Problems solved by technology

With the development of the architecture, the booting process of the system becomes more and more complicated, and more and more firmwares need to be loaded during the booting process. In the existing firmware booting method, the parsing and loading of the firmware are implemented by different programs, resulting in system Takes too long to start up, degrading user experience

Abstract

The present invention provides a boot program-based firmware boot method, medium and equipment, the boot program-based firmware boot method includes: using the boot program to obtain firmware and parse it, read the first segment of sub-firmware and load it into the first storage area ; The startup program enters the entry address of the first section of sub-firmware, so that the first section of sub-firmware begins to run; the first section of sub-firmware runs and generates an entry parameter of a second section of sub-firmware, and returns to the Startup program; the startup program reads and loads the second sub-firmware to the second storage area, and then enters the entry address of the second sub-firmware; the startup program obtains the entry parameters of the second sub-firmware and Pass it to the second sub-firmware, so that the second sub-firmware starts running. The startup program-based firmware boot method can shorten system startup time and reduce system complexity.

Description

technical field [0001] The present invention belongs to the technical field of communications, and relates to a firmware booting method, in particular to a booting program-based firmware booting method, medium and device. Background technique [0002] The program in the BootRom area is a boot program solidified in the SoC (System on Chip, system on chip), which cannot be modified after the SoC leaves the factory, and is mainly used to execute the boot logic after the system is powered on. After the system is powered on, it is often necessary to load multiple segments of firmware. In the existing firmware boot method, the programs in the BootRom area only participate in the parsing and loading of the first segment of firmware, and the parsing and loading of the remaining firmware is completed by the previous segment of firmware. With the development of the architecture, the startup process of the system becomes more and more complicated, and more and more firmware needs to be...
