与您交流：关于你的《基于at91rm9200重映射机制的修正》一文中，先判断是否已经重映射sram为0x0地址，之后再进行拷贝向量表，的疑问？？ 1.sram不论重映射前与后，都可以在0x20 0000地址可以访问到。所以，无论哪种情景，都可以将中断向量表直接拷贝到这个地址，无须作判断。 2. /*relocate exception table*/ /* 您要的是向量表的起始地址，可这是一个位置有关的代码,代码重定位之前应该不能正确访问,也就是说,掉电复位的情景应该无法实现*/ ldr r0, =_start /*应该将上面这条指令换成位置无关代码adr r0, _start*/ ldr r1, 0x0 /*将上面这个地址换成，0x20 0000 ldr r1,0x200000*/ mov r2, #16 copyex: >>>>>>>>>>>>>>>>>
