Description

[0002] Functional debugging is an important part of the equipment development process and an indispensable part of problem location and solution; generally, the debugging interface and the USB interface are independent of each other. During functional debugging, the debugging interface needs to be led out to carry out relevant debugging work.

[0003] In the process of overall machine debugging and testing, if occasional problems occur and the debugging interface is needed, if the relevant debugging signals are not led out in advance, it is very difficult to locate the cause of the problem only by the characteristics of the problem manifestation. At this time, to locate the cause of the problem, the debugging signals must be used; if the relevant debugging interface needs to be led out, the whole machine needs to be powered off and disassembled and assembled. Then the problem site state at this time is damaged, which may cause this problem to be difficult to reproduce later and the problem cannot be quickly located.

[0004] Therefore, in the existing functional debugging process, signals cannot be efficiently switched.

[0053] The following describes the method, apparatus, and device for switching between USB signals and debugging signals provided by the embodiments of the present disclosure with reference to the accompanying drawings.

[0054] Figure 1 It is a schematic flowchart of a method for switching between USB signals and debugging signals provided by the embodiments of the present disclosure.

[0055] Combined with Figure 1 As shown, the method for switching between USB signals and debugging signals may include:

[0056] S101, detecting the working mode requirements of the device, where the working mode requirements include the USB data transfer mode and the debugging mode;

[0057] S102, when it is detected that the working mode requirement is the USB data transfer mode, switching the signal path to the USB signal transmission path, and the USB signal transmission path is used to connect the USB interface and the data processing unit to implement data transfer of the device;

[0058] S103, when it is detected that the working mode requirement is the debugging mode, switching the signal path to the debugging signal transmission path, and the debugging signal transmission path is used to connect the debugging interface and the debugging processing unit to implement debugging of the device.

[0059] In some embodiments, Figure 1 the method in

[0060] may further include:

[0061] Receiving a working mode selection instruction input by the user through the operation interface of the device;

[0062] Determining the working mode requirements of the device according to the working mode selection instruction.

[0063] In some embodiments, the above-mentioned detecting the working mode requirements of the device may include:

[0064] Detecting the system status information of the device, where the system status information includes the startup status, running status, and error status of the device;

[0065] In some embodiments, the above-mentioned switching the signal path to the USB signal transmission path may include:

[0066] Based on the switching signal, controlling the switching switch to connect the differential data lines DP and DM of the USB interface to the pins of the data processing unit;

[0067] Disconnecting the connection between the debugging interface and the debugging processing unit.

[0068] In some embodiments, switching the signal path to the debug signal transmission path may include:

[0069] Controlling a switching switch based on a switching signal to connect a debug signal line of a debug interface to a corresponding debug pin of a debug processing unit;

[0070] Disconnecting the connection between the USB interface and the data processing unit.

[0071] In some embodiments, Figure 1 the method in

[0072] may further include:

[0073] During the signal path switching process, synchronously controlling the switching operation to ensure stable signal transmission during the switching process.

[0074] Before switching the signal path, sending a synchronization signal to the corresponding signal processing unit for the signal processing unit to record the signal path switching;

[0075] After receiving the confirmation response from the corresponding signal processing unit, performing the signal path switching operation.

[0076] In some embodiments, Figure 1 the method in

[0078] After the signal path switching is completed, performing signal quality detection on the switched signal path;

[0079] If it is detected that the signal quality does not meet the preset standard, perform signal compensation or re-switch the signal path.

[0080] Specifically, performing signal quality detection on the switched signal path includes detecting the quality of the USB signal and the debug signal, and thus signal compensation for signals that do not meet the preset standard can be achieved.

[0081] For debugging signal compensation: If the level of the debugging signal is abnormal, the signal level can be adjusted to the standard range through a level conversion circuit. If the signal frequency is abnormal, a frequency adjustment circuit can be used to calibrate the signal frequency to restore it to the standard frequency. For signal integrity issues, terminal matching resistors, decoupling capacitors, etc. can be used to improve the transmission characteristics of the signal, reduce reflections and interference, and improve signal integrity.

[0082] If the signal quality still does not meet the preset standard after signal compensation, the signal path switching operation is performed again. The working mode requirements of the device are detected again, and the USB signal transmission path or the debugging signal transmission path is reselected according to the requirements, and the above signal quality detection and compensation steps are repeated until the signal quality meets the preset standard.

[0083] Figure 2 is the switching schematic diagram of a switching circuit provided by an embodiment of the present disclosure. In combination with Figure 2 , for Figure 1 the switching method of the USB signal and the debugging signal in is further described.

[0084] In Figure 2 , U1 is a switching switch, which switches different output channels by changing the level state of the control signal (Switch_Ctrl), thereby realizing the switching of the USB signal and the debugging signal; under normal circumstances, the channel is default switched to the USB signal side, where the control signal is the above-mentioned switching signal.

[0085] In a specific example, a shortcut key (such as F1+0) can be defined in the firmware to realize the switching of the USB signal and the debugging signal functions. The default channel is switched to the USB signal. When the debugging signal needs to be used, the shortcut key is used to switch the channel to the debugging signal channel side for function debugging; after the debugging is completed, pressing the shortcut key again can switch the channel to the USB signal. The specific situation can be set according to actual needs.

[0086] The switching method of the USB signal and the debugging signal provided by the present disclosure can, based on the above switching circuit, switch the signal path by controlling the change of the switching signal, and thus can realize the accurate and efficient switching of the USB signal and the debugging signal.
