Topic: TP-Link TL-MR3020 Support

The content of this topic has been archived between 16 Jun 2013 and 7 May 2018. Unfortunately there are posts – most likely complete pages – missing.

Thanks

I probably need a router in my car for the entertainment system. It will only have ocassionaly internet access when the phone is in the car dock (via usb tethering) and want to provide an approximate time with the router as NTP server
(my china gps does not have an RTC and looses time after each start (--> gps fix takes long)
but I have WiFi and Windows CE has a built in NTP client)

I thought about using a raspberry PI with openwrt and RTC "shield" but it is a bit oversized and I have a MR3020 here :-)

Is there any information what GPIOs can be used for this (there is limited documentation in the wiki)

R6, R11, R12 could be Gpio0, 14 and 15. This is based purely on a visual comparison with the wr703n. I don't have an MR3020 to verify though.

I may be able to check, as I have both TL-WR703N and TL-MR3020 routers, as well as a stereo x40 binocular, let me some time this WE.

But if you don't care much about the sliding 3G/WISP/AP button, you can easily (from a soldering point of view) access to GPIO 18 and 20, check the last picture from this blog (in French):
TL-MR3020 slider

On a software point of view, though, it is a little bit more difficult, since you will have to comment the sw1 and sw2 declarations in the "arch/mips/ath79/mach-tl-mr3020.c" kernel source file and recompile your own OpenWrt to make them available as GPIOs, then use the bit-banged i2c over gpio kernel module.

EDIT: EquinoxFR has located the unused GPIOs 7 and 29 on R15/R17:

Thanks for your help guys !

I don't need the slider so I will probably use these.

I will hopefully find some time this weekend :-)

I will have to recompile openwrt anyways, as I have to enable the RTC support

looks like the same resistors for the same GPIOs as 703.

Yes, as far as I can tell, they have "compatible" BOMs (Bills Of Materials).

However, the TL-MR3020 features a few additional components  that were "missing" in the TL-WR703N (like "U4", IMHO a voltage/reset supervisor chip), but all other active components are the same.

It looks like most passive components have the exact same reference, some are just added for the TL-MR3020 and "missing" for the TL-WR703N.

As for connectors, USB, miniUSB/microUSB and Ethernet RJ45 are different parts, but bear the same reference.

A big difference though is that the TL-MR3020 is RoHs and CE/FCC compliant, the TL-WR703N is not (that's why it is so easy to desolder smile).

Hi everyone,

I just finished my mod. on router 3020 hardware version 1.6.

I'm really happy now with my nano router, hmm.. what next, maybe overclock the cpu to 600~800 Mhz would be nice big_smile

I'm really happy now with my nano router, hmm.. what next, maybe overclock the cpu to 600~800 Mhz would be nice big_smile

Let me find you some work here tongue

  • Integrate a High-Speed hub, so that the USB port works also with Low-Speed and Full-Speed devices

  • Boot as USB device in DFU and have the ability to flash the device from it

  • Do the same thing on an even smaller TL-WR703N smile

I own a mr3020 and it works as a audioplayer (with usb-hub with stick (extroot) and usb-audiocard) with mpd. by some reason I don't want to power it by micro-usb cable, so I have to solder power directly on the board. my question: where are the right soldering pad for power-5V and power-GND? of course I could solder it directly behind the micro-usb socket but there everything is so tiny... Are there better pads? by searching this a found some hints but I'm not sure if theses pads (see below) are the right ones and I don't want to blow my mr3020 up. any tips?
soldering power

Yes, they are!

I own both TL-WR703N and TL-MR3020 routers, which are "sister" designs, as they share 90% of their schematic.

I performed the reverse-engineering of the TL-WR703N PCB here: http://squonk42.github.com/TL-WR703N/

The R113 pad close to the Ethernet jack you chose for the Power 5V is "+5V0" on my schematic, and is directly connected to the miniUSB (microUSB for TL-WR703N) 5V power supply pin, so it is OK to use it for this purpose.

