This commit removes the padded zeros in the date formatting.
The padded zeros from the date command causes the numbers
to be interpreted as an octal number by printf. Months, days,
and years with the number 08 or 09 raise an error in printf as an
"invalid octal number" and get interpreted as a zero.

The DRA-1360 rev A is a wall-plug AC1300 repeater.
Hardware is identical (same FCC ID, black case instead of white)
to D-Link DAP-1620 rev B, which is already supported, but a
different model name, revision, and hardware ID are needed.
Thus, the bulk of the DAP-1620 device tree is extracted to a
common dtsi included by the two models' device trees.

I-O DATA WN-DEAX1800GR is a 2.4/5 GHz band 11ax (Wi-Fi 6) router, based
on MT7621A.
Specification:
- SoC : MediaTek MT7621A
- RAM : DDR3 256 MiB (Nanya NT5CC128M16JR-EK)
- Flash : RAW NAND 128 MiB (Winbond W29N01HVSINF)
- WLAN : 2.4/5 GHz (MediaTek MT7915)
- Ethernet : 5x 10/100/1000 Mbps
- Switch : MT7530 (SoC)
- LEDs/Keys : 6x/3x
- UART : through-hole on PCB (J2)
- assignment: 3.3V, GND, TX, RX from "1" marking
- settings : 115200n8
- Power : 12 VDC, 1 A
Flash instruction using initramfs-factory image:
1. Boot WN-DEAX1800GR normally
2. Access to "http://192.168.0.1/" and open firmware update page
("ファームウェア")
3. Select the OpenWrt initramfs-factory.bin image and click update
("更新") button to perform firmware update
4. On the initramfs image, perform sysupgrade with the
squashfs-sysupgrade.bin image
5. Wait ~120 seconds to complete flashing
Note:
- This device has 2x OS images on the flash storage. In this support,
the first one will be used.
Warning:
- Do not use "saveenv" command on U-Boot CLI.
This device has wrong u-boot-env data. The actual length of individual
env data installed to the device is 0x1000 (4 KiB), but installed
U-Boot requires 0x20000 (128 KiB). So U-Boot determines the data is
invalid. Then, if you perform saving environment data with saveenv on
U-Boot CLI, installed env data will be overwritten with too few
default values without individual values (SSID, password, MAC
addresses, etc...).
MAC addresses:
LAN : 50:41:B9:xx:xx:F4 (Config, ethaddr (text))
WAN : 50:41:B9:xx:xx:F6 (Config, wanaddr (text))
2.4 GHz: 50:41:B9:xx:xx:F4 (Config, rmac (text) / Factory, 0x4 (hex))

The TP-Link EAP613 v1 is a ceiling-mount 802.11ax access point. It can
be powered via PoE or a DC barrel connector (12V). Connecting to the
UART requires fine soldering and careful manipulation of any soldered
wires.
Device details:
* SoC: MT7621AT
* Flash: 16 MiB SPI NOR
* RAM: 256 MiB DDR3L
* Wi-Fi:
* MT7905DA + MT7975D: 2.4 GHz + 5 GHz (DBDC), 2x2:2
* Two stamped metal antennas (ANT1, ANT2)
* One PCB antenna (ANT3)
* One unpopulated antenna (ANT4)
* Ethernet:
* 1× 10/100/1000 Mbps port with PoE
* LEDs:
* Array of four blue LEDs with one control line
* Buttons:
* Reset
* Board test points:
* UART: next to CPU RF-shield and power circuits
* JTAG: under CPU RF-shield (untested)
* Watchdog: 3PEAK TPV706 (not implemented)
Althought three antennas are populated, the MT7905DA does not support
the additional Rx chain for background DFS detection (or Bluetooth)
according to commit 6cbcc34f50 ("ramips: disable unsupported
background radar detection").
MAC addresses:
* LAN: 48:22:54:xx:xx:a2 (device label)
* WLAN 2.4 GHz: 48:22:54:xx:xx:a2
* WLAN 5 GHz: 48:22:54:xx:xx:a3
The radio calibration blob stored in flash also contains valid MAC
addresses for both radio bands (OUI 00:0c:43).
Factory install:
1. Enable SSH on the device via web interface
2. Log in with SSH, and run `cliclientd stopcs`
3. Upload -factory.bin image via web interface. It may be necessary to
shorten the filename of the image to e.g. 'factory.bin'.
Recovery:
1. Open the device by unscrewing four screws from the backside
2. Carefully remove board from the housing
3. Connect to UART (3.3V):
* Find test points labelled "VCC", "GND", "UART_TX", "UART_RX"
* Solder wires to test points or connect otherwise. Be careful not
to damage the PCB e.g. by pulling on soldered wires.
* Open console with 115200n8 settings
4. Interrupt bootloader and use tftpboot to start an initramfs:
setenv ipaddr $DEVICE_IP
setenv serverip $SERVER_IP
tftpboot 84000000 openwrt-initramfs-kernel.bin
bootm
DO NOT use saveenv to store modified u-boot environment variables. The
environment is saved at flash offset 0x30000, which erases part of the
(secondary) bootloader.
The device uses two bootloader stages. The first stage will load the
second stage from a uImage stored at flash offset 0x10000. In case of
a damaged second stage, the first stage should allow uploading a new
image via y-modem (untested).

