Bringing OpenWRT to TL-WA801ND v2 (Part 2, Building OpenWRT)


After getting some details about the board it was time to create a build environment. In my case this was just about copying one of the VMs I have prepared just for this purpose. The build environment requires a Linux machine whereas it doesn’t really matter which flavour it is. After everything is set on the VM the very first step is to create a user under which the build will be performed. I created a user ‘openwrt‘ for this and switched user to it. As user openwrt the following commands needed to be executed:

git clone git://git.openwrt.org/12.09/openwrt.git
cd openwrt
./scripts/feeds update
make menuconfig
make

I.e. getting the source, changing into the source directory and updating the feeds (the add-on packages). The ‘make menuconfig’ might not be necessary because everything is already set up for the AR71xx platform. If not configure appropriately. More details about the build system can be found on the developer site of OpenWRT.

The first build ran smooth without any errors or warnings in my case.

I’ve gone through several iterations and even failed attempts to create a working image for the TL-WA801ND after that but ended up with a working source. The patches that were needed and which can be applied to the 12.09 tree are as follows:

(Note: If you want to compile OpenWRT yourself and create a patch file from the above you have to keep in mind that copy-paste of the above will convert all tabs into spaces. This lets the patch process fail for some files and requires manual corrections in order to succeed. To ease this I uploaded the complete patch here.)

After building the image you can find the result under the ‘bin/ar71xx’ directory which will contain the images for all supported devices using that architecture. In order to install the image onto the device you could simply update the firmware via the web interface. The stock firmware will recognize it as valid and allow installation. But for completeness I would like to explain how it can be installed via the bootloader as well. This could be very helpful especially if you’re experimenting with OpenWRT and something went wrong which bricks your device.

The bootloader is able to receive data via TFTP which in turn requires that you have a TFTP server installed. So either you install that directly on your development machine or any other machine you have at hand. You place the firmware image in the data directory of the TFTP server and start it.

Once you power on the TL-WA801ND you will see a message “Autobooting in 1 seconds” in the console. I.e. you have to be quick to abort autobooting by entering ‘tpl‘ into the console. If you succeed the boot process is interrupted and you will be at the bootloader prompt.

You then need to adjust the boot environment by setting an IP address according to your LAN setup, the IP address of your TFTP server and the name of the image you’re about to install.

Issuing the command ‘tftpboot‘ will start the download of the image.

If the download was successfully done you will get the amount of transferred bytes (0x3c0000 in the above example) which is then used for the next commands which first erases 0x3c0000 bytes in the flash starting at 0x9f020000 and then copying that amount of data from the RAM starting at 0x81000000 into the flash starting at 0x9f020000. After that was successfully done the bootloader is instructed to start what we flashed by the ‘bootm‘ command:

wasp> bootm 0x9f020000

Here we go! The TL-WA801ND is now running OpenWRT.

[Update: 10.6.2013]

The above patch was missing a file. This is corrected now.

[Update: 5.7.2013]

A compiled binary can be downloaded here.

[Update: 16.7.2013]

A new compiled binary can be downloaded here. It comes with some more preloaded applications:

  • luci
  • luci-ssl
  • luci-app-qos (Quality of Service)
  • luci-app-wol (Wake-on-LAN)
  • snmpd

[Update: 25.8.2013]

I added a note about the patch above.

  1. hello is there a way to use canal 13 ? because it s limited to 11, doesn’t mater wish country i select (i use the client mode)
    i have the same probleme with the wa701nd
    i olso notice the wifi is very poor compared to the 701nd

    1. I experienced the same. There’re two issues as far as I can see: luci is not offering channel 13 and setting the channel via uci is possible but has no effect. I observed similar behavior on other TP-Link devices although I’m not sure if this is specific to the used chips or by design.

      1. The EEPROM in the TP-Link boxes declares regdomain as US no matter where they’re sold. You will have to set ATH_USER_REGD if you want to override this in software.

        Ensure you know the regulations in your country, setting a wrong country/channel/power limit may get you into legal trouble…

      2. Agree. But if you’re allowed to set it to another regulatory domain you’ll see in the log of the access point that it sets to that domain. Nevertheless it does not set any channel above 11.

