请教STM32 的上电过程?

china_ldz 提问时间：2008-12-26 14:15 /

各位高人,想请教一下,STM32的上电过程,芯片上电后,是怎么运行的,跳到哪里,从哪里取第一条指令执行,有没有相关文档可供参考.感谢!

另在STM32 的库文件中有个 Stm32f10x_vector.c 的文件其中中断表如下:

const intvec_elem __vector_table[] =
{
{ .__ptr = __sfe( "CSTACK" ) },
__program_start,
NMIException,
HardFaultException,
MemManageException,
BusFaultException,

};

问题:
{ .__ptr = __sfe( "CSTACK" ) } 和 __program_start, 各有什么作用,在哪里用到?

再次感谢各位!
