AR9341 Router TTL Line Brush Machine

Recently, I have a batch of OEM PoE routers that do not have a USB interface. It is just used to study the TTL flash machine.

Then connect the USB to TTL. Note here that some boards will be incompatible with garbled characters. You can try to change the baud rate. If not, just change a USB to TTL board.

The computer uses SecureCRT, serial port connection, there is no character on the connection, then power on the router, the screen starts to display UBOOT, press any key to interrupt, some press TPL interrupt or ctrl + c interrupt, I first flash breed

These software will be provided below to download, understand the command of FLASH before brushing

16M FLASH: flash address from 0x000000 ~ 0x0FFFFFF
ttl access flash address from 0x9F000000 ~ 0x9F0FFFFFF


The network cable is connected to the router lan port, the computer configuration is set to 192.168.0.2, the mask is 255.255.255.0, and the gateway is 192.168.0.1

Open tftp in my software package, select the network card connected to the router's network cable, it will normally display the IP 192.168.0.2, click "Show Dir" contains a firmware of breed-ar9341.bin, first flash him, execute the following command

setenv ipaddr 192.168.0.1

setenv serverip 192.168.0.2

tftp 0x80000000 breed-ar9341.bin

When done appears, it means that the brushing is successful, and then execute

erase 0x9f000000 + 0x20000

cp.b 0x80000000 0x9f000000 0x20000

When done appears, flashing in is successful. Unplug the router and plug it in again. SecureCRT displays the Breed boot and press any key terminal. At the same time, you can see that the default lan port address is 192.168.1.1

Connect the computer browser to 192.168.1.1, then you can directly use the Breed Web


Enter 192.168.0.1 in the address bar of the browser and select the firmware upgrade. Here you should save the original firmware under backup. You can configure openwrt after the flashing is completed.
