Hello,
we are using Arty A7 for prototyping our product which has ethernet connection. After some time, the ethernet connection is not possible anymore and it seems that the PHY is defective.
However, it is not clear what could be the cause for this problem. It seems to be independent of the temperature of the environment. The time until it fails is also very random, from weeks to months.
Is there a way to find the reason for this and identify the failing component? Are there similar reports concerning this problem?
