Zynq7020实现PS端的软件复位
(参考 UG585手册的第26章节)
代码:
#define PSS_RST_CTRL_REG 0xF8000200 //PSS_RST_CTRL寄存器,绝对地址,
#define SLCR_UNLOCK_ADDR 0xF8000008 //SLCR_UNLOCK寄存器,绝对地址,
#define UNLOCK_KEY 0xDF0D //使能码
//Write the unlock key, 0xDF0D, to enable writes to
//the slcr registers. All slcr registers, 0xF800_0000
//to 0xF800_0B74, are writeable until locked using
//the SLCR_LOCK register. A read of this register
//returns zero.
#define PSS_RST_MASK 0x01 //复位码
void PsSoftwareReset(void)
{
Xil_Out32(SLCR_UNLOCK_ADDR, UNLOCK_KEY); //写使能
Xil_Out32(PSS_RST_CTRL_REG, PSS_RST_MASK); //复位
}
