Hi All,
SDK version: PROCESSOR-SDK-LINUX-AM57X 06_03_00_106
Fixed link is working but otherwise its not working.
PHY_RSTs are at gpio7_5 and 7_6, jack leds both are off orange and yellow.
Can someone guide on dtsi changes and phy resets part in dtsi?
Part number:KSZ9031RN
| Gigabit Ethernet PHY0 Address | PHYAD[2:0]=0x00 | |
| Gigabit Ethernet PHY1 Address | PHYAD[2:0]=0x01 |
we have enabled phy reset gpios for both the phys.
