2. Description of the Related Art
The System firmware (such as ROM) refers to a solidified software which writes a certain program in a flash memory in a spécifie hardware system. The firmware of a mobile is équivalent to the system of a mobile, and refreshing the firmware is équivalent to refreshing the system.
The system program generates the mirror of the system firstly, then the mirror of the system is transmitted to the memory of the device to programme into the memory of the device. To meet the requirement of adding new data during the process of using, the size of the mirror of the system generated by the program “system” is much larger than the size of the program “system”. For example, a system program with a size of 500M (Mbit) may results in a mirror of the System “system.img” with a size of IG (Gbit) or even more.

DETAILED DESCRIPTIONS
By referring to the detailed description for the unlimited embodiments with the accompanying drawings, the invention and the feature, outline and advantage thereof will be more obvious. The same signs in the drawings indicate the same part. The drawings are not drawn in proportion and they just intend to show the principle of the invention.
To address the problem which the programming speed of a system firmware is low and the time of programming is long, the invention provides a method for increase programming speed of a system firmware. The method is implemented by adjusting the size of an intermediate file system, generating a mirror of the system according to the size of the adjusted intermediate file system, transmitting the mirror of the system to the memory and programming the mirror of the system into the flash memory of the device. Thus the size of the mirror of the system is reduced efficiently, the time of making the mirror of the system and transmitting the mirror to the memory is saved, the time of programming the mirror into the flash memory is saved, and the programming speed of the system firmware is increased efficiently. Meanwhile, the time of debugging by the engineer is reduced, the time of hardware manufacturing in the assembly line is reduced. The following illustration is further depicted by combining the drawings and the embodiments without being the limit of the invention. '
The system firmware is a huge set of files, such as the file of “system.img”, “userdata.img” and “ccache.img” in the Andriod system. The embodiment only describe the file of “system.img”, any modifications of other files in the system according to the principle of the invention fall in the scope of the invention.
Figure 1 shows the procedure schematic view of the method for programming of a system firmware in prior art. For example, there is a “system/” catalog with a size of 500M (Mbit) need to be stored a 500M (Mbit) data. Due to the existence of the file system with a size of 500M, preferably, it generates an intermediate file system with a size of 1024M. The size of the intermediate file system includes the system files and the contained data capacity. Then generate a mirror file “system.img” with a size of 1024M according to the intermediate file system with a size of 1024M, transmit the generated mirror file “system.img” with a size of 1024M to the memory (such as to the memory of the smart device), that is, download IG (Gbit) data to the memory as shown in Figure 1. Finally, program the mirror file “system.img” with a size of IG transmitted to the memory into the flash memory of the smart device. Therefore, the file system with a size of 500M need to generate an intermediate file system including the file system with a size of 500M and required storing data capacity, then generate the mirror of the system according to the size of the intermediate file system. This results in the problems of big size of the mirror of the system and long time of the transmitting and programming. In the prior art, to avoid the problems, the generated intermediate file system is compressed, the compressed files reduces the size of the intermediate file system, then the compressed intermediate file system is transmitted to the memory. After the intermediate file system is decompressed, it is programmed
VS into the flash memory of the device, which is time-consuming. Such device includes a mobile and a tablet computer.
Figure 2 shows the procedure schematic view of the method for increasing programming speed of a system firmware. Firstly, adjust the size of an* intermediate file system, then generate a corresponding mirror of the system according to the size of the adjusted intermediate file system, transmit the generated mirror of the system to the memory, finally program the mirror of the system into the flash memory of the device.
Figure 3 shows the procedure schematic view of the method for programming of a system firmware. For example, there is a flash memory need to be stored a 500M file system with a 500M data.
According to regular method, the file system with a size of 500M generates an intermediate file System with a size of 1024M. Preferably, in file system with a format of “ex3”, execute the command “$resize2fs -M system.img” to adjust the intermediate file system with a size of IG (1204M) into a file system with a size of 500M. In another embodiment, select the format of “ntfs”, when the mirror of the system is located in the device “loopO”, execute the command “ntfsresize -b -s 516M/dev/sdf’ to adjust the intermediate file system with a size of 516M. The format of the mature file system in the prior art are all support adjusting the size of the file system (such as ext3/4, ntfs, fat). Then generate the corresponding mirror of the system according to the size (500M) of the adjusted intermediate file system.. It is noted that the size of the generated mirror of the system is a lightly greater than the size of the intermediate file system, so as to accommodate the files required by the system. Configure the size of the files according to the different files required by the system, but it is limited in 16M, namely, the mirror of the system is no greater than 516M.
Transmit the mirror of the system no greater than 516M to the memory, and program the mirror into the flash memory of the device. Thus the programming of the system firmware is accomplished. The flash memory of the device comprises, but be not limited to the mobile and the tablet computer. It is noted that the size of the System firmware programming to the flash memory should be adjusted to the size of intermediate file system before adjustment, so as to accommodate the data with a size of 500M. Such adjustment so easy, and as an embodiment, that executing the command “$resize2fs /dev/sdf ” when the mirror of the system generated by the file system “ext3” is located in partition “sdf*. If the file system has the format of “ntfs”, execute the command “ntfsresze -x /dev/sf ’ to restore the size of the programmed system hardware to the size of the intermediate file system. The method of the invention increases programming speed of the system firmware, reduces the time of programming of the system firmware effîciently. For example, if the size of the intermediate file system of the mirror of the system of the popular Andriod mobile with a size of 1.5G is adjusted to 800M to meet the requirement of the file system, the programming time is reduced from 118s to 66s.
In conclusion, the invention adjusts the size of an intermediate file system prior to generating a mirror of the system, generates the mirror of the system according to the size of the adjusted intermediate file system. Thus the time of making the mirror of the system and transmitting the mirror to the memory is saved efficiently, the time of programming the mirror of the system into the flash memory of device is saved, the time of programming the mirror into the hardware is reduced efficiently, and the programming speed of the system firmware is increased.
