Mikrotik Routerboard 433

Esta board vem pré-instalada com “MikroTik RouterOS v3, Level4 license”.

Para passar a correr OpenWRT, é necessário construir um kernel específico para o “Atheros AR7130”.

O kernel é carregado por tftp, e é necessário um dhcpd para configurar o acesso ao tftp pela board e indicar o kernel.

uma dhcpd.conf possível é:

subnet netmask {
    interface eth0;
    default-lease-time 6000;
    max-lease-time 7200;
    option subnet-mask;
    option time-offset -3600;
host routerboard {
    hardware ethernet 00:0c:42:FF:FF:FF;
    filename "openwrt-ar71xx-vmlinux-initramfs.elf";
    default-lease-time 7200;

Com o dhcpd configurado e o kernel certo acessível por tftp, escolhemos como “boot device” a ethernet. Boot inicial (consola 115200-8N1):

RouterBOOT booter 2.16
