Hi everyone,
I recently purchased a Linksys FGW5500 from AliExpress. It arrived pre-installed with a vendor-customized build of OpenWrt 23.05-SNAPSHOT (using a downstream Qualcomm 5.4 kernel).
The device is an IPQ5018-based 5G router with an internal M.2 slot containing a Quectel 5G modem. I am looking for guidance on how to properly add official OpenWrt support for it under the ipq50xx target.
Below is the complete hardware profile, partition layout, UART pinout, and boot logs.
Hardware Specifications
- SoC: Qualcomm IPQ5018 (2x Cortex-A53 @ 1.0 GHz)
- RAM: 512 MiB DDR3/DDR4 (Micron D9SHD)
- Flash: 512 MiB SPI NAND (GigaDevice GD5F4GM8REYIG)
- Cellular Expansion: M.2 Slot populated with a Quectel RM520N-GL 5G modem (operating in PCIe/MHI mode)
- Ethernet: * 1x 2.5G LAN
- 2x 1G LAN (managed via a QCA83xx/ISISC switch module)
- I/O Ports: 1x USB Port, 1x RJ11 Voice Port, Hardware Power Switch, Reset Button.
UART / Serial Console Pinout
There is a 4-pin header marked J9 on the PCB. The pinout from left to right (matching the square pin indicator) is as follows:
-
GND (Black)
-
RX (Orange)
-
TX (Green)
-
VCC 3.3V (Red - Do not connect when using a USB-to-TTL adapter)
Baud Rate: 115200
