Other Parts Discussed in Thread: DP83848K,
Tool/software:
In devices utilizing the AM3352 processor and DP83848K Ethernet PHY, during room-temperature stability testing, the host computer would intermittently lose ping connectivity to the device every 2-3 days. Serial debug outputs from the engineer indicated failure of the MAC subsystem within the AM3352. What potential root causes could lead to this persistent MAC functionality failure in the AM3352 that requires a chip reset to recover, rather than achieving self-recovery?
