The embedded device may be a composite device that is previously configured by encoding or the like into a mass memory (Mass Storage Class, MSC, also known as mass storage class) and a Virtual serial Port (VCP). The embedded device prototype may be a universal serial bus (Universal Serial Bus, USB) device in particular.

As shown in fig. 1 in detail below, the firmware update method includes the steps of:

and S120, responding to a second information reading instruction initiated by the main equipment to be updated based on the mass storage or the virtual serial port, reading the data to be updated from the target storage memory space, and transmitting the data to be updated to the main equipment to be updated.

The embedded device comprises a file information memory space and/or a target storage memory space, and/or is in communication connection with the target storage device comprising the file information memory space and/or the target storage memory space; the main equipment to be updated is used for updating the data to be updated to the corresponding data area according to the updating configuration information.

As can be seen from the foregoing description, the firmware updating method of the embodiments of the present application is applied to an embedded device, and by configuring the embedded device as a composite device of a mass storage and a virtual serial port in advance, in this way, when a host device to be updated is in communication connection with the embedded device, the host device to be updated may acquire update configuration information in the file information memory space based on the virtual serial port, and the host device to be updated may flexibly acquire data to be updated stored in the target storage memory space based on the mass storage or the virtual serial port, so as to update the data to be updated into a corresponding data area in the host device to be updated according to the acquired update configuration information.

In summary, according to the firmware updating method provided by the embodiment of the application, the firmware updating is performed based on the composite device including the mass storage and the virtual serial port, and the main device to be updated can flexibly acquire the data to be updated and the update configuration file without introducing additional device devices or other communication protocols in the firmware updating process, so that the firmware updating difficulty can be reduced to a certain extent, the overall firmware updating efficiency is improved, and meanwhile, the cost consumed by firmware updating is reduced.

The specific implementation of the steps 110 to 120 will be described in detail below.

In S110, the host device to be updated may be an electronic device such as a mobile terminal, a personal computer (personal computer), or a PC, which is not strictly limited in the embodiment of the present application. In the actual firmware upgrade scenario, the host device to be updated and the embedded device may be connected in communication through a USB data bus or through a slot.

In the specific implementation, under the condition that the main equipment to be updated is in communication connection with the embedded equipment, the main equipment to be updated responds to a first information reading instruction initiated by the main equipment to be updated based on the virtual serial port, reads the update configuration information from the file information memory space, and transmits the update configuration information to the main equipment to be updated. When the update configuration information is transmitted to the main device to be updated, the transmission of the update configuration information from the file information memory space to the main device to be updated can be realized based on the virtual serial port.

According to some embodiments of the present application, more specifically, in connection with an actual firmware upgrade update scenario, at least one of an update data start address, an update data length, and a verification value may be included in the update configuration information.

In S120, in a specific implementation, under a condition that the to-be-updated master device is in communication connection with the embedded device, the embedded device responds to a second information reading instruction initiated by the to-be-updated master device based on the mass storage or the virtual serial port, reads to-be-updated data from the target storage memory space, and transmits the to-be-updated data to the to-be-updated master device. The data to be updated may be, for example, a bin file.

The embedded device comprises a file information memory space and/or a target storage memory space, and/or is in communication connection with the target storage device comprising the file information memory space and/or the target storage memory space.

For example, the embedded device may use a portion of its own memory space as the file information memory space. And, in view of the fact that the data to be updated is generally large in data size, in order to facilitate effective capacity expansion, the above target storage memory space may be a memory space in a target storage device, where the target storage device may be, for example, an SPI (serial peripheral interface ) Flash (Flash memory), specifically may be, for example, an SPI norflash, etc., and the present example is not limited strictly herein.

After the main device to be updated obtains the update configuration information and the data to be updated through the first information reading instruction and the second information reading instruction, the main device to be updated can be used for updating the data to be updated to the corresponding data area according to the update configuration information.

