Example 1
The embodiment provides a data burning method, which can be suitable for the upgrading process of various terminal devices such as a television, and is implemented by software and/or hardware, referring to fig. 1, and the method comprises the following steps:
S110, acquiring a burning data packet, wherein the burning data packet is generated by a transmitting end according to the burning data code.
The recording data packet represents a file with a preset format containing recording data, is generated by a transmitting end (an upper computer) according to the recording data, and is transmitted to a terminal serving as a receiving end.
In this embodiment, the program of the terminal is generally divided into two parts, one is MBOOT program (boot program) and the other is the NAND main program. The program MBOOT keeps running in the standby state of the terminal, and the program MBOOT can complete the booting from the standby state to the system start when the terminal starts. In order to shorten the time waiting for the transmission of the recording data packet in the data recording process, a loop (thread) for receiving and processing the data is provided in the MBOOT procedure in this embodiment, so that the terminal can always acquire the recording data packet in the standby state.
Specifically, in this embodiment, the terminal keeps MBOOT the program running in the standby state, and a cycle for receiving and processing data is pre-established in the MBOOT program, so that the terminal detects whether the transmitting end transmits the recording data packet at any time in the standby state, and if yes, directly receives the recording data packet.
S120, decoding the recorded data packet to obtain the recorded data, and writing the recorded data into a preset array.
The recording data packet is generated by the transmitting end according to the recording data code, so that the recording data packet can be obtained by corresponding decoding. Since the receiving of the recording data packet and the decoding of the recording data packet are completed in MBOOT, the condition that the terminal is still in the standby state MBOOT and the recording data is decoded is easy to occur, and the terminal is in the standby state and cannot record at this time, so that the recording data needs to be temporarily stored, and the recording data can be used for completing the recording after the terminal is started. Therefore, in this embodiment, a preset array is provided for storing the recording data before recording, and considering that the recording data packet received by one recording may include a plurality of data packets, the preset array may further integrate and store the data in the plurality of data packets to obtain the completed recording data.
Specifically, in this embodiment, in the standby state, after receiving the recording data packet, the loop of receiving and processing data in the MBOOT program decodes the recording data packet according to the preset rule to obtain the recording data, and writes the obtained recording data into the preset array to store until all the recording data packets are received.
S130, reading the burning data from the preset array according to the received burning command, and writing the burning data into a storage device.
After the writing data is stored in the preset array, if the terminal does not receive the writing instruction all the time, the writing data in the array is written into an EEPROM (ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY, electrified erasable programmable read-only memory) serving as a storage device through an I2C bus after the terminal receives the writing instruction, and the writing is completed.
The embodiment provides a data burning method, which comprises the steps that a burning data packet is obtained before a burning instruction is received, the burning data packet is decoded to obtain burning data, the burning data is written into a preset array, the burning data can be quickly read from the preset array after the burning instruction is received, the burning data is written into storage equipment, the burning data packet can be received in a terminal standby state, the time consumption for waiting for the terminal to start and then receive the burning data packet is reduced, the burning efficiency is greatly improved, and the method is convenient and quick.
Example two
The embodiment further explains and supplements part of the procedures of the data burning method based on the first embodiment, for example, when the burning data is written into a preset array, a process of verifying the burning data is further added, and the method specifically comprises the following steps:
Specifically, the data generation of the recording data packet, which is generated by separating the recording data by the transmitting end and further defining the recording data as the data in the preset format, namely, the encoding process of the recording data packet, can be completed by software arranged on the upper computer. For example, the upper computer receives a selection instruction of a user through software, determines a specific file corresponding to the burning data according to the selection instruction of the user, separates the data in the specific file to obtain the burning data, and generates a burning data packet in a preset format according to the preset coding rule (which can be set by itself according to actual conditions) and the burning data code.
More specifically, in general, a serial port tool is used for data transmission during data recording, and depending on the serial port tool, a lot of inconvenience is brought to practical application, so in an embodiment, the invention can further realize the transmission of the recorded data packet through the serial port tool or the TCP/IP simulation tool. The recording data packet is sent to the receiving end by the sending end through a serial port tool or a TCP/IP simulation tool, the serial port tool is used for directly sending the recording data packet to the receiving end, and the TCP/IP simulation tool is used for generating a network data packet according to the recording data packet and sending the network data packet to the receiving end. For transmission by using a TCP/IP simulation tool, a receiving end needs to use a wireshark tool to grasp network data, and can specifically grasp the data by adopting a plaintext mode and an encryption mode, wherein the main difference is whether the transmitted network adopts a password, if the transmitted network does not adopt the password, the transmitted network adopts the plaintext, but the plaintext is easy to intercept, so that a mathematical operation formula can be set at the transmitting end for encryption, and an inverse operation formula can be set at the receiving end for decryption, thereby ensuring the normal operation of the data transmission process.
It will be appreciated that, in general, when the data to be recorded is too large, a plurality of data packets are typically used to divide the data to be recorded into a plurality of transmissions, i.e., the data packets to be recorded include one or more data packets. When the burnt data is transmitted through the network data packets, the problem of sticking the data packets easily occurs in the transmission process of the data packets: the sender integrates smaller data packets, and sends the smaller data packets after reaching a certain data length, or the receiver does not know the length of the data to be received, and then sends the smaller data packets to the upper layer after reaching a certain number of data packets, so that a plurality of commands are sent, and the commands are not returned, or a plurality of commands are sent, and the results of the previous commands are returned, so that the command execution is asynchronous. Therefore, in this embodiment, when the recording data packet is generated according to the preset rule encoding, the recording data packet includes one or more data packets, each data packet includes guide information and recording data segments, the guide information includes one or more of a guide code, a total length, a command code, a data packet number, a total number of data packets, and a data packet verification parameter, and the recording data includes one or more recording data segments. Illustratively, a packet is defined as "5A 0C 83 01 01 00 1A 9A E3 4C 02 D0", which is interpreted from left to right as: 5A denotes a boot code, 0C denotes a total length, 83 denotes a command code, the first 01 denotes a packet number, the second 01 denotes a total number of packets corresponding to the recorded data, "00 1A 9A E3 4C 02" denotes one or all of the recorded data (in this example, all of the data), and D0 denotes a recording verification parameter.
