This commit adds OpenWrt U-Boot (UBI) layout support for MERCUSYS MR90X v1. Stock U-Boot UBI size: 50 MiB OpenWrt U-boot UBI size: 126 MiB Install ------- 1. Perform steps 1-14 of the OpenWrt installation guide (use OpenWrt initramfs-recovery.itb instead of initramfs-kernel.bin at the step 10, 12 and 14). Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation 2. 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. 3. Reboot to OpenWrt initramfs: ``` reboot ``` 4. 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. 5. 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 ``` 6. 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 ``` 7. 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 ``` 8. Write "factory" partition: ``` mtd erase factory mtd write /tmp/factory.bin factory ``` 9. Write preloader partition: ``` mtd erase bl2 mtd write /tmp/ubi-preloader.bin bl2 ``` 10. Write OpenWrt sysupgrade image: ``` sysupgrade -n /tmp/ubi-squashfs-sysupgrade.itb ``` Recovery -------- 1. Place OpenWrt initramfs-recovery.itb image (with original name) on the tftp server (IP: 192.168.1.254). 2. Press "reset" button and power on the router. After ~10 sec release the button. 3. 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 Link: https://openwrt.org/toh/mercusys/mr90x_v1#serial Return to stock: ---------------- 1. Copy "boot" partition backup (boot.bin) to the /tmp dir of the router using scp. 2. Install kmod-mtd-rw: ``` opkg update && opkg install kmod-mtd-rw ``` 3. Restore stock U-Boot: ``` insmod mtd-rw i_want_a_brick=1 mtd unlock boot mtd erase boot mtd write /tmp/boot.bin boot ``` 4. Erase UBI and reboot: ``` mtd erase ubi reboot ``` 5. Open U-Boot web recovery, upload stock firmware image and start upgrade. Link: http://192.168.1.1 6. Complete steps 1-9 of the OpenWrt installation guide to get root rights. Link: https://openwrt.org/toh/mercusys/mr90x_v1#installation 7. Upload "tp_data" partition backup (tp_data.bin) to the /tmp folder of the router using scp. 8. Restore stock calibrations: ``` mtd write /tmp/tp_data.bin tp_data reboot ``` 9. Perform "factory restore" via stock firmware web interface.
