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.
| Switch | State | Description |
|---|---|---|
| SW26.1 | ON | Select 000 for PHYAD[4:2] |
| SW26.2 | OFF | Deselect 001 for PHYAD[4:2] |
| SW26.3 | OFF | Deselect 010 for PHYAD[4:2] |
| SW26.4 | OFF | Deselect 111 for PHYAD[4:2] |
