Installing openwrt on a mikrotik routerboard code#
With the 18.06 merger of openwrt/LEDE and the addition of the Unsorted Block Images (UBI) code to the Mikrotik code base described here Introduce sysupgrade + 64MB/Large NAND sysupgrade images, this has become much simpler than previous versions of openwrt installation.Īfter loading the initramfs-lzma.elf image using netboot, connect to any of the LAN ports (ether2 through ether9) on the RB493G, login to LUCI (default at 192.168.1.1), and perform a 'Flash image' from System→Backup/Flash Firmware You need a working Netboot first, see above. etc/init.d/dnsmasq restart Permanent Installation Into NAND Flash Then restart dnsmasq to make the change effective (cross-check that you indeed have net-access afterwords): Note that you may need to set dns servers to get net-access while running the netbooted image. Press Enter and you are in the console of OpenWRT running from RAM and booted via DHCP/BOOTP/ TFTP. br-lan: port 2(eth1.1) entered forwarding state br-lan: port 1(eth0) entered forwarding state Please press Enter to activate this console. Initrd not found or empty - disabling initrd Press any key within 2 seconds to enter setup. If everything is setup correctly it should look like: If your DHCP/BOOTP/ TFTP netboot server is rfc951 BOOTP-capable, using the Reset button is a very easy way to force the RouterBoard to netboot right out of the package. The default boot protocol is BOOTP, not DHCP, so the RouterBoard will attempt a BOOTP netboot if the Reset button is held without performing the boot protocol change described in Option 1 ('p', then '2'). Note this method will use the boot protocol already set in Option 1 above. If the attempted ethernet netboot fails, it will then boot from flash (just like the 'boot from ethernet once' option chosen above in Option 1).
Once the RouterBoard beeps, there is no need to continue holding the Reset button (the beep indicates it is now performing a netboot or loading from flash) Use another (existing) OpenWrt router as the netboot server When using BOOTP as the boot protocol, be sure to disconnect from any other network devices (routers) since BOOTP has no provisions for Proxy DHCP or authoritative DHCP across multiple simultaneous BOOTP servers: there must be only one DHCP/BOOTP/ TFTP server running on the network. If you power up the RouterBoard and continue holding the reset button, it will automatically search for a BOOTP server: no need to change any of the RouterBoot settings from their default settings with this approach.

To enable rfc951 BOOTP in Tiny PXE, the option 'rfc951=1' must be set in the section of config.ini file of Tiny PXE.ĭownload the initramfs-lzma.elf file to your PC, enter it as the Boot file name in Tiny PXE, select your 192.168.88.X connection as the Option 54 DHCP server (be sure your PC is set to a static IP in the 192.168.88.2-192.168.88.254 range), and put Tiny PXE online.
Tiny PXE will directly respond to the BOOTP request of the RouterBoard. With rfc951 BOOTP, there is no need to enter the RouterBoot console and change the boot protocol from BOOTP to DHCP. This is possibly the easiest way to netboot a RB493G since Tiny PXE implements rfc951 BOOTP.

The freeware Tiny PXE project is a standalone portable Windows application that implements a DHCP server, BOOTP server, and TFTP server.
