filogic: support Telenor branded ZyXEL EX5700 Telenor quirks -------------- The operator specific firmware running on the Telenor branded ZyXEL EX5700 includes U-Boot modifications affecting the OpenWrt installation. Notable changes to U-Boot include - environment is stored in RAM and reset to defaults when power cycled - dual partition scheme with "nomimal" or "rescue" systems, falling back to "rescue" unless the OS signals success in 3 attempts - several runtime additions to the device-tree Some of these modifications have side effects requiring workarounds - U-Boot modifies /chosen/bootargs in an unsafe manner, and will crash unless this node exists - U-Boot verifies that the selected rootfs UBI volume exists, and refuses to boot if it doesn't. The chosen "rootfs" volume must contain a squashfs signature even for tftp or initramfs booting. - U-Boot parses the "factoryparams" UBI volume, setting the "ethaddr" variable to the label mac. But "factoryparams" does not always exist. Instead there is a "RIP" volume containing all the factory data. Copying the "RIP" volume to "factoryparams" will fix this Hardware -------- SOC: MediaTek MT7986 RAM: 1GB DDR4 FLASH: 512MB SPI-NAND (Mikron xxx) WIFI: Mediatek MT7986 802.11ax 5 GHz Mediatek MT7916 DBDC 802.11ax 2.4 + 6 GHz ETH: MediaTek MT7531 Switch + SoC 3 x builtin 1G phy (lan1, lan2, lan3) 2 x MaxLinear GPY211C 2.5 N-Base-T phy (lan4, wan) USB: 1 x USB 3.2 Enhanced SuperSpeed port UART: 3V3 115200 8N1 (Pinout: GND KEY RX TX VCC) Installation ------------ 1. Download the OpenWrt initramfs image. Copy the image to a TFTP server reachable at 192.168.1.2/24. Rename the image to C0A80101.img. 2. Connect the TFTP server to lan1, lan2 or lan3. Connect to the serial console, Interrupt the autoboot process by pressing ESC when prompted. 3. Download and boot the OpenWrt initramfs image. $ env set uboot_bootcount 0 $ env set firmware nominal $ tftpboot $ bootm 4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device using scp and install using sysupgrade. $ sysupgrade -n <path-to-sysupgrade.bin> Missing features ---------------- - The "lan1", "lan2" and "lan3" port LEDs are driven by the switch but OpenWrt does not correctly configure the output. - The "lan4" and "wan" port LEDs are driven by the GPH211C phys and not configured by OpenWrt.
