To setup Ethernet takes more than 4 seconds in low_level_init().
Is the LAN8742A so slow and is the DP83848 in MII mode faster?
Thank you.

I don't have your hardware, and neither use LL code extensively.
But Cube (and LL) often employ busy loops to wait for ready flags during initialization. I would use a debugger to check what takes so long.
Perhaps waiting for a cable connection until timeout.

No one knows how to speed up Ethernet initialization?
