Embodiment Construction

[0023] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0024] An embodiment of the present invention provides a processor initialization method, figure 1 is a flowchart of a processor initialization method according to an embodiment of the present invention, such as figure 1 As shown, the following steps S102 to S104 are included.

[0025] Step S102, configure processors under the same architecture during hardware reset, wherein the processors belong to the same series and have the same core.

[0026] Step S104, initialize the processor and its off-chip resources.

[0027] In the related art, one boot program can only guide one single board, which lacks flexibility and is inconvenient for version management. In the embodiment of the present inv...

Abstract

The invention discloses a processor initialization method and device. The method includes the steps that processors in the same framework are configured during the hardware resetting period, wherein the processors belong to a same series and are same in kernel; the processors and off-chip resources of the processors are initialized. According to the processor initialization method and device, the processors in the same framework are configured and initialized through a same bootstrap program, and bootstrap programs of like products are compiled into a same file, and therefore flexibility of the bootstrap programs is improved, the editions of the bootstrap programs are convenient to maintain and manage, different types of hardware equipment, namely the off-chip resources, are initialized, and hardware difference is further masked for underlying software.

Description

technical field [0001] The present invention relates to the communication field, in particular to a processor initialization method and device. Background technique [0002] In embedded devices, the operating system needs to be guided through a boot program. At present, a large part of communication products on the market use PowerPC architecture processors, and U-Boot is selected as the boot program. The realization concept of U-Boot is to use different board-level configuration files for different boards, which is a completely static way, that is, one boot program can only guide one board, the boot program lacks flexibility, and version management is inconvenient. Contents of the invention [0003] The invention provides a processor initialization method and device to at least solve the problems in the related art that one boot program can only guide one single board, lacks flexibility and is inconvenient for version management. [0004] According to one aspect of the p...
