ipq40xx: add support for Linksys EA6350v3
Specifications: SOC: Qualcomm IPQ4018 RAM: 256 MiB Samsung K4B2G1646F-BYK0 FLASH1: MX25L1605D 2 MB FLASH2: Winbond W25N01GV 128Mb ETH: Qualcomm QCA8075 WLAN0: Qualcomm Atheros QCA4018 2.4GHz 802.11b/g/n 2x2 WLAN1: Qualcomm Atheros QCA4018 5GHz 802.11n/ac W2 2x2 INPUT: WPS, Reset LED: Status - Green SERIAL: Header at J19, Beneath DC Power Jack 1-VCC ; 2-TX ; 3-RX; 4-GND; Serial 115200-8-N-1. Tested and working: - USB (requires extra packages) - LAN Ethernet (Correct MAC-address) - WAN Ethernet (Correct MAC-address) - 2.4 GHz WiFi (Correct MAC-address) - 5 GHz WiFi (Correct MAC-address) - Factory installation from Web UI - OpenWRT sysupgrade - LED - Reset Button Need Testing: - WPS button Install via Web UI: - Attach to a LAN port on the router. - Connect to the Linksys Smart WiFi Page (default 192.168.1.1) and login - Select the connectivity tab on the left - In the manual update box on the right - Select browse, and browse to openwrt-ipq40xx-linksys_ea6350v3-squashfs-factory.bin - Click update. - Read and accept the warning - The router LED will start blinking. When the router LED goes solid, you can now navigate to 192.168.1.1 to your new OpenWrt installation. Sysupgrade: - Flash the sysupgrade image as usual. Please: try to do a reset everytime you can (doing it with LuCI is easy and can be done in the same step). Recovery (Automatic): - If the device fails to boot after install or upgrade, whilst the unit is turned on: 1 - Wait 15 seconds 2 - Switch Off and Wait 10 seconds 3 - Switch on 4 - Repeat steps 1 to 3, 3 times then go to 5. 5 - U-boot will have now erased the failed update and switched back to the last working firmware - you should be able to access your router on LAN. Recovery (Manual): - The steps for manual recovery are the same as the generic u-boot tftp client method. Back To Stock: - Use the generic recovery using the tftp client method to flash the "civic.img". Also you can strip-and-pad the original image and use the generic "mtd" method by flashing over the "kernel" partition. * Just be careful to flash in the partition that the device is currently booted.
