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)

Acelink EW-7886CAX is an MT7986A (AKA Filogic 830) based access point.
It has 512 MiB of RAM, one 2.5 Gbps PoE (802.3at) Ethernet port and
on-SoC Wi-Fi. There is no printed MAC label (on my unit).
My unit came with Mediatek's firmware (based on OpenWrt 21.02)
installed. It was possible to simply upgrade using OpenWrt's sysupgrade
tool.
Another verified upgrade method is using U-Boot (requires UART). During
every boot there is "U-Boot Boot Menu". Selecting option "2. Upgrade

Features and fixes from hitech95 tree has been squashed, I'm attaching his commit message:
The Power LED was not working correctly and not reacting
to the boot process and statuses.
The board has space (footprint) for an unpopulated Zigbee chip,
while we dont know the device model having this chip populated
we have to assure that the common dts doesnt enable
interfaces that share pins with such device.
In this instance the PCIe and the uart1 and uart2 are disabled.
Some of the control PCIE pins seems to be used for the Zigbee chip,
UART1 seems to be used as a flash port while UART2 should be the
main comunication interface of Zigbee chip.
The Zigbee chip should be a EFR32MG21. But the pins used for UART
seems to be not on standard PINS used by other adapters.
So it cannot run firmwares shared on the web.
But it should be possible to build a custom firmware with
the corrtect pinmux.

- After booting, create a backup of all partitions, especially for kernel and root_fs. They are required for reverting back to stock firmware
- The sysupgrade image can be flashed now
MAC adresses:
- LAN and 2.4GHz use the same MAC (the one printed on the device)
- 5GHz WiFi MAC is LAN MAC + 1
GPIOs:
- GPIO 21 is the reset pin (low active)
- GPIO 55 is for the green LED (active high)
- GPIO 56 is for the yellow/amber LED (active high)

Specification:
- MT7622BV SoC with 2.4GHz wifi
- MT7975AN + MT7915AN for 5GHz
- MT7531BE Switch
- 512MB RAM
- 128 MB flash
- 3 LEDs (red, orange, white)
- 2 buttons (WPS and Reset)
MAC addresses:
- WAN MAC is stored in partition "Odm" at offset 0x83
- 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
Disassembly: Remove 4 screws in the bottom and 2 screws in the top (after removing the blue cover on the top), then the board can be pulled out.
The pins for the serial console are already labeled on the board (VCC, TX, RX, GND). Serial settings: 3.3V, 115200,8n1
Flashing via Recovery Web Interface:
- Set your IP address to 192.168.0.10, subnetmask 255.255.255.25
- Press the reset button while powering on the deivce
- Keep the reset button pressed until the status LED blinks fast
- Open a Chromium based and goto http://192.168.0.1
- Download openwrt-mediatek-mt7622-dlink_eagle-pro-ai-m32-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-m32-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-m32-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 255.255.255.25
- Press the reset button while powering on the deivce
- Keep the reset button pressed until the status 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 M32 --DecryptFactoryImage <OriginalFirmware> <OutputFile>
- Example for firmware 1.03.01_HOTFIX: ./m32-firmware-util M32 --DecryptFactoryImage M32-REVA_1.03.01_HOTFIX.enc.bin M32-REVA_1.03.01_HOTFIX.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-m32-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 and require a specific memory layout which is not compatible to the partition layout of OpenWrt.
