Description

Method and device for initializing USID and electronic equipment

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for initializing a USID, and an electronic device.

Background

As the complexity of radio frequency devices is increasing, radio frequency devices controlled by General-purpose input/output (GPIO) are gradually eliminated, and radio frequency devices controlled by Mobile Industry Processor Interfaces (MIPI) are widely used.

In a practical application scenario, for better control and collision avoidance, an operation of rewriting an identity identification code (USID) is generally performed on each MIPI device. The operation of rewriting the USID is generally divided into two steps:

1) Matching a Product identification code (Product ID, PID), a Manufacturer ID (MID) and a device delivery value;

2) The rewrite operation of the USID is completed by the register.

In the practical use process of the MIPI control radio frequency device, the USID rewriting of the initialization register is frequently operated, and the USID is possibly changed by mistake. In addition, in the actual use process of the radio frequency device, problems such as poor quality of MIPI signals, wrong identification of the device itself, interference and the like also exist, and the USID of the radio frequency device may be wrongly written. And the error writing of the USID can cause the device to be hung up, the restart is invalid, and the battery can be recovered only by shutting down/pulling out the battery.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.

Aiming at the problem that the USID is wrongly written in the prior art, the application provides a method for initializing the USID. Specifically, the rewritten value of the USID device may be stored in the radio frequency driver configuration file (MIPI device configuration information), and if the value of the USID device is different from the rewritten value of the USID device stored in the radio frequency driver configuration file, it indicates that the USID is wrongly written. Therefore, before initializing the device MIPI register each time, the rewrite value of the USID device stored in the radio frequency drive configuration file is read, the USID device is corrected based on the read rewrite value, and the wrongly written USID device is rewritten to a correct value (rewrite value). Therefore, the problem of device hang-up possibly caused by error writing of the USID can be effectively avoided.

Fig. 1 is a flowchart illustrating a method for initializing a USID according to an embodiment of the present application. As shown in fig. 1:

step 110, before initializing the MIPI register of the device each time, reading a radio frequency drive configuration file and obtaining a rewriting value of the USID device;

step 120, the value of the misidentified USID device is rewritten to a rewritten value.

Specifically, in an actual application scenario, the possibility of USID is limited, and the USID generally has 0 to F16 values. Thus, in one implementation of step 120, instead of determining whether there is an erroneous write, and not confirming the erroneously written USID device, the values of all USID devices are rewritten to the rewritten values of the USID devices stored in the rf drive profile. In this way, it is ensured that the USID device value must be the correct overwrite value recorded in the rf drive profile.

Further, in one implementation manner of step 120, it is first determined whether the value of the USID device has been wrongly written, and if so, the value of the USID device that has been wrongly written is rewritten to a rewritten value; if no error writing exists, the correction operation of the value of the USID device is not needed, so that the writing frequency of the USID device can be reduced, and the device consumption is reduced.

Further, in an actual application scenario, there is a corresponding relationship between the values of the USID device and the PID and MID of the USID device, which are recorded in the rf driver configuration file. That is, if the values of the USID device's PID, MID, and USID device are consistent with those recorded in the RF driver configuration file, then an indication is made that there is no miswrite. Therefore, in an embodiment of the present application, the values of PID and MID corresponding to the rewritten value of the USID device are read from the rf driver configuration file, and if the value of the USID device is the value of PID and MID of the USID device of the rewritten value and the value of PID and MID corresponding to the rewritten value of the USID device recorded in the rf driver configuration file, the USID device is not wrongly written. On the contrary, if the value of the USID device is the PID and MID values of the USID device with the rewritten value and is not the PID and MID values corresponding to the rewritten value of the USID device recorded in the rf driver configuration file, the USID device has an error writing. Or if the PID and MID values are failed to be read for the USID device with the USID device value as the rewriting value, the USID device is also indicated to have error writing.

Specifically, fig. 2 is a flowchart illustrating a method for initializing a USID according to an embodiment of the present application. As shown in fig. 2:

step 210, before initializing the device MIPI register each time, reading the radio frequency drive configuration file, and obtaining the rewritten value (N) of the USID device, and the PID value (PID _ Original) and the MID value (MID _ Original) corresponding to the rewritten value (N);

step 220, reading a PID value (PID _ Read) and an MID value (MID _ Read) for the USID N device with the value of the USID device being N;

step 221, judging whether reading the PID value (PID _ Read) and the MID value (MID _ Read) is successful;

if the reading is successful, go to step 230, determine whether PID _ origin and MID _ origin are consistent with PID _ Read and MID _ Read;

if the USID device is consistent (PID _ Original is equal to PID _ Read, and MID _ Original is equal to MID _ Read), the USID device is not wrongly written, the value of the USID N device is kept unchanged, and the initialization process is finished.

