Flashin OpenWRT on ZBT APG621

Introduction

  • The ZBT APG621 is an outdoor 5G single radio unit.
  • It comes standard with an OEM version of OpenWRT
  • We like the hardware because it is
    • Cost effective
    • Runs OpenWRT (Which means we can use it with MESHdesk and APdesk)
    • Easy to flash
  • There is no standard release of OpenWRT for this device but the Atheros DB120 reference board firmware seems to work well enough for us.

Instructiions

  • We assume that you have some form of the DB120 OpenWRT firmware.
  • The device has a very handy bootloader called BREED.
  • To get the bootloader in flash mode you can do the following.
    • Connect the device to a computer which is on the 192.168.1.x sub-net. (e.g. give your computer an IP of 192.168.1.10)
    • Run a continuous ping to 192.168.1.1.
    • Before applying power, press the reset button and keep it in while powering up the device.
    • The device should start answering pings after ~15seconds.
    • Now you can release the reset button.
