Hi! I saw that ethernet is now supported in PX4, and was wondering if the DP83848Q PHY from TI is supported out of the box without substantial driver modification. If it isn’t, what steps would I need to take to get it working?
That depends on if NuttX supports it, we’re also on a NuttX hash from 2022. You should download the code base and search through the NuttX code for the part.
Got it, thanks. Do you know if there is any hardware configuration exposed on the board to board connectors going to a base board that could potentially affect the startup of the PHY?
Not sure about that. Did you get the phy enabled? I do see DP83848C in NuttX. What is the issue?
The PHY is enabled and gets configured correctly over MDIO, and there’s data coming in over the RXD lines, but netman update fails to execute with the same error as in Problem with ETH net.cfg . It also never falls back to the default IP. There weren’t any extra peripherals plugged in, and there definitely was an SD card inserted.
