There are a few possible ways to troubleshoot this status message.
Diagnostic Step 1:
- Ensure that the Ethernet cable is secure on both sides and that the SP601 board is powered up.
Diagnostic Step 2:
- Two sequential steps:
- Unplug the Ethernet Cable from the SP601 board.
- Run the on-board BIST routine. This checks the connectivity between the Marvell PHY and the Spartan-6 FPGA.
Diagnostic Step 3:
- Two sequential steps:
- Once the BIST routine passes, plug the Ethernet cable back onto the SP601 board and connect other end to the PC Ethernet port.
- Verify that the Ethernet link is active by checking for the green flashing lights on the Ethernet port. Since the BIST has passed, red / orange flashing lights on the Ethernet port should flag issues with the PC-end Ethernet PHY / port.
Diagnostic Step 4:
- Once the Ethernet port shows that a link has been established (green lights flashing at about data rate), re-engage the connection to the FPGA by re-launching the Base Reference Design. This step should connect to the Spartan-6 FPGA; see image below:

Solution 1:
If all the Diagnostic Steps do not establish connection to the FPGA, and if you are using a PC running Windows Vista, re-install the Base System Reference Design (.msi file).
