Flashing
 | NOTE: During configuration or flashing a device, the only things that should be hooked to the device is the computer and power. |
Flashing OpenWrt
 | This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 8MB FLASH / 64MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 8/64 warning for details. This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation. This means that you will not be able to install many packages, and that you might experience crashes due to OOM situations more or less often. See OpenWrt on 8/64 devices what you can do now. |

ramips: mt76x8: add support for Keenetic KN-3211 Keenetic KN-3211 is a 2.4 Ghz band 11n (Wi-Fi 4) Wi-Fi repeater, based on MT7628AN. Specification: - System-On-Chip: MT7628AN - CPU/Speed: 575 MHz - Flash-Chip: Winbond w25q256 - Flash size: 32768 KiB - RAM: 64 MiB - 1x 10/100 Mbps Ethernet - 2x external, non-detachable antennas - UART (J1) header on PCB (115200 8n1) - Wireless No1 (2T2R): SoC Built-in 2.4 GHz 802.11bgn - 3x LED, 1x button, 1x mode switch Notes: - The device supports dual boot mode - The firmware partitions were concatenated into one - The status button has been reassigned as the WPS button. Flash instruction: This device doesn't support sysupgrade, so the only way to flash OpenWrt image is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.1.2/24 and tftp server. 2. Rename "openwrt-ramips-mt76x8-keenetic_kn-3211-squashfs-factory.bin" to "KN-3211_recovery.bin" and place it in tftp server directory. 3. Connect PC with the ethernet port, press the reset button, power up the router and keep button pressed until power led starts blinking. 4. Router will download file from server, write it to flash and reboot. |
