    Quark SE C1000 VCCOUT_QLR1_3P3 power down after QMSI 1.4.0 upload

      Hi.

       

      I am trying to develop board with Quark C1000.

      When i access first time to my board, i can find connected to serial message on System Studio, can update ROM and can launch firmware.

      But after i update ROM to QMSI 1.4.0 than VCCOUT_QLR1_3P3(K5) is down to 0V(It was 3.3V before update rom) and cannot update ROM and cannot launch firmware.

      VCCOUT_HOST_1P8(K6) and VCCOUT_QLR2_1P8(K4) also down to 0V.

      Could it be due to QMSI 1.4.0?

      If so, how can i fix it?

       

      VCCOUT_QLR1_3P3(M3) pin is connected with

      COMP_AREF(H9)

      VCC_IO_AON(H10)

      VCC_IO_AON1(F6)

      VCC_IO_AON2(G8)

      VCC_ADC_3P3(M10)

      VCC_CMP_3P3[2](M8)

      VCC_VSENSE_ESR1(L5)

      VCCOUT_ESR1_3P3(M5)

      in my board.

       

      And my development environment

      Windows 7

      System Studio 2016.2.094 for Microcontrollers Update 2

       

      Thanks,

      Jeong
