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 Analog Devices, Inc.,
package installer (GUI,
data sheet, and EVAL-
ADIN1200FMCZ user guide) and the FTDI drivers which
can be found at the FTDI website The installation may
require a restart of the PC.
When the MDIO interface dongle is first plugged in via the
USB cable, allow the found new hardware wizard to run
completely. This step is required prior to starting the
Ethernet PHY software.
If the EVAL-ADIN1200FMCZ does not appear in the GUI
window, ensure that the following steps have been
completed:
Power is applied to the EVAL-ADIN1200FMCZ.
The powered USB connector is connected to the MDIO
interface dongle.
Both the EVAL-ADIN1200FMCZ 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-ADIN1200FMCZ, as
discussed in the MDIO Interface Dongle Communications
Known Issue section.
MDIO Interface Dongle Communications Known Issue
A known behavior when using the MDIO interface dongle with
the EVAL-ADIN1200FMCZ 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-ADIN1200FMCZ 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 36. The message also includes a
prompt explaining how to resolve the issue.
In the example shown in Figure 36, the user is advised to reset
the MDIO interface dongle via Button S6. There are two buttons
on the underside of the MDIO interface dongle. In this case, the
user must identify 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-ADIN1200FMCZ as previously discussed in the Power
Sequencing section. Measure the voltage at various points on
the EVAL-ADIN1200FMCZ using the AVDD_3P3 and
VDDIO test points. Crosscheck the voltages against the
information in Table 1.
No Link Established
If no link is established, use the following steps to assist debug:
Ensure that the Ethernet cable is connected properly to the
registered Jack 45 (RJ45) connector and between the
evaluation boards or PHY pairs.
When using two EVAL-ADIN1200FMCZs, 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-ADIN1200FMCZ 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 Mode 2,
change the position of S1 from 1 to 2, as described in Table 4.
