Abstract
A JTAG interface device capable of effectively debugging a mobile terminal by interfacing the mobile terminal with a JTAG emulator without an additional interface unit by allocating test pins of the JTAG emulator to some pins of a receptacle and then electrically connecting the test pins to the pins, and a method thereof. Accordingly, an operation for debugging the mobile terminal can be easily and effectively performed.
Claims17
A JTAG testing system for a mobile terminal, the system comprising:
- a JTAG unit having a plug with a plurality of test pins for debugging the mobile terminal;
- and
- a receptacle mounted in the mobile terminal, having a plurality of pins corresponding to test pins of the JTAG unit for directly interfacing the mobile terminal with the JTAG unit.
A method of interfacing a JTAG unit to a mobile terminal for debugging the mobile terminal through the JTAG unit, the method comprising:
- allocating a plurality of test pins of a plug of the JTAG unit to a plurality of pins of a mobile terminal receptacle;
- connecting the each of the plurality of test pins of the JTAG unit plug to each of the plurality of pins of the mobile terminal receptacle;
- and
- performing debugging of the mobile terminal.
A method of interfacing a JTAG unit to a mobile terminal for debugging the mobile terminal through the JTAG unit, the method comprising:
- allocating a plurality of test pins of a plug of the JTAG unit to a plurality of pins of an existing mobile terminal receptacle;
- connecting the each of the plurality of test pins of the JTAG unit plug to each of the plurality of pins of the mobile terminal receptacle;
- and
- performing debugging of the mobile terminal.
A method of interfacing a JTAG unit to a mobile terminal for debugging the mobile terminal through the JTAG unit, the method comprising:
- adapting an existing mobile terminal receptacle to accommodate a plug of the JTAG unit having a plurality of test pins;
- allocating the plurality of test pins of the JTAG unit plug to a plurality of pins of the existing mobile terminal receptacle;
- connecting the each of the plurality of test pins of the JTAG unit plug to each of the plurality of pins of the mobile terminal receptacle;
- and
- performing debugging of the mobile terminal,
- wherein at least one of the plurality of pins of the existing mobile terminal receptacle that is connected to one of the plurality of test pins of the JTAG unit is used for a communication function of the mobile terminal.