For example, in the case that the update configuration information includes the update data start address, the update data length, and the check value, the master device to be updated may be the content of the update data start address and the length of the update data length by erasing the memory start address, and then write the data to be updated into the erased data area, so that the data update is efficiently implemented.

It should be noted that, in the embodiment of the present application, the step 110 and the step 120 are not strictly executed in sequence, and the step 110 may precede or be later than the step 120, or the step 110 and the step 120 are executed simultaneously, which may be flexibly set according to the actual configuration,

According to some embodiments of the present application, optionally, in order to more reasonably implement writing of relevant update configuration information and update configuration information in the embedded device, before responding to a first information reading instruction initiated by the to-be-updated master device based on the virtual serial port, and before responding to a second information reading instruction initiated by the to-be-updated master device based on the mass storage or the virtual serial port, the firmware updating method may further include:

Under the condition that the embedded equipment is in communication connection with the terminal equipment, the updating configuration information is written into the file information memory space and the data to be updated is written into the target storage memory space in response to a first data writing instruction sent by the terminal equipment based on the virtual serial port.

In particular, for example, the embedded device may be inserted into a USB interface of the terminal device, for example, a PC, in advance, so as to implement a communication connection between the embedded device and the terminal device.

In this case, the virtual serial port tool (for example, secure crt) may be invoked in the terminal device, and the corresponding developer may send the first data writing instruction to the embedded device based on the virtual serial port tool, so that the read, write, erase, etc. on the file information memory space may be completed, the update configuration information may be written into the file information memory space, and the data to be updated may be written into the target storage memory space.

According to some embodiments of the present application, optionally, for reasons similar to the foregoing embodiments, in order to more reasonably implement writing of relevant update configuration information and update configuration information in the embedded device, in addition to the foregoing virtual serial port implementation data pre-writing, data acquisition may also be implemented by using an MSC configured by the embedded device. Specifically, before the first information reading instruction initiated by the to-be-updated main device based on the virtual serial port is responded, and before the second information reading instruction initiated by the to-be-updated main device based on the mass storage or the virtual serial port is responded, the firmware updating method may further include:

Under the condition that the embedded equipment is in communication connection with the terminal equipment, responding to a file moving request initiated by the terminal equipment based on the mass storage, and moving the target file to a target storage memory space; the target file may include at least data to be updated.

In this embodiment, the embedded device is inserted into the USB interface of the terminal device PC, so as to implement communication connection between the embedded device and the terminal device. Because the embedded device is a composite device of the mass memory MSC and the virtual serial port VCP, the terminal device PC can identify one MSC device (which can be regarded as a U disk) after being connected with the embedded device, so that the target file to be stored in the embedded device can be moved to the MSC device, and the MSC device uses the target memory space to store the target file. The target file may specifically be, for example, a bin file or a hex file, which is not strictly limited in this embodiment, and the target file at least includes the data to be updated.

According to some embodiments of the present application, optionally, considering the requirement of the subsequent master device to be updated for the data to be updated and the update configuration data, and combining the MSC and VCP composite features of the embedded device, where the update configuration information is not included in the above object file, the firmware update method may further include:

And writing the updated configuration information into the file information memory space in response to a second data writing instruction initiated by the terminal equipment based on the virtual serial port.

In particular, when the target file does not include the update configuration information, the corresponding update configuration information needs to be additionally stored in the embedded device. Based on this, in the case that the embedded device is communicatively connected to the terminal device, the terminal device may initiate a second data writing instruction to the embedded device based on the virtual serial port, so that the corresponding update configuration information is written into the file information memory space through the second data writing instruction.

According to some embodiments of the present application, optionally, considering that, in order to facilitate a subsequent implementation of firmware update of the to-be-updated master device, the to-be-updated master device may reasonably and efficiently obtain to-be-updated data and update configuration information, in the case that the above-mentioned target file may include update configuration information, after moving the above-mentioned target file to the target storage memory space, the firmware update method may further include:

analyzing the target file, and extracting to-be-updated data and updated configuration information;

And re-storing the data to be updated in the target storage memory space, and storing the updated configuration information in the file information memory space.

