It's time to do a release for those of you who want to try out openwrt on your wdr7500.

Tested, working:

Ethernet
dual channel 2.4Ghz 802.11n wifi
Usb ports + mounting ext2 filesystem
System led lights (except for the 5ghz led)
ssh, telnet
Configuring the system using Luci
Samba

Tested, not working:

5ghz 802.11n wifi and wireless ac. It should be possible to enable this once the ath10k driver gets into the kernel
tri-channel wireless, openwrt only supports dual channel right now.

Untested, may work:

Mounting ntfs and vfat filesystems
Wireless at >150mb/s. The best any of my computers can do is 150mb/s
WPS/QSS switch
Any wan connections other than dhcp e.g.PPPoE

So if you can give up 5ghz wireless n and wireless ac feel free to try out my firmware from here:
https://www.dropbox.com/sh/2ttawsgz669wvnd/Le0XrPvPXY

The only "supported by me" way of flashing this is to break into the bootloader with a serial cable tftpboot the factory image into ram, erase the nand from 0x20000 +0x7C0000 and write the factory image to 0x20000 +0x7C0000.

Hi,qca9588.
I've flashed your firmware on my new bought wdr7500 v2.Booting is not ok.Notice that I changed flash to a 16m mx25l12805d.

You also said your board is a v2? Is that a chinese imported one like mine? I didn't know there was a v2 out. The only board I know of like the wdr7500 is the Archer C7 which is the rest of world version of the wdr7500.

We must have the same model.Mine is bought from jd.com as this:
http://wikidevi.com/wiki/TP-LINK_TL-WDR7500
I soldered mx25l12805d because original 8m flash is not enough for me.But the factory firmware run nicely on this chip.I will try to resolder en25q64 back home to see if it is the flash chips compatibility issue.
By the way,your repo on git doesn't produce a workable firmware like openwrt-ar71xx-generic-tl-wdr7500-squashfs-factory.bin.

If it's the same model it should be alright. With the original chip I expect it to work like mine.

Did you do a backup of the original flash memory? I think I may have messed up my art partition and would be interested in seeing what a normal one looks like. My wifi mac is coming up as 00:02:03:04:05.

How did you make the 16M flash chip? You will have to change the partition layout if you want it to work correcty. The Art and config partitions will have to be moved to the last 128k of the flash memory and you'll have to edit the kernel driver and the script that builds the images.

How did you set up your .config file? Did you only target the wdr7500? For some reason if you want images to be built you have to select all image targets, I haven't figured out why yet.

Update:I've resoldered en25q64 and flashed your firmware.This time booting is pretty smooth.I do a copy test through ftp and got 15m/s(ext4) which seems not bad. But when I try to start wifi,ttl said:

Good to hear you got it working using the old chip! I set up wifi on my router using the luci interface and didn't see that error happening.

root@OpenWrt:/# wifi up
'radio0' is disabled
'radio0' is disabled

Maybe it only happens when you try to turn wifi on when it is disabled?

Looks like a null pointer reference coming from the kernel. I never said there wouldn't be any bugs

I haven't tried flashing the Archer C7 firmware onto my wdr7500 yet but I think you've flashed the firmware incorrectly ranfish. This part of your dump suggests that the image wasn't generated and/or flashed properly.

I managed to flash the Archer-C7 firmware onto my wdr7500 with only one slight problem. The same issue I was seeing before where the wan port is on the 4th lan port instead of the lan port. An easy fix by changing /etc/config/network to:

config switch_vlan
      option device 'switch0'
      option vlan '1'
      option ports '0 2 3 4 5'

config switch_vlan
      option device 'switch0'

Last I heard about ath10k was on the linux-wireless mailing list http://marc.info/?l=linux-wireless& … 09&w=2 I don't have any wireless ac devices yet so I'm not planning on backporting it to linux 3.8. Better to wait for linux 3.11/12 that should have stable support for it.

Hey, i set up my 2 new archer c7 with openwrt trunk version from 10th july.... Was surprised how quick the device was supported... but i notice a bad behaviour in failsafe... I misconfigured the switch and wanted to boot to failsafe. led is blinking fast, computer has ip 192.168.1.2, but the router keep beeing unreachable... even with tcpdump there is no output at all "sudo tcpdump -Ani p6p1 port 4919 and udp"

Any ideas how to debrick it? unfortunatly i have no jtag....

It looks like the most recent version of compat-wireless that just went into openwrt mainline has ath10k support. So as long as it's being compiled into the kernel and the firmware is present on your openwrt-7500/archer-c7 wireless ac + 5ghz should all work!

If you read http://wireless.kernel.org/en/users/Download/stable
compat-wireless has been renamed to compat-drivers since a while now, since it contains Ethernet and Bluetooth as well

If I then go to http://drvbp1.linux-foundation.org/~mcg … backports/ and look at backports-20130607
I find no ath10k

where do we have to look?

The latest compat-wireless drivers used by openwrt are available here http://mirror2.openwrt.org/sources/comp … 3.tar.bz2.

It has the ath10k drivers in it but they are currently not built by default.

I've opened a ticket to get them supported at https://dev.openwrt.org/ticket/13704

Archer C7's port sequence is the same as wdr7500 v2

I'm quite confused.... so may I just flash the Archer C7 V1 firmware on the TL-WDR7500 router? Will there be a problem of LAN/WAN ports?

It seems in the WDR7500 firmware interface (in Chinese) the hardware version is shown as v2.0.

BTW qca9558, may you share how to change the /etc/config/network file? I'm totally new here...

All I'm looking for is to change the Chinese interface to English...

Thank you all very much~~~

oh, BTW, does the DDNS like Dyndns in the Archer C7 firmware works on the WDR7500?

I got me one WDR7500 today but I seem to have gotten a faulty unit. When using serial and booting into uboot I cannot get any functional network communication. I have tried all of them but cannot ping or upload new firmware. The leds are blinking when sending ping but no success otherwise. What LAN port is default in uboot and is there any configuration to be done?

I don't know, I meant to say flashing the openwrt build of Archer C7 firmware onto the TL-WDR7500 worked fine. This isn't the right place to be talking about using tp-links firmware.

Learn how to use vi or install nano and edit the file so port 1 and 6 are on vlan2 and 0 2 3 4 5 are on vlan1

I could tftp using any of the yellow ports I think. Make sure you set hostip and serverip before tftping e.g.

set ipaddr 192.168.1.100 
set serverip 192.168.1.101; 
tftp <imagefile>

Make sure serverip corresponds to the computer you're running tftp on.
