官方的例程
/* Test if user code is programmed starting from address "ApplicationAddress" */
if (((*(vu32*)ApplicationAddress) & 0x2FFE0000 ) == 0x20000000)
{ /* Jump to user application */
JumpAddress = *(vu32*) (ApplicationAddress + 4);
Jump_To_Application = (pFunction) JumpAddress;
/* Initialize user application's Stack Pointer */
__MSR_MSP(*(vu32*) ApplicationAddress);
Jump_To_Application();
}
这个代码是错误的，容易导致堆栈溢出死掉。跳到应用区，堆栈指针就不对了。
现在用汇编实现。 |
