option macadrr 'xx: xx: xx: xx: xx: xx' is supposed to be there and changed the mac address of wifi chipset slab but its not work ... On that after I read it that semblerais to change the mac address should rewrite the mtd4 which contains test and notement radio address in question, precisely, does not recommend you touch ... you need to say I burned with desire finally good if you know a little more I'd love to listen to your good advice before potentielement a big mistake, especially since I have no way to rewrite the flash. And if not when is write what you think the rest of the article?! Posted by karol | December 28, 2012, 23 h 54 min Reply to this comment

On >> after that I read that it semblerais to change the mac address should rewrite the mtd4 which contains test and notement radio address in question, precisely, does not recommend you touch ... If you made a backup of your bootloader mtd4 and is in good health you can try. But without knowing the proper data architecture config is little chance to do something functional (a checksum is surely some pars) ... Usually you can alter the MAC address at the bootloader (uboot), Linux kernel (macchanger) or hardware (by cons ... how I know). Especially >> I have no way to rewrite the flash. If the bootloader is alive you can always reflash a backup TFTP. Or with the tool if the linux mtd boot even after your changes. And if >> when is write what you think the rest of the article?! For now I know I put almost a month to compile custom OpenWRT image because full problem with my linux ... Now compile the kernel I'm trying to compile the latest version of uboot and throw everything on the router.

thank you to respond as quickly is what you have links / books or any other documentation to advise me because you're a response, I realize that I am missing ... you're conaissances really comfortable with the handling of the genre: install a bootloader or use the mtd (this is a command asser obscure for me ...) PS: I is part of a community of computer security http://www.zenk-security.com/ there is more info but I focused mainly animates the category "electronic" forum. I invite you to come pay a visit; D (just to prove through some test to be reached in order to avoid anyone does come, but you ca is gifted and should not ask you to problem) was also on Rizon irc # Zenk-Security Posted by karol | December 29, 2012, 1 h 22 min
Is >> that you have links / books or any other documentation to advise me because you're a response, I realize that I lack knowledge ... Not really, I only look at doc / manuals and "how to" projects that I use. It is in English, but at least it is always up to date and (mostly) is very comprehensive. You're really a >> comfortable with handling like: install a bootloader or use the mtd (this is a command asser obscure for me ...) Really comfortable, not completely freak, yes I compile and flash without me I take the lead, in the worst case I know what I reflash by unsoldering the memory chip so good. At the "instinct as they say ^ ^ >> PS: I is part of a community of computer security http://www.zenk-security.com/ there is more info but I focused mainly animates the category "electronic" forum. I know, this is the forum with a kind of diode as logo ^ ^ I had seen pictures of your team on the website of the ndh (by the way I never have to go to the ndh ... sniff).

7. I was just thinking that you was rather kind to draw the right information to the left for your projects, but sometimes it feel good to pick up a good book / doc reference and be guided by the expert. I should invest in gear type: programateur for microcontroller eeprom or give me a ca autonomy and can be faciliterai things to experiment myself .. I seemed to have read to you that your father was electronics, I guess it helps a little? In fact it is us! I never go either to the NDH .. but may be this year, who knows? I am of course with some members so maybe there is a way I tick. Regards Posted by karol | January 2, 2013, 16 h 56 min

I should >> invest in gear type: eeprom programmer for microcontrollers or give me a ca autonomy and can be faciliterai things to experiment myself .. I'm just a map and a bus pirate programmer Pocket April. Not need special gear well, most of the time I go tinkering that I need a card with arduino, arm or another. By cons by the end of the month I will take a digital oscilloscope (my old cuckoo analog hs), this is really a tool to tinker with hardware requirement. I seemed to have >> read you your father was electronics, I guess it helps a little? Yep, and I get to pick nice stuff at times. Posted by skywodd | January 2, 2013, 17 h 26 min Reply to this comment
