FlashingEdit

First setup a TFTP server which is serving the firmware file. (Only flash "factory-to-"ddwrt/openwrt files)

Then we have to setup the network settings. Type the following things into the bootloader prompt. Replace ROUTERIP and SERVERIP with the right IPs.

setenv ipaddr ROUTERIP

setenv serverip SERVERIP

Now we have to load the firmware into the memory!. Replace FACTORY-TO-OPENWRT/DDWRT.bin with the right filename of the image!

ar7240> tftpboot 0x80000000 FACTORY-TO-OPENWRT/DDWRT.bin

You will read something like that. The size is very important. Note it. It can differ to the example.


Bytes transferred = 3932160 (3c0000 hex)

The last steps are erasing the flash and writing the new image to the right address. Replace 3c0000 with the address you noted before.

ar7240> erase 0x9f020000 +0x3c0000

ar7240> cp.b 0x80000000 0x9f020000 0x3c0000

ar7240> bootm 0x9f020000
