    About no response for the SLP_A# of PCH(C612,Wellstrubg,Grantley)

    EVERSEC Community Member

      Dear,

           In our Board(New Design),there isn't Deep Sx. So we provide the same one 3.3V to VccDsw and VccSus, and tied RSMRST# and DPWROK together. This design reference the Datasheet of PCH and PDG for Grantley and CRB(MaYan City). By the Debugging, we can get that the quality of VccDsw and VccSus is very good, the ripple is less than 30mV. And we can get the SUSCLK after Set the RSMRST# and DPWROK. The fequency of SUSCLK is 32.768KHz,that is very accurate, and the quality of the wave is very good.

           But the SLP_A#  always keep low,Even we trigger the PWRBTN#. We can't find error in the Schematic and PCB. However,we found the voltages of DCPRTC and DCPSST are different from the description of Datasheet of C612.

           So we have no idea. Please help to analyze this problem. Thanks very much~!

          Hello, EVERSEC:

           

          Thank you for contacting Intel Embedded Community.

           

          In order to be on the same page, could you please let us know how many units have been manufactured, how many are failing, and the failure rate?

           

          Could you please give us pictures of the top side markings of the affected processors and chipsets?

           

          Could you please let us know if the schematics and layout have been verified by Intel?

           

          Waiting for the information that should answer these questions.

           

          Best regards,

          Carlos_A

                 Thanks your feedback. And please see the answer as the blue words as blew.

             

            In order to be on the same page, could you please let us know how many units have been manufactured, how many are failing, and the failure rate?

                   ----There are 6 sets have been manufactured. And all of them have the same prolbem.

            Could you please give us pictures of the top side markings of the affected processors and chipsets?

                    ---- The picture of chipsets as show as below.

            Could you please let us know if the schematics and layout have been verified by Intel?

                   ----Have not been verified by Intel. But the design refenence the CRB.

            Waiting for the information that should answer these questions.
