Buenas noches gracias por tu respuesta, debo aclarar que aunque el dispositivo aun no salga oficialmente soportado , puede funcionar el firmware, sobre todo en las versiones trunk y mas aun compilandolo uno mismo , dejo una guia sacada de una pagina que en estos momentos esta caida , doy las gracias ya que me ayudo mucho, espero que le sirva a alguien mas aqui el enlace ;
http://cirandas.net/brauliobo/blog/install-openwrt-on-mikrotik-sxt-lite-5 , cabe aclarar que es para el mikrotik sxt 5 , pero a mi me funciono para el sxt lite 2 , dejo el contenido de la pagina del proceso hecho con ubuntu valido en 16.04....
Proprietary stuff, what a bad choice! RouterOS has many features and SXT has pretty powerful hardware, but with level 3 licence you can't even work as a AP! Shame on you Mikrotik!
Start by installing some tools on your machine to setup a TFTP and DHCP server:
sudo apt-get install isc-dhcp-server atftpd wireshark
Write to /etc/default/atftpd
USE_INETD=false
OPTIONS="--bind-address 192.168.1.3 --tftpd-timeout 300 --retry-timeout 5 --mcast-port 1758 --mcast-addr 239.239.239.0-255 --mcast-ttl 1 --maxthread 100 --verbose=5 /srv/tftp"
And to /etc/dhcp/dhcpd.conf
authoritative;
allow booting;
allow bootp;
one-lease-per-client true;
## any host
subnet 192.168.1.0 netmask 255.255.255.0 {
filename "openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf";
next-server 192.168.1.3;
range dynamic-bootp 192.168.1.10 192.168.1.100;
}
## host specific
#subnet 192.168.1.0 netmask 255.255.255.0 {
# option routers 192.168.1.254;
# option subnet-mask 255.255.255.0;
# option broadcast-address 192.168.1.255;
# ignore client-updates;
#}
#group {
# host routerboard {
# hardware ethernet 4C:5E:0C:7B:6D:98;
# next-server 192.168.1.3;
# fixed-address 192.168.1.99;
# filename "openwrt-ar71xx-mikrotik-vmlinux-initramfs.elf";
# }
#}
Then
cd /srv/tftp; sudo wget
http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/mikrotik/openwrt-ar71xx-mikrotik-vmlinux-initramfs.elfsudo chmod -R 777 /srv
sudo service network-manager stop
sudo ifconfig eth0 192.168.1.3
sudo service atftpd restart
sudo service isc-dhcp-server restart
The manual is at
http://i.mt.lv/routerboard/files/SXTug.pdf. There you have a Button Index where you can see that if you hold the Reset button for more than 20 seconds (10 seconds after blinking stops) then Etherboot will be triggered.
Do this while watching Wireshark and /var/log/syslog
If things has gone correctly, you should be able to access the Luci web interface at
http://192.168.1.1
Now you'll need a local webserver for wget2nand to download the kernel and the rootfs:
sudo apt-get install apache2
cd /var/www/html && sudo wget
http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/mikrotik/openwrt-ar71xx-mikrotik-vmlinux-lzma.elfcd /var/www/html && sudo wget
http://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/mikrotik/openwrt-ar71xx-mikrotik-DefaultNoWifi-rootfs.tar.gzcd /var/www/html && sudo ln -sf openwrt-ar71xx-mikrotik-DefaultNoWifi-rootfs.tar.gz openwrt-ar71xx-mikrotik-rootfs.tar.gz
Now flash!
telnet 192.168.1.1
wget2nand 192.168.1.3
If you want to flash multiple devices, setup one with the packages (I've installed rsync ppp-mod-pptp luci-app-qos) and configuration you want and package a new rootfs (replace IP of the template device):
mkdir -p rootfs/{dev,proc,sys}
rsync -avP --exclude 'dev' --exclude 'proc' --exclude 'sys' root@10.10.20.14:/ rootfs
tar -C rootfs -zcvf openwrt-ar71xx-mikrotik-rootfs.tar.gz .
