Question asked by DWYANE WADE on Feb 19, 2017

I'm developing the driver of SATA controller driver,but i get some problems。

After I send a "identify device" command, values of the relevant registers are as follows:

CQR(Command queue register) = 0x0

CAR(Command active register) = 0x0

CCR(Command completed register) = 0x1

CER(Command error register ) = 0x1

SSTATUS( SATA interface status register) = 0xa0001023

SERROR(SATA interface error register) = 0x00000800

Who can help me to solve the register error?
