To turn off the whole IC and not only the buck converter use the IC_EN port (see also jumper link
J28). By toggling the position of the jumper to the alternative position, the whole IC goes off and the
current measured from the supply is close to zero.
DA9214 is a very powerful and flexible device, so it is possible that issues will arise through
continued and personalized usage. For questions and clarification please refer to your local Dialog
support team.

Troubleshooting
This section is an aid to resolving some of the more common issues.
8.1
Software Issues
The USB device should automatically install without difficulty. Make sure that the installation finds
and uses the driver contained on the supplied media.
If the program is started before the USB Interface board is plugged in, the program will default to the
offline mode. This can be useful to explore the software in a desk environment without the hardware
attached. If the board is subsequently attached, move the Interface control to
SAM3U I2C
or
SAM3U
SPI
.
The software can have unpredictable effects when used in conjunction with a USB hub. It is
recommended that a direct connection is made to the USB interface board.
The software is optimized for a display screen size of 1024 by 768 pixels or greater, with fonts set to
Normal (96dpi).
There have been reported issues of unpredictable display effects when large fonts (120dpi) are used.
This can be changed from the Window
Properties
,
Settings
tab; choose
Advanced
, then select
Normal size
from the drop-down menu.
If communications are apparently lost, first click the
Start Device
button. This attempts to make the
device go active. Also switching the
Interface mode
to
Offline
, then back to
USB
can reinitialize the
USB interface. Alternatively, unplug the USB then reconnect so that the software detects it and
reinitializes.
8.2
Hardware Issues
Most hardware problems can be traced to incorrect jumper positions.
Check carefully all jumper positions. Use the jumper table details and the board schematic as a guide
to the jumper functions and locations, see
Take particular care to ensure the power supply configuration is correct.
It is usually preferable that the USB is deactivated if the device supply is missing. This will mimic the
target system operation in which the host processor has no power if the PMIC has no supply. It also
avoids unintended current flow between a USB port output and an unpowered GPIO input.
