mediatek: add alternative stock layout for Xiaomi Redmi Router AX6000 In this implementation, the flash partition layout is adjusted to avoid modifying the uboot environment of mtdparts. This ensures that the 30M ubi_kernel partition remains aligned with the stock ubi partition, and the kernel volume is placed in it. This allows the stock uboot to boot from it without changing the mtdparts, which is useful for reverting back to the stock firmware using Xiaomi Firmware Tools. In actual testing, modifying mtdparts has been found to break Xiaomi Firmware Tools. 1. use ARTIFACTS to generate initramfs-factory.ubi for easy installation. 2. The NAND flash layout is changed to allow for reverting back to the stock firmware. 3. Before performing sysupgrade, do some cleanup in platform_pre_upgrade to ensure a clean installation of OpenWRT. 4. Setup the uboot env to ensure that the system always boot, which can be helpful for users who may forget to do this before sysupgrade in the initramfs. New flash instructions: 1. Gain ssh access. Please refer to: https://openwrt.org/toh/xiaomi/redmi_ax6000#installation) 2. Check which system current u-boot is loading from: COMMAND: `cat /proc/cmdline` sample OUTPUT: `console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1` if firmware=1, current system is ubi1 if firmware=0, current system is ubi0 3. Setup nvram and write the firmware: If the current system is ubi1, please set it up so that the next time it will boot from ubi, and write the firmware to ubi: ``` 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 ubiformat /dev/mtd8 -y -f /tmp/initramfs-factory.ubi ``` If the current system is ubi, please set it up so that the next time it will boot from ubi1, and write the firmware to ubi1: ``` 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 ubiformat /dev/mtd9 -y -f /tmp/initramfs-factory.ubi ``` 4. After rebooting, the system should now boot into the openwrt initramfs. Flash the squashfs-sysupgrade.bin via using ssh or luci. ``` sysupgrade -n /tmp/squashfs-sysupgrade.bin ``` Done. For existing users of the Redmi AX6000 running OpenWrt, here are the steps to switch to this new layout: 1. Flash initramfs-factory.ubi ``` mtd -r -e ubi write /tmp/initramfs-factory.ubi ubi ``` 2. After rebooting, the system will boot into the new openwrt-initramfs. Log in and perform a sysupgrade to complete the process. ``` sysupgrade -n /tmp/squashfs-sysupgrade.bin ``` Signed-off-by: Chen Minqiang <ptpt52@gmail.com> Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

uboot-mediatek: add support for Xiaomi Redmi Router AX6000 U-Boot flash instructions: 0. OpenWrt U-Boot does not support stock layout, it comes with recovery boot support, automatic tftp recovery and never blocks UART. A new flash layout is introduced, we call it OpenWrt U-Boot layout, stock flash layout and the old OpenWrt layout are not supported. During the whole flash procedure, please do not reboot or power off unless requested explicitly, or you will break your device. 1. Your device should already running OpenWrt. If not, follow the instructions to flash OpenWrt: https://github.com/openwrt/openwrt/pull/11115 2. Backup BL2 Nvram Bdata Factory and FIP in case you break something or in case you want to go back to stock firmware one day. cat /dev/mtdblock0 > /tmp/BL2.bin cat /dev/mtdblock1 > /tmp/Nvram.bin cat /dev/mtdblock2 > /tmp/Bdata.bin cat /dev/mtdblock3 > /tmp/Factory.bin cat /dev/mtdblock4 > /tmp/FIP.bin And save all whose bin files to somewhere safe. Then backup your configurations, since ubiformat for entire mtd device is required to create new ubootenv volume for OpenWrt U-Boot. 3. Run the following cmd to boot into an initramfs with the new OpenWrt U-Boot layout that expand ubi partion to the end of flash: ubiformat /dev/mtd7 -y -f /tmp/ax6000-ubootmod-initramfs-factory.ubi 4. After boot into initramfs, check mtd partion info. The ubi partion should be mtd5 root@OpenWrt:~# cat /proc/mtd dev: size erasesize name mtd0: 00100000 