Topic: TP-Link TL-MR3420 V2 (2.1)

The content of this topic has been archived between 9 Aug 2014 and 22 Apr 2018. Unfortunately there are posts – most likely complete pages – missing.

That is what you want. "0" is 0 to 0.8V, "1" is 2v to Vcc (TTL specs)

The ttl levels for 0 are not of any spec I recognise. I'm wondering what would happen if you pull-down to GND with a 10K: that should fix the 0 level. Evidently the 1 level does not need a pull-up, as the signal is in spec even with no resistor.

Already tried with a 4.7k PullDown and the signal from the router is now ~700mV for "0" and ~2.8V for "1".

I will check the communication and come back if it's a success.

Success! big_smile

The trick, however is to follow these steps:
- disconnect the serial connection (Rx pin of converter from Rx of router, PullDown resistor disconnected)
- power the serial converter
- power the router
- start Putty (or whatever other program you want to use for serial console)
- wait a few seconds
- connect Tx pin of serial converter to Tx pin of router (with a 4.7k PullDown)
- connect Rx pin pin of serial converter to Rx pin of router (straight connection)

And the serial console should work now.
At least on my end it does smile.

I will post this on the OpenWRT Wiki along with the schematic of my adapter just in case someone doesn't want to spend money on the USB-TTL converter and has some soldering skills.

Thank you all for all the helpful ideas!

Tx and Rx are usually labeled with respect to the device they are on. Normally you would connect device A Tx to device B Rx and vice versa.
But aside from that nit-picking, congratulations on a successful outcome!

Hi, I bricked my MR3420 v2.1 too, cristi can you please send me some pictures of the connection you made to the touter pcb? I van't find nothing on the internet.. hmm
Thank you in advance

Would anyone could provide an v2 original firmware with out bootloader (thus the size should be 3.75MB / 0x3c0000) here to let me recover to the stock firmware?
Because the firmware on the official download include a bootloader which make the size larger.

In addition, The C55 (near the TLL port) should be short to receive input from console, other should be the same as V1...


Update: Well, I just got how to remove the boot loader, but it seems that I have damaged the ART (mtd4) and config (mtd3) part, the wifi could not come up. Would anyone upload them and give instruction for flashing it to ROM?

Hi,

https://www.box.com/s/kps8yu3wszywuhqzy0c3

Use these instructions for flashing.

Hope this helps smile.

Need your help with Serial Pin connection on broad, I have MR3420 ver 2.1 (http://i.piccy.info/i7/ab3087b8c163273205e28331e92bff42/4-66-286/11283924/3420_800.jpg).
I got a USB 2.0 to UART TTL 6PIN Module Serial Converter, in preparation for this mod. I have tried previously to restore OEM firmware back from openWrt and restoring failed bricking the router, if you can provide a diagram for the pin connection it would be great, i have tried failsafe with no luck.

Hi,
How can I reset my MR3420 V2 from openwrt to TP-Link firmware?
THX,
R

Download firmware: http://www.tp-link.com/Resources/software/TL-MR3420_V2_121206.zip (the filename contains "boot" & the size=4063744)
So
Cut the first 0x20200 (that is 131,584 = 257*512) Bytes from original firmware
Linux: dd if=orig.bin of=tplink.bin skip=257 bs=512 (source: http://wiki.openwrt.org/toh/tp-link/tl-wr1043nd )
Win: Hexedit will do.
Flash the stripped file (size=3932160)
Voila.

R

Thank you, thank you. This works.

Everything else I've seen on this subject appeared way too complicated than it should be, referring to Linux commands, etc. Not good if you're on Windows.

The only comment I would add is that the default IP of my router with stock FW is 192.168.0.1, whereas the OpenWrt FW uses 192.168.1.1 by default. If these values have not been changed, then after flashing from OpwnWrt to TP-LINK firmware, the OpenWrt window will just sit there "forever". Safest thing to do, I guess, is wait a few minutes, then open another window using 192.168.0.1. This will tell you if the flashing went OK, without interrupting activity on 192.168.1.1, in case it hasn't completed.

Greetings.
Can anyone help with testing?

https://dev.openwrt.org/ticket/13201

Someone wrote "It works!" and then all was quiet again.
(need logs, testing GPIOs)

I have TP-Link TL-MR3420 V2.1

and didn't have any chance with USB. I am using recent firmware trunk stuff. can anyone suggest anything? it simply won't power up any usb device i plugged. everything else works fine with v2 firmware.

Hello,
What "recent firmware"?

Hello !

im using openwrt several years, and using own sources too but i never used any patch.

I bought TLMR3420 V2.2, and need to use a second wifi. wifi dongle is a TL-WN722N.
this wifi dongle works fine with AA_RC1 on a TLMR3020 router with kmod-ath9k-htc module.

I install https://app.box.com/s/qebaprwq0798dyu19h1c/1/596285208 images.

everything works fine, but if i plug my wifi dongle after downloading their firmware the usb subsystem crashed.
(kmod-ath9k-htc module are installed)

so my question is:

how to dowload AA RC1 source from svn and how to apply V2 patch for that ?? (http://pastebin.com/gzf2VNhK)

(sorry my english wink )

hello again;

here some logs and info i can provide atm... what else should I look if you can direct me pls?

note1: I dont have gpio6 instead i have gpio4
note2: whatever i do (type echo 1 >... or plug the usb unplug it etc...) there is no activity in dmesg
note3: what i want is simply be able to plug a TP-Link's TLWN722N wifi dongle.
note4: I just noticed HondaRulez is trying to do the same thing.
note5: when I echo it changes over time the value. I mean it is jumping between 0 and 1 once i put a 1 there every few seconds.

wow! sorry I just upgraded to the latest version r37879

now when I plug the USB the led on the router lights up. dmesg says "[  216.860000] usb 1-1: new high-speed USB device number 2 using ehci-platform"

that's good news, that's never happened before. I cannot see radio1 yet anywhere but first I will play with what I got newly. Will let you know if have success or not smile thank you so very much smile

Hello

I confirmed SAMSUNG K4H511638B DDR RAM works in MR3420 V2.2

For TP-Link's TLWN722N you need "kmod-ath9k_htc" module too.

then run command "wifi detect" to show new wifi interface parameters.

this wifi dongle works "any" openwrt version (include current trunk) which i try'd excep on tlmr3420 V2.2 wit AA RC1 sad

so, i will compile own image of AA RC1
but I can't  apply V2 patch at this moment..


here is my log if USB wifi dongle is present at boot:

Hi, all
After r37855 (before to support USB implemented Dioptimizer) I got a problem with Wi-Fi
deauthenticated due to inactivity (timer DEAUTH / Delete)
That does not happen when connected wired clients, only Wi-Fi and Wan.
Is just me or somebody also encountered?

reopened ticket

The device was buggy with memory - the region around 20 MB.memtester did not identify, help testing of u-Boot

Hello, what better firmware *.bin for ver 2.2 now? Thanks!
