Hi,
I recently change the ethernet PHY from KSZ8721 to DP83848K on my board under MII mode, the MAC is STM32F207VE,
for now everything works fine but the linkspeed mode is 10Mb-half duplex,
when I "PING" to the established MAC connection it may have an 1us pulse on "DP83848 COL" pin during each "PING",
the straping of linkspeed for DP83848K I left AN0 and AN1 floating, so it should be able to auto-negotiate with 10/00 BASE-T, Half/Full-Duplex, right?
can you give me some suggestions where I can debug with this?
