ramips: mt76x8: add support for Cudy LT300 v3
Hardware:
- SoC: MediaTek MT7628AN (MIPS 580MHz)
- Flash: 16 MiB NOR
- RAM: 64 MiB DDR2
- WLAN: 2.4 GHz (MT7628)
- Ethernet: 1x 10/100 Mbps WAN/LAN, 1x 10/100 LAN (MT7628)
- Build-in LTE Modem: MeigLink SLM770A
4G Cat. 4 (150/50 Mbps)
- Buttons: 1x Reset, 1x wps
- LEDs: Front: 1x Red, 1x White,
Back: 3x White 4G signal strengh
- Serial console: unpopulated header, 115200 8n1
- Power: USB-C
MAC addresses:
+---------+-------------------+-----------+
| | MAC | Algorithm |
+---------+-------------------+-----------+
| WAN | 80:af:ca:xx:xx:x1 | label+1 |
| LAN | 80:af:ca:xx:xx:x0 | label |
| WLAN 2g | 80:af:ca:xx:xx:x2 | label+2 |
+---------+-------------------+-----------+
Migration to OpenWrt:
- Download the RSA signed intermediate firmware from the Cudy website:
`openwrt-ramips-mt76x8-cudy_lt300-v3-squashfs-flash.bin`
- Connect computer to LAN and flash the intermediate firmware via OEM web interface
- OpenWrt is now accessible via 192.168.1.1
Revert back 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
- Press the reset button while powering on the device
- Recovery process is started now
- When recovery process is done, OEM firmware is accessible via 192.168.10.1 again
General information:
- No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot
