R32 is like the M32 part of the EAGLE PRO AI series from D-Link.
Specification:
- MT7622BV SoC with 2.4GHz wifi
- MT7975AN + MT7915AN for 5GHz
- MT7531BE Switch
- 512MB RAM
- 128 MB flash
- 2 LEDs (Status and Internet, both can be either orange or white)
- 2 buttons (WPS and Reset)
Compared to M32, the R32 has the following differences:
- 4 LAN ports instead of 2
- The recory image starts with DLK6E6015001 instaed of DLK6E6010001
- Individual LEDs for power and internet
- MAC address is stored at another offset in the ODM partition
MAC addresses:
- WAN MAC is stored in partition "Odm" at offset 0x81
- LAN (as printed on the device) is WAN MAC + 1
- WLAN MAC (2.4 GHz) is WAN MAC + 2
- WLAN MAC (5GHz) is WAN MAC + 3
Flashing via Recovery Web Interface:
- Set your IP address to 192.168.0.10, subnetmask 255.255.255.0
- Press the reset button while powering on the deivce
- Keep the reset button pressed until the internet LED blinks fast
- Open a Chromium based and goto http://192.168.0.1
- Download openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-a1-squashfs-recovery.bin
Flashing via uBoot:
- Open the case, connect to the UART console
- Set your IP address to 10.10.10.3, subnet mask 255.255.255.0. Connect to one of the LAN interfaces of the router
- Run a tftp server which provides openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-initramfs-kernel.bin.
- You can rename the file to iverson_uImage (no extension), then you don't have to enter the whole file name in uboot later.
- Power on the device and select "1. System Load Linux to SDRAM via TFTP." in the boot menu
- Enter image file, tftp server IP and device IP (if they differ from the default).
- TFTP download to RAM will start. After a few seconds OpenWrt initramfs should start
- The initramfs is accessible via 192.168.1.1, change your IP address accordingly (or use multiple IP addresses on your interface)
- Create a backup of the Kernel1 partition, this file is required if a revert to stock should be done later
- Perform a sysupgrade using openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-squashfs-sysupgrade.bin
- Reboot the device. OpenWrt should start from flash now
Revert back to stock using the Recovery Web Interface:
- Set your IP address to 192.168.0.10, subnetmask 255.255.255.0
- Press the reset button while powering on the deivce
- Keep the reset button pressed until the internet LED blinks fast
- Open a Chromium based and goto http://192.168.0.1
- Flash a decrypted firmware image from D-Link. Decrypting an firmware image is described below.
Decrypting a D-Link firmware image:
- Download https://github.com/RolandoMagico/firmware-utils/blob/M32/src/m32-firmware-util.c
- Compile a binary from the downloaded file, e.g. gcc m32-firmware-util.c -lcrypto -o m32-firmware-util
- Run ./m32-firmware-util R32 --DecryptFactoryImage <OriginalFirmware> <OutputFile>
- Example for firmware R32A1_FW103B01: ./m32-firmware-util R32 --DecryptFactoryImage R32A1_FW103B01.bin R32A1_FW103B01.decrypted.bin
Revert back to stock using uBoot:
- Open the case, connect to the UART console
- Set your IP address to 10.10.10.3, subnet mask 255.255.255.0. Connect to one of the LAN interfaces of the router
- Run a tftp server which provides the previously created backup of the Kernel1 partition.
- You can rename the file to iverson_uImage (no extension), then you don't have to enter the whole file name in uboot later.
- Power on the device and select "2. System Load Linux Kernel then write to Flash via TFTP." in the boot menu
- Enter image file, tftp server IP and device IP (if they differ from the default).
- TFTP download to FLASH will start. After a few seconds the stock firmware should start again
There is also an image openwrt-mediatek-mt7622-dlink_eagle-pro-ai-r32-a1-squashfs-tftp.bin which can directly be flashed via U-Boot and TFTP.
It can be used if no backup of the Kernel1 partition is reuqired.
Flahsing via OEM web interface is currently not possible, the OEM images are encrypted. Creating images is only possible manually at the moment.
The support for the M32/R32 already includes support for flashing from the OEM web interface:
- The device tree contains both partitions (Kernel1 and Kernel2) with conditions to select the correct one based on the kernel command line
- The U-Boot variable "boot_part" is set accordingly during startup to finish the partition swap after flashing from the OEM web interface
- OpenWrt sysupgrade flashing always uses the partition where it was initially flashed to (no partition swap)

Selecting the environment when booting from SD card has been broken by
a previous commit. Fix it.

Similar to the implementation for the BPi-R3 use the same logic also
for determining the device to look for the U-Boot environment of the
BPi-R64.

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.

All mediatek boards having fw_env accessible through uboot-envtools
belong to be mt7622 subtarget. Move the file, as subtarget-specific
files are supported for a while now.