Specifically, for example, if the target file is a hex file including both data to be updated and update configuration information, then the target file stored in the target storage memory space needs to be parsed.

In the specific analysis, the data to be updated and the update configuration information can be respectively extracted by means of field analysis, disassembly and the like. And then, re-storing the data to be updated into the target storage memory space, and storing the updated configuration information into the file information memory space.

In addition, in consideration of reasonable utilization of the target storage memory space, the data to be updated is re-stored in the target storage memory space, the updated configuration information is stored in the file information memory space, and the target file in the target storage memory space can be deleted.

According to some embodiments of the present application, more specifically, in order to more reasonably achieve parsing of the target file, the embedded device may further include a first memory space, where the first memory space is used to store and run bootloader code; before analyzing the target file and extracting the data to be updated and the update configuration information, the firmware update method may further include:

Adding a high-capacity memory file system in a first memory space;

analyzing the target file, and extracting to-be-updated data and update configuration information may include:

analyzing the target file in the target storage memory space by operating the high-capacity storage file system in the first memory space, and extracting to-be-updated data and updated configuration information.

In a specific implementation, in combination with an embedded scenario, a portion of the memory space may be divided into the first memory space in the embedded device, where the first memory space may be used to store and run bootloader code, which is also referred to as bootloader code space. In this embodiment, an MSC file system is added to a bootloader in an embedded device in advance, so as to detect and parse a target file.

Specifically, whether the target file is a compound file including data to be updated and update configuration information is detected by invoking and running the MSC file system. For example, if it is detected that the target file is in the hex file format, it is confirmed that the target file needs to be further parsed. When the specific target file is analyzed, the target file in the target storage memory space can be analyzed by calling and running the corresponding function of the MSC file system, so that the data to be updated and the update configuration information are extracted.

According to some embodiments of the present application, in particular, in combination with the embedded scenario, the composite compatibility of the embedded device with the MSC and the VCP is more reasonably achieved, where the embedded device may further include a second memory space, where the second memory space is used to store and run application code. The second memory space may include a first function code module for implementing a virtual serial port, and a second function code module for implementing a mass storage.

The above-mentioned responding to the first information reading instruction initiated by the to-be-updated master device based on the virtual serial port reads the update configuration information from the file information memory space, and transmits the update configuration information to the to-be-updated master device, which may include:

the method comprises the steps of receiving and responding to a first information reading instruction by controlling and running a first functional code module in a second memory space, reading updated configuration information from a file information memory space, and transmitting the updated configuration information to a main device to be updated;

the above-mentioned responding to the second information reading instruction initiated by the main device to be updated based on the mass storage or the virtual serial port reads the data to be updated from the target storage memory space, and transmits the data to be updated to the main device to be updated, may include:

And the first functional code module or the second functional code module in the second memory space is controlled to be operated so as to receive and respond to the second information reading instruction, read the data to be updated from the target storage memory space, and transmit the data to be updated to the main equipment to be updated.

In order to facilitate a more intuitive understanding of the firmware updating method provided in the above embodiment, the firmware updating method is described in the following in an embodiment of a specific scenario. Referring to fig. 2, fig. 2 is a schematic diagram of a system working frame between a host device to be updated and an embedded device according to an embodiment of the present application.

As shown in fig. 2, the application scenario of the present scenario embodiment may be: the embedded device to be updated (main device to be updated) is in communication connection with the embedded device through a USB data bus so as to update and upgrade the firmware of the embedded device to be updated, wherein the embedded device to be updated can be a USB device, and the embedded device to be updated can be an electronic device such as a PC (personal computer), a tablet and the like.

