The VDD_1 pins of the first motionless termination pinboard, the GND pin of the second motionless termination USB connector J3.It is double by stirring hilted broadsword
Throw switch SW1 can select that the Update pins of control chip U1 are drawn high or dragged down, to be after controlling the upper electricity of product start
System enters different patterns, and such as selection enters firmware upgrade pattern or selection entered function debugging mode.
Embodiment three
Fig. 3 is the functional block diagram of a kind of electronic equipment that one embodiment of the invention is provided, the electronics that the present embodiment is provided
Equipment 300 includes the debug circuit 310 in above-described embodiment one.
Example IV
Fig. 4 is a kind of functional block diagram of debugging system that one embodiment of the invention is provided, as shown in figure 4, the present embodiment
The debugging system 400 of offer includes the debug circuit 410 in above-described embodiment 1 and the debugging apparatus in above-described embodiment 2
420.Single-pole double-throw switch (SPDT) SW1 movable end connection first not moved end or connection second not moved end when, can be by control chip U1
Update pins are drawn high or are dragged down, and debugging system 400 is entered different mode of operations, such as enter firmware upgrade pattern or work(
Can debugging mode.But for the chip of different model, the electricity needed for system into firmware upgrade pattern or function debugging pattern
Flat is different.
For example, for peace despot's S2L33m-A1-RH chips, when the not moved end of movable termination first of single-pole double-throw switch (SPDT) SW1
When, the DATA3_1 pins of pinboard are directly connected to VDD_1 pins, due to when pinboard insertion SD card seat J2 when, pinboard
DATA3_1 pins are ultimately connected to the Update pins of control chip U1 by SD card seat J2 and second switch U3, therefore
The level of Update pins is drawn high by VDD.After the Update pins of control chip U1 detect high level, debugging system is controlled
400 enter firmware upgrade pattern, and now the whole machine software of electronic product can be upgraded.
When the movable second not moved end of termination of single-pole double-throw switch (SPDT) SW1, the DATA3_1 pins of pinboard are directly connected to
Ground, is pulled low the level of the Update pins of control chip U1.After the Update pins of control chip U1 detect low level,
The host computers such as the control entered function debugging mode of debugging system 400, PC can be by USB connector in the whole machine of electronic product
The control chip U1 in portion sends instruction, carries out Commissioning Analysis and test.
But for peace despot's A9SE75 chips, when the not moved end of movable termination first of single-pole double-throw switch (SPDT) SW1, make control core
When the Update pins of piece U1 are drawn high by VDD, the entered function debugging mode of debugging system 400；As single-pole double-throw switch (SPDT) SW1 can
Moved end connects the second not moved end, and when the Update pins of control chip U1 is dragged down by GND, debugging system 400 enters firmware upgrade
Pattern.Therefore, it is necessary to select the closure of single-pole double-throw switch (SPDT) according to system requirements when actually used.
With usb signal be multiplexed the SD card signal of control chip by the present invention, when SD card seat insertion SD card, can be right
SD card carries out normal read-write operation；When SD card seat insertion modulating device, the whole machine of product can be debugged, and also can
By the different pattern of the switch selection on debugging apparatus, to solve the situation that SD card groove is only reserved in electronics external
Under, because the test point reserved on circuit board is wrapped in whole machine, thus it is not easy to carry out the research and development debugging of the whole machine of product, produces
The problem of the work such as line test.
The above, specific embodiment only of the invention, under above-mentioned teaching of the invention, those skilled in the art
Other improvement or deformation can be carried out on the basis of above-described embodiment.It will be understood by those skilled in the art that above-mentioned tool
The purpose of the present invention is simply preferably explained in body description, and protection scope of the present invention should be defined by scope of the claims.
