I need help with the following problem.
I am using an FRDM-K64F powered with an external 3.3V source.
When connecting ethernet port to pc, sometimes does not connect pc with K64F. After restarting the external source several times connect.
I can not find the reason. Can it be bad configuration of the ethernet port of the K64F? Problem in the transient current of the external source?
Thank you. Greetings.
