This device has previously been supported by the image
for Xiaomi Mi Router 3G v2. Since this is not obvious, the
4A is marketed as a new major revision and it also seems to
have a different bootloader, this will be both more tidy and
more helpful for the users.
Apart from that, note that there also is a 100M version of
the device that uses mt7628 platform, so a specifically named
image will also prevent confusion in this area.
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'

Ubiquiti EdgeRouter 4 is 4 port Octeon Cavium 7130 powered router.
It has internal power supply and needs c13 power cord.
There are three 10/100/1000 Mbps RJ45/Copper ports and
one 1000 Mbps SFP port connected directly to a SoC.
SoC:
Octeon Cavium 7130 (Cavium 3)
Clocked at 1000Mhz
Memory:
1 GiB (SK hynix H5TQ4G63CFR-RDC × 2)
DDR3, clocked at 533 Mhz (1066Mhz effective)
Flash:
- mtd:
8 MiB (Macronix MX25L6408EMI-12G)
used for uboot/eeprom
- emmc:
4 GiB (SanDisk SDIN7DP2-4G)
used for kernel+rootfs
Leds: 1x for power status (white/blue, controllable)
and 4x for ethernet and sfp ports (no control over them)
Buttons: 1x Reset (from SOC)
Serial: 1x RJ45 port on front panel. 115200 baud, 8N1 (from SoC)
USB: 1x USB3.0 on front panel (from SoC)
MII: 1x QSGMII from SoC is used
PHY: 1x Vitesse VSC8504 of which 4x ports is used
All physical port numbers are properly mapped inside OS and
named by lanX instead of ethX.
There is also special purpose four(4) loopX ports available.
That loopX ports are currently hardcoded by linux kernel
and exact use case of them is currently unknown. We leave them
to the linux kernel and octeon board defaults.
All four (4) physical ports are connected to the same QSGMII.
vsc8504 is used for phys and only 4, 5, 6 and 7 phys are used.
Phy mapping:
- Phy5 is connected to physical eth0 port
- Phy6 is connected to physical eth1 port
- Phy7 is connected to physical eth2 port
- Phy4 is connected to physical eth3 port
Why this device needs external dts:
- faster boot time since need to initialize less device tree nodes.
- to add actual indication with LED about boot/failure/upgrade.
i.e. user could know when to enter failsafe mode or if upgrade is done
- reset button support so user can reset their device in case off failure
- sfp port indication in dmesg with information about sfp module
it also indicates when module inserted or removed
Octeon quirks:
- There is no port status available before it interface brought up
- SFP port can not be tied to actual phy due to octeon-ethernet state
and currently we can only get reports a about SFP state in dmesg
How to flash the firmware:
- copy openwrt-octeon-ubnt_edgerouter-4-initramfs-kernel.bin and
openwrt-octeon-ubnt_edgerouter-4-squashfs-sysupgrade.tar to
USB flash drive that is formatted to vfat/fat32
- connect USB flash drive to edgerouter 4 front USB port
- connect serial cable using front RJ45 port (115200 baud, 8N1)
- connect power to cable to edgerouter 4
- connect terminal to the console to see uboot boot process
- interrupt boot by pressing button(s) on your keyboard to log in to the uboot
- detect usb connected flash drives by typing to the console:
usb start
- after drive is detected load initramfs+kernel to the memory by typing:
fatload usb 0:1 0x20000000 openwrt-octeon-ubnt_edgerouter-4-initramfs-kernel.bin
- after initramfs+kernel is loaded to the memory load it by typing:
bootoctlinux 0 numcores=4 endbootargs mem=0
- boot process should finish and you will be greeted with console after pressing enter
- create directory to mount usb flash drive to by typing:
mkdir /tmp/sda
- mount flash drive to that directory by typing:
mount /dev/sda1 /tmp/sda
- flash firmware to router internal storage by typing:
sysupgrade /tmp/sda/openwrt-octeon-ubnt_edgerouter-4-squashfs-sysupgrade.tar
- device will reboot and after it gets up you will have edgerouter 4 running openwrt

In 4.14 the delays were not cleared, so setting "rgmii" as phy-mode
did not affect delays set by the bootloader. With 5.4 kernel the
situation changed and the ethernet interface stopped working.
"rgmii" requires rx and tx delays depending on the hardware circuit
and wiring. The mac or the phy can add these delays.
- "rgmii": delays are controlled by the mac
- "rgmii-id": delays are controlled by the phy
More Information in Linux Kernel Tree:
Documentation/devicetree/bindings/net/ethernet-controller.yaml
"rgmii" should be the preferred mode, which allows the mac layer to
turn off the dealys completely if they are not needed. However, the
delays are not set correctly, which causes the ethernet interface
to be broken. Just taking the ethernetpart from the litebeam ac gen2
will fix the issue.

In kernel commit adf82accc5f5 ("netfilter: x_tables: merge ip and

and IP6_NF_TARGET_MASQUERADE have been demoted to simple backwards-
compat options for NETFILTER_XT_TARGET_MASQUERADE.
In netfilter.mk, this has already been updated in OpenWrt commit
d1592306cc ("netfilter.mk: use CONFIG_NETFILTER_XT_TARGET_MASQUERADE"),
having us use the new config symbol.
However, enabling IP_NF_NAT or IP6_NF_NAT still makes the relevant
legacy options selectable, so we need to disable them in generic
config (and forget about them afterwards).
Since CONFIG_IP_NF_TARGET_MASQUERADE is already present there, this
just adds the missing CONFIG_IP6_NF_TARGET_MASQUERADE.
