Thanks a lot! I already have some stuff working but I didn't have a script to detect the switch on boot! I will try to adapt your idea because I am yet to understand how UCI works therefore I will try to make it run a bash script !

Once again thanks

Hi,

I just bought a MR3020 and installed latest using the default web interface. I opened up the case and I'm trying to connect to it through the serial port, but I'm getting no response. Here's my setup:

http://i.imgur.com/xwdTb.jpg

I'm using the Arduino USB2Serial Light Adapter: http://arduino.cc/en/Main/USBSerial

I see the device appear/disappear when I plug it in and take it out:

danwang at danwang-mbp13 in ~
  ?  ls /dev | grep usb
cu.usbmodemfa131
tty.usbmodemfa131

I tried

screen /dev/tty.usbmodemfa131 115200

and got an empty terminal. When I type in screen, the RX LED lights up on the serial adapter, but nothing shows up. I've also tried minicom with similar results. Has anyone else had this or a similar problem?

Recently downloaded new firmware for my TP-Link TL-MR3020 from http://wiki.openwrt.org/toh/tp-link/tl- … ecommended but installation failed and now the router is out of order. Only power and WPS LEDs are on and I can't connect to the router neither by LAN nor by WiFi. Reset and powering on and off don't help.
Please advise if there are ways to restore the router.

Have u tried this :

http://wiki.openwrt.org/doc/howto/generic.failsafe

Thank you.
I can ping and telnet the router even without Triggering via Hardware Button or via keyboard key combination in a serial console. I  telnetted it several times with different commands (firstboot, mtd -r erase rootfs_data, rm -r /overlay/*) but without success. Below is the one of my tries:

Please help me to asses this situation and determine whether the router is irreversibly damaged or simply my knowledges don't allow me to restore it. Thank you very much in advance.

what you mean with "can't connect"?? i see a beautiful telnet shell, seems all working fine!
have you started with enabling wifi or installing Luci as Web GUI for example?

find everithing in the wiki:

You don't know how much i want to see this now

I have a problem with the latest 'aiccu' version 20070115-10:

From http://downloads.openwrt.org/snapshots/ … s/Packages:

    Package: aiccu
    Version: 20070115-10
    Depends: libc, libpthread
    Provides:
    Source: feeds/packages/ipv6/aiccu
    Section: ipv6
    Status: unknown ok not-installed
    Essential: no
    Priority: optional
    Maintainer: OpenWrt Developers Team <openwrt-devel@openwrt.org>
    Architecture: x86
    Installed-Size: 27112
    Filename: aiccu_20070115-10_x86.ipk
    Size: 27621
    MD5Sum: e4c0e6ea3761e65f905026edc577fbfd
    Description:  SixXS Automatic IPv6 Connectivity Client Utility

Problems:

1. It now claims to depend on 'libc' and 'libpthread' only. But in fact like the former versions it continues to also depend on 'ip', 'kmod-tun' and 'kmod-sit'. So unless I install those additional packages, the latest aiccu version won't work.

2. After installation of the latest aiccu version (within the latest firmware r32689 - 14.07.2012 downloaded from /snapshots/trunk/ar71xx/) there is no start/stop script '/etc/init.d/aiccu'. Hence I can't start aiccu the common way (/etc/init.d/aiccu enable) using the uci config file /etc/config/aiccu. Instead I have to start it manually by creating a suitable config file /etc/aiccu.conf (format different from /etc/init.d/aiccu) and then typing 'aiccu start'.

Sending this bug report to openwrt-devel@openwrt.org was replied by 'If you want to post to this list, you have to subscribe before'. Don't know how to subscribe, so I post it here.

Edit1: Just created a ticket: https://dev.openwrt.org/ticket/11861

Edit2: Okay, problem 1 got resolved in r32708 (https://dev.openwrt.org/changeset/32708), but problem 2 is not a bug but now defined as 'feature' (Read https://dev.openwrt.org/ticket/11592 for background information and draw your own conclusions). :-((

Thanks to everybody for great support but I couldn't manage to restore my router because I'm not much expirienced in such matters. But my brother helped me and now the router is okay)

I'm guessing you hadn't set a ssh passwd when you telnetted in: if you don't ssh is disabled. Just an FYI if anyone else has this problem.

