9 Debugging Environment and Method
In the process of the actual implementation, it is necessary to adopt the switching board to convert MINI
PCIE module interface into the standard USB interface to connect the host for debugging verification. It
is also necessary to connect external power supply adaptor to provide the module with sufficient current,
and the diagram for the switching board is as follows:

9.1 Debugging Board
Figure 9-2 shows the module debugging & installation method. The debugging board is mainly used to
debug the basic functions of ZM8620_V2 module, such as downloading the JTAG program, resetting the
module, powering off and shutting down RF, LED indicator display, making a call or browsing web
pages via computer UI by inserting the USIM card into the switching board. The USB interface supplies
power to the debugging board, provides it to the module after LDO conversion, and directly supplies the
power to the module by the power socket on the board.
