ramips: add support for Linksys EA7500 v2
The Linksys EA7500 v2 is advertised as AC1900, but its internal
hardware is AC2600 capable.
Hardware
--------
SoC: Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM: 256M (Nanya NT5CC128M16IP-DI)
FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI)
ETH: 5x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
- 2.4GHz: 1x MT7615N (4x4:4)
- 5GHz: 1x MT7615N (4x4:4)
- 4 antennas: 3 external detachable antennas and 1 internal
USB:
- 1x USB 3.0
- 1x USB 2.0
BTN:
- 1x Reset button
- 1x WPS button
LEDS:
- 1x White led (Power)
- 6x Green leds (link lan1-lan4, link wan, wps)
- 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable)
Everything works correctly.
Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).
After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

ramips: add support for D-Link DIR-853 A3
Specifications:
* SoC: MT7621AT
* RAM: 256MB
* Flash: 128MB NAND flash
* WiFi: MT7615DN (2.4GHz+5Ghz) with DBDC
* LAN: 5x1000M
* Firmware layout is Uboot with extra 96 bytes in header
* Base PCB is DIR-1360 REV1.0
* LEDs Power Blue+Orange,Wan Blue+Orange,WPS Blue,"2.4G"Blue, "5G" Blue,
USB Blue
* Buttons Reset,WPS, Wifi
MAC addresses on OEM firmware:
lan factory 0xe000 f4:*:*:a8:*:65 (label)
wan factory 0xe006 f4:*:*:a8:*:68
2.4 GHz [not on flash] f6:*:*:c8:*:66
5.0 GHz factory 0x4 f4:*:*:a8:*:66
The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:
5g 2.4g increment
f4:XX:XX:a8:XX:66 f6:XX:XX:c8:XX:66 +0x20
x0:xx:xx:68:xx:xx x2:xx:xx:48:xx:xx -0x20
x4:xx:xx:6a:xx:xx x6:xx:xx:4a:xx:xx -0x20
Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.
Flashing instruction:
The Dlink "Emergency Room" cannot be accessed through the reset
button on this device. You can either use console or use the
encrypted factory image availble in the openwrt forum.
Once the encrypted image is flashed throuh the stock Dlink web
interface, the sysupgrade images can be used.
Header pins needs to be soldered near the WPS and Wifi buttons.
The layout for the pins is (VCC,RX,TX,GND). No need to connect the VCC.
the settings are:
Bps/Par/Bits : 57600 8N1
Hardware Flow Control : No
Software Flow Control : No
Connect your client computer to LAN1 of the device
Set your client IP address manually to 192.168.0.101 / 255.255.255.0.
Call the recovery page or tftp for the device at http://192.168.0.1
Use the provided emergency web GUI to upload and flash a new firmware to
the device
At the time of adding support the wireless config needs to be set up by
editing the wireless config file:
* Setting the country code is mandatory, otherwise the router loses
connectivity at the next reboot. This is mandatory and can be done
from luci. After setting the country code the router boots correctly.
A reset with the reset button will fix the issue and the user has to
reconfigure.
* This is minor since the 5g interface does not come up online although
it is not set as disabled. 2 options here:
1- Either run the "wifi" command. Can be added from LUCI in system -
startup - local startup and just add wifi above "exit 0".
2- Or add the serialize option in the wireless config file as shown
below. This one would work and bring both interfaces automatically
at every boot:
config wifi-device 'radio0'
option serialize '1'
config wifi-device 'radio1'
option serialize '1'

------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web

Otherwise the router will try to boot 3 times and then will

Simply wait and try to reach the router through the web interface

After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.

