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 invention.
At present, firmware burning of the eMMC is finished by the MCU, and the MCU is occupied when executing one-by-one instructions to finish the firmware burning, so that other actions cannot be executed, and the resource occupation is serious. Meanwhile, the function of the MCU in the whole burning process is very closed, which is not beneficial to tracking and debugging, and the flexibility is not high. In the application, the MCU only sends a burning command, and the whole firmware burning process is finished independently of an eMMC command analysis module and an eMMC action module outside the MCU, so that MCU resources are not greatly occupied; meanwhile, the eMMC configuration command can be flexibly configured in the first memory, so that the whole firmware burning system is more flexible and is convenient to debug.

the second memory 2 is used for storing the data of the firmware to be burned;
the eMMC command analysis module 3 is used for analyzing an eMMC configuration command when receiving a burning instruction of the MCU so as to trigger the eMMC action module 4;
and the eMMC action module 4 is used for reading the firmware data to be burned in the second memory 2 and writing the firmware data into the eMMC equipment according to the analyzed eMMC configuration command.
It is understood that the first Memory 1 is specifically an SRAM (Static Random Access Memory) that receives an eMMC configuration command through an I2C (Inter-Integrated Circuit) interface; the second memory 2 is specifically an SRAM which receives firmware data to be burned through an I2C interface, the first memory 1 and the second memory 2 can be collectively called a burning SRAM, and the upper computer can flexibly adjust command parameters of an eMMC configuration command through an I2C interface, so that the whole firmware burning system in the embodiment can be flexibly configured and is convenient to debug; the eMMC command parsing module 3 and the eMMC action module 4 are both hardware modules located in the eMMC master control, and since the processing speed of the hardware is faster than that of the MCU, the burning efficiency of this embodiment is higher.
The eMMC command analysis module reads an eMMC configuration command in the first memory 1 after receiving the burning instruction, and mainly analyzes the eMMC configuration command through a bit in the eMMC configuration command, so that the eMMC configuration command is stored in the first memory 1 according to a certain preset format, for example, a preset format of the configuration command shown in fig. 2 is required, wherein 48 bits of each eMMC configuration command, a start bit is 0, a transmission bit indicates a transmission direction, and the configuration is 1, and indicates that the configuration command is sent to eMMC equipment by eMMC master control; the command index represents a command index, and the value is between 0 and 63; an argument represents a parameter of the configuration command; CRC7 is the CRC protection for the configuration command; end bit indicates the end of the configure command, the bit being 1. Therefore, the size of the SRAM corresponding to the first memory 1 can be designed to be 64 × 48. Similarly, the SRAM size for the second memory is typically 256 × 32.
Generally, the eMMC command parsing module 3 is specifically configured to: when a burning instruction is received, polling whether an eMMC configuration command is stored in the first memory 1; if yes, the eMMC configuration command is analyzed so as to execute the following steps:
initializing an eMMC device;
erasing a target area in the eMMC equipment;
and writing all the firmware data to be burned in the second memory 2 into the target area through the eMMC action module 4.
It is to be appreciated that eMMC configuration commands generally include: the eMMC command parsing module 3 generally executes eMMC configuration commands in a specific command order to burn firmware into the eMMC device, so that the following eMMC configuration commands are often sequentially stored in the first memory 1: CMD0, CMD1, CMD2, CMD3, CMD6, CMD35, CMD36, CMD38, and CMD24 or CMD 25.
The eMMC command analysis module 3 analyzes the eMMC configuration commands, wherein the CMD0 is a reset command and is used for resetting the eMMC equipment so that the eMMC equipment enters an idle state; after the eMMC device enters an idle state, initializing the eMMC device by utilizing initialization commands CMD1, CMD2 and CMD 3; selecting an eMMC bus mode and setting an eMMC operation partition by using a region setting command CMD 6; then, the partitions set by CMD6 are erased by area erase commands CMD35, CMD36, CMD 38; finally, a write command CMD24 or CMD25 is sent, and the data in the second memory 2 is written into the eMMC device through the eMMC action module 4.
In the embodiment, the MCU only sends the burning command, and the whole firmware burning process is completed independently of the eMMC command analysis module and the eMMC action module outside the MCU, so that MCU resources are not greatly occupied; meanwhile, the eMMC configuration command can be flexibly configured in the first memory, so that the whole firmware burning system is more flexible and is convenient to debug.
Correspondingly, an embodiment of the present invention further discloses an eMMC-based firmware burning method, which is applied to an eMMC command parsing module, and as shown in fig. 3, the method includes:

It is to be understood that, before parsing the eMMC configuration command stored in the first memory in step S1, the method may further include: polling whether an eMMC configuration command is stored in the first memory; if so, an action of resolving the eMMC configuration command stored in the first memory is performed.
Further, step S2 may specifically include the following steps:
parsing the eMMC configuration command to perform the following steps:
initializing an eMMC device;
erasing a target area in the eMMC equipment;
and writing all the firmware data to be burned in the second memory into the target area through the eMMC action module.
It can be understood that, when a write command is sent once, if the block number specified to be written by the write command is completed but the firmware data to be burned is not completely written, the write command needs to be sent continuously, that is: and continuously sending a write command to the eMMC action module so as to write all the firmware data to be burned into the target area. When all firmware data to be burned is written into the eMMC equipment, the burning is considered to be finished.
Therefore, combining all the above burning steps, a specific firmware burning method is shown in fig. 4:
s11: when a burning instruction of the MCU is received, polling whether an eMMC configuration command is stored in the first memory;
s12: if yes, the eMMC configuration command stored in the first memory is analyzed;
s13: initializing an eMMC device;
s14: erasing a target area in the eMMC equipment;
s15: sending a write command to the eMMC action module to write the firmware data to be burned into a target area;
s16: judging whether the block number specified by the write command is written;
s17: if yes, judging whether the firmware data to be burned is completely written; if yes, the burning is finished, if not, the process goes to step S15.
It is to be understood that when the determination results in steps S11 and S16 are no, the present step is continuously executed until the determination result is yes.
In the embodiment, the MCU only sends the burning command, and the whole firmware burning process is completed independently of the eMMC command analysis module and the eMMC action module outside the MCU, so that MCU resources are not greatly occupied; meanwhile, the eMMC configuration command can be flexibly configured in the first memory, so that the whole firmware burning system is more flexible and is convenient to debug.
