Vendor: Qualcomm Atheros
Bootloader: RouterBoot
System-On-Chip: AR7241 (MIPS)
CPU/Speed 400 MHz
Flash-Chip: Samsung 313 NAND
Flash size: 64 MiB
RAM: 32 MiB
Network: Atheros AG71xx
Switch: Atheros AR7240/AR9330 (passive PoE capable)
USB: Yes 1 x 2.0

Installation

Similiar to the routerboard 750.

  1. Prepare an OpenWRT Ramdisk Image (Target: AR7XX, Subtarget: Mikrotik NAND Flash) or use this
  2. Configure a TFTP and DHCP Server. For informations how to do this see Wolf's Tech Blog.
  3. Connect yourself via cable into Port 1 and start your DHCP/TFTP servers.
  4. Boot the Routerboard into TFTP-Mode by pressing the RES button for several seconds until ACT led is not blinking anymore.
  5. Plug a network cable into port 3 and flash openwrt into the flash memory:
