ramips: add support for Z-ROUTER ZR-2662
This commit adds support for Z-ROUTER ZR-2662 (also known as Routerich AX1800 V2) wireless WiFi 6 router. Hardware specification --------------------- - SoC : MediaTek MT7621AT, MIPS, 880 MHz - RAM : 256 MiB - Flash : NAND 128 MiB (AMD/Spansion S34ML01G2) - WLAN : - 2.4 GHz : MediaTek MT7905D/MT7975 (14c3:7916), b/g/n/ax, MIMO 2x2 - 5 GHz : MediaTek MT7915E (14c3:7915), a/n/ac/ax, MIMO 2x2 - Ethernet : 10/100/1000 Mbps x4 (1x WAN, 3x LAN) - USB : 1x 2.0 - UART : 3.3V, 115200n8, pins are silkscreened on the pcb - Buttons : 1x Reset - LEDs : 1x WiFi 2.4 GHz (green) 1x WiFi 5 GHz (green) 1x LAN (green) 1x WAN (green) 1x WAN no-internet (red) - Power : 12 VDC, 1 A Installation ------------ 1. Run tftp server on your PC (IP: 192.168.2.2) and put OpenWrt initramfs image (initramfs.bin) to the tftp root dir 2. Open the following link in the browser to enable telnet: http://192.168.2.1/cgi-bin/telnet_ssh 3. Connect to the router (default IP: 192.168.2.1) using telnet shell (credentials - user:admin) 4. Run the following commands in the telnet shell (this will install OpenWrt initramfs image on nand flash): cd /tmp tftp -g -r initramfs.bin 192.168.2.2 mtd write initramfs.bin firmware mtd erase firmware_backup reboot 5. Copy OpenWrt sysupgrade image (sysupgrade.bin) to the /tmp dir of the router 6. Connect to the router (IP: 192.168.1.1) using ssh shell and run sysupgrade command: sysupgrade -n /tmp/sysupgrade.bin Return to stock --------------- 1. Copy stock firmware (stock.bin) to the /tmp dir of the router using scp 2. Run following command in the router shell: cd /tmp mtd write stock.bin firmware reboot Recovery -------- Connect uart (pins are silkscreened on the pcb), interrupt boot process by pressing any key, use u-boot menu to flash stock firmware image or OpenWrt initramfs image. MAC addresses ------------- +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | LAN | 24:0f:5e:xx:xx:4c | label | | WAN | 24:0f:5e:xx:xx:4d | label+1 | | WLAN 2g | 24:0f:5e:xx:xx:4e | label+2 | | WLAN 5g | 24:0f:5e:xx:xx:4f | label+3 | +---------+-------------------+-----------+ The WLAN 2.4 MAC was found in 'factory', 0x4 The LAN MAC was found in 'factory', 0xfff4 The WAN MAC was found in 'factory', 0xfffa Note: This device is similar to Z-ROUTER ZR-2660, but with minor hardware revisions. The firmware and configuration are compatible. Signed-off-by: xingchi <juncaixingchi2026@gmail.com> Link: openwrt#21524 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