As shown in fig. 2, the process of decoding the burned data packet, i.e. step S120 includes steps S121-123:
s121, determining one or more data packets corresponding to the burning data according to the guiding information.
The recording data is obtained according to the recording data packet, that is, the recording data packet is decoded, and the decoding process corresponds to the encoding, that is, the position of the recording data in the recording data packet, for example, the start bit of the recording data, is actually determined. According to the first embodiment, one or more data packets may exist in the recording data packet, and different processing methods are required, so that the data packet corresponding to the recording data needs to be determined first, specifically, whether all the data packets are received is determined according to the data packet number and the total number of the data packets in the guiding information, so as to avoid incomplete recording data finally obtained.
S122, decoding the one or more data packets to obtain one or more recorded data segments, wherein each data packet number corresponds to one recorded data segment.
And S123, sequentially writing the corresponding burnt data segments into a preset array according to the data packet numbers to obtain burnt data.
When writing the writing data into the preset array, it is required to ensure that a complete writing data is obtained after the writing is completed. For the recorded data sent by one data packet, directly decoding after receiving the recorded data packet to obtain recorded data (the recorded data segment is understood to be the complete recorded data herein), and writing the recorded data into a preset array; and when the burning data sent by the plurality of data packets is received, determining the corresponding plurality of data packets according to the data packet numbers and the total number of the data packets, decoding each data packet to obtain a corresponding plurality of burning data segments, writing the burning data segments into a preset array according to the data packet numbers, and recovering to obtain the complete burning data.
The embodiment further provides a process of completing the burning according to the burning command and verifying whether the burning is successful:
Specifically, the writing instruction includes an effective data length, where the effective data length is used to determine a portion of data actually used for writing in the writing data, as shown in fig. 3, and writing the writing data into the storage device specifically includes steps S131-132:
s131, determining the effective data in the burning data from a preset array according to the effective data length.
S132, reading the effective data, and writing the effective data into a storage device.
The writing mainly writes effective data into the storage device, and the writing data may include a lot of data, and only a part of the effective data may be needed in a one-time writing process, which is specifically determined by the writing instruction. After receiving the burning command, the terminal analyzes the burning command to obtain an effective data length, accurately finds effective data stored in a preset array according to the effective data length, wherein the effective data can be partial data or all data in the burning data, writes the effective data into the storage device, and finishes burning after all writing of the effective data is finished.
More specifically, the writing instruction further includes a writing verification parameter, as shown in fig. 4, after writing the writing data into the storage device, i.e. step S130, including steps S140-160:
s140, reading the effective data written in the storage equipment, wherein the effective data comprises data packet verification parameters.
And S150, comparing the burning verification parameters according to the data packet verification parameters to verify whether the writing is successful, and if so, deleting the burning data in the preset array.
And S160, if not, re-reading the effective data, and writing the effective data into the storage device.
Verifying whether the burn is completed correctly is to verify whether the valid data written to the storage device is accurate. Considering that there may be transmission errors in the data transmission process, in this embodiment, a recording check parameter is added to the recording instruction, where the recording check parameter is the same as a data packet check parameter sent by the sending end. During verification, the terminal reads the data packet verification parameters in the effective data in the storage equipment, if the data packet verification parameters are consistent with the recording verification parameters, the transmission process is normal, the recording process is normal, and at the moment, the recording data in the preset array can be deleted to finish recording; if the data packet verification parameters are inconsistent, the valid data in the preset array needs to be read again and written into the storage device again, and further, in some cases, the sending end needs to resend the burnt data packet (verifying whether the data packet verification parameters in the preset array are the same as the burnt verification parameters, and if the data packet verification parameters are not the same, the sending end needs to resend the burnt data packet).
The specific format of the writing command corresponds to the writing data packet, and illustratively, corresponding to the writing data packet example, a writing command is "5A 08 8D 0006 2D 83 A5", where 5A represents the corresponding guide code, 08 represents the total length, 8D represents the writing command, "00 06" represents the number of valid data, "2D represents the valid data checksum", 83 represents the command code, and A5 represents the writing checksum.
More specifically, in one embodiment, as shown in FIG. 5, after writing the burned data into the storage device, the data reading process steps S170-180 are further included:
s170, receiving a data reading instruction, wherein the data reading instruction comprises a data address and a data size.
The data reading instruction is used for completing the reading and writing of the bottom layer based on the I2C bus and reading the burnt data which is already written into the storage device, wherein the data address and the data size are used for finding specific data content.
S180, reading data in the storage device through the I2C bus according to the data address and the data size, and storing the data into a preset array.
After receiving the data reading instruction, the terminal finds out which address the data to be read starts from according to the data address, determines the data of which size the data to be read is according to the data size, so as to find out the data to be read, stores the data to be read into a preset array, and can directly call for display or other functions to complete the reading of the data.
The data burning method provided in this embodiment further provides specific formats of the data packet and the burning command based on the first embodiment, and provides a process of writing the burning data into the preset array and a process of verifying whether the data burning is completed correctly based on the specific formats, so that stable data burning is further ensured.
