5.4.4 Debugging Board

I.
Functions and Usage of the Debugging board
The debugging board developed by Huawei is an auxiliary board that is used to
debug the EM770.When the debugging board is used, you can connect the module
to a PC through a USB cable. When the module works normally, the debugging
functions can be implemented. The debugging board provides multiple interfaces,
such as the USB port, DC power jack, mini PCI-E connector, BTB connector, SIM
card socket, RF connectors, PCM audio interface, and serial ports (including a 4-pin
serial port and a serial port that all pins are led out). The test points of key signals are
led out on the debugging board. In addition, the debugging board is designed with
switches or pins of commonly used signals such as the reset signal and the enable
signal, for converting the working state of the module.
The debugging board can be used to test the performance of the module. Both the
wired connection test (connect the module to the CMU200) and the wireless
