TROUBLESHOOTING
SOFTWARE INSTALLATION TIPS
Ethernet PHY software installation tips follow:
Always allow the software installation to be completed, and
keep in mind that the Ethernet PHY software is a two-part
installation including the ADI package installer (GUI and
documentation) and the FTDI drivers which can be found
at www.ftdichip.com/Drivers/CDM/CDM21228_Setup.zip.
The installation may require a restart of the PC.
When the MDIO interface dongle is first plugged in via the
USB cable, allow the new found hardware wizard to run
completely. This step is required prior to starting the
Ethernet PHY software.
If the EVAL-ADIN1300FMCZ does not appear in the GUI
window, ensure that the following steps have been
competed:
Power is applied to the EVAL-ADIN1300FMCZ.
The powered USB connector is connected to the MDIO
interface dongle.
Both the EVAL-ADIN1300FMCZ and the MDIO
interface dongle are connected together.
The Ethernet cable is connected.
The Ethernet PHY software is launched.
SOFTWARE TIPS
If the Ethernet PHY software does not read any data back,
check for any messages in the
Activity Log
section. There is one
known communication bug in the connection of the MDIO
interface dongle and EVAL-ADIN1300FMCZ, as discussed in
the following section.
MDIO Interface Dongle Communications, Known Issue
A known behavior when using the MDIO interface dongle with
the EVAL-ADIN1300FMCZ is related to the sequence of how
the boards are powered and connected together. If the GUI is
open, and the user connects the MDIO interface dongle to the
EVAL-ADIN1300FMCZ before connecting the USB power to
the MDIO interface dongle, the GUI may not properly establish
communications with the MDIO interface dongle.
The GUI polls for the MDIO interface dongle regularly, and if
an error in the MDIO interface dongle communications is
found, it is flagged in the
Activity Log
section and highlighted
in red font, as shown in Figure 35. The message also includes a
prompt explaining how to resolve the issue.
In the example shown in Figure 35, the user is advised to reset
the MDIO interface dongle through Button S6. There are two
buttons on the underside of the MDIO interface dongle. In this
case, the user identifies S6 and reset. This action restarts the
MDIO interface dongle. If the S6 restart does not resolve
communications, exit the GUI and relaunch the Ethernet PHY
software.

HARDWARE TIPS
Ensure that power is applied to the MDIO interface dongle and
EVAL-ADIN1300FMCZ as previously discussed. Measure the
voltage at various points on the EVAL-ADIN1300FMCZ using
the DVDD, VDD0P9, 5V, AVDD3P3, and VDDIO test points.
Crosscheck the voltages against the information in Table 1.
No Link Established
If no link is established, take the following steps to assist debug:
Ensure that the Ethernet cable is connected properly to the
RJ45 connector and between the EVAL-ADIN1300FMCZ
boards or PHY pairs.
When using two EVAL-ADIN1300FMCZ boards, ensure
that both boards are powered.
Ensure that the hardware configuration is appropriate for
the required linking arrangement.
LED Not Illuminated, but Link Established Reported in GUI
By default, LED_0 illuminates when a link is established, and
flashes when there is activity. The EVAL-ADIN1300FMCZ is
configured for Mode 3 and Mode 4 by default, with S1 in
Position 1. If PHY_CFG0 is to be used in Mode 1 or Model 2,
change the position of S1 to Position 2, as described in Table 4.