00020000 BL2 mtd1: 00040000 00020000 Nvram mtd2: 00040000 00020000 Bdata mtd3: 00200000 00020000 Factory mtd4: 00200000 00020000 FIP mtd5: 07a80000 00020000 ubi 5. Load kmod-mtd-rw to temporarily make the bootloader partions writable. The kmod-mtd-rw is from the feeds, it is not packed in initramfs-factory by default. To install kmod-mtd-rw via opkg: opkg update && opkg install kmod-mtd-rw Or, download kmod-mtd-rw.ipk from OpenWrt server and install it manually e.g: https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/kmods/ Select your OpenWrt release version and kernel version accordingly. Load kmod-mtd-rw: insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1 6. Run the following cmd to clean all pending crash dumps in pstore, or OpenWrt U-Boot may boot into NAND recovery or tftp recovery. rm -f /sys/fs/pstore/* 7. Format ubi and create new ubootenv volume: ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5 ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB 8. This is optional. Skip this if you do not want to have NAND recovery boot feature offered by OpenWrt U-Boot. Don't worry, you always have automatic tftp recovery feature enabled. ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB ubiupdatevol /dev/ubi0_2 /tmp/ax6000-ubootmod-initramfs-recovery.itb 9. Now, flash new U-Boot. Bye-bye ugly stock U-Boot. mtd write /tmp/ax6000-ubootmod-preloader.bin BL2 mtd write /tmp/ax6000-ubootmod-bl31-uboot.fip FIP 10. Flash the squashfs-sysupgrade.bin as usual: sysupgrade -n /tmp/ax6000-ubootmod-squashfs-sysupgrade.itb Enjoy! Signed-off-by: Furong Xu <xfr@outlook.com>

mediatek: add support for Zyxel EX5601-T0 router Zyxel EX5601-T0 specifics -------------- The operator specific firmware running on the Zyxel branded EX5601-T0 includes U-Boot modifications affecting the OpenWrt installation.

U-boot has hardcoded a command to always launch Zloader "mtd read zloader 0x46000000" and than "bootm". Bootargs are deactivated. Zloader is the zyxel booloader which allow to dual-boot ubi or ubi2, by default access to zloader is blocked. Too zloader checks that the firmware contains a particolar file called zyfwinfo. Additional details regarding Zloader can be found here: https://hack-gpon.github.io/zyxel/ https://forum.openwrt.org/t/adding-openwrt-support-for-zyxel-ex5601-t0/155914 Hardware -------- SOC: MediaTek MT7986a CPU: 4 core cortex-a53 (2000MHz) RAM: 1GB DDR4 FLASH: 512MB SPI-NAND (Micron xxx) WIFI: Wifi6 Mediatek MT7976 802.11ax 5 GHz 4x4 + 2.4GHZ 4x4 ETH: MediaTek MT7531 Switch + SoC 3 x builtin 1G phy (lan1, lan2, lan3) 1 x MaxLinear GPY211B 2.5 N-Base-T phy5 (lan4) 1 x MaxLinear GPY211B 2.5Gbit xor SFP/N-Base-T phy6 (wan) USB: 1 x USB 3.2 Enhanced SuperSpeed port UART: 3V3 115200 8N1 (Pinout: GND KEY RX TX VCC) VOIP: 2 FXS ports for analog phones MAC Address Table ----------------- eth0/lan Factory 0x002a eth1/wan Factory 0x0024 wifi 2.4Ghz Factory 0x0004 wifi 5Ghz Factory 0x0004 + 1 Serial console (UART) --------------------- +-------+-------+-------+-------+-------+ | +3.3V | RX | TX | KEY | GND | +---+---+-------+-------+-------+-------+ | +--- Don't connect Installation ------------ Keep in mind that openwrt can only run on the UBI partition, the openwrt firmware is not able to understand the zloader bootargs. The procedure allows restoring the UBI partition with the Zyxel firmware and retains all the OEM functionalities. 1. Unlock Zloader (this will allow to swap manually between partitions UBI and UBI2): - Attach a usb-ttl adapter to your computer and boot the router. - While the router is booting at some point you will read the following: `Please press Enter to activate this console.