You need to add a proper network driver in U-Boot.
Network is initialized in U-boot, not again/later in OpenWrt.
pepe2k,
wrt400n is based on AR8236 switch
i thought driver already defined in include/configs/ap94.h
................
#define CFG_ATHRS26_PHY 1
#define CFG_AG7100_NMACS 2
................
Am I understanding wrongly?

It's probably not enough, look into Makefiles and make sure that proper driver code is compiled.

Which other driver are you referring to?
I focus on LAN port so I take a look there are only 2 drivers are important for this, athrs26 and ag7100. I check u-boot.map also shows those driver in address mapping. Also mii info can read AR8236 ID which I think nothing wrong with
the driver. I suspect athrs26_phy.c has something wrong, but I'm not familiar with the code.
Will you help take a look on the code if you have time?

I will, post somewhere your code. Does your code base on my modification?

pepe2k,
there are several source code and i check appears to have similar code
i guess might come from same source gemtek manufactured oem for linksys (wrt400n), vizio (xwr100)
and wr703n-uboot-with-web-failsafe
i didn't change any of the code, just compile from package
i even try u-boot.bin which already compiled from the package, and network already fails
i guess distributed gpl has already bugs
below are website links for getting the source
for wr703n-uboot-with-web-failsafe, need to replace makefile from wrt400n or xwr100
since wr703n makefile for AP121 platform instead of AP94
thank for your time to look at this
let me know any code which you suspect for fixing this bug and i will try on my side
since i have this router to test

WRT400N GPL
http://sourceforge.net/projects/officia … rt400n/v1/

Vizio GPL

Hi
I am new to OpenWrt but I want to use TL WR710n for my project. I need help and I found that this thread is very active.
I flash "openwrt-ar71xx-generic-tl-wa701n-v1-squashfs-factory.bin" to my wr710 via TL Link web page.
Then I can set new password via telnet. But I cannot SSH or other activity like checking ip address, network setting.
Probably I dno't know proper command line to view these info. I stuck at 'root@OpenWrt"/#'
Anyway I want to flash pepe2k uboot_mod firmware but I don't know what command line to use.
I know how to flash from TP Link firmware to uboot_mod because pepe2k stated in his post.
Yes, I have created tftp server.
Can someone help to get it done? I know that it is like spoon feeding, but I am a baby in terms of this tech knowledge.

Thanks advance.

you need to put space in between cat
run opkg update then install ssh
check where is partition name for your u-boot by doing cat /proc/mtd
then flash u-boot mtd -e <mtd0> write u-boot.bin <mtd0>
(assuming mtd0 is your u-boot partition)

it's not that easy, you need to keep safe your second 64KB of mtd0, you cannot flash the whole uboot like that!

read carefully first post AND LINKS in there..

anyway "install ssh" it's really funny xD

What's more... at this moment there is no way to update U-Boot from official OpenWrt images!
MTD partition with U-Boot is read only.

how about if add mask_flags = MTD_WRITEABLE in u-boot partition structure for openwrt ?

Remove, not add - you have there "mask_flags".

i'm not familiar with tplink router, but after i read pepe2k at 1st post,
i understand that u-boot only located the first 64K
in this case, need to dump the whole mtd0 using dd then
replace the first 64k with new u-boot then can flash whole mtd0
also like pepe2k said, need to remove mask_flags in openwrt u-boot partition stucture

...and recompile openwrt obviously... easy for a noob ^^

maybe it's simpler to flash dd-wrt, update uboot, then back to openwrt

Thanks Gentlemen for your advice.
Now I can check CPU info and MTD info
Then I try to run opkg and another problem pop up.

 
root@OpenWrt:/# opkg update
Downloading http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz.
wget: bad address 'downloads.openwrt.org'
Collected errors:
 * opkg_download: Failed to download http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages/Packages.gz, wget returned 1.
root@OpenWrt:/#

I think I need to change the path but I don't know how.
I read opkg manager but it is for intermediate and expert level.
Advice need is how to change path and which package has to be update.
Thanks in advance.

Thanks Gentlemen for your advice.
Now I can check CPU info and MTD info
Then I try to run opkg and another problem pop up.

I think I need to change the path but I don't know how.
I read opkg manager but it is for intermediate and expert level.
Advice need is how to change path and which package has to be update.
Thanks in advance.

opkg config in /etc/opkg.conf
however your opkg address is correct
just try in web browser http://downloads.openwrt.org/snapshots/ … ackages.gz
something wrong with your network connection

Hi dony71
You are right. Something wrong with network connection.
I need to explain what I have done so far, so that people can guide me and answer me proper answer rather than general answer. I am less than beginner.
I have wr710n and flash with "openwrt-ar71xx-generic-tl-wr710n-v1-squashfs-factory.bin"

I cannot set new ip address using 'set' command; set ipaddr 192.168.1.3
When I check newwork config, it did not change, show original address 192.168.1.1
Below are available commands and my activity.

root@OpenWrt:/# help
Built-in commands:
------------------
        . : [ [[ alias bg break cd chdir command continue echo eval exec
        exit export false fg getopts hash help jobs kill let local printf
        pwd read readonly return set shift source test times trap true
        type ulimit umask unalias unset wait

root@OpenWrt:/# set ipaddr 192.168.1.3
root@OpenWrt:/# cat /etc/config/network

config interface 'loopback'
        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'
        option netmask '255.0.0.0'

config globals 'globals'
        option ula_prefix 'fd61:77c0:ab41::/48'

config interface 'lan'
        option ifname 'eth1'
        option type 'bridge'
        option proto 'static'
        option ipaddr '192.168.1.1'
        option netmask '255.255.255.0'
        option ip6assign '60'

config interface 'wan'
        option ifname 'eth0'
        option proto 'dhcp'

config interface 'wan6'
        option ifname '@wan'
        option proto 'dhcpv6'

root@OpenWrt:/#

I notice that option gateway did not show, even if I connect wr71 lan port to my home router which gateway address is 192.168.1.254

I think that is the reason that I cannot run opkg.
Any suggestion?

