Hardware specification: SoC: MediaTek MT7987A Flash: 8GB eMMC RAM: 1GB DDR4 Ethernet: 2x 2.5GbE (RTL8221B PHY + Internal PHY) WiFi: MediaTek MT7992 / 2+3 antenna variant Interface: M.2 USB for 5G module LED: Power (hw-controlled), 2.5G WAN (user-definable), 5G Module (hw-controlled), LED-3 (user-definable), LED-4 (user-definable) Button: Reset, WPS Power: USB Type-C PD Other: PWM Fan control MAC address assignment is unconventional: the board has no Factory partition with pre-programmed MACs. Instead, all addresses are derived from the eMMC CID at runtime: LAN : macaddr_generate_from_mmc_cid mmcblk0 WAN : LAN + 1 (label_mac) phy0: LAN + 2 phy1: LAN + 3 This matches the vendor firmware behaviour and ensures stable, unique addresses across reboots without a dedicated EEPROM region for MACs. Flash instructions: Factory `mmcblk0p2` partition is empty, stock ImmortalWrt-798x-mt799x-6.6-mtwifi from PadavanOnly firmware uses `MT7991_MT7976_EEPROM_BE5040_iPAiLNA.bin`. Flashing this eeprom before flashing OpenWrt will make OpenWrt read eeprom: ``` dd if=/lib/firmware/MT7991_MT7976_EEPROM_BE5040_iPAiLNA.bin of=/dev/mmcblk0p2 bs=1 count=7680 sync ``` But it will have wifi issues for now. It's better to use OpenWrt fallback eeprom for now. Power off the device. Press and hold the Reset button. Power on the device while keeping the Reset button pressed. Wait for the device to enter U-Boot recovery mode. Connect to the device via Ethernet (default IP: 192.168.1.1). Set your PC's IP to 192.168.1.x (e.g., 192.168.1.100). Open a web browser and navigate to http://192.168.1.1 Upload and flash the OpenWrt firmware Wait for the flashing process to complete and the device to reboot.
