SATA not working after resume in wince 7

[Sowmya1z]

Dear All,

   I  am testing power management in imx6q SDP platform. The target OS is Wince7. After resume, SATA is mounting as HardDisk. I am creating a folder say "Folder 1" in SATA, the folder is not displaying. Again i am creating a folder say "Folder 2", the contents present in the SATA is vanished, but the created folder is present in the SATA. After reboot the system "Folder 2" is not present in SATA but whatever contents already present in SATA is present. After debugging i found that in DevInit() function the print is coming as "device presence indication 0x1" , which means device is present but phy communication is not established. How to establish phy communication. Please help me to solve this issue.

Thanks & Regards,

Sowmya

Hi Sowmya,

Can you check the Sata driver PowerUp and PowerDown function and to do the HW re-connection in PowerUp function.
Or you can do the same thing in the IOCTL of PowerSet to D4 and D0 state.
