ramips: add support for Z-ROUTER ZR-2662

2026-04-03T23:23:20Z

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 Link: https://github.com/openwrt/openwrt/pull/21524 Signed-off-by: Hauke Mehrtens

wifi-scripts: fix ucode erp_domain and fils_cache_id values

2026-04-03T22:18:31Z

The ucode path generates different erp_domain and fils_cache_id values than the legacy shell path due to three mismatches: 1. erp_domain md5 input missing trailing newline (echo adds \n) 2. erp_domain output truncated to 4 chars instead of 8 (shell uses head -c 8) 3. fils_cache_id md5 input missing trailing newline 4. erp_domain missing fallback to mobility_domain Same bug pattern as mobility_domain fixed in commit b1dc2736db.

ramips: mt76x8: add support for Cudy LT300 v3

2026-04-03T20:28:47Z

Hardware: - SoC: MediaTek MT7628AN (MIPS 580MHz) - Flash: 16 MiB NOR - RAM: 64 MiB DDR2 - WLAN: 2.4 GHz (MT7628) - Ethernet: 1x 10/100 Mbps WAN/LAN, 1x 10/100 LAN (MT7628) - Build-in LTE Modem: MeigLink SLM770A 4G Cat. 4 (150/50 Mbps) - Buttons: 1x Reset, 1x wps - LEDs: Front: 1x Red, 1x White, Back: 3x White 4G signal strengh - Serial console: unpopulated header, 115200 8n1 - Power: USB-C MAC addresses: +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | WAN | 80:af:ca:xx:xx:x1 | label+1 | | LAN | 80:af:ca:xx:xx:x0 | label | | WLAN 2g | 80:af:ca:xx:xx:x2 | label+2 | +---------+-------------------+-----------+ Migration to OpenWrt: - Download the RSA signed intermediate firmware from the Cudy website: `openwrt-ramips-mt76x8-cudy_lt300-v3-squashfs-flash.bin` - Connect computer to LAN and flash the intermediate firmware via OEM web interface - OpenWrt is now accessible via 192.168.1.1 Revert back to OEM firmware: - Set up a TFTP server on IP 192.168.1.88 and connect to the WAN port (upper port) - Provide the Cudy firmware as recovery.bin in the TFTP server - Press the reset button while powering on the device - Recovery process is started now - When recovery process is done, OEM firmware is accessible via 192.168.10.1 again General information: - No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot Signed-off-by: Fil Dunsky Link: https://github.com/openwrt/openwrt/pull/21982 Signed-off-by: Hauke Mehrtens

base-files: MAJOR/MINOR not sequential, use DISKSEQ instead

2026-04-03T18:40:49Z

Export the unique, monotonic DISKSEQ sequence drive number instead of its major/minor numbers to identify the boot disk and directly match the partition in export_partdevice with PARTN. The MINOR blockdevice numbers are not guaranteed sequential across disks, it can happen that disks enumerate before their partitions are probed, resulting in interleaved MINOR numbers breaking the partition offset calculation: major minor #blocks name 259 0 250059096 nvme0n1 259 2 8192 nvme0n1p1 259 3 491520 nvme0n1p2 259 4 239 nvme0n1p128 259 1 250059096 nvme1n1 259 5 250057728 nvme1n1p1 Signed-off-by: Clemens Hopfer Link: https://github.com/openwrt/openwrt/pull/18962 Signed-off-by: Robert Marko

mt76: pass LED define via ccflags-y

2026-04-03T17:13:17Z

Replace the deprecated EXTRA_CFLAGS with ccflags-y so that the -DCONFIG_MT76_LEDS define is applied correctly by the kernel build system. EXTRA_CFLAGS is no longer honored by recent kbuilds[1]; ccflags-y is the supported variable and works on kernels 6.12 and 6.18. 1. https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v6.18.20&id=f77bf01425b11947eeb3b5b54685212c302741b8 Signed-off-by: Mieczyslaw Nalewaj Link: https://github.com/openwrt/openwrt/pull/22737 Signed-off-by: Hauke Mehrtens