  2. Maybe I wasn’t clear enough…

    You have to *recompile* OpenWRT with CONFIG_ATH_USER_REGD set to y

    The OpenWRT binaries that you can download from openwrt.org will *not* allow you to select channels 11/12 from the web ui or even via shell in /etc/config/wireless.

  3. You are welcome.

    BTW, nicoo and I did a similar port, for the TL-WA7210N, which goes for ~50EUR.

    https://github.com/ffgraz/openwrt/tree/tl-wa7210n-support

    What’s missing is identification of all the GPIOs (LEDs are easy…) and once that’s done, sending a pull request to the OpenWRT devs. If you have any hints regarding the purpose of the GPIOs on the 801ND, I suggest you create an entry in the OpenWRT wiki. Our WIP wiki page is here:

  4. Good morning ….

    For those people who has a crippled uboot without tftp transfert working i have build a spezial Python Script to upload the new kernel image automated via bootloader console.

    That means unbricking the device with diabled tftp Client in bootloader without desoldering and external flashing IS POSSIBLE.

    I hope some poeple enjoy this way to unbrick the dead device.

    Here is the code:

    THANK YOU

    1. Hi Chri,
      i hope I can help you, but I need some more informations before.

      1.
      Is your device still booting after powering or do you have a reboot loop? Without any connection you can see it at the 4 green led´s at the top of the device.

      Boot loop in bootloader cycle = flashing all green led´s at the same time every 1-3 seconds.

      Booting = different led blinking after powering without flashing of all led´s in a loop.

      The better way is to connect the UART (RS232) of your device to the UART of your PC (Remember the different Voltage of the Ports. You need a Levelshifter to connect both. Without it your device UART Port will be dead for every time.

      2. After connecting your device to PC take a Log of the Bootloader Output and have a look witch bootloader version is installed.

      3. If you have a bootloader with a working TFTP Client you can use the steps posted in the top of this thread.

      4. If you have a bootloader without working TFTP Client you can use my Python Script for unbricking your device.

      4a. On that: Connect your device to the uart of your PC. Look at your PC and write down the Device name of your uart (RS232) …like ttys0 or ttyusb0…

      4b. Copy my script from dropbox in any path of your PC. Copy the new openwrt image to the same directory as the script and rename it to “openwrt.bin”.

      4c. Open the script with a editor end replace the “ttyUSB0” with the name of your UART Port of your PC you written down and save thescript.

      4d. Switch off your Device.

      4e. Open a shell console and change to the path of the script. Start the script with “python tpflash.py” Command (better with Super User rights lige sudo su).

      4f. Switch on your device and wait …… On that take some coffee because the script needs up to 02:10:00 houres to transfert the image to RAM of your device.

      4g. …….. The rest comes up automaticaly …..

      Good Luck

      Regards
      Christian

      2. sorry Christian for my last post…
        I’m an idiot ! It was a good version of openwrt, i’ve just made a mess with network config file…
        It is 12 09 modified version which i’m sure it works.
        Could U give me a link with new version of openwrt which is good for TL-WA801ND v2 ?

        thank and sorry again… do not accept my last post…
        regards
        Cris

      3. It works great with your precompiled image !!!
        Thanks !
        Is your images working with sysupgrade process (via web interface) for device already “openwrt” but with a previous version ? How can we do in a such case without a serial connection ?

    2. Yeah sysupgrade works great too !!! Amazing !!
      Last request (i promess…) : is your image working for 701ND or 901ND ?
      thanks

    I am using your scripts but stop at this step

    — Stopping Bootloader for getting to Console …

    the device is so

    1.
    Is still booting your device after powering or do you have to reboot loop? Without any connection you can see it at the 4 green LED’s at the top of the device.

    1. Good morning Satan,

      it seems you have a connection problem to your device. The script is at Line “data = serialrd(“Autobooting in 1 seconds”); # waiting up the right moment to send STOP to bootloader” now. That means that the script is waiting for “Autobooting in 1 seconds” output from the device….but in your case there are no characters incomming.

