Tool/software:
Hello TI /Expert.
We are using SDK 9.0 and we verify EVK SK-AM62B-P1, both Ethernet ports are able to set and support 1g speed.
In our custom board (HW/SW same as the EVK), but we use only PHY-1 (only one Ethernet port).
When we try to set 1g, Ethernet port is becoming disconnect or not detected (also not work). However if we set to 100mbps, it is detected and work fine.
Please guide to solve this problem. Thanks.
