Thank you. I will try. What do you think about links, thats i was posted? About  Bullet M? But theirs size is other, than tp-link's.

Hi,

The TL-WR941ND v4 should be working with the 'openwrt-ar71xx-tl-wr841nd-v5-squashfs-universal.bin' image. The problem is that you have used an old snapshot, and the support for the Winbond W25Q32BV flash chip has been added only with r19536. You should try a newer snapshot, or you should build your own image from a fresh checkout.

Regards,
Gabor

Is it true, for my device?

good news!!
you may get further test

the wireless and the led lights
do they work well??

Yes, led lights work well. Wireless will test after 1-2 hours. How to disable update from internet before compile?

(Last edited by alif on 19 Feb 2010, 21:42)

Ok. wireless work is good)) But how to save all settings?) I am searching.

My WR-941ND v2 sports a 2x5 pin serial header instead of the 4 pin 1-line header that is found on the wiki (at least I hope it is the serial port). Did somebody figure out its pinout? Is the same resistor to bridge?

look here http://www.dd-wrt.com/phpBB2/viewtopic. … eeb8b34cb1

Yes, that's it, thank you very much for the pointer.
Although it is not entirely clear from the post how lark counts the pin numbers: when he mentions pins 1...5, is he referring to the top row starting from the marked pin or is it in zig-zag as in the standard (?) pin numbering scheme?

How could use with the USB host ?
My hardware is TL-WR941Nv4, run profile "WR941NDv4" well, which use "mach-tl-wr741nd.c" in the kernel.
And I had add function "ar71xx_add_device_usb();" at "tl_wr741nd_setup", so I can "lsusb" in console to got following message:

And I have solder [s]R278,R277,(updated, delete it)[/s]R185,R183, R713,R712,R711 directly.(Is it correct? I do not solder the resistor but short pass)
But the USB device can not find yet.
Is there any advice?

R713, R712, R185, R183, R711

(Last edited by arrowworld on 21 Feb 2010, 05:40)

TL-WR941Nv4 direct solder resistor should be R713, R712, R185, R183, R711(GND)
Then R713 connect to CPU pin of U74, R712 connect to CPU pin of U73.
But Here lack 5V Vcc, How could get 5V from 9V Vcc.
http://www.dd-wrt.com/phpBB2/viewtopic. … p;start=15

But here is not any update
Could someone help it ?

new progress on the usb about TL-WR941Nv4, I have got below message now -_-, connect as the last my post.
but, I use with a hard-disk which supply 5Vcc with another USB host.
So, How to get 5Vcc is the critical work.

(Last edited by arrowworld on 21 Feb 2010, 05:55)

Get 5Vcc, Could use "78M05" ?
http://www.datasheetcatalog.com/datashe … 8M05.shtml
Solder it at "U18" ? Need your help

Should someone else be interested: my scope told me that the "zigzag" numbering is the right answer. Thanks again.

lark said: P1 is RX, P2 is TX. R356 is all you should need to bridge.
     just to short pass the R356,

Can you post photos, how you solder it?

I am sorry) I asked arroworld)

For here is no camera, I capture a photo with my thinkpad-x200, seems not clearly([s]refer to attached image::I'm finding how to attach it[/s]).
The CPE did not stable while short pass all of the resistor, it will reset the device,(e.g. the DM9601 net device)
So I solder 0.1Ohm resistor to R713 and R712, then solder 100pF capacity to R278 and R277, now my DM9601 net card is so stable. (short pass for I have no resistor before, I bought some equipment for research the wrt these days, e.g. digital multimeter)
Oh, so sad, I have not found out any way to post it, fail on flickr.com yet.
The picture could not show with me, maybe anyother could show it?

Now, I have make out a 5V power supply with LM2576t-5(made by motorola), sit on another board, and connect the USB connector's VCC,GND to the power-board.
the datasheet is at: http://www.datasheetcatalog.com/datashe … 6T-5.shtml, the layout referrence at page 22.

Hello!