As for the GND round pads, there are only a single one in the TL-WR703N (the "GND" pad under the "SPI Flash" label in my schematic), and they deserve the same purpose: provide a SHIELD connection for an external antenna close to the different RF shunts J1/J2/J4. As they are all connected directly to GND, you can take whichever you prefer (I would avoid the one close to the populated J4, though) for GND and be safe.

I don't know if this is interesting for you, but as stated in my schematic, by populating the R113 using a big blob of solder, you bypass the U6 USB current-distribution switch. This allows supplying the router from the USB (not miniUSB) connector.

With this bridge I could power it up by the normal/big usb connector, right? So as I mentioned I'm using a usb-hub with stick and audiocard. Would it be possible to power mr3020 up through the usb-hub (opposite direction as usual: usb-power-adapter>usb-cable>usb-hub>mr3020)?

From an MR3020 point of view yes, but it all depends on the USB hub itself: hubs usually provide power to their downstream ports through overcurrent protection switch chips, but I dont think they will do the same for the upstream port...

What I said is mostly useful for self-powered custom boards, that can thus power the MR3020 through the same USB cable used to exchange data with the router.

I think I bricked my TL-MR3020 messing around with custom firmware build settings. My 3020 didn't like the custom CFLAGS I used and now the only led that lights up is the green led power light. I'm not able to ssh into it nor ping it. I thought I would try to use a USB to ttl serial connection so I purchased this one from ebay:

serial connector

I only have the TX, RX and ground connected to the router. Here is the serial output that I received when I connected to the router:

There's no other output, and it just stops right there. I attempted to type something into the Putty but I'm not able to. Does anyone know why I would not be able to type anything into Putty?

Edit: I was able to connect to the router via serial in linux. I get the exact same return and I'm not able to type anything into the terminal window.

Update: I was having problems with keyboard input because the usb to ttl device pin out diagram I was supplied with when I purchased the device was wrong. I eventually noticed the tiny print underneath the pins which provided accurate pin locations.

Follow the instructions here: http://wiki.openwrt.org/toh/tp-link/tl- … al.console
Note: you have to type in the tpl as soon as the "Autobooting in 1 second" appears on the screen.
If it still isn't working, you may need the resistor mentioned in the same section.

I'm trying to run pulseaudio on the MR3020 with a USB-audio sound card.

I've got http://downloads.openwrt.org/snapshots/ … actory.bin running, but can't seen to find a way to squeeze the pulseaudio files onto it.

I have also tried setting up an SSHFS (again not enough space to install the sshfs packages) so that I can remount overlay and run and get some more space.

What's the best way to buy just a bit more space to install the pulseaudio server and usb audio kmod?

(my china gps does not have an RTC and looses time after each start (--> gps fix takes long)

My GPS provides time before having a fix. I just ask gpsd for NMEA data, parse it with a small shell script and set the time the gps receiver reports.
After that, chronyd waits for a real fix (chrony wont work without fix for whatever reason) and then continues to adjust the time.

Not the first time someone asked for that.. I should write a wiki article or something..

//edit:
My point is: Perhaps your GPS too has the time before accquiring a fix. Have you checked the NMEA data, etc?

opkg update?

You should also state the 3g modem ur using!

nebbia88> that worked! Thanks!

luisfmoreira> ZTE - AC2726 or ADU-520A (for now i tried only ZTE)

I'm trying now to connect to ISP, but it isn't connecting. First time i did a mistake and used "3g" as proto, and there was an errors in logs. Now i changed to correct option:
config interface 'wan'
      option ifname 'ppp0'
      option device '/dev/ttyUSB0'
      option username 'card'
      option password 'card'
      option proto 'evdo'

but now when i run ifup wan it just doesn't work without any errors in logread... I feel that i did something wrong, but have no idea what exactly... sad

Reconfigured /etc/config/network finally:

===============
config interface 'wan'
        option _orig_ifname 'ppp0'
        option _orig_bridge 'false'
        option proto '3g'
        option device '/dev/ttyUSB0'
        option service 'evdo'
        option username 'card'
        option password 'card'

but getting this error in log:
