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.

Installation:
Update using ASUS Firmware Restoration Tool:
1. Download the ASUS Firmware Restoration Tool but don't open it yet
2. Unplug your computer from the router
3. Put the router into Rescue Mode by: turning the power off, using a pin
to press and hold the reset button, then turning the router back on while
keeping the reset button pressed for ~5 secs until the power LED starts
flashing slowly (which indicates the router has entered Rescue Mode)
4. Important (if you don't do this next step the Asus Firmware
Restoration Tool will wrongly assume that the router is not in Rescue Mode
and will refuse to flash it): go to the Windows Control Panel and
temporarily disable ALL other network adapters except the one you will use
to connect your computer to the router
5. For the single adapter you left enabled, temporarily give it the
static IP 192.168.1.10 and the subnet mask 255.255.255.0
6. Connect a LAN cable between your computer (make sure to use the
Ethernet port of the adapter you've just set up) and port 1 of the router
(not the router's WAN port)
7. Rename sysupgrade.bin to factory.trx
8. Open the Asus Firmware Restoration Tool, locate factory.trx and click
upload (if Windows shows a compatibility prompt, confirm that the tool worked fine)
9. Flashing and reboot is finished when the power LED stops blinking and
stays on

This commit removes the target-specific diag.sh script. This way, the
generic one is used for the target, which uses DT-aliases to specify the
LEDs used.
Though generic diag.sh allows to use different LEDs to indicate different
states, this patch just moves the old assignment and does not try to
"improve" the assignment by using additional colors.
However, individual proposals to do so are welcome.
For the few cases where status_led2 was used in old diag.sh, only the
primary LED was migrated.

The id parameter in __rb_get_wlan_data() was incorrectly used on the
assumption that id "0" would always be tied to ath9k with RLE encoding
and positive id (in fact, only id "1" was valid) would always be tied to
("external") ath10k with LZO encoding.
Newer hardware revisions of supported devices prove this assumption to
be invalid, with ath9k caldata being now wrapped in MAGIC_ERD and LZO
compressed, so disable this check to allow newer hardware to correctly
decode caldata for ath9k. Since ath10k caldata is no longer pulled from
this implementation, this commit also disables the publication in sysfs
to avoid wasting memory.
Note: this patch assumes that ath9k caldata is never stored with the new
"LZOR" encoding scheme found on some ath10k devices.

1. Get the OpenWrt initramfs image. Rename it to ipq40xx.ari and put it
into the TFTP server root directory. Configure the TFTP server to
be reachable at 192.168.1.75/24. Connect the machine running the TFTP
server to the ethernet port of the access point.
2. Connect to the serial console. Interrupt autobooting by pressing
Enter when prompted.
3. Configure the bootargs and bootcmd for OpenWrt.
$ setenv bootargs_openwrt "setenv bootargs console=ttyMSM1,9600n8"
$ setenv nandboot_openwrt "run bootargs_openwrt; ubi part aos1;
ubi read 0x85000000 kernel; bootm 0x85000000"
$ setenv ramboot_openwrt "run bootargs_openwrt;
setenv ipaddr 192.168.1.105; setenv serverip 192.168.1.75;
netget; set fdt_high 0x87000000; bootm"
$ setenv bootcmd "run nandboot_openwrt"
$ saveenv
4. Load OpenWrt into RAM:
$ run ramboot_openwrt
5. After OpenWrt booted, transfer the OpenWrt sysupgrade image to the
/tmp folder on the device.
6. Flash OpenWrt:
Make sure you use the mtd partition with the label "ubi" here!
$ ubidetach -p /dev/mtd1
$ ubiformat /dev/mtd1
$ sysupgrade -n /tmp/openwrt-sysupgrade.bin
