步骤101：引导系统内核启动前，根据运行环境修正传递参数信息；Step 101: Before booting the system kernel, correct the parameter information according to the operating environment;
其中，所述传递参数信息为向所述系统内核包中的系统内核提供运行所需的参数信息。 The delivery parameter information is to provide parameter information required for operation to a system kernel in the system kernel package.
系统启动后，由引导程序引导系统内核启动；引导程序遍历存储器，查找所有可用的系统内核，并确定需要启动的系统内核；这里，可以根据传递参数信息中的系统内核版本号来确定需要启动的系统内核；确定需要启动的系统内核后，引导程序可以在存储器中读取需要启动的系统内核所属的系统内核包中的参数区，确定参数区的传递参数信息，获取系统内核启动所需的参数信息；引导程序可以根据当前的运行环境等信息，修改所述传递参数信息；如可以根据当前系统的双倍速率同步动态随机存储器(Double Data Rate Synchronous Dynamic-Random Access Memory DDR SD-RAM，)等随机存储器的页面大小、起始地址和大小等参数信息，修正所述传递参数信息中处于初始状态的随机存储器参数信息；After the system is booted, the bootloader boots the system kernel; the bootloader traverses the memory, finds all available system kernels, and determines the system kernel that needs to be booted; here, you can determine which ones need to be started based on the system kernel version number in the passed parameter information.

Parameter information such as a page size, a start address, and a size of the random access memory, and correcting the random access memory parameter information in the initial state in the transfer parameter information;
完成传递参数信息修改后，引导程序将需要启动的系统内核搬运到DDR SD-RAM等内存中，并引导所述系统内核启动；After the modification of the delivery parameter information is completed, the boot program transfers the system kernel that needs to be booted into the memory such as DDR SD-RAM, and boots the system kernel to boot;
系统内核启动后，读取与自身对应系统内核包中的参数区的传递参数信息，从而获取引导程序传递的参数。After the system kernel is started, the transfer parameter information of the parameter area in the system kernel package corresponding to itself is read, thereby obtaining the parameters passed by the boot program.
需要补充说明的是，在本发明实施例参数传递方法实现之前，需要预先在系统内核包中设置参数区，并在所述参数区中预设传递参数信息。It should be noted that, before the parameter transfer method of the embodiment of the present invention is implemented, the parameter area needs to be set in the system kernel package in advance, and the parameter information is preset in the parameter area.
通常在编译生成标准系统内核后，结合幻数，将两者的结合文件烧录到闪存(Flash Memory，Flash)等系统的非易失性存储器中，在系统启动时由引导程序引导所述系统内核启动；这里，将幻数和系统内核两者的结合文件为系统内核包；存储器中可以存储一个以上的系统内核包；其中，所述幻数由一组特定的数组成，引导程序可以通过幻数区分不同的系统内核包，在Flash中查找到有效的系统内核包；Usually, after compiling and generating the standard system kernel, combined with the magic number, the combined files of the two are burned into the non-volatile memory of the system such as flash memory (Flash), and the system is booted by the boot program at system startup.

如图2所示，可以在所述系统内核包中设置参数区；可以将所述参数区设置在所述幻数和系统内核之间，所述参数区成为所述系统内核包的文件头；在所述参数区可以预先根据系统内核启动或运行时需要参数设置传 递参数信息；所述传递参数信息可以设置成初始化状态；As shown in FIG. 2, a parameter area may be set in the system kernel package; the parameter area may be set between the magic number and a system kernel, and the parameter area becomes a file header of the system kernel package; In the parameter area, it may be pre-set according to the system kernel to start or run. Transfer parameter information; the transfer parameter information may be set to an initialization state;
进一步的，所述传递参数信息包括：所述系统内核启动过程中的运行环境参数信息、和/或提供所述系统内核运行过程中所需的运行参数信息；这里，所述运行环境参数信息包括：内存页面大小、内存的起始地址和大小等；所述运行参数信息包括针对不同系统内核在运行过程中所需的参数信息，如存储器分区占用情况等；所述传递参数信息还可以包括：系统内核的编译时间、和/或版本号、和/或版本类型等一些定制化的参数信息。Further, the delivery parameter information includes: operating environment parameter information in the system kernel startup process, and/or providing operation parameter information required during operation of the system kernel; where the operating environment parameter information includes The memory page size, the starting address and the size of the memory, and the like; the running parameter information includes parameter information required for the running of the different system kernels, such as the memory partition occupancy, and the like; the delivery parameter information may further include: Some customized parameter information such as the compilation time of the system kernel, and/or version number, and/or version type.

The system kernel runs information and performs corresponding processing; thus, completing information transfer of the system kernel to the boot program;
如在系统内核运行过程中，系统出现重启；通常引导程序无法获知重启原因，因此也无法做出处理。这里，系统内核在重启前可以在参数区设置重启标志位，通过重启标志位告知引导程序重启的原因，如用户指示重 启、系统内核升级完成重启、系统崩溃重启等；并且可以将重启时的日志存储到参数区，引导程序可以通过重启日志确定问题，并作相应处理，如重新分配内存等。If the system kernel is running, the system restarts; usually the boot program cannot know the reason for the restart, so it cannot be processed. Here, the system kernel can set the restart flag bit in the parameter area before restarting, and inform the boot program of the reason for restarting by the restart flag bit, such as user indication Start, system kernel upgrade complete restart, system crash restart, etc.; and the log at the restart can be stored in the parameter area, the boot program can determine the problem by restarting the log, and deal with it, such as reallocating memory.
