This commit adds OpenWrt U-Boot (UBI) layout support for TP-Link Archer AX80 v1 …EU Installation (UART): Place OpenWrt initramfs image on tftp server with IP 192.168.1.254 Attach UART, switch on the router and interrupt the boot process by pressing 'Ctrl-C' Load and run OpenWrt initramfs image: ``` tftpboot ubi-initramfs-recovery.itb bootm ``` Make backups: ``` cat /dev/mtd0 > /tmp/boot.bin cat /dev/mtd5 > /tmp/tp_data.bin ``` Copy /tp_data dir content, /tmp/boot.bin and /tmp/tp_data.bin and to your PC using scp. You can also backup the remaining partititons. Copy backups to a safe place, they are required for the next steps and stock firmware recovery. Reboot to OpenWrt initramfs: `reboot` Copy OpenWrt ubi-bl31-uboot.fip, ubi-preloader.bin, ubi-squashfs-sysupgrade.itb and MT7986_EEPROM.bin, default-mac (from /tp_data backup) to the /tmp folder of the router using scp. Prepare UBI: ``` ubidetach -p /dev/mtd3; ubiformat /dev/mtd3 -y; ubiattach -p /dev/mtd3 ubimkvol /dev/ubi0 -N fip -t static -s 1MiB ubiupdatevol /dev/ubi0_0 /tmp/ubi-bl31-uboot.fip ubimkvol /dev/ubi0 -N ubootenv -s 0x1f000 ubimkvol /dev/ubi0 -N ubootenv2 -s 0x1f000 ``` Install kmod-mtd-rw and unlock partitions: ``` opkg update && opkg install kmod-mtd-rw insmod mtd-rw i_want_a_brick=1 mtd unlock boot mtd unlock bl2 mtd unlock factory ``` Prepare "factory" partition: ``` dd if=/dev/zero bs=$((0x8000)) count=1 | tr '\000' '\377' > /tmp/factory.bin dd if=/tmp/MT7986_EEPROM.bin of=/tmp/factory.bin conv=notrunc dd if=/tmp/default-mac >> /tmp/factory.bin ``` Write "factory" partition: ``` mtd erase factory mtd write /tmp/factory.bin factory ``` Write preloader partition: ``` mtd erase bl2 mtd write /tmp/ubi-preloader.bin bl2 ``` Write OpenWrt sysupgrade image: `sysupgrade -n /tmp/ubi-squashfs-sysupgrade.itb` Recovery Place OpenWrt ubi-initramfs-recovery.bin image (with original name) on the tftp server (IP: 192.168.1.254). Press "reset" button and power on the router. After ~10 sec release the button. Use OpenWrt initramfs system for recovery. BL2 and FIP recovery Use mtk_uartboot and UART connetion if BL2 or FIP in UBI is destroyed: Link: https://github.com/981213/mtk_uartboot Return to stock: Copy "boot" partition backup (boot.bin) to the /tmp dir of the router using scp. Install kmod-mtd-rw: opkg update && opkg install kmod-mtd-rw Restore stock U-Boot: insmod mtd-rw i_want_a_brick=1 mtd unlock boot mtd erase boot mtd write /tmp/boot.bin boot Erase UBI and reboot: mtd erase ubi reboot Open U-Boot web recovery, upload stock firmware image and start upgrade. Link: http://192.168.1.1/ After reboot, upgrade with stock firmware image again via WebUI. Complete steps 1-4 of the Installation (UART). Link: https://github.com/openwrt/openwrt/pull/17753 Upload "tp_data" partition backup (tp_data.bin) to the /tmp folder of the router using scp. Restore stock calibrations: mtd write /tmp/tp_data.bin tp_data reboot Perform "factory restore" via stock firmware web interface.

It works, accept my PR please. Thank you. I think 3 days uptime I hit up, but electricity went down at night so.. Back at 8 hrs. It's all very similiar to my EU PR anyway. Just made some stuff better and cleaner too.
