Hardware
--------
MediaTek MT7621AT
16M SPI-NOR Macronix MX25L12835FMI
Microchip PD69104B1 4-Channel PoE-PSE controller
TI TPS2373 PoE-PD controller
PoE-Controller
--------------
By default, the PoE outputs do not work with OpenWrt. To make them output
power, install the "poemgr" package from the packages feed.
This package can control the PD69104B1 PSE controller.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt" via SSH.
2. Add the uboot-envtools configuration file /etc/fw_env.config with the
following content
$ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config
3. Update the bootloader environment.
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
4. Transfer the OpenWrt sysupgrade image to the device using SCP.
5. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
6. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
7. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
8. Reboot the device. It should boot into OpenWrt.
Restore to UniFi
----------------
To restore the vendor firmware, follow the Ubiquiti UniFi TFTP
recovery guide for access points. The process is the same for
the Flex switch.
