ramips: mt76x8: add support for Cudy WR300 v1
Hardware: - SoC: MediaTek MT7628AN (MIPS 580MHz) - Flash: 8 MiB NOR - RAM: 64 MiB DDR2 - WLAN: 2.4 GHz (MT7628) - Ethernet: 1x 10/100 Mbps WAN, 3x 10/100 LAN (MT7628) - Buttons: 1x Reset, 1x wps - LEDs: Front: 1x Red, 1x White - Serial console: unpopulated header, 115200 8n1 - Power: 12v barrel MAC addresses: +---------+-------------------+-----------+ | | MAC | Algorithm | +---------+-------------------+-----------+ | LAN/WAN | d4:0d:ab:xx:xx:x0 | label | | WLAN 2g | d4:0d:ab:xx:xx:x1 | label+1 | +---------+-------------------+-----------+ Migration to OpenWrt: - Download the RSA-signed intermediate firmware from the Cudy website: `openwrt-ramips-mt76x8-cudy_wr300-squashfs-flash.bin` - Connect the computer to the LAN and flash the intermediate firmware via the OEM web interface - OpenWrt is now accessible via 192.168.1.1 Revert to OEM firmware: - Set up a TFTP server on IP 192.168.1.88 and connect to the WAN port (upper port) - Provide the Cudy firmware as `recovery.bin` in the TFTP server - Power on the device and hold the reset button immediately after the first LED blink - The recovery process will start - When the recovery process is done, OEM firmware is accessible via 192.168.10.1 again General information: - No possibility to load an initramfs image via U-Boot because there is no option to interrupt U-Boot Signed-off-by: Fil Dunsky <filipp.dunsky@gmail.com> Link: https://github.com/openwrt/openwrt/pull/23426 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
