2440启动流程 启动方式:nor flash启动、nand flash启动 地址布局: 选择nor flash启动时,SROM(nor flash)地址为0x00000000 选择nand flash启动时,SRAM(SteppingStone)地址为0x00000000 SDRAM(内存)地址为0x30000000 启动流程: 1.第一阶段 首先,处理器复制nand fl...
ARM机器码分析 2025年02月21日
  我们编写的汇编程序还是不够底层,CPU都是对机器码进行操作的,所以还需要用汇编器将汇编代码转换成机器码才能被CPU处理。下面举几个例子来说说分析ARM机器码的方法。   对编译连接之后得到的ELF进行反汇编:arm-linux-objdump   查看得到的反汇编代码。这里如果想同时看到汇编代码和机器码,在编译的时候需要加上-g调试选项。   1、mov r1,#0x...
ARM启动流程 2025年02月21日
  S3C2440支持两种启动方式:norflash启动和nandflash启动。   一、norflash启动   NOR Flash 的特点是芯片内执行(XIP ,eXecute In Place),这样应用程序可以直接在Flash闪存内运行,不必再把代码读到系统RAM中。ARM处理器上电之后会从零地址去取指令,所以代码一定要放在norflash的最前端,处理器才能继续往...
