6 Common Problems and Suggested Solutions
PROBLEM
ADDITIONAL INFORMATION
POSSIBLE SOLUTIONS
Cannot power on the EVM
2.5 Volt Power mode
D2 LED is off
•
J8: jumper pins 1-2 tied.
•
J10: jumper pins should be set to float.
•
Verify configuration with GUI.
3.3 Volt Power mode
D1 LED is off
•
J8: remove jumper shunt; this shunt needs to be removed to
enable 2.5 V regulator.
•
J10: jumper pins 9-10, 7-8, 5-6, 3-4, and 1-2 tied to connect
the regulator output to the DS560MB410 VDD supply.
Cannot connect to the
device in SMBus Target
Mode
SigCon Architect is operating in Demo Mode
•
Verify the jumper settings are correct.
•
Verify the target address is set to 0x30 for SMBus target
mode.
•
Verify the device is powered on.
•
Update Firmware on EVM using
USB2ANY Explorer
.
Never used SigCon Architect, and cannot
establish connection with device
•
Reinstall SigCon Architect. It is essential SigCon Architect is
closed during any portion of the installation process.
Oscilloscope’s Eye
Diagram is not as
expected
Pattern does not lock on oscilloscope
•
Transmit a signal from the pattern generator (for example,
BERT) with a different PRBS pattern. Once initial pattern
lock is established, re-attempt desired pattern.
•
Transmit a signal from the pattern generator (for example,
BERT) with a lower frequency. Once initial pattern lock is
established, re-attempt desired frequency.
Eye diagram does not pass mask
•
Vary EQ Boost Settings.
Cannot burn EEPROM
Hex File to EEPROM with
SigCon Architect
•
SigCon Architect can only be used to generate the Hex File.
Another interface adapter must be used to burn the Hex File
to the EEPROM. (for example, AARDVARK or equivalent ).