` - As soon as you read that press enter, type root and than press enter again (just do it, don't care about the logs scrolling). - Most likely the router is still printing the boot log, leave it boot until it stops. - If everything went ok you should have full root access "root@EX5601-T0:/#". - Type the following command and press enter: "fw_setenv EngDebugFlag 0x1". - Reboot the router. - As soon as you read `Hit any key to stop autoboot:` press Enter. - If everything went ok you should have the following prompt: "ZHAL>". - You have successfully unlocked zloader access, this procedure must be done only once. 2. Check the current active partition: - Boot the router and repeat the steps above to gain root access. - Type the following command to check the current active image: "cat /proc/cmdline". - If `rootubi=ubi` it means that the active partition is `mtd6` - If `rootubi=ubi2` it means that the active partition is `mtd7` - As mentioned earlier we need to flash openwrt into ubi/mtd6 and never overwrite ubi2/mtd7 to be able to fully roll-back. - To activate and boot from mtd7 (ubi2) enter into ZHAL> command prompt and type the following commands: atbt 1 # unlock write atsw # swap boot partition atsr # reboot the router - After rebooting check again with "cat /proc/cmdline" that you are correctly booting from mtd7/ubi2 - If yes proceed with the installation guide. If not probably you don't have a firmware into ubi2 or you did something wrong. 3. Flashing: - Download the sysupgrade file for the router from openwrt, than we need to add the zyfwinfo file into the sysupgrade tar. Zloader only checks for the magic (which is a fixed value 'EXYZ') and the crc of the file itself (256bytes). I created a script to create a valid zyfwinfo file but you can use anything that does exactly the same: https://raw.githubusercontent.com/pameruoso/OpenWRT-Zyxel-EX5601-T0/main/gen_zyfwinfo.sh - Add the zyfwinfo file into the sysupgrade tar. - Enter via telnet or ssh into the router with admin credentials - Enter the following commands to disable the firmware and model checks "zycli fwidcheck off" and "zycli modelcheck off" - Open the router web interface and in the update firmware page select the "restore default settings option" - Select the sysupgrade file and click on upload. - The router will flash and reboot itself into openwrt from UBI 4. Restoring and going back to Zyxel firmware. - Use the ZHAL> command line to manually swap the boot parition to UBI2 with the following: atbt 1 # unlock write atsw # swap boot partition atsr # reboot the router - You will boot again the Zyxel firmware you have into UBI2 and you can flash the zyxel firmware to overwrite the UBI partition and openwrt. Working features ---------------- 3 gbit lan ports Wifi Zyxel partitioning for coexistance with Zloader and dual boot. WAN SFP port (only after exporting pins 57 and 10. gpiobase411) leds reset button serial interface usb port lan ethernet 2.5 gbit port (autosense) wan ethernet 2.5 gbit port (autosense) Not working ---------------- voip (missing drivers or proper zyxel platform software) Swapping the wan ethernet/sfp xor port ---------------- The way to swap the wan port between sfp and ethernet is the following: export the pins 57 and 10. Pin 57 is used to probe if an sfp is present. If pin 57 value is 0 it means that an sfp is present into the cage (cat /sys/class/gpio/gpio468/value). If pin 57 value is 1 it means that no sfp is inserted into the cage. In conclusion by default both 57 an 10 pins are by default 1, which means that the active port is the ethernet one. After inserting an SFP pin 57 will become 0 and you have to manually change the value of pin 10 to 0 too. This is totally scriptable of course. Leds description ------------ All the leds are working out of the box but the leds managed by the 2 maxlinear phy (phy 5 lan, phy6 wan). To activate the phy5 led (rj45 ethernet port led on the back of the router) you have to use mdio-tools. To activate the phy6 led (led on the front of the router for 2.5gbit link) you have to use mdio-tools. Example: Set lan5 led to fast blink on 2500/1000, slow blink on 10/100: mdio mdio-bus mmd 5:30 raw 0x0001 0x33FC Set wan 2.5gbit led to constant on when wan is 2.5gbit: mdio mdio-bus mmd 6:30 raw 0x0001 0x0080 Signed-off-by: Pietro Ameruoso <p.ameruoso@live.it>
