Manual:RouterBOOT

RouterBOOT is responsible for starting RouterOS in RouterBOARD devices.

Main and Backup loaders

By default, the main loader is used, but RouterBOARD devices also have a secondary (backup) bootloader, which can be used in case the main doesn't work. It is possible to call the backup loader with a configuration setting in RouterOS:

system routerboard settings set force-backup-booter=yes

it is also possible to use the backup booter by turning on the device, with the RESET button pushed. Sometimes the RouterBOOT receives firmware upgrades (see Changelog). It is only possible to upgrade the main RouterBOOT, so in case of failure, you can use the backup booter to start the device and downgrade the main loader. For upgrade instructions, follow the separate instructions in Manual:Bootloader upgrade

RouterBOARD reset button

RouterBOOT reset button has three functions:

• Hold this button during boot time until LED light starts flashing, release the button to reset RouterOS configuration (total 5 seconds)
• Keep holding for 5 more seconds, LED turns solid, release now to turn on CAPs mode (total 10 seconds)
• Or Keep holding the button for 5 more seconds until until LED turns off, then release it to make the RouterBOARD look for Netinstall servers (total 15 seconds)

Note: If you hold the button before applying power, backup RouterBOOT will be used in addition to all the above actions. To do the above actions without loading the backup loader, push the button right after applying power to the device.

Configuration

For RouterBOARD devices that feature a serial console connector, it is possible to access the RouterBOOT loader configuration menu. The required cable is described in the Serial console manual. RouterBOARD serial port is configured to 115200bit/s, 8 data bits, 1 stop bit, no parity. We suggest to disable the hardware flow control.

This example shows the menu which is available in RouterBOOT 3.19:

Simple Upgrade

RouterBOOT can be upgraded from RouterOS by:

• Run command /system routerboard upgrade
• Reboot your router to apply the upgrade (/system reboot)]

Note: If you need to install a different version than included in your "routerboard.npk - Upload the latest RouterBOOT firmware to your router's FTP, the latest firmware is available on routerboard.com and then follow above steps.

Checking RouterBOOT version

This command shows the current RouterBOOT version of your device, and available upgrade which is either included in routerboard.npk package, or if you uploaded a FWF file corresponding to device model:

[admin@MikroTik] > system routerboard print 
       routerboard: yes
             model: "750"
     serial-number: "1FC201DD513B"
  current-firmware: "2.18"
  upgrade-firmware: "2.20"
[admin@MikroTik] > 

In this case you see, that there is a newer version of the Bootloader firmware available already inside your current RouterOS version.

Note: Downgrade is also possible by uploading *.FWF file with older version

Xmodem Method

If there is no IP connectivity with your RouterBOARD, you can also use the Serial Console XMODEM transfer to send the FWF file to the router, while connected via Serial Console. From the Bootloader menu it's possible to upgrade the firmware with this method. This method is the last resort, and should be used only if the first two methods are not available.
