Promblem:

The developing board cannot find the Ethernet contgroller LAN91C11 on debug board, so they cannot connect each other.

Solution:

The CPLD code have to burn again.

what's happen to CPLD?
what changes CPLD's code?

Problem:
the developing board cannot connect to JTEG for burning EBOOT.

Solution:
Take off back up battery, then it's working again (why? relate to PowerManager IC?)
but it still can't connect to EBOOT ( no messages from Terminal).
