Part Number:DP83640
Tool/software: Starterware
Hi,
i use dp83640 as the phy of my board, there is mode config for led as follow,
In Mode 1, LEDs are configured as follows:
LED_LINK = ON for Good Link, OFF for No Link
LED_SPEED = ON in 100 Mb/s, OFF in 10 Mb/s
LED_ACT = ON for Activity, OFF for No Activity
In Mode 2, LEDs are configured as follows:
LED_LINK = ON for Good Link, BLINK for Activity
LED_SPEED = ON in 100 Mb/s, OFF in 10 Mb/s
LED_ACT = ON for Collision, OFF for No Collision
In Mode 3, LEDs are configured as follows:
LED_LINK = ON for Good Link, BLINK for Activity
LED_SPEED = ON in 100 Mb/s, OFF in 10 Mb/s
LED_ACT = ON for Full Duplex, OFF for Half Duplex
the mode is MODE 2 in my board, but when it runs for many hours, the LED_LINK become blink（BLINK for Activity）, not ON.
After that, the commutication is failure.
What might be the reason？
Thanks.
Kevin
