Hello.

I've successfully run OpenWRT from trunk on this router (TL-MR3220v2).

I have a problem with USB on this router. I have a custom board with FT232RL on it. It worked great on TL-MR3220v1. Now it also works, but USB host on router is crashing.

When I run my program on it, You can see ongoing communication on LED's (USB led on router is flashing, RX led on my device is also flashing). After a while (sometimes 10s, but not more than 10 minutes) communication stops. USB LED on router is constantly on, RX LED is off. I's a hardware fallout for sure. When I connect it through USB Hub it works a lot better. But its also not ideal. When i start some 230V device close to cable (fluorescent lamp 20W) its also crashes.

I found that USB socket shield is connected through 1nF capacitor. It's different than in devices I've had before. As far as i know this filter is for high freq EMI. I've try to connect it directly to GND, but it didn't helped.

found my answer here https://forum.openwrt.org/viewtopic.php … 68#p190168
Any clues?

Take care.

Hi,

First, big big thank you to all the contributors of this thread, my MR3220v2 is finally doing a good job here. Following this thread since weeks.
So many thanks to cindy, nebbia88, MBS and others.

All firmware images linked by contributors in previous posts worked fine, and I finally took the option to use the trunk version, to manage the additional packages to install by myself.
Success

Here is the only issue I encountered is the USB port. Same problem, connection with 3G USB modem (tested several models) is lost at random interval time - --> can see a reset on USB port, probably EMI or not enough power.
Using an active USB hub solved the problem. At this moment final user is reporting an uptime of 10 days without disconnection.

I am new to Open WRT or any type of alternate firmware. It is happy to see that MR3220 is now supported by Open WRT. I have a new MR3220 which version in V2.2 can I use firmware from cindy.wijaya with my router ?

Hello!

I am trying to build a custom FW for TL-MR3220 V2.

The first problem I am facing is, that I can't find the option for V2 in Target Profile, just TP-Link TL-MR3220.
Is this normal?

I have AA revision 35685.

After the compilation is finished I see following files in .../bin/ ar71xx dir:

-openwrt-ar71xx-generic-nbg460n_550n_550nh-u-boot.bin
-openwrt-ar71xx-generic-root.squashfs
-openwrt-ar71xx-generic-root.squashfs-64k
-openwrt-ar71xx-generic-uImage-gzip.bin
-openwrt-ar71xx-generic-uImage-lzma.bin
-openwrt-ar71xx-generic-vmlinux.bin
-openwrt-ar71xx-generic-vmlinux.elf
-openwrt-ar71xx-generic-vmlinux.gz
-openwrt-ar71xx-generic-vmlinux.lzma
-openwrt-ar71xx-generic-vmlinux-lzma.elf

I am assuming that the FW for flashing the router is "openwrt-ar71xx-generic-root.squashfs"
and that it contains the support for V2, although there is no V2 in the FW name?

Two more questions:

-what is the "64k" FW for?
-where can I find the guide for "safe flashing"? Till now I have been working only with Asus WL500g and Linksys NSLU2.

Thank you,
Davor.

JFFS2 rootfs image for flash chips with 64k eraseblock size and JFFS2 rootfs image for flash chips with 128k eraseblock size.

PVi1, thank you for the explanation.

Can you tell me, which FW should I use to flash MR3220?

No, it's openwrt-ar71xx-generic-tl-mr3220-v2-squashfs-factory.bin

Found the answer here - https://forum.openwrt.org/viewtopic.php?id=32219 - after compiling vith V=99.
Images are too big, but there is no warning when just running make.

Friends, it's working without any problem. I think V2 and V2.2 are using same hardware. Even TP-Link using same firmware for V2 and V2.2

Having recently bought a MR3220 v2, I want to have a UI for Wake on Lan (WOL), similar to what I had on my WRTL54G with DD-WRT (which has a whole tab dedicated to WOL in the router's configuration UI). I've read that this could be accomplished on the MR3220 v2 through OpenWRT+Gargoyle or OpenWRT+Lucy+WoLPackage.

