Arm u-boot linux内核的内存位置
目前，我有一个ARM设备，它使用U-boot加载android操作系统。我希望用linux取代android。因此，我所做的是将为ARM设备编译的linux副本加载到sd卡上，引导到U-boot引导加载程序中。现在的问题是我应该告诉U-boot什么内存位置来启动vmlinuz linux内核 我怎么才能知道呢？或者指出一些资源也很好 谢谢 以下是连接到串行端口的当前启动顺序Arm u-boot linux内核的内存位置,arm,embedded-linux,u-boot,Arm,Embedded Linux,U Boot,目前，我有一个ARM设备，它使用U-boot加载android操作系统。我希望用linux取代android。因此，我所做的是将为ARM设备编译的linux副本加载到sd卡上，引导到U-boot引导加载程序中。现在的问题是我应该告诉U-boot什么内存位置来启动vmlinuz linux内核 我怎么才能知道呢？或者指出一些资源也很好 谢谢 以下是连接到串行端口的当前启动顺序 Reg Version: v1.1.0 Reg Time: 2014-10-115:15:35 Reg Name

较旧的ARM Linux内核（即预设备树）是专门为每个SoC/板变体配置和构建的。
现代ARM Linux内核可以为一个或多个SOC构建，内核启动时使用设备树blob来描述正在使用的板 您还没有提供任何细节来说明您拥有的内核是否足以引导您的“ARM设备” 现在的问题是我应该告诉U-boot什么内存位置来启动vmlinuz linux内核 ARM Linux应该使用zImage文件启动，而不是vmlinuz文件 设备上物理RAM的起始地址是什么 按照惯例，ARM Linux内核将在物理RAM加上0x8000（32K）偏移量的基础上执行。有关更多详细信息，请参阅 zImage文件是自解压的，可以（通过SD卡的U-Boot）加载到内核加载/执行地址之上的任何合适内存地址（同时为DT blob留出空间，而不是clobber U-Boot） 或者指出一些资源也很好
请在构建内核的地址尝试Russel King's和Vincent Sanders.。还有一个解压器在其他地方运行，并解压到您运行内核的地址。解压器/初始二进制文件可能与位置无关。尝试时发生了什么？我实际上没有尝试过。但在尝试在另一台设备上运行OpenWrt之后，我认为你是对的。有一个特定的内存位置，引导加载程序试图引导内核。为了从内核获取更多信息，请尝试将参数
