mediatek: add alternative UBI NAND layout for Linksys E8450 The vendor flash layout of the Linksys E8450 is problematic as it uses the SPI-NAND chip without any wear-leveling while at the same time wasting a lot of space for padding. Use an all-UBI layout instead, storing the kernel+dtb+squashfs in uImage.FIT standard format in UBI volume 'fit', the read-write overlay in UBI volume 'rootfs_data' as well as reduntant U-Boot environments 'ubootenv' and 'ubootenv2', and a 'recovery' kernel+dtb+initramfs uImage.FIT for dual-boot. ** WARNING ** THIS PROCEDURE CAN EASILY BRICK YOUR DEVICE PERMANENTLY IF NOT CARRIED OUT VERY CAREFULLY AND EXACTLY AS DESCRIBED! Step 0 * Configure your PC to have the static IPv4 address 192.168.1.254/24 * Provide bin/targets/mediatek/mt7622 via TFTP Now continue EITHER with step 1A or 1B, depending on your preference (and on having serial console wired up or not). Step 1A (Using the vendor web interface (or non-UBI OpenWrt install)) In order to update to the new bootloader and UBI-based firmware, use the web browser of your choice to open the routers web-interface accessible on http://192.168.1.1 * Navigate to 'Configuration' -> 'Administration' -> 'Firmware Upgrade' * Upload the file openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb and proceed with the upgrade. * Once OpenWrt comes up, use SCP to upload the new bootloader files to /tmp on the router: *-mt7622-linksys_e8450-ubi-preloader.bin *-mt7622-linksys_e8450-ubi-bl31-uboot.fip * Connect via SSH as you will now need to replace the bootloader in the Flash. ssh root@192.168.1.1 (the usual warnings) * First of all, backup all the flash now: for mtd in /dev/mtdblock*; do dd if=$mtd of=/tmp/$(basename $mtd); done * Then use SCP to copy /tmp/mtdblock* from the router and keep them safe. You will need them should you ever want to return to the factory firmware! * Now flow the uploaded files: mtd -e /dev/mtd0 write /tmp/*linksys_e8450-ubi-preloader.bin /dev/mtd0 mtd -e /dev/mtd1 write /tmp/*linksys_e8450-ubi-bl31-uboot.fip /dev/mtd1 If and only if both writes look like the completed successfully reboot the router. Now continue with step 2. Step 1B (Using the vendor bootloader serial console) * Use the serial to backup all /dev/mtd* devices before using the stock firmware (you got root shell when connected to serial). * Then reboot and select 'U-Boot Console' in the boot menu. * Copy the following lines, one by one: tftpboot 0x40080000 openwrt-mediatek-mt7622-linksys_e8450-ubi-preloader.bin tftpboot 0x40100000 openwrt-mediatek-mt7622-linksys_e8450-ubi-bl31-uboot.fip nand erase 0x0 0x180000 nand write 0x40080000 0x0 0x180000 reset Now continue with step 2 Step 2 Once the new bootchain comes up, the loader will initialize UBI and the ubootenv volumes. It will then of course fail to find any bootable volume and hence resort to load kernel via TFTP from server 192.168.1.254 while giving itself the address 192.168.1.1 The requested file is called openwrt-mediatek-mt7622-linksys_e8450-ubi-initramfs-recovery.itb and your TFTP server should provide exactly that :) It will be written to UBI as recovery image and booted. You can then continue and flash the production OS image, either by using sysupgrade in the booted initramfs recovery OS, or by using the bootloader menu and TFTP. That's it. Go ahead and mess around with a bootchain built almost completely from source (only DRAM calibration blobs are fitted in bl2, and the irreplacable on-chip ROM loader remains, of course). And enjoy U-Boot built with many great features out-of-the-box. You can access the bootloader environment from within OpenWrt using the 'fw_printenv' and 'fw_setenv' commands. Don't be afraid, once you got the new bootchain installed the device should be fairly unbrickable (holding reset button before and during power-on resets things and allows reflashing recovery image via TFTP) Special thanks to @dvn0 (Devan Carpenter) for providing amazingly fast infra for test-builds, allowing for `make clean ; make -j$(nproc)` in less than two minutes :) Signed-off-by: Daniel Golle <daniel@makrotopia.org>

mediatek: Add support for Xiaomi Redmi Router AX6S Also known as the "Xiaomi Router AX3200" in western markets, but only the AX6S is widely installation-capable at this time. SoC: MediaTek MT7622B RAM: DDR3 256 MiB (ESMT M15T2G16128A) Flash: SPI-NAND 128 MiB (ESMT F50L1G41LB or Gigadevice GD5F1GQ5xExxG) WLAN: 2.4/5 GHz 4T4R 2.4 GHz: MediaTek MT7622B 5 GHz: MediaTek MT7915E Ethernet: 4x 10/100/1000 Mbps Switch: MediaTek MT7531B LEDs/Keys: 2/2 (Internet + System LED, Mesh button + Reset pin) UART: Marked J1 on board VCC RX GND TX, beginning from "1". 3.3v, 115200n8 Power: 12 VDC, 1.5 A Notes: U-Boot passes through the ethaddr from uboot-env partition, but also has been known to reset it to a generic mac address hardcoded in the bootloader. However, bdata is also populated with the ethernet mac addresses, but is also typically never written to. Thus this is used instead. Installation: 1. Flash stock Xiaomi "closed beta" image labelled 'miwifi_rb03_firmware_stable_1.2.7_closedbeta.bin'. (MD5: 5eedf1632ac97bb5a6bb072c08603ed7) 2. Calculate telnet password from serial number and login 3. Execute commands to prepare device nvram set ssh_en=1 nvram set uart_en=1 nvram set boot_wait=on nvram set flag_boot_success=1 nvram set flag_try_sys1_failed=0 nvram set flag_try_sys2_failed=0 nvram commit 4. Download and flash image On computer: python -m http.server On router: cd /tmp wget http://<IP>:8000/factory.bin mtd -r write factory.bin firmware Device should reboot at this point. Reverting to stock: Stock Xiaomi recovery tftp that accepts their signed images, with default ips of 192.168.31.1 + 192.168.31.100. Stock image should be renamed to tftp server ip in hex (Eg. C0A81F64.img) Triggered by holding reset pin on powerup. A simple implementation of this would be via dnsmasq's dhcp-boot option or using the vendor's (Windows only) recovery tool available on their website.