The problem is that I'm completely new to OpenWRT and, although I've already identified (what I think is the) right .bin to upgrade (openwrt-ar71xx-generic-tl-mr3220-v2-squashfs-factory.bin), I have no clue on how to install the UI (Luci or Gargoyle). Additionally, due to my lack of knowledge in SSH/PuTTy, there's no way I can do it without a comprehensive step-by-step guide.

Would it be possible for someone to post some sort of compiled image of the latest trunk (openwrt-ar71xx-generic-tl-mr3220-v2-squashfs-factory.bin) with a UI that includes WOL? Is this possible, at all, or am I asking for the impossible?

Thanks!!!

Here you go:
OpenWrt Barrier Breaker r35096 / LuCI Trunk (trunk+svn9605)
http://www46.zippyshare.com/v/93902503/file.html

md5sums

f3f85c27ee5d1b63e151d282b2263af2  openwrt-ar71xx-generic-tl-mr3220-v2-squashfs-factory.bin
0f8485841babb7d860bd75cf07596411  openwrt-ar71xx-generic-tl-mr3220-v2-squashfs-sysupgrade.bin

It's the current one that I use. I don't have WOL installed, but you could try to install it manually. It's NOT the newest one, but works just fine for me. It includes LuCI and a little of other features like auto turning on wifi on boot, 3g usb support (haven't checked because i dont use it much), & other small ones.

Package that you would probably need is luci-app-wol.

what's the problem?

regards.

Thank you to everyone who have compiled and shared their builds.  I have tried pretty much all the builds here...

I am very new to openwrt..I have the MR3220 V2 ..But i have one problem, all the builds here leave only so much room to install anything else.. biggest room i had left was around 232 K with one of cindy's builds..

I need to install libstdcpp and libpthread.  And I need to have custom software for around 404 KB.  I would only need to wifi to work and regular wan and lan.  I would need the bare minimum stuff on it.. I wouldn't need any bells or whistles on it.

I belive these are packages I could do without.. (in cindy's builds..aarc1)

blkid
block-mount
chat
ddns-scripts
huaweiaktbbo
kmod-atm
kmod-fs-ext4
kmod-fs-vfat
kmod-nls-xxxx (I am not sure what they are for)

I am sure there more packages. but i couldn't be sure if they are need to router to work ..

If some one would be kind enough the compile the build with enough space for the package I  listed above.. I would appreciate it very much.  Thank you.

Hello, someone so good as to make me a fresh Trunk just with e398 huawei support and wlan / lan?

Start a NEW thread Please!!

Hello my friends. Please compile DC + + firmware or show how to do it. Thanks to those who help)))

can someone pls do test of write and read  speed's on a usb storage using ftp/samba/http ... on this router thank's in advance

thank's brother

hi everybody
I will probably buy a MR3220 or MR3420. but before I need to know if everything I need is working. I red this thread but I'm still unsure which firmware I should use. Is it the aarc1+patch by cindy? or trunk-version?
I need working usb soundcare, usb storage, wifi routed client mode
@viraga84: I have already build this with a MR3020. now I want to build it with MR3220. do you have it built already? which firmware?
thanks a lot
j

Hi! everybody.

How do I flash Open WRT on this router? Can some one give step by step instructions. I need to have USB and ehternet working. Wifi is not such a big isuue. Do most USB devices work? Is it risky to do this?

Hi!

I'm sorry because of the late answer. I don't have time for this project, rarely check the topic and the router data sheet but it is still in trunk status. I use the trunk-version firmware but the memory wasn't enough to install the programs requisted for internet radio. I bought an usb hub now and I have old usb sticks to expand the free space but have not tried these yet. The trunk firmware works nice for me (internet on PC and wifi are OK). If you build the radio I accept information happily. Thanks.
Have a nice day!

Could anybody please provide ImageBuilder for MR3220v2 patched 12.09 final?
I tried to build it myself, but met three errors in a row, and i can't find any solution to the last one.

I've installed latest 14.07 version -- http://downloads.openwrt.org/barrier_br … x/generic/ -- via OEM browser and it's working like a gem!
