Abstract

The invention discloses equipment based on a universal boot loader and a starting method of the equipment. The starting method of the equipment based on the common bootstrap loader comprises the following steps: when detecting pre-set operation for starting the universal boot loader (U-Boot), operating a first U-Boot file stored in a first storage region; reading a second U-Boot file stored in a second storage region, and judging whether the second U-Boot file is complete or not; when the second U-Boot file is complete, starting the equipment through the second U-Boot file; when the second U-Boot file is not complete, copying the first U-Boot file to the second storage region and replacing the second U-Boot file; starting the equipment through the replaced second U-Boot file. With the adoption of the manner, the problem that U-Boot upgrading fails, so that the equipment cannot be started can be avoided.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a device based on a general boot loader and a starting method thereof. Background technique [0002] The Universal Boot Loader (U-Boot) is currently the most widely used open source boot loader, which supports most mainstream 32-bit hardware platforms and mainstream operating systems. It has rich instructions and Peripheral drivers can meet the needs of most of these systems. Because U-Boot contains some hardware drivers, sometimes it is necessary to upgrade the U-Boot driver of the product, or it is found that there is a program error BUG in U-Boot later, and it needs to be upgraded to enhance the stability of the system. [0003] In the prior art, the U-Boot loading method is usually to upgrade the U-Boot backed up in a single Flash. However, when the U-Boot in the device is upgraded, if the U-Boot upgrade fails, the device cannot be started normally. Contents of the i...
