Hi,
We are using Am335x in a customized product hardware. We are testing the reset line used for Ethernet module. There are two reset lines connected to 10/100 and Gigabit Ethernet in our product hardware.
Currently we test the reset using GPIO’s. The procedure that we follow is as follows:
-
ifdown ethx or ifconfig ethx down
-
Set the GPIO corresponding to reset to low
For clearing the reset, we set the GPIO to high and then do an "ifup ethx". There is an issue with this sort of testing. Since we are using NFS boot for testing, we cannot break the Ethernet connection using "ifconfig eth0 down" or by turning off the PHY( through GPIO ).
So we wanted to check if there is any other way in which we can test the reset line attached to 10/100 or Gigabit Ethernet, such that it did not break the NFS connection. We could not find much information on this topic and not sure how I to this.
Can anyone help providing information regarding this as to if at all this is possible, if so how can this be done?
Thanks,
Sivaraj
