Dongwon T&I DW02-412H is a 2.4/5GHz band 11ac (WiFi-5) router, based on
Qualcomm Atheros QCA9557.
Specifications
--------------
- SoC: Qualcomm Atheros QCA9557-AT4A
- RAM: DDR2 128MB
- Flash: SPI NOR 2MB (Winbond W25Q16DVSSIG / ESMT F25L16PA(2S)) +
NAND 64/128MB
- WiFi:
- 2.4GHz: QCA9557 WMAC
- 5GHz: QCA9882-BR4A
- Ethernet: 5x 10/100/1000Mbps
- Switch: QCA8337N-AL3C
- USB: 1x USB 2.0
- UART:
- JP2: 3.3V, TX, RX, GND (3.3V is the square pad) / 115200 8N1
Installation
--------------
1. Connect a serial interface to UART header and
interrupt the autostart of kernel.
2. Transfer the factory image via TFTP and write it to the NAND flash.
3. Update U-Boot environment variable.
> tftpboot 0x81000000 <your image>-factory.img
> nand erase 0x1000000
> nand write 0x81000000 0x1000000 ${filesize}
> setenv bootpart 2
> saveenv
Revert to stock firmware
--------------
1. Revert to stock U-Boot environment variable.
> setenv bootpart 1
> saveenv
MAC addresses as verified by OEM firmware
--------------
WAN: *:XX (label)
LAN: *:XX + 1
2.4G: *:XX + 3
5G: *:XX + 4
The label MAC address was found in art 0x0.
Credits
--------------
Credit goes to the @manatails who first developed how to port OpenWRT
to this device and had a significant impact on this patch.
And thanks to @adschm and @mans0n for guiding me to revise the code
in many ways.