In this embodiment of the present scenario, before firmware update is performed on the embedded device to be updated, related preparation work needs to be performed, where the preparation work is specifically as follows:

1) The memory in the embedded device is divided into three types of spaces, namely a bootloader code space, an application code space and a file information memory space.

Specifically, the bootloader code space corresponds to the first memory space in the foregoing embodiment, an MSC file system is added in the bootloader, the application code space corresponds to the second memory space in the foregoing embodiment, and the second memory space may include a first function code module for implementing a virtual serial port and a second function code module for implementing a mass memory, so as to facilitate composite compatibility of the embedded device for MSC and VCP. The embedded device is externally connected with a target storage device, the target storage device specifically comprises SPI Nor Flash, and the target storage device comprises the target storage memory space.

2) This embedded device is reset to MSC and VCP. MSC memory can use the goal memory space in SPI Nor Flash;

3) The developer inserts the embedded device into the USB interface of the terminal device PC so as to write the data to be updated and the update configuration information into the embedded device, and the specific writing method is as follows:

method 1: the terminal device PC invokes a virtual serial port tool (e.g., a secure crt) to open, and the developer sends the first data writing instruction to the embedded device based on the virtual serial port tool, so as to complete the operations of reading, writing, erasing, etc. on the file information memory space, write the update configuration information into the file information memory space, and write the data to be updated into the target storage memory space.

Method 2: after the terminal equipment PC is connected with the embedded equipment, the embedded equipment is a composite equipment of a large-capacity memory MSC and a virtual serial port VCP, so that the PC can simultaneously identify the embedded equipment as one MSC equipment (can be regarded as a U disk), a developer can directly move a target file to be stored in the embedded equipment into the MSC equipment through operations such as simple copying and pasting, and the MSC equipment uses the target storage memory space in the SPI Nor Flash to store the target file.

And under the condition that the target file does not comprise the update configuration information, the terminal equipment can continuously initiate a second data writing instruction to the embedded equipment based on the virtual serial port, so that the corresponding update configuration information is written into the file information memory space through the second data writing instruction.

In the case that the update configuration information may be included in the target file, the embedded device may be configured to detect and parse the target file by adding an MSC file system to a bootloader in the embedded device in advance. It is illustratively detected whether the target file is a compound file comprising data to be updated and update configuration information by invoking and running the MSC file system. For example, if it is detected that the target file is in the hex file format, it is confirmed that the target file needs to be further parsed. When the specific target file is analyzed, the target file in the target storage memory space can be analyzed by calling and running the corresponding function of the MSC file system, so that the data to be updated and the update configuration information are extracted. Thus, the data to be updated is restored in the target storage memory space, and the updated configuration information is stored in the file information memory space.

After the data to be updated is written into the target storage memory space through the preparation operation and the update configuration information is stored into the file information memory space, the firmware update flow of the embedded device to be updated is specifically as follows:

1) And the embedded device to be updated (the main device to be updated) is in communication connection with the embedded device, and the main device to be updated can identify the embedded device through bootloader codes.

2) Under the condition that the embedded device is identified as the composite device compatible with the MSC and the VCP, the embedded device to be updated can capture the update configuration information in the file information memory space of the composite device through the VCP, and the update configuration information can comprise an update data starting address, an update data length and a check value.

3) The embedded device to be updated can obtain the data to be updated in the target memory space by reading through MSC or VCP, and the data to be updated can be a bin file.

4) The embedded device to be updated erases the content of the initial address of the data with the length being the length of the updated data, and writes the data to be updated into the erased data area to realize the firmware update.

In summary, according to the firmware updating scheme provided by the embodiment, the firmware is updated based on the composite device including the mass memory and the virtual serial port, and the main device to be updated can flexibly acquire the data to be updated and the update configuration file without introducing additional device devices or other communication protocols in the firmware updating process, so that the firmware updating difficulty can be reduced to a certain extent, the overall firmware updating efficiency is improved, and the cost consumed by firmware updating is reduced.
