Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

Please refer to FIG. 1 , which is a flowchart of an eye diagram testing method provided by an embodiment of the present application. The method includes:

S101: Acquire target data, and write the target data into a target file.

Some or all of the steps of the eye diagram testing method provided in this embodiment may be performed by a designated electronic device, and the specific type and model of the electronic device are not limited. For example, in a feasible implementation manner, the electronic device may be a display device, such as a VR (Virtual Reality, virtual reality technology) device, an AR (Augmented Reality, augmented reality technology) device, or other devices having a display screen. In another feasible implementation manner, the electronic device may be a device having a USB (Universal Serial Bus, Universal Serial Bus) interface. It should be noted that, when the electronic device is running, the data in its registers and memory cannot be directly read and written. The eye diagram test is very important for electronic devices that use differential signals for data transmission. If the eye diagram test fails, it means that there is a problem with the signal transmission, which may cause abnormal communication during use. This abnormality varies according to the type of electronic device. For example, for display devices, the abnormality may be a Huaping abnormality; for electronic devices with a USB interface, the abnormality may be an abnormality that cannot be recognized by the USB interface, or an abnormality that uses a USB interface. The exception that the transmission result is wrong when the interface performs data transmission.

The target data can be input by the user to modify the data in the registers and the memory. This embodiment does not limit the specific size, format and quantity of the target data, which can be set according to actual needs. It can be understood that there can be multiple target data, which are respectively used for writing to different locations of the target file; the format of the target data can be a directly written format, or a format that is convenient for transmission or a format with a smaller data size. When writing, it can be formatted first, and then written to the target file. This embodiment does not limit the specific acquisition method of the target data, for example, the target data may be acquired from a specified path, or the target data may be acquired from a specified device or terminal. In a feasible implementation manner, the target data can be obtained by using a test interface on the electronic device, and the specific type of the test interface is not limited, for example, it can be an ADB interface, that is, an ADB (Android Debug Bridge, Android Debug Bridge) port, A port for development debugging.

The target file is specifically a file that stores register data, and is also a file that allows register reading, and its specific format is not limited. The target file also allows the writing of target data. It can be understood that the register data in the target file is the full data of a register, which corresponds to the register. Since the number of registers may be one or more, the target file Data corresponding to one or more registers may also be recorded. Further, the target data written in the target file can be used to replace all the data in the target file, or can be used to replace or modify part of the data in the target file. For example, when register data corresponding to multiple registers is recorded in the target file, the target data can be used to replace data corresponding to a certain register in the target file. The target data is written to the register to read the target data, so that the data in the register can be modified during the operation of the electronic device. By using the target file to transfer the target data, the restriction that the data in the register cannot be directly modified is bypassed by the method of first writing and then reading, so that the data in the register is modified.

S102: Read the register data in the target file to the register.

It can be understood that this embodiment does not limit the specific execution timing of reading the register data in the target file to the register, that is, does not limit when the target file is read. In one embodiment, the data in the target file can be read to the register immediately after it is detected that the target data is written into the target file; in another embodiment, the data in the target file can be read when the read instruction is detected. The register data is read to the register, and whether the read command is generated or not is independent of whether the target data is written in the target file. This embodiment also does not limit the manner in which the control register reads the register data in the target file. For the specific manner, reference may be made to the related art, which will not be repeated in this embodiment. The target file is read through the control register, and the register data in it is obtained and stored, that is, the register data in the target file is read into the register, so that the device software can not be recompiled and the electronic device has not been restarted. Replace the data in the register.

It should be noted that, each time the register data is read, the target file can be read in full, that is, all data in the target file can be read into the register; in another embodiment, the target file can be partially read. Read, that is, select part of the data in the target file to read to the register, so as to reduce the time required to read the register data and improve the efficiency of eye diagram testing.

S103: Refresh the register data in the register to the memory, and perform an eye diagram test after the refresh is completed.

In order to use the new register data for eye-diagram testing, the electronic device operates with the data in the memory, so after the register data in the target file is read into the register, the register data needs to be refreshed into the memory. This embodiment does not limit the specific manner of refreshing the register data to the memory. For example, for display devices such as VR devices and AR devices, the register data may be refreshed to the memory by turning off the display screen. After the new register data is flushed to the memory, the electronic device can use the new register data to perform a new eye pattern test. No software compilation is required in the two eye diagram tests, nor is the need to restart the electronic device, thus reducing the time required for software compilation and restarting, and improving the efficiency of the eye diagram test.

