Embodiment Construction

[0027] In order to describe the technical content, structural features, achieved objects and effects of the technical solution in detail, the following detailed description is given in conjunction with the specific embodiments and the accompanying drawings.

[0028] see here figure 1 , our solution introduces a chip quick boot method, which can start at step S102. When it is detected that the flash memory in the chip needs to be started in four-wire boot mode, the firmware header file is read from the flash memory through single-wire mode, and then S103 is performed to detect the firmware. Whether there is configuration information about the boot mode in the header file, if so, S104 loads the configuration information of the four-wire boot mode, and uses the four-wire mode to start the chip quickly; here, the four-wire mode is used to start the chip. A sub-mode, a second sub-mode or a third sub-mode is tried. In practical applications, experiments have proved that several fla...

Abstract

A chip quick start method and storage medium, wherein the method comprises the steps of: when it is detected that the flash memory in the chip needs to be started in a four-wire boot mode, a firmware header file is read from the flash memory through a single-wire mode, and the firmware header file is detected. Regarding the configuration information of the startup mode, if it exists, load the configuration information of the four-wire startup mode, and use the four-wire mode to quickly start the chip; Try the sub-mode or the third sub-mode: Our technical solution designs three groups of default startup methods by looking for the characteristics of more than 100 flash memory on the market. Any flash memory on the market can use at least one of these methods. Startup of four-wire mode. Finally, the technical effect that the chip can start quickly no matter what kind of flash memory is matched is achieved.

Description

technical field [0001] The invention relates to the field of chip devices, in particular to a method for quickly starting a chip. Background technique [0002] With the upgrading of technology, SPI Norflash has developed from 1-wire data mode to support 2-wire and 4-wire data transmission mode, and the transmission speed has been greatly improved. In the early SPI Norflash 1-wire data mode, the transmission protocols of various SPI Norflash manufacturers are compatible. However, after the development to the 4-wire mode, each manufacturer of the 4-wire transmission mode protocol is incompatible, and even different particle models from the same manufacturer are not compatible. This brings great difficulty to the Soc chip's BootRom program to support 4-wire transmission mode to achieve fast startup. The BootRom program is an unchangeable piece of code that is solidified on the Soc chip and is the earliest executed when the Soc chip is powered on. Patent document 201611064399...
