2410Init.s包括了板子上电后的初始话,具体有几个步骤:
讲述S3C2410启动程序设计
1. 屏蔽所有中断,关看门狗。
2. 根据工作频率设置PLL寄存器
3. 初始化存储控制相关寄存器
4. 初始化各模式下的栈指针
5. 设置缺省中断处理函数
6. 将数据段拷贝到RAM中,将零初始化数据段清零
7. 跳转到C语言Main入口函数中-2410Init.s including the board after the initial power-on, then there are several specific steps: start the program design one described S3C2410. Mask all interrupts, Guan watchdog. 2. According to the operating frequency is set PLL register 3. Initialized memory control-related registers 4. Initializes the mode stack pointer 5. To set the default interrupt handler 6. Will be copied to the RAM in the data segment will be zero initial data segment Clear 7. jump to C-Main entry function
