当程序运行到
void SDIO_DeInit(void)
{
SDIO->POWER = 0x00000000;
SDIO->CLKCR = 0x00000000;
SDIO->ARG = 0x00000000;
SDIO->CMD = 0x00000000;
SDIO->DTIMER = 0x00000000;
SDIO->DLEN = 0x00000000;
SDIO->DCTRL = 0x00000000;
SDIO->ICR = 0x00C007FF;
SDIO->MASK = 0x00000000;
}
这个函数时，执行SDIO->CLKCR = 0x00000000;程序会跳转到
void HardFaultException(void)
{
/* Go to infinite loop when Hard Fault exception occurs */
while (1)
{}
}
这个中断里，然后就出不来了，不知道怎么回事 |