ramips: add support for RAISECOM MSG1500 X.00
RAISECOM MSG1500 X.00 is a 2.4/5 GHz band 11ac (Wi-Fi 5) router.
Apart from the general model, there are two ISP customized models:
China Mobile and China Telecom.
Specifications:
- SoC: Mediatek MT7621AT
- RAM: 256MiB DDR3
- Flash: 128MiB NAND
- Ethernet: 5 * 10/100/1000Mbps: 4 * LAN + 1 * WAN
- Switch: MediaTek MT7530 (SoC)
- WLAN: 1 * MT7615DN Dual-Band 2.4GHz 2T2R (400Mbps) 5GHz 2T2R (867Mbps)
- USB: 1 * USB 2.0 port
- Button: 1 * RESET button, 1 * WPS button, 1 * WIFI button
- LED: blue color: POWER, WAN, WPS, 2.4G, 5G, LAN1, LAN2, LAN3, LAN4, USB
- UART: 1 * serial port header (4-pin)
- Power: DC 12V, 1A
- Switch: 1 * POWER switch
MAC addresses as verified by vendor firmware:
use address source
LAN C8:XX:XX:3A:XX:E7 Config "protest_lan_mac" ascii (label)
WAN C8:XX:XX:3A:XX:EA Config "protest_wan_mac" ascii
5G C8:XX:XX:3A:XX:E8 Factory "0x4" hex
2.4G CA:XX:XX:4A:XX:E8 [not on flash]
The increment of the 4th byte for the 2.4g address appears to vary.
Reported cases:
5g 2.4g increment
C8:XX:XX:90:XX:C3 CA:XX:XX:C0:XX:C3 0x30
C8:XX:XX:3A:XX:08 CA:XX:XX:4A:XX:08 0x10
C8:XX:XX:3A:XX:E8 CA:XX:XX:4A:XX:E8 0x10
Since increment is inconsistent and there is no obvious pattern
in swapping bytes, and the 2.4g address has local bit set anyway,
it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.
Notes:
1. The vendor firmware allows you to connect to the router by telnet.
(known version 1.0.0 can open telnet.)
There is no official binary firmware available.
Backup the important partitions data:
"Bootloader", "Config", "Factory", and "firmware".
Note that with the vendor firmware the memory is detected only 128MiB
and the last 512KiB in NAND flash is not used.
2. The POWER LED is default on after press POWER switch.
The WAN and LAN1 - 4 LEDs are wired to ethernet switch.
The WPS LED is controlled by MT7615DN's GPIO.
Currently there is no proper way to configure it.
3. At the time of adding support the wireless config needs to be set up
by editing the wireless config file:
* Setting the country code is mandatory, otherwise the router loses
connectivity at the next reboot. This is mandatory and can be done
from luci. After setting the country code the router boots correctly.
A reset with the reset button will fix the issue and the user has to
reconfigure.
* This is minor since the 5g interface does not come up online although
it is not set as disabled. 2 options here:
1- Either run the "wifi" command. Can be added from LuCI in system -
startup - local startup and just add wifi above "exit 0".
2- Or add the serialize option in the wireless config file as shown
below. This one would work and bring both interfaces automatically
at every boot:
config wifi-device 'radio0'
option serialize '1'
config wifi-device 'radio1'
option serialize '1'
Flash instructions using initramfs image:
1. Press POWER switch to power down if the router is running.
2. Connect PC to one of LAN ports, and set
static IP address to "10.10.10.2", netmask to "255.255.255.0",
and gateway to "10.10.10.1" manually on the PC.
3. Push and hold the WIFI button, and then power up the router.
After about 10s (or you can call the recovery page, see "4" below)
you can release the WIFI button.
There is no clear indication when the router
is entering or has entered into "RAISECOM Router Recovery Mode".
4. Call the recovery page for the router at "http://10.10.10.1".
Keep an eye on the "WARNING!! tip" of the recovery page.
Click "Choose File" to select initramfs image, then click "Upload".
5. If image is uploaded successfully, you will see the page display
"Device is upgrading the firmware... %".
Keep an eye on the "WARNING!! tip" of the recovery page.
When the page display "Upgrade Successfully",
you can set IP address as "automatically obtain".
6. After the rebooting (PC should automatically obtain an IP address),
open the SSH connection, then download the sysupgrade image
to the router and perform sysupgrade with it.
Flash back to vendor firmware:
See "Flash instructions 1 - 5" above.
The only difference is that in step 4
you should select the vendor firmware which you backup.