Hello,

i have buy a mr3020 in version 1.7 , does anyone can confirm me that the firmware upload with web gui method work fine ? because on the wiki only 1.0 1.4 and 1.6 is confirmed

does the last trunk (from today) work fine ? ethernet support ?

(Last edited by new1 on 9 Aug 2012, 08:06)

I have two mr3020, one is 1.7 another is 1.4
both working fine.
I am also build my own firmware.

of coz it has wifi and ethernet support, what kind of question is it ?

i see in this topic problem with ethernet support with certain trunk version of openwrt.
so i would know if i can upload the last trunk of openwrt : http://downloads.openwrt.org/snapshots/ … actory.bin
with the web interface (not confirmed in the wiki with 1.7 version of mr3020) ... and all work fine after first reboot ?
(i don't want to brick my new mr3020)

does anybody can confirm that openwrt trunk work with v1.7 ?

(Last edited by new1 on 9 Aug 2012, 09:27)

up

That was a bug in previously trunk.
It is NOT about support problem.

If one of a MS-windows patch crash in your PC, then would you say your PC has problem to support MS-windows ?
Hah, that's funny.

In additional, trunk versions are UNtested.
If you are worry, stay in stock firmware.

For information  :
trunk R33053 from today  WORK great on MR3020 V1.7 (you can update the wiki)
uploaded by web  interface

Good job to all dev team

For your information, the latest is r33074
but the whole r330xx has wlan bug.
If you just use AP function, you won't see the bug.

i only use lan function
about last trunk, i just download it before i post my message .. so new trunk appear few minutes after ...

but my mail i just to comfirm good working of this trunk and with using upgrade firmware by mr3020 web interface (not mtd)

execuse me, i want to ask something... i just buy mr3020 yesterday.

i want to make extroot to work, already flash the openwrt-ar71xx-generic-tl-mr3020-v1-jffs2-factory.bin firmware and it success...
after that i have done several thing like edit some ip and making internet connection to work,
making usb work and mount it on /mnt/usb   (from /dev/sda3 )

when i try to install extroot, i've found that these 2 packages cant be installed from opkg (because it doesnt found)

block-extroot             ->            not found
block-hotplug            ->             not found

any idea?

this is my 'df'
rootfs                    2880      2812        68  98% /
/dev/root                 2880      2812        68  98% /
tmpfs                    14580      1824     12756  13% /tmp
tmpfs                      512         0       512   0% /dev
/dev/sda3              6927587      8194   6561947   0% /mnt/usb

i didn't found the  /overlay because i havent installed the block-extroot right?       

sorry for my bad english btw...

Study the openwrt wiki is a must for you !!  http://wiki.openwrt.org/doc/start

extroot is build-in in trunk version, no more extroot hotplug packages.

root@MR3020:/# df
Filesystem           1K-blocks      Used Available Use% Mounted on

Can you paste the output?

now i add option is_rootfs 1 in my /etc/config/fstab and reboot now it works....  the overlayfs:/overlay show....

config global automount
        option from_fstab 1
        option anon_mount 1

config global autoswap
        option from_fstab 1
        option anon_swap 0

config mount
        option target   /home
        option device   /dev/sda1
        option fstype   ext4
        option options  rw,sync
        option enabled  0
        option enabled_fsck 0

config swap
        option device   /dev/sda2
        option enabled  1

config mount

option device /dev/sda3
option target /mnt/usb
option enabled_fsck 0
option options rw,sync
option enabled 1
option is_rootfs 1

============================

now this is my df output

rootfs                 6927587      8194   6561947   0% /
/dev/root                 2880      2824        56  98% /rom
tmpfs                    14580        80     14500   1% /tmp
tmpfs                      512         0       512   0% /dev
/dev/sda3              6927587      8194   6561947   0% /overlay
overlayfs:/overlay     6927587      8194   6561947   0% /

thx u sir...

now the next step will  be

tar -C /overlay -cvf - . | tar -C /mnt/usb/ -xf -

to pivot whole /overlay to my usb storage which i already mount from /dev/sda3 to /mnt/usb

im going to try in few second.............

Good stuff. When you succeed (I'm sure you will), can you add it to the wiki, or post here? THere will be others who need the info.
