- [x] Must be flashable from vendor firmware
- [x] Web interface
- [ ] TFTP (untested, but possible according to OpenWrt wiki)
- [ ] Other: <specify>
- [x] Must support upgrade mechanism
- [x] Must have working sysupgrade
- [x] Must keep/forget configuration (`sysupgrade [-n]`, `firstboot`)
- [x] Gluon profile name matches autoupdater image name
(`lua -e 'print(require("platform_info").get_image_name())'`)
- [x] Reset/WPS/... button must return device into config mode
- [x] Primary MAC address should match address on device label (or packaging)
(https://gluon.readthedocs.io/en/latest/dev/hardware.html#notes)
- When re-adding a device that was supported by an earlier version of Gluon, a
factory reset must be performed before checking the primary MAC address, as
the setting from the old version is not reset otherwise.
- Wired network
- [x] should support all network ports on the device
- [x] must have correct port assignment (WAN/LAN)
- On devices supplied via PoE, there is usually no explicit WAN/LAN labeling on the hardware.
The PoE input should be the WAN port in this case.
- Wireless network (if applicable)
- [x] Association with AP must be possible on all radios
- [x] Association with 802.11s mesh must work on all radios
- [x] AP+mesh mode must work in parallel on all radios
- LED mapping
- Power/system LED
- [x] Lit while the device is on
- [x] Should display config mode blink sequence
(https://gluon.readthedocs.io/en/latest/features/configmode.html)
- Radio LEDs
- [x] Should map to their respective radio
- [x] Should show activity
- Switch port LEDs
- [x] Should map to their respective port (or switch, if only one led present)
- [x] Should show link state and activity
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.
Specifications:
- SoC: MediaTek MT7621
- Flash: 16 MiB NOR SPI
- RAM: 128 MiB DDR3
- Ethernet: 3x 10/100/1000 Mbps (switched, 2xLAN + WAN)
- WIFI0: MT7603E 2.4GHz 802.11b/g/n
- WIFI1: MT7612E 5GHz 802.11ac
- Antennas: 4x external (2 per radio), non-detachable
- LEDs: Programmable "power" LED (two-coloured, yellow/blue)
Non-programmable "internet" LED (shows WAN activity)
- Buttons: Reset
Installation:
Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on".
Vendor firmware won't accept any serial input until "uart_en" is
set to "1".
Using the https://github.com/acecilia/OpenWRTInvasion exploit you
can gain access to shell to enable these options:
To enable uart keyboard actions - 'nvram set uart_en=1'
To make uboot delay boot work - 'nvram set boot_wait=on'
Set boot delay to 5 - 'nvram set bootdelay=5'
Then run 'nvram commit' to make the changes permanent.
Once in the shell (following the OpenWRTInvasion instructions) you
can then run the following to flash OpenWrt and then reboot:
'cd /tmp; curl https://downloads.openwrt.org/...-sysupgrade.bin
--output firmware.bin; mtd -e OS1 -r write firmware.bin OS1'
