在调试T_Card时候时钟检测状态时没有stable，以至于读不到卡！
在升级时T_Card是正常的，开机后SDCLK 没有波形，也识别不到卡！
插卡后的打印信息如下：
[HSMMC0] Card is Inserted!
[HSMMC0] Turn OFF the F/B delay control.
SDHCSetRate - Clock Control Reg = 8001
SDHCSetRate - Actual clock rate = 187500
CSDHCSlotBase::WaitForReg: Timeout (1000 ms) waiting for (ReadReg<2>(0x2c) & 0x00000002) == 0x00000002
[HSMMC0] CSDHCSlotBase::SDClockOn: Timeout waiting for CLOCK_STABLE
[HSMMC0] Setting for 1 bit mode , Clock Rate = 100000 Hz
[HSMMC0] Turn OFF the F/B delay control.
SDHCSetRate - Clock Control Reg = 8001
SDHCSetRate - Actual clock rate = 187500
CSDHCSlotBase::WaitForReg: Timeout (1000 ms) waiting for (ReadReg<2>(0x2c) & 0x00000002) == 0x00000002
[HSMMC0] CSDHCSlotBase::SDClockOn: Timeout waiting for CLOCK_STABLE
请高手帮忙看看是什么原因？

估计还是时钟的问题