      At this point you have to see all the booting output from your device like:

      When there are no incomming characters, please check your UART Connection to PC. There must something be wrong with the wirering.

      Best way is to check the connection before without my script. Therefore please open putty with a serial connection on your port with 115200 speed and reset your device. After that you have to see an output like the text above.

      If there is nothing your connection to device is buggy!!!

        Please verify scripts when reading the file openwrt.bin is taking a more character “L” in the String part

        Offset: 0x81000000L Arraycount: 0 Byteblock: 0x0 Block: 01000000

        The size of the * .bin is 0x81000000

        I think the right thing to be without the “L”

        Offset: 0x81000000 Arraycount: 0 Byteblock: 0x0 Block: 01000000

        when this ending run this command

        erase 0x9f020000L + 0x3c0000
        0x81000000L cp.b 0x9f020000L 0x3c0000
        bootm 0x9f020000L

        right when I think should be without the “L”

        erase 0x9f020000 + 0x3c0000

    1. Hi Satan,

      You are right… Sorry for that. It seems there is a little bug in the script. I will fix it next Monday after my holiday.

      In that time you can input the erase and flashing commands by hand. So i thing transfering the image to ram is working fine.

      As a quick hack you can start the script, transfering the bin to ram. After that ignore the errors on automatic commands and type the erase, flash and reboot command by hand on a console without resetting the device.

      I will fix it soon as possible…

      Regards Christian

      1. Hello Christian

        Thanks for your time and help

        I did as indicated by the manual command, but when I run bootm 9f020000

        starts loading but stops at this step

        [1.080000] VFS: Can not open root device “(null)” or unknown-block (0,0)
        [1.090000] Please append a correct “root =” boot option; here are the available partitions:
        [1.100000] Kernel panic – not syncing: VFS: Unable to mount root fs on unknown-block (0,0)

  8. Hi Satan,

    i have tested my script with 2 devices 5 times. At all times flashing the two devices are done without any error. That means the is now bug in my script. It works fine. But i think it may be poosible that we have some differences in our linux systems. Let me explain my thoughts.

    In one of your post you had a log line like this:

    Offset: 0x81000000L Arraycount: 0 Byteblock: 0x0 Block: 01000000

    This line was printed in my script at line 47 an 68. On my system the output is fine (without the L at the end of the offset adress. Why is it so? Different perl version? it is a standart print syntax in the perl script in the following line:

    print “Offset:”, hex(offset+x), “Arraycount:”, count, “Byteblock:”, hex(x), “Block:”, hexstr;

    In an other post you send a log like this:

    — Found String: wasp>
    erase 0x9f020000L +0x3c0000

    The first line is a log print in line 155. The second line is the answer from the device (it echos the character send to it on the uart). As we see there is some more the L after the string. I think that means the L was send to the device before and it was echoed back. But why is that so? In my perl version and system it works fine without that L.

    So it is possible, that there are some more extra L’s where send in updating the RAM with the hex data.

    So next step is to check your perl and system version. The have to be something buggy with the print command in your version.

    My Perl version is:
    This is perl 5, version 18, subversion 2 (v5.18.2) built for x86_64-linux-gnu-thread-multi
    (with 41 registered patches, see perl -V for more detail).

      Please tell me which * .bin is running the scripts

      Thanks for the help

      1. Hello Christian

        already solved, I could run the scripts and functions well, since I have the device running

        Many Thanks …..

  9. Note: If you get the message “Please choose a file to upgrade!” when attempting an upgrade from the stock firmware via the admin center/web GUI, just rename the binary file to something short and simple (e.g. openwrt.bin).

    The web GUI does not like long file names or file names with special characters.

  10. Hi Satan,

    It makes me happy hearing you solved all the Problems with the script an your device. In the next 14 Day i will develop a new version of the script in c and compile it to a standart linux object file with some new debugging and monitoring functions. I hope working with that is then some more easyer.

    I wish you and your family some lovely chrismas days and a wonderful new 2015.

  11. Hi – Could you upload the latest version of the patch you are using to the DropBox folder. I am trying to patch against 14.07 (Barrier Breaker) but the 12.09 patch isn’t working (understandably!).

