Subject: [PATCH] ramips-mt7621: add support for Ubiquiti UniFi 6 Lite (#2310)
Hardware
--------
MediaTek MT7621AT
256M DDR3
32M SPI-NOR
MediaTek MT7603 2T2R 802.11n 2.4GHz
MediaTek MT7915 2T2R 802.11ax 5GHz
Not Working
-----------
- Bluetooth (connected to UART3)
UART
----
UART is located in the lower left corner of the board. Pinout is
0 - 3V3 (don't connect)
1 - RX
2 - TX
3 - GND
Console is 115200 8N1.
Boot
----
1. Connect to the serial console and connect power.
2. Double-press ESC when prompted
3. Set the fdt address
$ fdt addr $(fdtcontroladdr)
4. Remove the signature node from the control FDT
$ fdt rm /signature
5. Transfer and boot the OpenWrt initramfs image to the device.
Make sure to name the file C0A80114.img and have it reachable at
192.168.1.1/24
$ tftpboot; bootm
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.