By applying the eye diagram testing method provided by the embodiments of the present application, target data is acquired from the outside world, and the target data is written into a target file. Since the register can also read the data in the file when the device is working, the register data in the target file can be read into the register. The target data is transferred through the target file, that is, the data is first written to the target file and then read to the register, so that the data in the register can be updated when the device is working, and the data in the register can be released by reading the target file. The restriction that data cannot be directly modified. After the register data in the register is refreshed to the memory, the device can use the new data for eye diagram testing. The method can reduce the number of software modifications and compilations and the number of restarts of the device, update parameters in real time without shutting down the device, reduce the time required for eye diagram testing, improve the testing efficiency, and solve the testing time existing in related technologies. longer, less efficient problems.

Based on the foregoing embodiments, this embodiment will specifically describe several steps in the foregoing embodiments. Wherein, step S101 may include:

Step 11: Use the ADB port to acquire target data and corresponding pointing information.

Step 12: Determine the register data to be updated of the target file according to the pointing information, and use the target data to update the register data to be updated.

In this embodiment, the target data can be acquired through the ADB port. It should be noted that the target data is not full and complete register data, that is, not data used to cover all the data in the target file. Therefore, in order to accurately write the target data to the target file, the pointing information corresponding to the target data can also be obtained through the ADB port. The target data and the pointing information can be acquired at the same time, or the target data and the pointing information can be acquired separately in two times, and the acquisition of the target data and the pointing information can be recorded by using the corresponding flag bits. Modified to 1 after all acquisitions. After it is determined that the target data and the pointing information are acquired, the register data to be updated is determined in the target file according to the pointing information, and the register data to be updated is updated by using the target data. In one embodiment, the register data to be updated is all data corresponding to a certain register, and in another embodiment, the register data to be updated is the part of the register data corresponding to a certain register that needs to be replaced. After the register data to be updated is determined, it can be replaced with the target data. Specifically, the original data can be deleted before the target data is written, so that the unwritten part can be determined when the write failure needs to be rewritten, so that the unwritten part of the target data can be directly written. In another implementation manner, the target data can be directly used to overwrite and update the register data to be updated.

By acquiring the pointing information when acquiring the target data and writing the target data according to the pointing information, the volume of the target data can be reduced, and it is not necessary to send the full amount of data corresponding to the target file in each transmission, thereby avoiding waste of communication resources.

Based on the above embodiment, if register data corresponding to multiple registers is recorded in the target file, step S102 may include:

Step 21: Acquire multiple register data and corresponding data identifiers from the target file.

Step 22: Determine the target register corresponding to each register data according to the data identifier.

Step 23: Write each register data into the corresponding target register.

Since the number of registers is multiple, the target file stores register data corresponding to multiple registers. In order to prevent the electronic device from working abnormally due to register data reading errors, in this embodiment, a corresponding data identifier is set for each register, and the The data identification corresponds to the register data. The data identifier may specifically be information such as a data number, a register number, a location in the target file, etc., which can play an identifier role, and the specific content can be set as required. When the register data is read to the register, the corresponding relationship of register data-data identification-register can be used to determine the target register corresponding to each register data according to the data identification, and after the determination, the register data is written to the corresponding target register middle.

Further, since the target data may be incomplete data, after writing the target data to the target file, only part of the data in the target file has changed, while some data has not changed. As a result, some register data in the object file may have changed, while other register data has not changed. Therefore, before writing each of the register data into the corresponding target register, it may further include:

Step 31: Determine whether the data of each register has changed.

Step 32: If there is a change, the register data is determined as the target register data.

Correspondingly, the data of each register is written into the corresponding target register, that is, step 23 may include:

Step 33: Write the target register data into the corresponding target register.

After determining the target register corresponding to each register, it can be determined whether the data of each register has changed, that is, which register data has been modified by the target data written this time. If a register data has changed, it must be read to the register to modify the data in the register, so it can be determined as the target register data. If the data of a certain register has not changed, no matter whether it is read to the corresponding target register or not, the data in the target register will not change. Therefore, in this embodiment, the register data that has not changed may not be read. Fetch to the corresponding destination register in order to reduce the time required for data read.

Based on the above embodiment, step 103 may include:

Step 41: Turn off the display screen and turn it back on to refresh the register data to the memory when the display screen is turned on.

