@openewrtn00b

Your modem driver is not properly installed , try install usbutils package.

opkg update
opkag install usbutils

you installed
kmod-serial-option ?

post opkg list-installed

You should update the firmware from the beta2 (of mid-October) to rc1 (end of November). I didn't check if there was anything specific fixed for your modules, but there were some fixes to the generic network interface logic.

(Last edited by hnyman on 27 Dec 2012, 11:45)

agreed, then lsmod | grep usb
Looks like some part of usb-serial is missing.
Have you got:

kmod-usb-serial, and
kmod-usb-serial-option, and
kmod-usb-serial-wwan, or
kmod-usb-acm i.s.o. the last two, depending on dongle/phone hardware.
kmod-usb-serial-option is not available for 2.4 kernel, install kmod-usb-serial and put a line equivalent to "usbserial vendor=0x12d1 product=0x1003 maxSize=2048" in /etc/modules.d/60-usb-serial)

thanks for helping me, guys!
I found four firmwares:
http://downloads.openwrt.org/attitude_a … actory.bin
http://downloads.openwrt.org/attitude_a … pgrade.bin
http://downloads.openwrt.org/attitude_a … actory.bin
http://downloads.openwrt.org/attitude_a … pgrade.bin

which one is for me? Do i understand correctly that i can upgrade via web GUI (System-Backup/Flash Firmware->Flash new firmware image)?

Squashfs as the file system. Sysupgrade (to upgrade from a live Openwrt system). Yes.

Just flashed my mr3020 v1.7 with OpenWrt 12.09-RC1 (Attitude Adjustment) and everything is working great. Updated wiki with this info.

Hi,

I want to upgrade from attitude adjustment 12.09-beta to 12.09-rc1.

Is there a way without serial-cable?

How must I do this?

I hope anyone can help me. :-)

Sure :-)

Just transfer the openwrt-*-sqashfs-sysupgrade.bin image to /tmp (ram disk) and use sysupgrade command.

wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-sysupgrade.bin
sysupgrade -n /tmp/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-sysupgrade.bin

I did it so. Flashing worked but now I can't login via SSH any longer.
SSH responds on 192.168.1.1 but my old root-pwd doesn't work and no any default combination.

Via WebIf I also can't login - on port 80 no service is listening - maybe it's because before flashing I removed luci!?

What can I do now?

Ah, via telnet it works - no password was set.

But luci is not installed any longer - which file must I flash to get a clean installation with all default packages or would it better to flash now the original TP-Link firmware and then reflashing OpenWrt?

(Last edited by onlineuser on 1 Jan 2013, 17:55)

You flashed the trunk, NOT the 12.09-rc1, this is why you don't have LuCI.

Do the same thing again with the AA branch, whose last revision should be the RC1.

Thanks.
What do you mean with "AA branch" (ahhh - AA ==> Attitude Adjustment)?

Hm, in meantime I flashed the original TPLink firmware and now I will flash rc1. :-)

Now I took:

http://downloads.openwrt.org/attitude_adjustment/12.09-rc1/ar71xx/generic/openwrt-ar71xx-generic-tl-mr3020-v1-squashfs-factory.bin

I needed some more space for openvpn.

Is there a way to use a sdcard for getting more space for openvn?
The 3020 has a usb port and the original firmware also supports usb sticks.

How can I tell openwrt to use external space (I can remeber from NSLU with unslung, but there it was complex).

(Last edited by onlineuser on 1 Jan 2013, 21:17)

Everything is in the Wiki
http://wiki.openwrt.org/doc/howto/extro … ment.trunk

Ok, thanks but these packages takes a lot of space - does it work on a router with 4/32 MB or does it only work on 8/32MB or higher?

The kernel (and all packages in general) tend to take more and more space as time goes by, hopefully not bloat but real new functionalities...

But this unfortunately is making the 4/32MB setup less and less usable

It is now difficult to have a firmware with LuCI (integrated by default in the AA branch) and still have enough space to be able to fit the required packages to pivot the root onto an external flash!

The only practical way out is to compile a firmware by yourself and put LuCI as an optional package and btw, put all the required packages for pivot root built-in.

@Onlineuser

If you need more space you can configure and use extroot. Look it up in the OpenWrt Wiki.

Yes, but the problem is now that the AA branch comes with LuCI built-in, and that LuCI + everything required to get an extroot doesn't fit in 4MB Flash any more!

Then it's time to build AA by yourself!!

it depends..

installing only

opkg install block-mount kmod-usb-storage kmod-fs-ext4

you get:

root@OpenWrt:/# df
Filesystem           1K-blocks      Used Available Use% Mounted on
rootfs                    1088       632       456  58% /

so it's ok... i used to install also e2fsprogs, to partition and format the usb disk, now it's impossible.. you need to format it on your pc ^^

Cool!

When I use a usb-card-reader with a sdcard, do I need to take kmod-mmc instead of kmod-usb-storage?

Which partitions must be created on sdcard?

No.
You need kmod-usb2 & kmod-usb-storage + a filesystem kmod.

one ext2/3/4 partition and one swap partition ( then you'll use mkswap /dev/sda2 if you want..)

I use MiniTool Partition Wizard on a Windows PC for this :-)
