Bootloader中xs128的中断向量如何重映射

22-2016421 · 发表于 2016-9-5 15:53:46

最近在做XS128的Bootloader，遇到了一个问题，就是中断向量该如何重新映射？看手册需要配置IVBR寄存器，但不知该怎么用？特来求助大神，不知有谁做过这方面的没有。现在已经可以将s19文件烧到flash中，只要没有中断向量的程序都能正常运行，但有中断向量的不知该如何重新映射。

我知道答案目前已有7人回答

配置IVBR寄存器就好了，重新搞个中断向量表

配置IVBR寄存器就好了，重新搞个中断向量表

void main(void)
{
IVBR=0xEF;//在这里配置了IVBR
DisableInterrupts;
INIT_PLL();
initialize_ect();
INIT_port();
LEDCPU_dir=1;
LEDCPU=0;
EnableInterrupts;

复制代码

下面是配置的向量表，还请版主看下哪里有问题

#pragma CODE_SEG NON_BANKED
// 声明外部中断函数
//extern void Timer0_C0(void);
extern void _Startup(void); //Startup routine */
#pragma CODE_SEG NON_BANKED
/* Interrupt section for this module. Placement will be in NON_BANKED area. */
__interrupt void UnimplementedISR(void) //定义在NON_BANKED区
{
asm BGND; //空的中断函数
}
typedef void (*near tIsrFunc)(void); //定义了函数指针类型
//定义一个函数指针数组中断表，从0xEF00地址开始装载各个中断函数的首地址

楼主，这个不是中断程序都能运行？只需要改linkfile文件就能做到吗？

请问楼主问题解决了吗？我现在也遇到了IVBR寄存器的配置问题，我用的芯片是MC9S12XET256