If PID _ Original and MID _ Original are not consistent with PID _ Read and MID _ Read (PID _ Original is not equal to PID _ Read, and/or MID _ Original is not equal to MID _ Read) in step 230, indicating that there is an error write to the USID device, step 240 is performed to rewrite the values of the USID devices with PID value and MID value as PID _ Original and MID _ Original to a rewritten value N.

Further, if the reading of the PID value (PID _ Read) and the MID value (MID _ Read) fails, it also indicates that the USID device has an error write, and step 240 is performed.

Further, the possibility of USID is limited, and the USID generally has values of 0 to F16. Thus, in one implementation of step 240, the erroneously written USID devices are not confirmed, but rather the values of all USID devices are rewritten to the rewritten value N of the USID devices stored in the rf drive profile. In this way it is ensured that the value of the USID device must be the correct overwrite value recorded in the rf drive profile.

Further, in another implementation of step 240, the erroneously written USID device (the USID device whose PID and MID values are PID and MID original values) is first identified, and then the value of the erroneously written USID device is rewritten to the rewritten value N. Therefore, the rewriting operation can be more pertinent, and the number of the rewritten USID devices is reduced.

Specifically, fig. 3 is a flowchart illustrating a part of a method for initializing a USID according to an embodiment of the present application. In one implementation of step 240, as shown in FIG. 3:

step 310, searching for a USID M device, wherein the PID value and the MID value of the USID M device are the same as the PID _ Original and the MID _ Original;

step 320, the value of the USID M device is rewritten to a rewritten value N.

Specifically, in an implementation manner of step 310, based on a preset value logic, PID values and MID values of all USID devices are read and determined one by one to search the USID M device.

For example, PID value and MID value reading judgment is performed one by one for all USID devices one by one according to the value of the USID device to search the USID M device.

For example, assume that the possible values of USID are 0 to F16 values, and the PID and MID values of USID 5 devices are the same as PID _ Original and MID _ Original.

The PID value and MID value are first read for the USID 0 device.

The PID value and MID value of the USID 0 device are not consistent with PID _ origin and MID _ origin, or if the PID value and MID value are read from the USID 0 device, the PID value and MID value are read from the USID 1 device.

The PID value and MID value of the USID 1 device are not consistent with PID _ origin and MID _ origin, or if the reading of PID value and MID value to the USID 1 device fails, the PID value and MID value are read to the USID 2 device.

By analogy, until after reading the PID and MID values for the USID 5 device, the PID and MID values of the USID 5 device are confirmed to be the same as PID _ Original and MID _ Original. The USID 5 device is the final search result USID M device.

Further, in the scheme of searching all USID devices one by one according to the value of the USID device, assuming that N is smaller than M, in step 130, in the case of confirming the USID M device, the USID N device is read and judged once for the PID value and the MID value, and in

steps

220, 221 and 230, the USID N device is read and judged once for the PID value and the MID value. Therefore, in order to avoid repeatedly performing reading and judgment of the PID value and the MID value, in an implementation manner of step 310, the USID N device is used as an initial device, USID devices arranged behind the USID N device are searched one by one according to the value of the USID device, when the search target value is larger than the maximum value of the USID device, the USID 0 device is returned, and the USID 0 device and the USID devices arranged behind the USID 0 device are searched one by one according to the value of the USID device.

For example, assume that the possible values of USID are 0 to F16 values, the PID value and MID value of the USID 9 device are the same as PID _ Original and MID _ Original, and the overwrite value recorded on the rf drive profile is 4.

The PID value and the MID value are first read for the USID 5 device (4+1).

The PID value and MID value of the USID 5 device are not consistent with PID _ origin and MID _ origin, or if reading PID value and MID value of the USID 5 device fails, the PID value and MID value of the USID 6 device are read.

The PID value and MID value of the USID 6 device are not consistent with PID _ origin and MID _ origin, or if reading PID value and MID value of the USID 6 device fails, PID value and MID value are read from the USID 7 device.

By analogy, after reading the PID value and the MID value of the USID 9 device, the PID value and the MID value of the USID 9 device are confirmed to be the same as the PID _ Original and the MID _ Original. The USID 9 device is the final search result USID M device.

For another example, assume that the possible values of USID are 0 to F16 values, PID values and MID values of USID 9 devices are the same as PID _ Original and MID _ Original, and the rewritten value recorded on the rf drive profile is E.

The PID value and the MID value (F + 1) are first read for the USID F device.

The PID value and MID value of the USID F device are not consistent with PID _ origin and MID _ origin, or if the reading of PID value and MID value of the USID F device fails, the PID value and MID value of the USID 0 device are read.

