、
Easy Maintenance
Traditional WDT and GPIO programming are closely related to the hardware
with complicated test and debug process and software of different platforms;
however, the software developed by BPI only requires one set of the
maintenance software.
5
、
Low Cost
Developing the applications by BPI will not result in additional hardware and
software cost, but it will reduce the development difficulty, development cycle
and time-to-market for the system integrator.
Troubleshooting and Solutions
NO.
Phenomenon
Troubleshooting and Solution
Analysis: it could be the problem of the CMOS battery.
1
BIOS setting
cannot be saved
Solution: measure the CMOS battery with a multi-meter;
if the voltage is insufficient, replace the battery; re-set the
BIOS and save again.
Analysis: it may be caused by poor connection. Remove
the power plug from power socket on motherboard, you
may find that certain pin of the motherboard power has
been collapsed to one side after some forceful insertion.
2
The computer
can only be
powered-on
occasionally
Solution: power off the computer and remove the power
plug; erect the bended power pin with tweezers and
re-insert in the power socket. Reboot the computer and
test for several times until the problem no longer exits.
Analysis: A USB flash drive is a high-speed USB2.0;
when connecting with the computer, it prompts that a
high-speed device has been connected with a low-speed
connector, which indicates that the connector on
motherboard is regarded as a USB1.1 port.

When
connecting with
a USB flash
drive, the system
prompts that a
high-speed
device has been
connected with a
Solution: enable the USB high-speed transmission mode
on the motherboard. Different motherboards may have
different settings. Change the FULLSPEED option to