ramips: add support for Linksys EA7500 v2
The Linksys EA7500 v2 is advertised as AC1900, but its internal
hardware is AC2600 capable.
Hardware
--------
SoC: Mediatek MT7621AT (880 MHz, 2 cores 4 threads)
RAM: 256M (Nanya NT5CC128M16IP-DI)
FLASH: 128MB NAND (Macronix MX30LF1G18AC-TI)
ETH: 5x 10/100/1000 Mbps Ethernet (MT7530)
WIFI:
- 2.4GHz: 1x MT7615N (4x4:4)
- 5GHz: 1x MT7615N (4x4:4)
- 4 antennas: 3 external detachable antennas and 1 internal
USB:
- 1x USB 3.0
- 1x USB 2.0
BTN:
- 1x Reset button
- 1x WPS button
LEDS:
- 1x White led (Power)
- 6x Green leds (link lan1-lan4, link wan, wps)
- 5x Orange leds (act lan1-lan4, act wan) (working but unmodifiable)
Everything works correctly.
Installation
------------
The “factory” openwrt image can be flashed directly from OEM stock
firmware. After the flash the router will reboot automatically.
However, due to the dual boot system, the first installation could fail
(if you want to know why, read the footnotes).
If the flash succeed and you can reach OpenWrt through the web
interface or ssh, you are done.
Otherwise the router will try to boot 3 times and then will
automatically boot the OEM firmware (don’t turn off the router.
Simply wait and try to reach the router through the web interface
every now and then, it will take few minutes).
After this, you should be back in the OEM firmware.
Now you have to flash the OEM Firmware over itself using the OEM web
interface (I tested it using the FW_EA7500v2_2.0.8.194281_prod.img
downloaded from the Linksys website).
When the router reboots flash the “factory” OpenWrt image and this
time it should work.
After the OpenWrt installation you have to use the sysupgrade image
for future updates.
Restore OEM Firmware
--------------------
After the OpenWrt flash, the OEM firmware is still stored in the
second partition thanks to the dual boot system.
You can switch from OpenWrt to OEM firmware and vice-versa failing
the boot 3 times in a row:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
If you want to completely remove OpenWrt from your router, switch to
the OEM firmware and then flash OEM firmware from the web interface
as a normal update.
This procedure will overwrite the OpenWrt partition.
Footnotes
---------
The Linksys EA7500-v2 has a dual boot system to avoid bricks.
This system works using 2 pair of partitions:
1) "kernel" and "rootfs"
2) "alt_kernel" and "alt_rootfs".
After 3 failed boot attempts, the bootloader tries to boot the other
pair of partitions and so on.
This system is managed by the bootloader, which writes a bootcount in
the s_env partition, and if successfully booted, the system add a
"zero-bootcount" after the previous value.
A system update performed from OEM firmware, writes the firmware on the
other pair of partitions and sets the bootloader to boot the new pair
of partitions editing the “boot_part” variable in the bootloader vars.
Effectively it's a quick and safe system to switch the selected boot
partition.
Another way to switch the boot partition is:
1) power on the router
2) wait 15 seconds
3) power off the router
4) repeat steps 1-2-3 twice more.
5) power on the router and you should be in the “other” firmware
In this OpenWrt port, this dual boot system is partially working
because the bootloader sets the right rootfs partition in the cmdline
but unfortunately OpenWrt for ramips platform overwrites the cmdline
so is not possible to detect the right rootfs partition.
Because all of this, I preferred to simply use the first pair of
partitions and set read-only the other pair.
However this solution is not optimal because is not possible to know
without opening the case which is the current booted partition.
Let’s take for example a router booting the OEM firmware from the first
pair of partitions. If we flash the OpenWrt image, it will be written
on the second pair. In this situation the router will bootloop 3 times
and then will automatically come back to the first pair of partitions
containg the OEM firmware.
In this situation, to flash OpenWrt correctly is necessary to switch
the booting partition, flashing again the OEM firmware over itself.
At this point the OEM firmware is on both pair of partitions but the
current booted pair is the second one.
Now, flashing the OpenWrt factory image will write the firmware on
the first pair and then will boot correctly.
If this limitation in the ramips platform about the cmdline will be
fixed, the dual boot system can also be implemented in OpenWrt with
almost no effort.
