#define pISR                (*(unsigned *)(0x30000000+0x18)) // Virtual Address 0x0 is mapped to 0x30000000, ISR Address is VA 0x18 我的内存起始物理地址是0x30000000的 // make value to assemble code "b IsrHandler" pISR =(unsigned)(0xEA000000)+(((unsigned)IsrHandler - (0x80000000 + 0x18 + 0x8) )>>2); 和ADS的写法有点不一样哦。