The MR600v2 does not find its rootfs if it is neither directly after the
kernel or aligned to an erase block boundary (64k).
This aligns the rootfs to 0x10000 allowing the device to boot again. Based
on investigation by forum user relghuar.

In kernel 5.15, the default erase sector size of the nor flash has
been switched from 4k to 64k. This may cause the configuration not
be preserved across upgrades. To avoid this issue, change the default

This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).
Installation using factory image
--------------------------------
Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.
1. Login to the router web interface (http://192.168.0.1/ by default) and
save running config to "conf.bin" file
2. Open configuration file in any TP-Link config editor (e.g.
https://jahed.github.io/tp-link-config-editor/)
3. Find "DeviceInfo" section and insert a new string "<Description
val="Modem Router`telnetd -p 1023 -l login`" />" according to the
following example:
<DeviceInfo>
...
<Description val="Modem Router`telnetd -p 1023 -l login`" />
...
</DeviceInfo>
4. Save configuration file and upload changed configuration using stock
firmware interface
5. Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6. Run "cat /proc/mtd | grep mtd7"
a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
then install stock firmware using web interface to toggle booted
firmware image from "os1" to "os0"
b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
then all is ok, go to the next step
7. Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
in this example)
8. Login using telnet to 192.168.0.1
9. Download OpenWrt factory.bin image from the tftp server:
cd /tmp
tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router

The ZyXEL WSM20 aka Multy M1 is a cheap mesh router system by ZyXEL
based on the MT7621 CPU.
Specifications
==============
SoC: MediaTek MT7621AT (880MHz)
RAM: 256MiB
Flash: 128MiB NAND
Wireless: 802.11ax (2x2 MT7915E DBDC)
Ethernet: 4x 10/100/1000 (MT7530)
Button: 1x WPS, 1x Reset, 1x LED On/Off
LED: 7 LEDs (3x white, 2x red, 2x green)
MAC address assignment
======================
The MAC address assignment follows stock: The label MAC address is the LAN
MAC address, the WAN address is read from flash.
The WiFi MAC addresses are set in userspace to label MAC + 1 and label MAC
+ 2.
Installation (web interface)
============================
The device is cloud-managed, but there is a hidden local firmware upgrade
page in the OEM web interface. The device has to be registered in the
cloud in order to be able to access this page.
The system has a dual firmware design, there is no way to tell which
firmware is currently booted. Therefore, an -initramfs version is flashed
first.
1. Log into the OEM web GUI
2. Access the hidden upgrade page by navigating to
https://192.168.212.1/gui/#/main/debug/firmwareupgrade
3. Upload the -initramfs-kernel.bin file and flash it
4. Wait for OpenWrt to boot and log in via SSH
5. Transfer the sysupgrade file via SCP
6. Run sysupgrade to install the image
7. Reboot and enjoy
NB: If the initramfs version was installed in RAS2, the sysupgrade script
sets the boot number to the first partition. A backup has to be performed
manually in case the OEM firwmare should be kept.
Installation (UART method)
==========================
The UART method is more difficult, as the boot loader does not have a
timeout set. A semi-working stock firmware is required to configure it:
1. Attach UART
2. Boot the stock firmware until the message about failsafe mode appears
3. Enter failsafe mode by pressing "f" and "Enter"
4. Type "mount_root"
5. Run "fw_setenv bootmenu_delay 3"
6. Reboot, U-Boot now presents a menu
7. The -initramfs-kernel.bin image can be flashed using the menu
8. Run the regular sysupgrade for a permanent installation
Changing the partition to boot is a bit cumbersome in U-Boot, as there is
no menu to select it. It can only be checked using mstc_bootnum. To change
it, issue the following commands in U-Boot:
nand read 1800000 53c0000 800
mw.b 1800004 1 1
nand erase 53c0000 800
nand write 1800000 53c0000 800
This selects FW1. Replace "mw.b 1800004 1 1" by "mw.b 1800004 2 1" to
change to the second slot.
Back to stock
=============
It is possible to flash back to stock, but a OEM firmware upgrade is
required. ZyXEL does not provide the link on its website, but the link
can be acquired from the OEM web GUI by analyzing the transferred JSON
objects.
It is then a matter of writing the firmware to Kernel2 and setting the
boot partition to FW2:
mtd write zyxel.bin Kernel2
echo -ne "\x02" | dd of=/dev/mtdblock7 count=1 bs=1 seek=4 conv=notrunc

