Specification:
- MT7629 CPU
- MT7531 switch
- MT7761N and MT7762N wifi
- 256 MB RAM
- 128 MB NAND flash with dual-boot partitions
- 2 buttons: WPS and reset
- 1 WAN port (1G)
- 4 LAN ports (1G)
- 1 USB port
Limitations (same as other MT7629/MT7761N/MT7762N devices):
- Wifi is not working
- Second core is not working (kernel error message "CPU1: failed to come online")
Disassembly:
- There are two screws under the front rubber feet and two under the label on the bottom (in the corners towards the back, you should be able to feel them).
Serial Interface:
- UART pin header is already soldered on the board. Pinning from front to back:
1 - VCC
2 - TX
3 - RX
4 - n/a
5 - GND
GPIO:
- 1 white LED, connected to GPIO 52
- 1 reset button, connected to GPIO 60
- 1 WPS button, connected to GPIO 58
MAC Adresses:
- The MAC address printed on the device label is used for LAN and WAN
- The MAC address is stored in the devinfo partition in ASCII format (hw_mac_addr=aa:bb:cc:dd:ee)
- 2.4 GHz wifi uses MAC of the device label + 1
- 5 GHz wifi uses MAC of the device label + 2
Flashing:
- OpenWrt is only runnig in the first partition of dual boot
- To ensure to be able to go back to the factory image, flash the last OEM firmware via OEM web interface. This will ensure that the OEM firmware is present on both partitions
- Because of dual boot partitions, flashing via OEM interface is not supported
- Start a TFTP server and provide the initramfs image. Default settings:
- Router IP: 192.168.1.1
- TFTP server IP: 192.168.1.100
- TFTP file name: 7531.bin
- Open the device, connect UART and select " 1. System Load Linux to SDRAM via TFTP." during startup
- Adapt the settings to your environment, if required
- After initramfs is booted, flash the sysupgrade image
Return to OEM firmware:
- Run the following commands in OpenWrt to switch to the second partition
fw_setenv boot_part 2
fw_setenv bootimage 2
- Reboot the device. OEM firmware will start up again

In kernel 6.6, dts files for mediatek arm target are moved into
arch/arm/boot/dts/mediatek instead of legacy path arch/arm/boot/dts.
To avoid dts compile failure, change DTS_DIR to the mediatek subfolder
for kernel 6.6.

Device specification:
- MT7629 with 16MB NOR flash W25Q128 and 128 MB DDR3 RAM.
- MT7761N and MT7762N wireless chips (currenlty no driver in OpenWrt available)
- WiFi is NOT working on this device
- Dual core but second CPU doesn't seem to work (Error message during boot: "CPU1: failed to come online")
There are two similar merge requests for similar devices with the same issues:
- https://github.com/openwrt/openwrt/pull/12286
- https://github.com/openwrt/openwrt/pull/5084
UART interface is next to the reset button, pinout:
- 1: TX (the pin with the arrow marker)
- 2: RX
- 3: GND
- 4: VCC
UART settings: 115200,8n1, 3.3V
U-Boot menu can be entered by pressing Ctrl+B during startup.
Booting initramfs:
- Set your computers IP adress to 192.168.1.110
- Run a TFTP server providing the initramfs image
- Power on the AP, press Ctrl+B to get to the U-Boot menu
- Select "1. System Load Linux to SDRAM via TFTP"
- Update kernel file name, input server IP and input device IP (if they deviate from the defaults)
- After booting, create a backup of all partitions, especially for kernel and root_fs. They are required for reverting back to stock firmware
- The sysupgrade image can be flashed now
MAC adresses:
- LAN and 2.4GHz use the same MAC (the one printed on the device)
- 5GHz WiFi MAC is LAN MAC + 1
GPIOs:
- GPIO 21 is the reset pin (low active)
- GPIO 55 is for the green LED (active high)
- GPIO 56 is for the yellow/amber LED (active high)

Netgear EX6250v2, EX6400v3, EX6410v2, EX6470 are wall-plug 802.11ac
(Wi-Fi 5) extenders. Like other MT7629 devices, Wi-Fi does not work
currently as there is no driver.
Related: https://github.com/openwrt/openwrt/pull/5084
For future reference, 2.4GHz MAC = LAN+1, 5GHz MAC = LAN+2.
Specifications:
* MT7629, 256 MiB RAM, 16 MiB SPI NOR
* MT7761N (2.4GHz) / MT7762N (5GHz) - no driver
* Ethernet: 1 port 10/100/1000
* UART: 115200 baud (labeled on board)
Installation:
* Flash the factory image through the stock web interface, or TFTP to
the bootloader. NMRP can be used to TFTP without opening the case.
* After installation, perform a factory reset. Wait for the device to
boot, then hold the reset button for 10 seconds. This is needed
because sysupgrade in the stock firmware will attempt to preserve its
configuration using sysupgrade.tgz.
See https://github.com/openwrt/openwrt/pull/4182
Revert to stock firmware:
* Flash the stock firmware to the bootloader using TFTP/NMRP.

We need to reset KERNEL_LOADADDR if we use it on a per-device base.
Otherwise the previous value will be kept in case a device doesn't
define KERNEL_LOADADDR and relies on the default.
Move initializing KERNEL_LOADADDR to target/linux/mediatek/image/Makefile,
similar to how it's done also on the ramips target.
This fixes image size related breakage on devices which rely on the
default value of KERNEL_LOADADDR.
While at it use 0x48000000 which is more common than the previous default
0x44000000 for the filogic subtarget.

This harmonizes the device node names (and thus the image names, too)
between subtargets of the mediatek target. So far, each subtarget
has somewhat used its own naming scheme. Now, we use the vendor_device
syntax there, too.
Since DTS names have different patterns and the target only contains
a few devices, this does not replace DEVICE_DTS by a calculated
default value (like for other targets).
SUPPORTED_DEVICES is adjusted based on the node rename where necessary,
though it looks like for several older devices it was not set up
correctly so far.
While at it, this also changes the DTS name for u7623-02-emmc-512m
to all-lower-case.

base-files are added into subtarget directory like what's done
recently in ath79. For this subtarget, metadata checks are enforced
and a SUPPORTED_DEVICE is added to generate proper metadata.
Since we only have mt7629 support in 4.19, override KERNEL_PATCHVER
in target.mk for now.
