We're running into some issues on our Pi5. We're connecting a sensor (A doppler velocity logger, Waterlinked DVL A50) over ethernet to the pi5. The DVL has a static ip address to which we set the eth0 device on the pi to be within the same subnet. When we plug the pi and DVL into a switch we can ping the sensor and everything works, however it doesn't work when we plug directly into the pi5. When plugged into the switch all the lights on the pi's ethernet port flash properly, but no lights turn on when plugged in directly.
Any ideas on what could be causing this?
Yes we've tried different cables, it also works when plugging into the pi via a USB-Ethernet adapter, however this isn't a great long term solution as we need those USB ports for other devices.
We do not have a crossover cable but everywhere online suggests that the auto-MDIX should handle that. We even tried making our own crossover cable and it still didn't work.
Here's the output from running ethtool eth0 when plugged directly into the sensor:And this is the output when plugged in through the switch and properly working