0x000000fb0000-0x000001000000 : "Private"
```
The kernel partition will be replaced with the OpenWrt image, the other
partitions are left untouched.
"Config2" seems to be the config storage used by the stock firmware.
"Private" is a 320kB empty JFFS2 partition that comes with the stock
firmware. One can get a larger space for OpenWrt by merging it with
"Kernel".
OpenWrt flash layout:
```
0x000000000000-0x000000030000 : "u-boot"
0x000000030000-0x000000040000 : "u-boot-env"

0x000000fb0000-0x000001000000 : "private_stock"
```
The OpenWrt image must have 96 bytes of padding in the header.
MAC addresses on OEM firmware:
| | location on the flash | notes |
|------ |----------------------- |---------- |
| lan (eth2) | factory + 0xe000 | on label |
| wan (eth3) | factory + 0xe006 | |
| 2.4g (rax0) | not on flash | lan + 1 |
| 5g (ra0) | not on flash | lan + 2 |
Mac addresses of the 2.4g and 5g interface are stored as ASCII strings in
the u-boot-env partition, but they are not used. OpenWrt calculates
Wifi Mac addresses based on the LAN Mac.
Flash and test instructions:
Flash the encrypted image (available in the OpenWrt forum) through the
stock D-Dink web interface.
1. Open the case, and solder the 4-pin header near the WAN port.
2. Connect it to a USB-UART TTL (3.3V) adapter, no need to connect VCC.
3. Open a terminal emulator (e.g. `screen /dev/ttyUSB0` on linux) with
the settings mentioned above.
4. Setup a TFTP server on your PC that can serve
`xxx-ramips-mt7621-dlink_dir-853-a1-initramfs-kernel.bin`.
5. Connect any LAN port to your PC and set a static IPv4 address to
192.168.0.101 (netmask 255.255.255.0).
6. Power on the device and keeps pressing 1 until you see the prompt.
7. Use default IP addresses and enter the file name accordingly, then hit
enter.
8. Wait until it boots to OpenWrt, the default IP address is 192.168.1.1,
you need to change your PC network adapter to use DHCP in order to access
LUCI.
9. So far, the OpenWrt runs in RAM and the flash contents are not touched.
You can try OpenWrt without having to overwrite the stock firmware, a
reboot clears all changes.
10. Optionally, backup the stock firmware (the "firmware" partition) in
Luci.
11. To permantly install OpenWrt to the device , click
on "System -> Backup/Flash Firmware" in Luci and flash
`xxx-ramips-mt7621-dlink_dir-853-a1-squashfs-sysupgrade.bin`
Known problems:
* WLAN0 defaults to 5G after a fresh installation, to enable 2.4G network,
you need to config it manually in LUCI.
* If you see jffs2 related warnings/errors after updating from the stock
web interface, you need to do a reset in LUCI. The error will be gone after
a cold reboot.

Installation:
Factory firmware is based on a custom OpenWrt 17.x.
Installation is the same as for Xiaomi Mi Router 4A Gigabit.
Probably the easiest way to install is to use the script from
this repository: https://github.com/acecilia/OpenWRTInvasion/pull/155
In a more advanced case, you can do everything yourself:
- gain access to the device through one of the exploits described
in the link above
- upload sysupgrade image to /tmp
- overwrite stock firmware:
# mtd -e OS1 -r write /tmp/sysupgrade.bin OS1
Recovery:
Recovery procedure is the same as for Xiaomi Mi Router 4A Gigabit.
Possible options can be found here:
https://openwrt.org/inbox/toh/xiaomi/xiaomi_mi_router_4a_gigabit_edition
One of the ways is to use another router with OpenWrt:
- connect both routers by their LAN ports
- download stock firmware from [1]
- place it inside /tmp/test.bin on the main router
- configure PXE/TFTP on the main router
- power off 4Av2, hold Reset button, power on
- as soon as image download via TFTP starts, Reset can be released
- blinking blue wan LED will indicate the end of the flashing process,
now router can be rebooted
