The hardware is very close the the Cudy M3000 v1 (see commit
20e4a18feb3f). However, the Motorcomm YT8821 PHY is tricky
to support because of a MDIO address collision within the router.
Specification:
- MT7981BA CPU: dual-core ARM Cortex-A53 @ 1.3 GHz
- 256 MiB RAM
- 128 MiB SPI NAND
- Ethernet:
- 1x 1GbE LAN port driven by the internal MT7981 PHY
- 1x 2.5GbE WAN port driven by the Motorcomm YT8821
- WiFi:
- MT7981BA 2.4 GHz WiFi with 2x2:2 MIMO
- MT7981BA 5 GHz WiFi with 2x3:2 MIMO
- Buttons: Reset, WPS
- LED: 1x combined red/white
How to know if you have the a router with the YT8821 PHY:
- Boot the router into the vendor's firmware. Go to Diagnostic Tools
-> System Log. Try searching for "rtl8221b".
- If there are some matches, you have the Cudy M3000 router with
the Realtek PHY and you should NOT use the device defined in this
commit. Instead, you should use the device defined in
mt7981b-cudy-m3000-v1.dts.
- If there are no matches, try searching for "yt8821". If that
matches something, you have the Cudy M3000 with the Motorcomm PHY
and you should use this device tree
(mt7981b-cudy-m3000-v2-yt8821.dts).
- If even the yt8821 string did not match anything, then something
is wrong. Rebooting the router might help (the system log would
be refreshed).
Installation via the Cudy web UI:
- Download the signed intermediary firmware from
https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj
- Flash the intermediary firmware using the Cudy web UI
- Connect a PC/laptop to the "1Gbps LAN" port
- Open http://192.168.1.1 in your browser, log in
(the password should be empty)
- Flash your desired OpenWrt firmware via LuCI
- The router should reboot into the desired firmware
How to access UART (citing from
20e4a18feb3f):
- remove rubber ring on the bottom
- remove screws
- pull up the cylinder, maybe help by push on an ethernet socket
with a screwdriver
- remove the (3) screws holding the board in the frame
- remove the board from the frame to get to the screws for the
silver, flat heat shield
- remove the (3) screws holding the heat shield
- solder UART pins to the back of the board
- make sure to have the pins point out on side with the black,
finned heat spread
- the markings for the pins are going to be below the silver heat
shield
- Vcc is not needed
- the UART parameters are 115200 baud, 8n1
Installation via UART (citing from
20e4a18feb3f):
- attach an Ethernet cable to the "1Gbps LAN" port on the router
- hold the reset button while powering the router
- press CTRL-C or wait for the timeout to get to the U-Boot prompt
- prepare a TFTP server on the network to supply ..-initramfs-kernel.bin
- use 'tftpboot 0x46000000 ..-initramfs-kernel.bin' in the U-Boot
shell to pull the image (change the file name accordingly)
- boot the image using 'bootm 0x46000000'
- push the ..-sysupgrade to the router using your preferred method
- perform the upgrade with 'sysupgrade -n'
