=== 2.5G Ethernet Connectivity Issues ===

If you encounter issues with the 2.5G Ethernet functionality on the Atum A5 development kit, please verify the hardware switch settings first.

==== Problem Description ====
The 2.5G Ethernet interface fails to establish a link or is unable to transmit data.

==== Solution ====
Please ensure that the '''SW26''' slide switch is configured correctly. This switch is used to set the Ethernet PHY address (PHY_ADR). If the setting is incorrect, the system will fail to identify the PHY chip properly.

'''Correct Switch Settings:'''
Set '''SW26.1 to ON''', and ensure all other switches (SW26.2, SW26.3, SW26.4) are set to '''OFF'''.
