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 Signed-off-by: Roland Reinl <reinlroland+github@gmail.com> Link: https://github.com/openwrt/openwrt/pull/18609 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
