From 0f0ea1087b4c42a9fcdd5f003fef62cf587da40b Mon Sep 17 00:00:00 2001 From: Hank Moretti Date: Fri, 21 Jul 2023 03:54:52 +0000 Subject: [PATCH] mediatek: filogic: add support for Xiaomi WR30U Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: ESMT F50L1G41LB 128MB RAM: NT52B128M16JR-FL 256MB Ethernet: 4x 10/100/1000 Mbps Switch: MediaTek MT7531AE WiFi: MediaTek MT7976C Button: Reset, Mesh Power: DC 12V 1A Flash instructions: 1. Get ssh access Check this link: https://forum.openwrt.org/t/openwrt-support-for-xiaomi-ax3000ne/153769/22 2. Backup import partitions ``` dev: size erasesize name mtd1: 00100000 00020000 "BL2" mtd2: 00040000 00020000 "Nvram" mtd3: 00040000 00020000 "Bdata" mtd4: 00200000 00020000 "Factory" mtd5: 00200000 00020000 "FIP" mtd8: 02200000 00020000 "ubi" mtd9: 02200000 00020000 "ubi1" mtd12: 00040000 00020000 "KF" ``` Use these commands blow to backup your stock partitions. ``` nanddump -f /tmp/BL2.bin /dev/mtd1 nanddump -f /tmp/Nvram.bin /dev/mtd2 nanddump -f /tmp/Bdata.bin /dev/mtd3 nanddump -f /tmp/Factory.bin /dev/mtd4 nanddump -f /tmp/FIP.bin /dev/mtd5 nanddump -f /tmp/ubi.bin /dev/mtd8 nanddump -f /tmp/KF.bin /dev/mtd12 ``` Then, transfer them to your computer via scp, netcat, tftp or others and keep them in a safe place. 3. Setup Nvram Get the current stock: `cat /proc/cmdline` If you find `firmware=0` or `mtd=ubi`, use these commands: ``` nvram set boot_wait=on nvram set uart_en=1 nvram set flag_boot_rootfs=1 nvram set flag_last_success=1 nvram set flag_boot_success=1 nvram set flag_try_sys1_failed=0 nvram set flag_try_sys2_failed=0 nvram commit ``` If you find `firmware=1` or `mtd=ubi1`, use these commands: ``` nvram set boot_wait=on nvram set uart_en=1 nvram set flag_boot_rootfs=0 nvram set flag_last_success=0 nvram set flag_boot_success=1 nvram set flag_try_sys1_failed=0 nvram set flag_try_sys2_failed=0 nvram commit ``` 4. Flash stock-initramfs-factory.ubi If you find `firmware=0` or `mtd=ubi`: `ubiformat /dev/mtd9 -y -f /tmp/stock-initramfs-factory.ubi` If you find `firmware=1` or `mtd=ubi1`: `ubiformat /dev/mtd8 -y -f /tmp/stock-initramfs-factory.ubi` Then reboot your router, it should boot to the openwrt initramfs system now. 5. Setup uboot-env Now it will be setup automatically in upgrade process, you can skip this step. If your `fw_setenv` did not work, you need run this command: `echo "/dev/mtd1 0x0 0x10000 0x20000" > /etc/fw_env.config` Then setup uboot-env: ``` fw_setenv boot_wait on fw_setenv uart_en 1 fw_setenv flag_boot_rootfs 0 fw_setenv flag_last_success 1 fw_setenv flag_boot_success 1 fw_setenv flag_try_sys1_failed 8 fw_setenv flag_try_sys2_failed 8 fw_setenv mtdparts "nmbm0:1024k(bl2),256k(Nvram),256k(Bdata), 2048k(factory),2048k(fip),256k(crash),256k(crash_log), 34816k(ubi),34816k(ubi1),32768k(overlay),12288k(data),256k(KF)" ``` 6. Flash stock-squashfs-sysupgrade.bin Use shell command: `sysupgrade -n /tmp/stock-squashfs-sysupgrade.bin` Or go to luci web. If you need to change to Openwrt U-Boot layout, do next. If you do not need, please ignore it. Change to OpenWrt U-Boot: 1. Flash ubootmod-initramfs-factory.ubi Check mtd partitions: `cat /proc/mtd` ``` mtd7: 00040000 00020000 "KF" mtd8: 02200000 00020000 "ubi_kernel" mtd9: 04e00000 00020000 "ubi" ``` Run following command: `ubiformat /dev/mtd8 -y -f /tmp/ubootmod-initramfs-factory.ubi` Then reboot your router, it should boot to the openwrt initramfs system now. 2. Check mtd again ``` mtd7: 00040000 00020000 "KF" mtd8: 07000000 00020000 "ubi" ``` Make sure mtd8 is ubi. 3. Install kmod-mtd-rw Run command: `opkg update && opkg install kmod-mtd-rw` Or get it in openwrt server, or build it yourself, then install it manually Then run this command: `insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1` 4. Clean up pstore Run Command: `rm -f /sys/fs/pstore/*` 5. Format ubi and create new ubootenv volume ``` ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8 ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB ``` 6. (Optional) Add recovery boot feature. ``` ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB ubiupdatevol /dev/ubi0_2 /tmp/ubootmod-initramfs-recovery.itb ``` 7. Flash Openwrt U-Boot ``` mtd write /tmp/ubootmod-preloader.bin BL2 mtd write /tmp/ubootmod-bl31-uboot.fip FIP ``` 6. Flash ubootmod-squashfs-sysupgrade.itb Use shell command: `sysupgrade -n /tmp/ubootmod-squashfs-sysupgrade.itb` Or go to luci web. Now everything is done, Enjoy! Go Back to stock from Openwrt U-Boot: 1. Force flash ubootmod-initramfs-recovery.itb Use shell command: `sysupgrade -F -n /tmp/ubootmod-initramfs-recovery.itb` Or go to luci web. Then it should boot to the openwrt initramfs system now. 2. Format ubi and Nvram ``` ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8 mtd erase Nvram ``` 3. Install kmod-mtd-rw Run command: `opkg update && opkg install kmod-mtd-rw` Or get it in openwrt server, or build it yourself, then install it manually Then run this command: `insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1` 4. Flash stock U-Boot and ubi ``` mtd write /tmp/BL2.bin BL2 mtd write /tmp/FIP.bin FIP mtd write /tmp/ubi.bin ubi ``` Then reboot your router, waiting it finished rollback in minutes. Go Back to stock from stock layout Openwrt: Just run command: `ubiformat /dev/mtd8 -y -f /tmp/ubi.bin` Then reboot your router, waiting it finished rollback in minutes. Notes: 1. Openwrt U-Boot and ubootmod openwrt did not enable NMBM. Please make your backup safe.