    I’m worried if I try to update the patch myself I might miss something, so thought it would be better to see what you’re using.

    Thanks for all your hard work! :)

    1. This is no more required for 14.07. The patch was integrated into the source tree. Version 14.07 supports the device. Just select it in the configuration menu.

  12. Can you share the full .config file you used to build Barrier Breaker image please?
    I want to build from source and it is my first time, I’d like not to mess up having to use serial console afterwards.

  13. Hi

    I just bought an 801ND V2.1 and flashed it with

    openwrt-ar71xx-generic-tl-wa801nd-v2-squashfs-factory

    from the openwrt website.

    It starts up, the four LEDs flash, then the wheel light flashes, and then it stops on, i.e. the power LED and the wheel LED. It doesn’t go any further.

    Can anyone tell me what I’m doing wrong and how to fix this or at least get it back to stock firmware?

    Thanks

    Rob

    1. Hi Rob, why do you think it’s not normal?
      On OpenWRT you sometimes might need additional configuration to associate those LEDs with network activity. The version uploaded here already has those tweaks.
      Try connecting to the AP, it probably works fine.

  14. Hi
    Newbie here and just got hold of an 801ND V2.1 and flashed it with
    openwrt-ar71xx-generic-tl-wa801nd-v2-squashfs-factory
    from the openwrt website.

    It works really well, I need to set it as Bridge with AP, can someone guide me on the configuration please.

    Thanks

  15. This is awesome, I flashed my rooter with your last build r44952, it works flawlessly.

    By the way, I had a “Please choose a file to upgrade!” alert when trying to flash the *.bin, becuse the filename was too long (I renamed it “openwrt.bin”).

  16. any idea how to hard reset?

    i changed the LAN interface (stupidly) to PPPOE and now i cant access the openwrt menu at all :(
    it also cant be pinged.

    when i tried openwrt generic Fail-safe mode, it do give the “quick blink” on gear LED but i cant telnet to 192.168.1.1

    thank you.

  17. TasksOfOhm – Really sorry to bother you good sir. I was having wifi related issues on the latter revision uploaded to your dropbox for my WA801ND v2; drop outs/instability. So I attempted to try what I thought would be a more recently ‘compiled’ image over at: https://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/ “openwrt-ar71xx-generic-tl-wa801nd-v2-squashfs-sysupgrade.bin”

    Not really sure where I stand at the moment, but I am unable to reach ACP at 192.168.1.1. Oddly I can ping, and do receive a response from 192.168.1.1.

    Power LED {Solid lit}, Config LED {Solid lit}, Ethernet LED {Flashing on normal activity – In/Out Packets}

    What do I need in order to revive said device? Can this be done via software, or do I need a UART cable, or other? If additional equipment required, i.e. cables and the like, could you kindly point me in the right direction to what is needed.

    Best Regards,

    stickman89

    1. Hmmm I can still telnet the router, and I believe I can still access it via TFTP… Does this make my life easier? Or do I still need a UART and/or desolder flash chip and reflash that way? If not, what commands can I issue.

      1. No worries… Fixed it myself. Updated root password via telnet. Issued a ‘SCP’ file transfer of the firmware (openwrt.bin) to the /tmp/ directory. Finally, re-installed firmware via sysupgrade -v /tmp/openwrt.bin. Voila.

  18. Muchas gracias por la version. funciona de maravillas, solo una pequeña pregunta, como podria agregar vlans y batman para construir un red en mesh con 2 vlans en bridge, en LuCi no esta la solapa NETWORK — SWITCH, por opkg es imposible no hay suficiente espacio. Saludos

    Thank you very much for the version. works wonders, only one small question, how could add vlans and batman to build a mesh network bridge 2 vlans on in the NETWORK LuCi not flap – SWITCH, by opkg it is impossible not enough space. regards

  19. I have a problem it does boot with your precompiled image but it forces on an ip that is not in the same subnet as my router zo i cant use your script nor connect to the web interface of openwrt now what can i do to fix it in dont have an 3.3v step shifter for a rs232 cable

  20. Thank you very much for porting this software to the TP-Links. I got a bunch of these cheap things and needed a way to expand their functionality and this is the perfect way.

