mediatek: add support for Mercusys MR90X v1 This commit adds support for Mercusys MR90X(EU) v1 router. Device specification -------------------- SoC Type: MediaTek MT7986BLA, Cortex-A53, 64-bit RAM: MediaTek MT7986BLA (512MB) Flash: SPI NAND GigaDevice GD5F1GQ5UEYIGY (128 MB) Ethernet: MediaTek MT7531AE + 2.5GbE MaxLinear GPY211C0VC (SLNW8) Ethernet: 1x2.5Gbe (WAN/LAN 2.5Gbps), 3xGbE (WAN/LAN 1Gbps, LAN1, LAN2) WLAN 2g: MediaTek MT7975N, b/g/n/ax, MIMO 4x4 WLAN 5g: MediaTek MT7975P(N), a/n/ac/ax, MIMO 4x4 LEDs: 1 orange and 1 green status LEDs, 4 green gpio-controlled LEDs on ethernet ports Button: 1 (Reset) USB ports: No Power: 12 VDC, 2 A Connector: Barrel Bootloader: Main U-Boot - U-Boot 2022.01-rc4. Additionally, both UBI slots contain "seconduboot" (also U-Boot 2022.01-rc4) Serial console (UART) --------------------- V +-------+-------+-------+-------+ | +3.3V | GND | TX | RX | +---+---+-------+-------+-------+ | +--- Don't connect The R3 (TX line) and R6 (RX line) are absent on the PCB. You should solder them or solder the jumpers. Installation (UART) ------------------- 1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2 2. Attach UART, switch on the router and interrupt the boot process by pressing 'Ctrl-C' 3. Load and run OpenWrt initramfs image: tftpboot initramfs-kernel.bin bootm 4. Once inside OpenWrt, set / update env variables: fw_setenv baudrate 115200 fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit" fw_setenv fdtcontroladdr 5ffc0e70 fw_setenv ipaddr 192.168.1.1 fw_setenv loadaddr 0x46000000 fw_setenv mtdids "spi-nand0=spi-nand0" fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)" fw_setenv netmask 255.255.255.0 fw_setenv serverip 192.168.1.2 fw_setenv stderr serial@11002000 fw_setenv stdin serial@11002000 fw_setenv stdout serial@11002000 fw_setenv tp_boot_idx 0 5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image Installation (without UART) --------------------------- 1. Login as root via SSH (router IP, port 20001, password - your web interface password) 2. Open for editing /etc/hotplug.d/iface/65-iptv (e.g., using WinSCP and SSH settings from the p.1) 3. Add a newline after "#!/bin/sh": telnetd -l /bin/login.sh 4. Save "65-iptv" file 5. Toggle "IPTV/VLAN Enable" checkbox in the router web interface and save 6. Make sure that telnetd is running: netstat -ltunp | grep 23 7. Login via telnet to router IP, port 23 (no username and password are required) 8 Upload OpenWrt "initramfs-kernel.bin" to the "/tmp" folder of the router (e.g., using WinSCP and SSH settings from the p.1) 9. Stock busybox doesn't contain ubiupdatevol command. Hence, we need to download and upload the full version of busybox to the router. For example, from here: https://github.com/xerta555/Busybox-Binaries/raw/master/busybox-arm64 Upload busybox-arm64 to the /tmp dir of the router and run: in the telnet shell: cd /tmp chmod a+x busybox-arm64 10. Check "initramfs-kernel.bin" size: du -h initramfs-kernel.bin 11. Delete old and create new "kernel" volume with appropriate size (greater than "initramfs-kernel.bin" size): ubirmvol /dev/ubi0 -N kernel ubimkvol /dev/ubi0 -n 1 -N kernel -s 9MiB 12. Write OpenWrt "initramfs-kernel.bin" to the flash: ./busybox-arm64 ubiupdatevol /dev/ubi0_1 /tmp/initramfs-kernel.bin 13. u-boot-env can be empty so lets create it (or overwrite it if it already exists) with the necessary values: fw_setenv baudrate 115200 fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit" fw_setenv fdtcontroladdr 5ffc0e70 fw_setenv ipaddr 192.168.1.1 fw_setenv loadaddr 0x46000000 fw_setenv mtdids "spi-nand0=spi-nand0" fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data)" fw_setenv netmask 255.255.255.0 fw_setenv serverip 192.168.1.2 fw_setenv stderr serial@11002000 fw_setenv stdin serial@11002000 fw_setenv stdout serial@11002000 fw_setenv tp_boot_idx 0 14. Reboot to OpenWrt initramfs: reboot 15. Login as root via SSH (IP 192.168.1.1, port 22) 16. Upload OpenWrt sysupgrade.bin image to the /tmp dir of the router 17. Run sysupgrade: sysupgrade -n /tmp/sysupgrade.bin Recovery -------- 1. Press Reset button and power on the router 2. Navigate to U-Boot recovery web server (http://192.168.1.1/) and upload the OEM firmware Recovery (UART) --------------- 1. Place OpenWrt initramfs image on tftp server with IP 192.168.1.2 2. Attach UART, switch on the router and interrupt the boot process by pressing 'Ctrl-C' 3. Load and run OpenWrt initramfs image: tftpboot initramfs-kernel.bin bootm 4. Do what you need (restore partitions from a backup, install OpenWrt etc.) Stock layout ------------ 0x000000000000-0x000000200000 : "boot" 0x000000200000-0x000000300000 : "u-boot-env" 0x000000300000-0x000003500000 : "ubi0" 0x000003500000-0x000006700000 : "ubi1" 0x000006700000-0x000006f00000 : "userconfig" 0x000006f00000-0x000007300000 : "tp_data" ubi0/ubi1 format ---------------- U-Boot at boot checks that all volumes are in place: +-------------------------------+ | Volume Name: uboot Vol ID: 0| | Volume Name: kernel Vol ID: 1| | Volume Name: rootfs Vol ID: 2| +-------------------------------+ MAC addresses ------------- +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | label | 00:eb:xx:xx:xx:be | label | | LAN | 00:eb:xx:xx:xx:be | label | | WAN | 00:eb:xx:xx:xx:bf | label+1 | | WLAN 2g | 00:eb:xx:xx:xx:be | label | | WLAN 5g | 00:eb:xx:xx:xx:bd | label-1 | +---------+-------------------+-----------+ label MAC address was found in UBI partition "tp_data", file "default-mac".
