Hardware
--------
- SoC: MediaTek MT7621AT with 128 MiB RAM and 32 MiB Flash
- Wi-Fi: MediaTek MT7603 (b/g/n, 2x2) and MediaTek MT7615 (ac, 4x4)
- Bluetooth: CSR8811 (internal USB, install kmod-bluetooth)
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt".
2. Update the bootloader environment.
$ fw_setenv devmode TRUE
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
3. Transfer the OpenWrt sysupgrade image to the device using SCP.
4. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
5. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
6. 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
7. Reboot the device. It should boot into OpenWrt.