The PID and MID values of the USID 0 device are not consistent with PID _ Original and MID _ Original, or if the PID and MID values are failed to be read from the USID 0 device, the PID and MID values are read from the USID 1 device.

In one implementation of step 310, USID devices are searched one by one in a remainder fashion to confirm USID M devices. Specifically, fig. 4 is a flowchart illustrating a part of a method for initializing a USID according to an embodiment of the present application. In one implementation of step 310, as shown in FIG. 4:

step 400, taking N as an initial value;

step 410, adding 1 to the initial value, and then taking the remainder (Mod (N + +, m)) from the initial value to the total possible value of the USID (for example, 0 to F16 values) to obtain the retrieval value, where the Mod (N + +, m) marks the remainder obtained by taking the remainder from N + + to m, and m is the total possible value of the USID;

step 420, reading the PID value and the MID value of the USID device with the USID device value as the retrieval value (Mod (N + +, m)) to obtain a PID read value and a MID read value;

step 430, judging whether reading the PID value and the MID value is successful;

step 440, when reading the PID value and the MID value is successful, determining whether the PID read value and the MID read value obtained in step 420 are the same as PID _ Original and MID _ Original;

step 450, when the PID read value obtained in step 420 is different from the PID original value and/or the MID read value obtained in step 420 is different from the MID original value, taking the current retrieval value as the initial value when step 410 is executed next time, and returning to step 410;

and step 460, when the PID read value obtained in step 420 is the same as the PID original value and/or the MID read value obtained in step 420 is the same as the MID original value, determining that the value of M is the retrieval value obtained in the last execution of step 410, thereby confirming the final search result USID M device.

Further, in the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by an accessing party. A digital device is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Furthermore, nowadays, instead of manually manufacturing an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as ABEL (Advanced Boolean Expression Language), AHDL (alternate Hardware Description Language), traffic, CUPL (core universal Programming Language), HDCal, jhddl (Java Hardware Description Language), lava, lola, HDL, PALASM, rhyd (Hardware Description Language), and vhigh-Language (Hardware Description Language), which is currently used in most popular applications. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.

Therefore, according to the method of the present application, the present application further proposes an apparatus for initializing a USID, the apparatus comprising:

reading a PID value and an MID value corresponding to the rewritten value in the radio frequency drive configuration file to obtain a PID original value and an MID original value; reading a PID value and an MID value for a first USID device of which the value of the USID device is the rewritten value, and acquiring a first PID read value and a first MID read value when reading the PID value and the MID value successfully; rewriting PID values and MID values as USID device values of the PID original values and the MID original values as the rewritten values when the first PID read value is different from the PID original value and/or the first MID read value is different from the MID original value.

2. The method according to claim 1, wherein in the reading of the PID value and the MID value by the first USID device whose value to the USID device is the rewritten value, when reading of the PID value and the MID value fails, the values of the USID device whose values are the PID original value and the MID original value are rewritten to the rewritten value.

3. The method of claim 1 or 2, wherein rewriting the value of the misidentified USID device to the rewritten value further comprises:

4. The method as claimed in claim 1 or 2, wherein the overwriting of the PID value and MID value as values of USID devices of the PID original value and MID original value as the overwritten values when the first PID read value is different from the PID original value and/or the first MID read value is different from the MID original value comprises:

the values of all USID devices are rewritten to the rewritten value.

5. The method according to claim 1 or 2, wherein the overwriting the PID value and the MID value as values of USID devices of the PID original value and the MID original value as the overwritten values when the first PID read value is different from the PID original value and/or the first MID read value is different from the MID original value comprises:

searching a second USID device, wherein the PID value and the MID value of the second USID device are the same as the PID original value and the MID original value;

rewriting the value of the second USID device to the rewritten value.

6. An apparatus for initializing a USID, comprising:

a rewrite module for rewriting a value of an erroneously written USID device to the rewritten value, comprising:

reading a PID value and an MID value corresponding to the rewritten value in the radio frequency drive configuration file to obtain a PID original value and an MID original value; reading a PID value and an MID value for a first USID device of which the value of the USID device is the rewritten value, and acquiring a first PID read value and a first MID read value when reading the PID value and the MID value successfully; rewriting PID and MID values as the values of the USID devices of the PID original value and the MID original value as the rewritten values when the first PID read value is different from the PID original value and/or the first MID read value is different from the MID original value.

7. An electronic device, characterized in that the electronic device comprises a memory for storing computer program instructions and a processor for executing the program instructions, wherein the computer program instructions, when executed by the processor, trigger the electronic device to perform the method steps of any of claims 1-5.
