Hardware: BPI-R4 v1.1 board
OpenWrt: 25.12.2 installed from firmware selector.
PSU: 12V/5A
The image is functional with the built in interfaces (WAN, LAN1, LAN2, LAN3).
However, my setup has a Quectel EG25G WWAN card in CN12 (SIM2) and two 1G Copper RJ45 adapters in the SFP WAN/LAN ports.
EG25G WWAN Card
The card initializes fine with /dev/cdc-wwan0 and /dev/ttyUSB0-3 ports. AT commands over /dev/ttyUSB2 work fine.
However, after a few minutes it starts looping through resets. Multiple /dev/cdc-wwan* show up. There is only one /dev/ttyUSB0 device;

The RJ45 SFP adapters do not initialize fully. ethtool for both ports report link not detected. Whereas the corresponding port on the Ethernet switch clearly shows the physical link is OK.
Looking at the early stage boot message shows mtk-xsphy failed to get a reference clock.

I suspect this is causing the instability with the EG25 modem card and the SFP RJ45 adapters.
I also tried to use the 24.10.5 image but the symptoms persist.
Is there a workaround to resolve this?
