The Linksys E8450, also known as Belkin RT3200, is a dual-band
IEEE 802.11bgn/ac/ax router based on MediaTek MT7622BV and
MediaTek MT7915AN chips.
FCC: K7S-03571 and K7S-03572
Hardware highlights:
- CPU: MediaTek MT7622BV (2x ARM Cortex-A53 @ 1350 MHz max.)
- RAM: 512MB DDR3
- Flash: 128MB SPI-NAND (2k+64)
- Ethernet: MT7531BE switch with 5 1000Base-T ports
CPU port connected with 2500Base-X
- WiFi 2.4 GHz: 802.11bgn 4T4R built-in antennas
MT7622VB built-in
- WiFi 5 GHz: 802.11ac/ax 4T4R built-in antennas
MT7915AN chip on-board via PCIe
MT7975AN front-end
- Buttons: Reset and WPS
- LEDS: 3 user controllable LEDs, 4 wired to switch
- USB: USB2.0, single port
- no Bluetooth (supported by SoC, not wired on board)
- Serial: JST PH 2.0MM 6 Pin connector inside device
----_____________----
[ GND RX - TX - - ]
---------------------
- JTAG: unpopulated ARM JTAG 20-pin connector (works)
This commit adds support for the device in a way that is compatible
with the vendor firmware's bootloader and dual-boot flash layout, the
resulting image can directly be flashed using the vendor firmware.