  21. Hi, just wondering, is it possible to convert this AP into a router? a friend a mine bought it thinking it was a router (besides it was less expensive and he thought that it may be a special sale).

    Now he´s stuck with a cable modem and unable to share internet with more than one device. I was wondering that, if it was possible to change the firmware so that the ethernet port would be the wan, and wifi would act like a lan port.

    1. Should be possible.
      You may want to look into NAT and masquerading IPs that come from the wlan interface.

  22. Hi,
    i just updated my Accesspoint with openwrt-ar71xx-generic-tl-wa801nd-v2-squashfs-factory 14.07 unlocked u-boot (r46516) (1).bin

    DHCP after the flash still works. When i type 192.168.1.1 in my webbrowser to reach the webgui i get “Not found The requested URL /cgi-bin/dispatcher.cgi?cmd=0 was not found on this server.

  23. Hello. I flash correctly openwrt with your bin. But I want flash original bin from tp-link and LUCI says “the upload image file does not contain a supported format. Make sure that you choose the genérico image format for your platform”. How I can flash it? The bin is the correct for my tp-wa801 v2. Thanks

      1. ohh, thank you, i don’t see it before. But I try fix it with other method and brick the router with a bootloop. Now i’m use your script for fix it. Thank you very much

  24. Works like a charm! KUDOS!
    I came from a dd-wrt firmware to this one. Had to take the tftp route to get it to flash. It came natural as a “soft” bricked the device trying to flash it (from dd-wrt) with “mtd -r write firmware.bin linux”. Got an error the linux was not supported and locked (or something like that). Then blinkedy, blinkedy, blinkedy :-) brick!
    Made a tftp-server ready and pushed the reset button for a second or so. It came in, grabbed your firmware, and booted up nicely into OpenWrt.
    Thanks again for making this available.
    I’ve made a simple script to push out configuration to multiple units. Windows-CMD which uses blink and sends uci-commands. Installing >10 pcs of this hardware with your firmware next week and needed a way to configure and be able to make changes to them all at once.

  25. What kind of wireless speeds do you guys see with wa801nd/openwrt? It seems that I’m stuck at 20 mbit per second (downstream). Tried different channels, clients, tuning options and so on and so forth, but nothing seems to change the cap.

    Here are my wireless settings:

    wireless.radio0=wifi-device
    wireless.radio0.type=’mac80211′
    wireless.radio0.path=’platform/ar934x_wmac’
    wireless.radio0.country=’DE’
    wireless.radio0.noscan=’1′
    wireless.radio0.hwmode=’11g’
    wireless.radio0.htmode=’HT20′
    wireless.radio0.channel=’4′
    wireless.radio0.bursting=’1′
    wireless.radio0.ff=’1′
    wireless.radio0.compression=’1′
    wireless.radio0.txpower=’19’
    wireless.@wifi-iface[0]=wifi-iface
    wireless.@wifi-iface[0].device=’radio0′
    wireless.@wifi-iface[0].mode=’ap’

    On another note: great work bringing openwrt to this device! Thank you very much!

  26. Hi, can i just upgrade my wa801nd-v2.1 with your latest image (factory 14.07 unlocked u-boot r48549) through stock firmware interface? Or is the tftp flash still mandatory?

  27. Could you please compile an updated (Chaos Calmer/15.05.1) image including your modifications (preloaded luci, luci-ssl, luci-app-qos, luci-app-wol, snmpd)? Or at least tell how you built it (as detailed as this blog post? https://www.andrewklau.com/generating-my-own-openwrt-custom-firmware/)?
    I upgraded from your r44952 14.07 binary image to bleeding edge r49971 Designated Driver and there is not enough space to install luci (opkg install luci) unfortunately, but I can confirm that OpenWRT still works on it.

  28. Thanks a lot man. I bought wa801nd to use it as client to wired router which use internet from iPhone 5. It refuses to work stable because both router and iPhone have quite stupid software. After applying 12.09 bin on router everything works perfect. I am surprised manufacturer did not put any effort to even use your solution. Thanks again man
