Hi TI:
I have a self-developed AM3358 board with AR8031 to realize 1000M Enet in RGMII2
When I supply 3.3V to VDDSHV3 and ”ping ip -p 0xf0 -s 65000" , the probability of time out is about 30%
When I supply 2.5V to VDDSHV3 and ”ping ip -p 0xf0 -s 65000" , the probability of time out is less than 0.01%
When I supply 1.8V to VDDSHV3 and ”ping ip -p 0xf0 -s 65000" , the probability of time out is about 1%
According to AM3358 datasheet, VDDSHV3 can run in 3.3/1.8V power supply, can I supply VDDSHV3 with 2.5V Voltage?