In this embodiment, the electronic device is specifically a display device with a display screen, such as a wearable device such as a VR device or an AR device, or a non-wearable device with a display screen such as a computer. When the register data in the register is refreshed to the memory, the data in the memory can be cleared by closing the display screen, and then the display screen can be turned on again. When the display screen is turned on again, the data in the register will be read into the memory to support the normal operation of the electronic device. Therefore, by turning off the display screen and turning it on again, the data is refreshed into the memory without any need for the electronic device. Do a restart.

Based on the above embodiment, in this embodiment, the target data can be updated, so as to reduce the time required for manually inputting the target data, and further improve the efficiency of the eye pattern test. Please refer to FIG. 2, which is a flowchart of a specific target data update process provided by the embodiment of the present application, which specifically includes:

S201: Obtain the data range corresponding to the register data.

It can be understood that each register has a corresponding value range. For example, for the Qualcomm chip sxr2130, its display mipi (Mobile Industry Processor Interface, mobile industry processor interface, display mipi is the display mobile industry processor interface) adjustable registers are 0x0ae94420 register and 0x0ae96420 register, among which, 0x0ae94420 register The value range (that is, the data range) is 0x00 to 0x3f, which needs to be within this range when using the target data to set the register data in the 0x0ae94420 register. Therefore, acquiring the data range corresponding to the register data can define the update range for the subsequent update of the target data. It should be noted that, this implementation does not limit the specific execution timing of S201, and it may be executed before the target data is updated.

S202: Obtain an eye diagram test result.

The eye diagram test result may reflect the test result when the current register data is used to perform the eye diagram test, and its specific form is not limited, for example, it may be 0 or 1, or it may be a score, such as 60 points. The eye diagram test results can be divided into pass and fail. Pass means that the current register data can make the electronic device work normally and meet the requirements; Fail means that the electronic device cannot work normally with the current register data and does not meet the requirements.

S203: Determine whether the eye diagram test result is passed.

It can be understood that there may be various ways to determine whether the eye diagram test result is passed, and the determination method may be different according to the specific form of the eye diagram test result. For example, when the eye diagram test result is 0 or 1, 1 can be determined as pass. Or when the eye diagram test result is a score, it can be determined as a pass when the score is greater than 60 points. If the eye diagram test result is passed, the step S205 may be entered, and if the eye diagram test result is not passed, the step S204 may be entered.

S204: Update the target data according to the data range, and write the updated target data into the target file.

If the eye diagram test result is failed, it means that the current register data cannot make the electronic device work normally, so the target data can be updated according to the data range, that is, new data is selected as the target data in the target data range, and the target data After the data is updated, it is written to the target file, so that the updated target data can be read into the register through the target file. This embodiment does not limit the specific manner of updating. For example, a preset update sequence of updating from large to small or from small to large can be set, and data is determined within the data range according to the preset update sequence, and the determined data is determined. is the updated target data.

Further, in a possible implementation manner, the number of registers is multiple, so when updating target data, only target data corresponding to some registers may be updated. For example, only register data corresponding to one register can be updated at a time, so as to perform eye-diagram test on combinations of various register data to ensure the comprehensiveness of the test. Step S204 may include:

Step 51: Determine whether the register corresponding to the target data needs to be updated.

Step 52: If it needs to be updated, update the target data according to the data range and according to the preset update sequence.

Before updating the target data, it can be judged whether the corresponding register needs to be updated. For example, an update flag bit can be set to specify the update status of each register whether it needs to be updated. If it is determined that the target register needs to be updated, the target data can be updated according to the data range and in a preset update sequence. For example, for the Qualcomm platform sxr2130, the adjustable registers are the 0x0ae94420 register and the 0x0ae96420 register, where the value range (that is, the data range) of the 0x0ae94420 register is 0x00 to 0x3f. The update flag bit corresponding to the 0x0ae94420 register is 1, indicating that it needs to be updated, and the update flag bit corresponding to the 0x0ae96420 register is 0, indicating that it does not need to be updated. In this case, if the current value of the 0x0ae94420 register is 0x00, and the preset update sequence is from small to large, it can be determined that the value of the updated register is 0x01, so 0x01 can be used to update the target data.

S205: preset operation.

This embodiment does not limit the specific execution content after the eye diagram test result, that is, does not limit the specific content of the preset operation. For example, it can be no operation, that is, no operation is performed, or the target data can be updated so that the eye diagram can continue to be performed. Figure test, and then filter out the best register data to make the electronic device work in the best state.