I'm trying to get the USB port of my WR941ND working, but didn't succeed yet. I have a V 3.0 device, hardware revision 1.2.

I soldered 33 Ohm resistors for impedance matching to R1000 and R1001, added a 7805 and a 100uF capacitor to provide +5V to the USB port. Power supply works well. I suppose that D100 and D101 are some kind of surge protection, so I omitted them.

Then I checked the data lines with a multimeter. Between R1000 and GND I measured 0.7V dc and an ac value of about 1.2V which looks promising to me, as it shows that there is a pulsing signal on the line.

I repeated the same test for R1001 and measured 3.3V dc and 0V ac, which looks more like the high level of a gpio line than an USB data signal. I checked all connections twice, but didn't found anything: no shortcuts, no missing components.

As I don't have a datasheet of the AR9132, I don't no if there is any kind of i/o-pin-sharing, which requires a pull-up / pulldown resistor to be set in order to connect the USB data signal to the corresponding i/o-pin.

The kernel is already modified, too. I added scsi_mod, nls_base, usbcore, ehci_hcd, ohci_hcd and usb-storage. In order to get the usb-controller be recognized by the kernel, I had to add 2 lines to the source file mach-tl-wr941nd.c. First an additional header-file must be included:

#include "dev-usb.h"

Second the initialization routine of the usb-controller must be called:

static void __init tl_wr941nd_setup(void)
{
    u8 *mac = (u8 *) KSEG1ADDR(0x1f01fc00);
    u8 *eeprom = (u8 *) KSEG1ADDR(0x1fff1000);

    ar71xx_set_mac_base(mac);

    ar71xx_add_device_mdio(0x0);

    ar71xx_eth0_data.phy_if_mode = PHY_INTERFACE_MODE_RMII;
    ar71xx_eth0_data.phy_mask = 0x0;
    ar71xx_eth0_data.speed = SPEED_100;
    ar71xx_eth0_data.duplex = DUPLEX_FULL;

    ar71xx_add_device_eth(0);

    ar71xx_add_device_usb();

    ar71xx_add_device_dsa(0, &tl_wr941nd_dsa_data);

    ar71xx_add_device_m25p80(&tl_wr941nd_flash_data);

    ar71xx_add_device_leds_gpio(-1, ARRAY_SIZE(tl_wr941nd_leds_gpio),
                    tl_wr941nd_leds_gpio);

    ar71xx_add_device_gpio_buttons(-1, TL_WR941ND_BUTTONS_POLL_INTERVAL,
                    ARRAY_SIZE(tl_wr941nd_gpio_buttons),
                    tl_wr941nd_gpio_buttons);
    ar913x_add_device_wmac(eeprom, mac);
}

The syslog output looks quite good so that I'm pretty sure that nothing is missing.

Hello!

I'm still trying to get the USB-port of my WR941ND working. As the board of the V3 is different than the one of the V4 I need some additional information. Could anyone who has applied the modifications describe the circuit a little bit more, please?

According to the post R712 and R713 connect the USB-header to the CPU. Is that correct?

As R711 connects to GND, it seems to be a pull-down resistor. Is it connected to the CPU, too? (Which pin?)

Soldering a capacitor to a resistor's pad (R277 and R278) seems weird to me? Does anybody know a little bit more of the function of this components? To which other components are they connected? Are they related to the power supply ciruit?

What is the function of R183 and R185? Are they pull-ups or pull-downs?

Thanks in advance!

Sincerely,

Mausi

Hi,

I just received a WR941ND it has version nr v4.1
What image can I use to flash it? Anyone tried to flash V4.1 ?

Many tnx.

Have the same question ....

Anyone?

Brgds,
S.

I have standard TP-LINK firmware and i want it to upgrade with openwrt firmware.
As i can see from:
http://downloads.openwrt.org/snapshots/ … actory.bin

Is it going to work if i flash it over webUI with openwrt-ar71xx-tl-wr941nd-v4-squashfs-factory.bin file?

Brgds,
S.
