Problems solved by technology

During this process, if uboot fails to start, it will cause the Soc chip to fail to start, and thus cause the entire system where the Soc chip is located to fail to work normally
At present, there is no effective solution to this phenomenon

Embodiment approach

[0066] Based on the above embodiment, this embodiment further explains and optimizes the technical solution. As a preferred implementation mode, the above starting method also includes:

[0067] Count the target times of uboot startup failures, and judge whether the target times exceed the preset times;

[0068] If so, it is determined that the firmware of uboot is faulty.

[0069] It can be understood that in practical applications, due to the influence of various external factors, the uboot curing program may fail. In this case, if the uboot is always started according to the method provided by this application, then It will greatly waste CPU resource overhead.

[0070] Therefore, in this embodiment, in order to avoid the occurrence of the above situation, the target number of uboot startup failures is further counted during the uboot startup process. If the target number of uboot startup failures exceeds the preset number of times, it means that the uboot is solidified If...

Abstract

The invention discloses a uboot starting method and device, equipment and a medium, the uboot starting method and device are applied to a CPU in a Soc chip, the Soc chip is internally provided with afirst nor Flash and a second nor Flash which are redundant to each other, and the first nor Flash and the second nor Flash both store a curing program of uboot; the method comprises the steps: when the Soc chip is powered on, starting a state register, wherein the state register jumps once within a preset time; and according to the state of the state register, sequentially starting the curing program of the uboot in the first nor Flash or the second nor Flash until the uboot is successfully started. Obviously, according to the method, the uboot can be repeatedly started all the time by utilizing the mutually redundant nor Flash, so that the uboot in the Soc chip can be successfully started.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a uboot startup method, device, equipment and media. Background technique [0002] Since Soc (System on a chip) chips can effectively reduce the development cost of system products, Soc chips have been widely used in data centers, video surveillance and other fields, and uboot (Universal bootLoader) is used in Soc chips The boot loader of the embedded system, under this technical background, the startup of uboot just seems more and more important. [0003] If you follow the method of starting uboot in the prior art, you need to burn uboot in nor Flash in advance. When the Soc chip is successfully powered on, the CPU in the Soc chip will first start from the ROM (Read Only Memory, read-only memory). The zero address starts to execute the system firmware, and then jumps to nor Flash to execute uboot to start uboot. During this process, if uboot fails to start, it will cause the...