Configuration in openwrt works with UCI. See http://wiki.openwrt.org/doc/uci and http://wiki.openwrt.org/doc/uci/network .

Thanks MBS.
I have gone through both and it doesn't solve my problem.
I used all possible commands and it did not work.

Both site give guide only, not detail enough for beginner like me.

@wnat could you please move your discussion/questions to another topic? This topic is about "U-Boot modification", not about UCI configuration and basics of OpenWrt. Thanks in advance!

I have the MR3020 and I am going to do a 16meg flash upgrade. I have ordered the W25Q128 that I will use for the upgrade.
Now I have read your thread (most of it ) and I wonder if any of you could verify my upgrade procedure?

I will first try the method without a SPI programmer.

This is what I have done so fare:

1. Backup mtd0 (128k) and ART
2. Today I downloaded u-boot_mod from GIT and built it using Sourcery CodeBench Lite Edition for MIPS GNU/Linux.
(Btw. Building using the OpenWrt Toolchain did not work. It gave me a file greater then 64k and I also got a error from build system)
3. I merged the 64k u-boot_mod I got from the build with the last 64k from the org mtd0 dump. (I have now a 128k u-boot_mod file that include my MAC and PIN etc)

This is what I will do when I get the flash:

1. Boot router into u-boot using serial cable.

2. Download u-boot_mod (128k) to RAM using TFTP

3. Do CS switch from 4mb FLASH to 16mb FLASH

4. Erase FLASH

5. Write u-boot_mod (128k) from RAM to start of 16mb FLASH

3. Start the new u-boot_mod and from web gui I should be able to upload my ART data?

If I understood the u-boot_mod correctly then I should be able to write to ART section from web gui?

Will this work so far? If not then I am a bit lost atm. There are so much to read about this.

At this point I should be able to upload the OpenWrt flash file to my new 16mb FLASH chip.
Can I just get the 12.09 image from here: http://downloads.openwrt.org/attitude_a … actory.bin
and upload it or do I need to get a new image that have the rootfs and rootfs_data file system increased to support the 16mb FLASH chip?

Hope some can help me out.

Regards

1)Backup the art partition
2)Write down the MAC Address
3)Flash the uboot on the SPI
4)Solder on
5)Hook up a serial USB console
6)Boot
7)Interrupt Boot to go into uboot env
8)Use the Set Mac Address save and reboot
9)Interrupt Boot to go into uboot env
10)Start mini httpd server
11)Computer connect to router set ip address
12)Choose upload ART
13)Upload ART
14)Choose upload Image
15)Upload OpenWRT Image
16)Reboot
17)Done

I know that problem. I will try to reduce final image a little.

Yes, using "art.html" page.

You can use any OpenWrt image (not older than AA).
FLASH size and type for TP-Link devices is recognized automatically.

Hi,

I would try to flash the u-boot of my new wr703n (V1.7).

I have found this "Howto flash u-boot" : http://zhujunsan.net/index.php/2013/08/ … or-wr703n/

I have some comprehension problem. It is right, with the method I must not use a serial connection?

My questions:
1) Shell script:
Can I juste copy paste in a file "ubootflash.sh"? And change with the name "uboot_for_tl-wr703n.bin" and the now MD5 (b1f1b7a14c28ea71ffac4f5d944c66cd)? (last release on 19.06.2013?)

---------------------------------------
- ubootflash.sh -------------------
---------------------------------------
#! /bin/sh
#high chance need have a change ...
UBOOT_NAME=uboot_for_tl-wr703n.bin
MD5SUM_SHOULD_BE="1f1b7a14c28ea71ffac4f5d944c66cd"
#need check the md5sum,any one byte in bootloader shoud right ...
CURRENT_MD5SUM_VAL=$( md5sum $UBOOT_NAME |awk '{print $1 }' )
echo "$UBOOT_NAME md5sum : $CURRENT_MD5SUM_VAL"
if [ $MD5SUM_SHOULD_BE = $CURRENT_MD5SUM_VAL ]; then
echo "$UBOOT_NAME md5sum check pass"
else
echo "###############$UBOOT_NAME md5sum check fail###############"
exit
fi
RAW_UBOOT_LEN=`wc -c $UBOOT_NAME | awk '{print $1 }'`
NEED_PAD_LEN=$((0x1fc00-$RAW_UBOOT_LEN))
#Generate a file used as pad ...
dd if=/dev/zero of=pad.bin bs=1 count=$NEED_PAD_LEN
cat $UBOOT_NAME pad.bin >tuboot_0x1fc00.bin
echo "Backup some config first,just like MAC address ..."
dd if=/dev/mtd0 of=./config.bin bs=1 skip=$((0x1fc00))
cat ./tuboot_0x1fc00.bin ./config.bin >uboot_0x20000.bin
---------------------------------------

2) Use Telnet:
I can first setup my 703n with a static address and I can connect on my local network or direct with my PC?

How can I download the *.bin file on RAM? I have read the RAM start address is 0x80000000, how can I do? ( "wget http:/my_local_PC_IP_adress/uboot_for_tl-wr703n.bin 0x80000000" or what else (name directory)?

I must also change the right access? "su chmod 777 uboot_for_tl-wr703n.bin"

3)
The script file can I also download on my wr703n with the same method (on RAM)? Or I can execute on my PC?

I execute juste with the command "sh ./ubootflash.sh" on which side (PC or wr703n?)

Thanks a lot for your help!
Best regards,
Xavier

PS: Sorry for my bad english!
