ramips: mt76x8: add support for Teltonika RUT241
Specification:
SoC: MediaTek MT7628AN
RAM: 128 MB EtronTech EM68C16CWQG-25IH
Flash: 16MB Winbond W25Q128 SPI
Switch: MediaTek MT7628AN, 2 ports 100 Mbps
WiFi: MediaTek MT7628AN 2.4 GHz 802.11n
Modem: MeigLink SLM750 4G, cat 4
GPIO:
- 1 button (Reset)
- 8 LEDs (2G, 3G, 4G, RSSI 1,2,3,4,5)
- 2 Modem control (power button, reset)
- 1 Digital input
- 1 Digital output
Flashing via OEM WebUI:
1. Download the firmware image *-squashfs-factory.bin
2. Upload firmware image via OEM WebUI firmware update, do not keep settings
To revert back to OEM firmware:
