Positioning to abnormal interruption is suitable for ARM platform, the interruption being abnormal can be positioned effective and rapidly, especially for interruption
Crash phenomenon caused by triggering with not rested is, it can be achieved that feedback problem is to user rapidly, in order to which user safeguards.
In one embodiment of the invention, before step S101, the method for interrupting positioning further include: in IRQ
The calling interface to the periodic sampling output function is inserted into the inlet of interrupt service routine.
Optionally, after the pop down code on the head of IRQ interrupt service routine, insertion exports letter to the periodic sampling
Several calling codes.
It should be noted that the interruption of all peripheral modules shares the same IRQ and interrupts service in the CPU of ARM system
The entrance of program, the entrance of IRQ interrupt service routine are used to carry out the press process of breakpoint address and general register.In IRQ
Disconnected service routine generallys use assembler language to realize.
In the present embodiment, in the inlet of IRQ interrupt service routine, increase the calling to periodic sampling output function.?
It is inserted into IRQ interrupt service routine and runs a cycle sampling output function.
In the processor, the interruption that every generation is once triggered by peripheral module will execute an IRQ and interrupt service journey
Sequence, a periodic sampling output function will be called by executing an IRQ interrupt service routine.Although interrupting can all call week every time
Phase samples output function, and still, periodic sampling output function is not to call all be sampled each time, but be spaced default
Duration or default interruption times can just sample once.
In the present embodiment, in the inlet of IRQ interrupt service routine, it is inserted into the calling to periodic sampling output function.It adopts
Exported with periodic samples rather than call the mode exported every time, and is subtracted as much as possible to simplify output information
Influence of the minor mode output code to program normal flow.
In one embodiment of the invention, IRQ interrupting information include the corresponding interrupt number of current interrupt service and/or in
Disconnected event, wherein interrupt number is the data in interrupt number register, and interrupt event is the data in interrupt event register.

Entrance variable element is stated, is then called.
In the present embodiment, periodic sampling output function is for periodically sampling while exporting IRQ interrupting information, this function
It is just output it after periodically sampling IRQ interrupting information.
In one embodiment of the invention, the periodic sampling output function by variable count, clock walk when or
Mode when timer travel realizes periodic samples and exports the IRQ interrupting information.
In one embodiment, the periodic sampling output function realizes periodic samples simultaneously in such a way that variable counts
Export the IRQ interrupting information, comprising:
1) static variable is defined, and its value is initialized as 0.
2) when calling the periodic sampling output function every time, the value of the static variable is added 1.
If 3) the value mould of the static variable samples except the value after preset sampling period number is 0 and exports the IRQ
Interrupting information.
4) otherwise, the IRQ interrupting information is not sampled, directly jumps out the periodic sampling output function.
In the present embodiment, preset sampling period number can be set according to the frequency speed of processor, such as 1000,
10000 etc..
Wherein, it is a kind of binary operation for not having exchangeability that mould, which removes,.For example, working as a=bq+r, q is integer, and is reached
Maximum, we say that a mould is equal to r except b at this time.
In one embodiment, the periodic sampling output function realizes periodic samples simultaneously by way of when clock is walked
Export the IRQ interrupting information, comprising:
1) when calling the periodic sampling output function every time, current time is read from system clock.
If 2) the value mould of the current time samples except the value after preset time cycle number is 0 and exports the IRQ
Interrupting information.

It is long.
If 3) timing time reaches preset duration, sample and export the IRQ interrupting information, and restart it is described fixed
When device so that timing time is reset to 0.
If 4) timing time does not reach the default time limit, the IRQ interrupting information is not sampled, continue to count
When, and directly jump out the periodic sampling output function.
In the present embodiment, preset duration can be 3 seconds, 5 seconds, 10 seconds etc..
As shown in Fig. 2, in one embodiment of the invention, the step S103 in embodiment corresponding to Fig. 1 includes:
Step S201 determines the interrupt number being abnormal by the IRQ interrupting information.
Optionally, by reading the data acquisition interrupt number in interrupt number register.
Step S202 determines peripheral module according to the interrupt number being abnormal, wherein the peripheral module is touching
Send out the external equipment of the interrupt number.
Optionally, processor-based technical manual can obtain the specific corresponding relationship of interrupt number and peripheral module, benefit
Step S202 may be implemented with the corresponding relationship.
Step S203 determines the interrupt event that triggering is interrupted according to the interrupt source of the peripheral module, and by the interruption thing
Part is as the abnormal interrupt event.
In one embodiment of the invention, step S201 includes:
1) interrupt number in the IRQ interrupting information is obtained.
If 2) interrupt number meets default exceptional condition, as the interrupt number being abnormal.
Wherein, it includes: interrupt number repeated multiple times appearance, Huo Zhe in preset duration that interrupt number, which meets default exceptional condition,
Other improper interrupt numbers are interrupted or are inserted into interrupt number with default association sequence.
In a particular application, the repeated multiple times appearance in preset duration is interrupted, can be shown as, some interruption is not stopped
Triggering with having a rest causes to crash.
In a particular application, it is not being beaten by taking a scene as an example according to the improper interruption that default association sequence occurs
During print, normal sequence is printed after first serial communication, and the sequence of interruption is answered are as follows: first there is the corresponding interruption of serial port module, after
The interruption of face immediately print module may be exactly if occurring the interruption of other peripheral modules triggering in the two are interrupted
Abnormal interruption.
In one embodiment of the invention, step S203 includes:
If 1) peripheral module has an interrupt source, an interrupt event is determined according to the interrupt source, as institute
State abnormal interrupt event.
If 2) peripheral module has at least two interrupt sources, by described in periodic sampling output function reading
Data in the corresponding interrupt event register of peripheral module, and determined according to the data in the interrupt event register read
The abnormal interrupt event.
In one embodiment, interrupt event includes interrupt status and interruption source.
It should be noted that the specific corresponding relationship of interrupt number and peripheral module, different processors is different, can join
See the technical manual of alignment processing device.
Peripheral module better simply for interrupt source, such as: timer, universal input and output module, it is specific to interrupt original
Because being exactly that the interrupt condition set reaches, system is additionally provided dedicated register no longer generally to indicate these peripheral modules
Interrupt status or specific interruption source.
The peripheral module more complex for interrupt source, such as: ethernet module, serial ports, USB module are specific to interrupt original
Because more, system generally provides dedicated register to indicate the specific interruption source of these peripheral modules.
Therefore, for the peripheral module at least two interrupt sources, the present embodiment exports letter by the periodic sampling
Number reads the data in the corresponding interrupt event register of the peripheral module.
The interrupt event register of peripheral module corresponding to different interrupt numbers is different, and the present embodiment is different only for occurring
The peripheral module of normal interrupt number.General location time-consuming can more be saved, improve location efficiency.
By taking a concrete application scene as an example, it is assumed that orienting abnormal peripheral module in step S202 is Ethernet mould
The interrupt source of block, ethernet module may include: the change of link state, receiver spilling, transmitter underload, in receiving frame
It is disconnected, send frame and interrupt etc., these interrupt sources by the corresponding interrupt event register of ethernet module that system provides not
It is indicated respectively with position.So, in step S203, the data in the corresponding interrupt event register of ethernet module are read,
So that it is determined that abnormal interrupt event.
The embodiment of the present invention has following technical effect that
