Revision 1.1 (09-30-11)

PRELIMINARY - SMSC CONFIDENTIAL

 

Chapter 12 Troubleshooting

12.1

GUI Controls Unresponsive After Installation

Restart the computer. In some cases, a restart is required after installation.

12.2

GUI Freezes

If the GUI freezes for unknown reasons, communications cannot be stopped, and the program cannot
be closed, disconnect the USB cable from the EVB, then close the program. Reconnect the EVB, then
restart the GUI.

12.3

Random Panel Display

When an EVB is not connected to the PC running the GUI, the panel will be in an all zero register
displayed state. This also occurs when SMBus communications are disconnected. The panel display
is not meaningful. Connect the EVB and establish SMBus communications. If this still doesn’t work,
there’s a problem with the connection. The cable or the USB port could be bad. 

12.4

Device Is Not Charging or Not Charging Optimally

„

Check current limit jumper is set appropiately.

„

The current source may not have high enough capacity from VS. 

„

Run the Demo routine to determine highest current profile.
