Hi
I connected am4376 and l2 switch(rtl8367) with rgmii interface.
In this case, i want to change rgmii link speed 1000M to 100M.
When l2 switch linked 100M bps with external rj-45, clock pin of rgmii in AM4376 was not change 25Mhz in our board. fixed 125Mhz.
If link speed can change in software, how to change rgmii link speed?
