-Send ''​openwrt-lantiq-arv7510pw_ram-u-boot.asc''​ as raw ascii to the router. U-Boot should start. Press any key to stop autoboot. At this point you can make a backup of the original firmware using ''​md.l 0xb0000000 0x1000000''​ and logging the output (takes roughly 2 hours). The flash can be erased by issuing first ''​protect off all''​ and then ''​erase all''​. Use first ''​setenv ipaddr 192.168.1.1'',​ ''​setenv serverip 192.168.1.2''​ and ''​setenv ethaddr xx:​xx:​xx:​xx:​xx:​xx''​ (ethernet address can be found from the sticker on top of the switch ports) to configure the network, and then ''​tftp 0x80700000 openwrt-lantiq-arv7510pw_nor-u-boot.img''​ to transfer the actual U-Boot image to memory. ​Write it to flash using ''​cp.b 0x80700000 0xb0000000 ${filesize}''​.

Caution!! do not use ''​erase all''​ as mentioned here before ​it will kill the calibration data belonging to the wireless chip resulting in a kernel panic at first boot of OpenWRT. After erasing write the new bootloader ​to flash using ''​cp.b 0x80700000 0xb0000000 ${filesize}''​. Power off the router and remove the jumper caps from UART boot pins.
