ramips: mt7621: Add support for ZyXEL NR7101
The ZyXEL NR7101 is an 802.3at PoE powered 5G outdoor (IP68) CPE with integrated directional 5G/LTE antennas. Specifications: - SoC: MediaTek MT7621AT - RAM: 256 MB - Flash: 128 MB MB NAND (MX30LF1G18AC) - WiFi: MediaTek MT7603E - Switch: 1 LAN port (Gigabiti) - 5G/LTE: Quectel RG502Q-EA connected by USB3 to SoC - SIM: 2 micro-SIM slots under transparent cover - Buttons: Reset, WLAN under same cover - LEDs: Multicolour green/red/yellow under same cover (visible) - Power: 802.3at PoE via LAN port The device is built as an outdoor ethernet to 5G/LTE bridge or router. The Wifi interface is intended for installation and/or temporary management purposes only. UART Serial: 57600N1 Located on populated 5 pin header J5: [o] GND [ ] key - no pin [o] RX [o] TX [o] 3.3V Vcc Remove the SIM/button/LED cover, the WLAN button and 12 screws holding the back plate and antenna cover together. The GPS antenna is fixed to the cover, so be careful with the cable. Remove 4 screws fixing the antenna board to the main board, again being careful with the cables. A bluetooth TTL adapter is recommended for permanent console access, to keep the router water and dustproof. The 3.3V pin is able to power such an adapter. MAC addresses: OpenWrt OEM Address Found as lan eth2 08:26:97:*:*:BC Factory 0xe000 (hex), label wlan0 ra0 08:26:97:*:*:BD Factory 0x4 (hex) wwan0 usb0 random WARNING!! ISP managed firmware might at any time update itself to a version where all known workarounds have been disabled. Never boot an ISP managed firmware with a SIM in any of the slots if you intend to use the router with OpenWrt. The bootloader lock can only be disabled with root access to running firmware. The flash chip is physically inaccessible without soldering. Installation from OEM web GUI: - Log in as "supervisor" on https://172.17.1.1/ - Upload OpenWrt initramfs-recovery.bin image on the Maintenance -> Firmware page - Wait for OpenWrt to boot and ssh to root@192.168.1.1 - (optional) Copy OpenWrt to the recovery partition. See below - Sysupgrade to the OpenWrt sysupgrade image and reboot Installation from OEM ssh: - Log in as "root" on 172.17.1.1 port 22022 - scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp - Prepare bootloader config by running: nvram setro uboot DebugFlag 0x1 nvram setro uboot CheckBypass 0 nvram commit - Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot - Wait for OpenWrt to boot and ssh to root@192.168.1.1 - (optional) Copy OpenWrt to the recovery partition. See below - Sysupgrade to the OpenWrt sysupgrade image and reboot Copying OpenWrt to the recovery partition: - Verify that you are running a working OpenWrt recovery image from flash - ssh to root@192.168.1.1 and run: fw_setenv CheckBypass 0 mtd -r erase Kernel2 - Wait while the bootloader mirrors Image1 to Image2 NOTE: This should only be done after successfully booting the OpenWrt recovery image from the primary partition during installation. Do not do this after having sysupgraded OpenWrt! Reinstalling the recovery image on normal upgrades is not required or recommended. Installation from Z-Loader: - Halt boot by pressing Escape on console - Set up a tftp server to serve the OpenWrt initramfs-recovery.bin image at 10.10.10.3 - Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt - Wait for OpenWrt to boot and ssh to root@192.168.1.1 - Sysupgrade to the OpenWrt sysupgrade image NOTE: ATNR will write the recovery image to both primary and recovery partitions in one go. Booting from RAM: - Halt boot by pressing Escape on console - Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu - Press "4" to select "4: Entr boot command line interface." - Set up a tftp server to serve the OpenWrt initramfs-recovery.bin image at 10.10.10.3 - Load it using "tftpboot 0x88000000 initramfs-recovery.bin" - Boot with "bootm 0x8800017C" to skip the 380 (0x17C) bytes ZyXEL header This method can also be used to RAM boot OEM firmware. The warning regarding OEM applies! Never boot an unknown OEM firmware, or any OEM firmware with a SIM in any slot. NOTE: U-Boot configuration is incomplete (on some devices?). You may have to configure a working mac address before running tftp using "setenv eth0addr <mac>" Unlocking the bootloader: If you are unebale to halt boot, then the bootloader is locked. The OEM firmware locks the bootloader on every boot by setting DebugFlag to 0. Setting it to 1 is therefore only temporary when OEM firmware is installed. - Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware - Run "fw_setenv DebugFlag 0x1" in OpenWrt NOTE: OpenWrt does this automatically on first boot if necessary NOTE2: Setting the flag to 0x1 avoids the reset to 0 in known OEM versions, but this might change. WARNING: Writing anything to flash while the bootloader is locked is considered extremely risky. Errors might cause a permanent brick! Enabling management access from LAN: Temporary workaround to allow installing OpenWrt if OEM firmware has disabled LAN management: - Connect to console - Log in as "root" - Run "iptables -I INPUT -i br0 -j ACCEPT" Notes on the OEM/bootloader dual partition scheme The dual partition scheme on this device uses Image2 as a recovery image only. The device will always boot from Image1, but the bootloader might copy Image2 to Image1 under specific conditions. This scheme prevents repurposing of the space occupied by Image2 in any useful way. Validation of primary and recovery images is controlled by the variables CheckBypass, Image1Stable, and Image1Try. The bootloader sets CheckBypass to 0 and reboots if Image1 fails validation. If CheckBypass is 0 and Image1 is invalid then Image2 is copied to Image1. If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to Image2. If CheckBypass is 1 then all tests are skipped and Image1 is booted unconditionally. CheckBypass is set to 1 after each successful validation of Image1. Image1Try is incremented if Image1Stable is 0, and Image2 is copied to Image1 if Image1Try is 3 or larger. But the bootloader only tests Image1Try if CheckBypass is 0, which is impossible unless the booted image sets it to 0 before failing. The system is therefore not resilient against runtime errors like failure to mount the rootfs, unless the kernel image sets CheckBypass to 0 before failing. This is not yet implemented in OpenWrt. Setting Image1Stable to 1 prevents the bootloader from updating Image1Try on every boot, saving unnecessary writes to the environment partition. Keeping an OpenWrt initramfs recovery as Image2 is recommended primarily to avoid unwanted OEM firmware boots on failure. Ref the warning above. It enables console-less recovery in case of some failures to boot from Image1. Signed-off-by: Bjørn Mork <bjorn@mork.no>
