The WR3000E has the same board layout as the WR3000S. Differences:
- Different flash chip
- LEDs with red/blue colour intead of white
Hardware:
- MediaTek MT7981 WiSoC
- 256MB DDR3 RAM
- 128MB SPI-NAND (F50L1G41LB)
- MediaTek MT7981 2x2 DBDC 802.11ax 2T2R (2.4 / 5)
MAC Addresses in OEM firmware:
- There is one on the label, e.g. AA:BB:CC:DD:EE:FF
- WLAN (2.4G) uses the same as on the label
- WLAN (5G) is the one on the label but
- first byte (e.g. AA) + 2
- fourth byte (e.g. DD) - 0x40
- WAN is the one on the label + 1
- LAN is the one on the label
MAC Addresses in OpenWrt:
- Same handling as in WR3000s is used
GPIO:
- 2 Buttons (all low active):
- WPS on GPIO 0
- Reset on GPIO 1
- 6 LEDs (all low active):
- Power: Blue on GPIO 8, no red LED
- WPS: Blue on GPIO 10, Red on GPIO 4
- Internet: Blue on GPIO 11, no red LED
- LAN: Blue on GPIO 9, Red on GPIO 5
- WiFi 2.4G: Blue on GPIO 6, no red LED
- WiFi 5G: Blue on GPIO 7, no red LED
Disassembly:
- Remove the 4 screws at the bottom of the case
- Cover is clipped to the bottom part of the case with clips in the front and the back
UART:
- UART pins are accessible on the bottom of the board
- The connector with the square shape is TX
- Pins: [ ] TX, ( ) RX, ( ) GND, ( ) VCC
- Settings: 115200 8N1 3.3V
Migration to OpenWrt via OEM firmware:
- There should be a migration image available from Cudy as soon as there is official OpenWrt support
- Download the migration image via OEM web interface
- After flashing, OpenWrt is accessible via 192.168.1.1
- Flash the official OpenWrt image
Migration to OpenWrt using TFTP:
- Connect UART as described above
- Press the reset button while powering on the device
- U-Boot will now try to load a recovery.bin via TFTP, this must be ignored
- After detecting a timeout, the U-Boot console is available via UART
- Set up a TFTP server on IP 192.168.1.88 and connect it to one of the LAN ports
- Provide the initramfs image via TFTP as cudy3000e.bin
- Run the following command in U-Boot: tftpboot 0x46000000 cudy3000e.bin; bootm 0x46000000
- OpenWrt initramfs image is now booting and accessible via 192.168.1.1
- Flash the sysupgrade image
Revert back to OEM:
- Set up a TFTP server on IP 192.168.1.88 and connect it to one of the LAN ports
- Provide the Cudy firmware via TFTP as recovery.bin
- Press the reset button while powering on the device
- Recovery process will start now
- After recovery is done, the OEM firmware is available at 192.168.10.1 again
