Flashing From The Stock Firmware

Aerohive routers come with a super locked down operating system on them. They're optimized for management via something called the Hive Manager, which is a cloud platform owned by Aerohive. This obviously won't do!

In order to flash OpenWrt, we will need to interrupt the boot-up process using a serial cable and a program called minicom. We will then load OpenWrt directly into RAM, and boot from memory. After booting a temporary copy of OpenWrt in this way, we can run a sysupgrade within OpenWrt to flash OpenWrt onto the hard-drive. This is not as hard as it sounds. Before proceeding, you will want to obtain a console cable, and download minicom.

Interrupt The Boot Process

  1. Connect your laptop to the Aerohive with a console cable
  2. launch `minicom` in a terminal
  3. Connect the Aerohive to power, and quickly press any key to interrupt the boot process
  4. You should see a prompt starting with

Use Tftpboot To Load OpenWrt Into Memory

There are a couple steps missing from the commit message. Namely, you should assign your 'laptop' a static IP address, and connect it to the Aerohive with an ethernet cable. If you don't know the name of your ethernet interface, run ip link.

# ip addr add 192.168.1.101/24 dev eth0
# systemctl start tftpd

Back in the console of the Aerohive (minicom,) first set the necessary environment variables, then use tftpboot to load the OpenWrt firmware directly into working memory.

=> setenv serverip 192.168.1.101                                                                                                                                                                                    
=> setenv ipaddr 192.168.1.1
=> tftpboot 0x1000000 192.168.1.101:openwrt-mpc85xx-p1020-aerohive_hiveap-330-initramfs-kernel.bin                                                                                                                  
=> tftpboot 0x6000000 192.168.1.101:openwrt-mpc85xx-p1020-aerohive_hiveap-330-squashfs-fdt.bin                                                                                                                      
=> bootm 0x1000000 - 0x6000000

You should be prompted to press ENTER eventually, and see the familiar OpenWrt splash screen.
