-==== Serial ====+==== GPIO mapping ==== 
 +In OpenWRT system there are 18 GPIOs available. However gpio0, gpio1 are used by system to control LEDs and gpio11, gpio12 as input buttons. To be able control these IOs directly it is necessary to unload modules ''leds_gpio'' (gpio0,gpio1) and ''gpio_buttons'' (gpio11,gpio12). 
 +Next step is to export control files of each pin: 
 +  echo N > /sys/class/gpio/export 
 +Where N is GPIO number. This will create directories with control files in /sys/class/gpio/gpioN 
 + 
 +I have discovered this IO maping:

 + 
 +For versions v4.x using AR9331 see reverse engineered pinout on [[toh/tp-link/tl-wr703n/ar9331_pinout]] . 
 + 
 +==== TL-WR741ND v1.5 ==== 
 +I have this version and I found working out of the box only backfire r22689 http://downloads.openwrt.org/backfire/10.03.1-rc3/ar71xx/openwrt-ar71xx-tl-wr741nd-v1-squashfs-sysupgrade.bin 
 + 
 +==== TL-WR741ND v1.9 ==== 
 +Because of a change in the flash chip to the EON EN25F32 flash chip on the hardware version v1.9. A new patch to support this flash chip was created. You can either compile openwrt trunk or add this patch:  
 + 
 +https://dev.openwrt.org/changeset/23058 
 + 
 +To your openwrt 10.03 source files and compile openwrt. 
 + 
 +==== TL-WR741ND v2.X ==== 
 +Device works with Backfire 10.03.01 and latest [[http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-wr741nd-v2-squashfs-factory.bin|trunk image]] and also with[[http://www.gargoyle-router.com/downloads/images/ar71xx/gargoyle_1.4.0-ar71xx-tl-wr741nd-v1-squashfs-sysupgrade.bin|**Gargoyle** build]], no flaws discovered. 
 + 
 +==== TL-WR741ND v4.x ==== 
 + 
 +Version 4.x has changed to use the AR9331 SoC, and is supported by the trunk version.\\  
 +Probably the hardware of all v4.x versions is identical. 
 + 
 +After installation of r31249 + LuCI, 604KB flash are free for additional packages.

 +  *  Rotuer consumes between 0.5W and 1W, depending on the power supply voltage and load. 
 +  * The power adapter is rated 9V @ 0.6A . The router can be powered from a battery.  
 +  * V2 and V4.3 versions of the router contains an MP1482DS step down voltage regulator, with the voltage range from 4.75V to 18V. This are absolute maximum ratings, other components might not be able to withstand this voltage range. 5V to 15V should be a safe range (don't try this on other versions than V2 or V4.3 if you aren't sure)

 +==== U-Boot 1.1.4 modification for routers ==== 
 +Forum member [[https://forum.openwrt.org/profile.php?id=72549|pepe2k]] made a modification of **U-Boot 1.1.4** for **Qualcomm Atheros** SoCs based devices (the project is still being developed, so new devices and SoCs will be supported in the future). Up to date information, binary images and sources can be found on official [[https://github.com/pepe2k/u-boot_mod|GitHub repository]]. 
 + 
 +This modification started from [[http://code.google.com/p/wr703n-uboot-with-web-failsafe/|wr703n-uboot-with-web-failsafe]] project, but supports more devices, all modern web browsers, has a lot of improvements and other modifications (like U-Boot NetConsole, custom commands, overclocking possibilities etc.).

Comment: to get the serial connection work reliably, I had to connect a 10k pullup resistor between the TX and the 3.3V pin. This is because the TX pin is connected to a voltage divider (2x5.6k) and a capacitor is put between the real pin and the TX connector.

Hint: it is possible to have a serial connector outside your router without drilling holes through your nice case. The trick is threading the 4 serial cables through the vent on the side of the router before putting back all the parts and closing the case.

