Problems solved by technology

Taking the system program system as an example, in order to meet the needs of users to add new data information during use, the size of the system image generated by the system program system is usually much larger than the size of the system program system. For example, a 500M system program may need to produce 1G or even more Large system image system.img, which leads to a very large system firmware, which makes it time-consuming to make the image and burns the finished image to the hardware at a very slow speed
[0004] In the prior art, in order to increase the programming speed of the system firmware, some manufacturers compress the system intermediate files with the system files in the storable data space first, then generate a system image based on the compressed intermediate file system, and then transfer it to the memory. This method speeds up the transfer to the memory to a great extent, but before finally burning the system image to the flash memory of the device, it is necessary to decompress the generated system image, and then burn the decompressed system image to the flash memory. This process is also time consuming

Embodiment Construction

[0024] The invention and its characteristics, configurations and advantages will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings. Like numbers designate like parts throughout the drawings. The drawings may not be drawn to scale, emphasis instead being placed upon illustrating the gist of the invention.

[0025] Aiming at the problem that the programming speed of the system firmware is low and the programming time is long, the present invention discloses a method for increasing the programming speed of the system firmware. By adjusting the size of the intermediate file system, a system image is generated according to the adjusted size of the intermediate file system, and then the The system image is transferred to the memory and written to the flash memory of the device. This method effectively reduces the size of the system image, saves the time for making the system image, the time for transfer...

Abstract

The invention belongs to the field of semiconductors, and particularly relates to a method for increasing the programming speed of system firmware. By adjusting the size of the intermediate file system, a corresponding system image is generated according to the adjusted size of the intermediate file system, and then the system image is programmed to the device. of flash memory. It effectively reduces the size of the system image, saves the time of making the system image, the time of transferring the system image to the memory, and the time of programming the system image to the flash memory, and effectively improves the programming speed of the system firmware.

Description

technical field [0001] The invention belongs to the field of semiconductors, and in particular relates to a method for increasing the programming speed of system firmware. Background technique [0002] System firmware (ROM) refers to solidified software, which writes a certain system program into the flash memory in a specific hardware system. The firmware of the mobile phone is equivalent to the system of the mobile phone, and refreshing the firmware is equivalent to flashing the system. [0003] The system program first generates a system image, and then transfers the system image to the device's memory and burns it to the device's flash memory. Taking the system program system as an example, in order to meet the needs of users to add new data information during use, the size of the system image generated by the system program system is usually much larger than the size of the system program system. For example, a 500M system program may need to produce 1G or even more A...
