如何实现MSP432的从bootloader到APP的跳转？
Boot程序的MAP安排如下：
*******************************************************************************
*** PLACEMENT SUMMARY***
"A1": place at 0x00000000 { ro section .intvec };
"P1": place in [from 0x00000000 to 0x00001fff] { ro };
"P2": place in [from 0x20000000 to 0x2000ffff] { rw, block CSTACK, block HEAP };
Section Kind Address Size Object
------- ---- ------- ---- ------
"A1": 0x144
.intvec const 0x00000000 0x144 msp432_startup_ewarm.o [1]
- 0x00000144 0x144
*******************************************************************************
APP程序的MAP安排如下：
*******************************************************************************
*** RUNTIME MODEL ATTRIBUTES***
CppFlavor = *
__SystemLibrary = DLib
*******************************************************************************
*** PLACEMENT SUMMARY***
"A1": place at 0x00002000 { ro section .intvec };
"P1": place in [from 0x00002000 to 0x0003ffff] { ro };
"P2": place in [from 0x20000000 to 0x2000ffff] { rw, block CSTACK, block HEAP };
Section Kind Address Size Object
------- ---- ------- ---- ------
"A1": 0x144
.intvec const 0x00002000 0x144 msp432_startup_ewarm.o [1]
- 0x00002144 0x144
*******************************************************************************
long App_add = 0x00002000 ; //应用程序
Boot中跳转到APP的子程序为：
void set_pc()
{
__set_MSP((*(volatile uint32_t*) App_add) ); //设置栈指针
(*(void(*)(void))(*(volatile uint32_t*) (App_add + 4)))(); //APP复位中断地址
}
可是当Boot程序运行到set_pc()时，就进入了Boot程序的IntDefaultHandler(void)中断
了。
在set_pc()中我还应该做些什么？