-In OpenWRT system there are 18 GPIOs available. However gpio0, gpio1 are used by system to control LEDs and gpio11, gpio12 as input buttons. To be able control these IOs directly it is necessary to unload modules ''leds_gpio'' (gpio0,gpio1) and ''gpio_buttons'' (gpio11,gpio12). +It is possible to attach a usb socket directly to AR7240. You need to solder directly to SoC pins and provide two 15k pulldowns on every line. **D- is pin 73** and **D+ is pin 74**. USB power should come from somewhere else (e.g. an additional step-down 5V regulator connected to the main power source, LM2574 seems like a nice choice).

-It is possible to attach a usb socket directly to AR7240. You need to solder directly to SoC pins and provide two 15k pulldowns on every line. **D- is pin 73** and **D+ is pin 74**. USB power should come from somewhere else (e.g. an additional step-down 5V regulator connected to the main power source, LM2574 seems like a nice choice). +

-In 3.2.9  +**Also firmware for 741nd is working in 743nd**
-I change from +
-<code>+    ar71xx_add_device_usb();</code> +
-to  +
-<code>+    ath79_register_usb();</code>+
 +=== WR741 V1, V2 USB mod on trunk (Barrier Breaker) ===
 +Note: Modification for V4 is not needed. The files are already patched.
-=== For new trunks r3+ the patch is changed ===+1. Setup you Buildroot (download the source, install the packages, make defconfig, make prereq, make menuconfig
-for manual patching **Kconfig** +2. Select the needed packages - kmod-usb-storage block-mount kmod-fs-ext4 e2fsprogs (you can add other kmod-fs modules for other file systems like NTFS and fat)
-cd into **/trunk/build_dir/linux-ar71xx_generic/linux-3.3.8/arch/mips/ath79** +
-and edit the wr741nd code.  +
-You may also edit for wr743nd +
-<code> +
-config ATH79_MACH_TL_WR741ND +

- select ATH79_DEV_LEDS_GPIO +
- select ATH79_DEV_M25P80 +
-</code>+
-for **mach-tl-wr741nd.c** change folowing line +3. Run make (build the source).
-<code> +
- ath79_register_usb(); +
-</code> +
-if those files are not available build the toolchain first +
-<code>make prereq && make tools/install && make toolchain/install</code>+
-**Also firmware for 741nd is working in 743nd**+4. Edit the following file (MUST BUILD FIRST!!!):

-==== TL-WR741ND v1.9 ==== +After: <code>#include "dev-gpio-buttons.h"</code>
-Because of a change in the flash chip to the EON EN25F32 flash chip on the hardware version v1.9. A new patch to support this flash chip was created. You can either compile openwrt trunk or add this patch: +
-https://dev.openwrt.org/changeset/23058+Add: <code>#include "dev-usb.h"</code>
-To your openwrt 10.03 source files and compile openwrt.+After: <code>ath79_register_eth(0);</code>
-==== TL-WR741ND v2.X ==== +Add: <code>ath79_register_usb();</code> 
-Device works with Backfire 10.03.01 and latest [[http://downloads.openwrt.org/snapshots/trunk/ar71xx/openwrt-ar71xx-generic-tl-wr741nd-v2-squashfs-factory.bin|trunk image]] and also with[[http://www.gargoyle-router.com/downloads/images/ar71xx/gargoyle_1.4.0-ar71xx-tl-wr741nd-v1-squashfs-sysupgrade.bin|**Gargoyle** build]], no flaws discovered.+

-=== Power characteristics === +Add: <code>select ATH79_DEV_USB</code>
-  * The router contains an MP1482DS step down voltage regulator, with the voltage range from 4.75V to 18V. This are absolute maximum ratings, other components might not be able to widstand such a range. 5V to 15V should be a safe range.+
-==== TL-WR741ND v4.x ====+After:

 +      select ATH79_DEV_M25P80 
 +</code>
-Version 4.x has changed to use the AR9331 SoC, and is supported by the trunk version.\\  +5. Make (compile) once again. Now usb support should work.
-Probably the hardware of all v4.x versions is identical.+
-After installation of r31249 + LuCI, 604KB flash are free for additional packages.
