Hello NXP,

 

I made a board consisting of i.mx6 solox + pf3000.
CPU: MCIMX6X2AVN08AB
PMIC: MC34PF3000A3EP

After power on, VDD_ARM_CAP, VDD_SOC_CAP voltage do not rise.
After turning on the power,
CPU Side
  - VDD_ARM_CAP: 0.06V
  - VDD_SOC_CAP: 0.139V
  - PCIE_VP_CAP: 0.07V
  - VDD_HIGH_CAP: 2.5V
  - VDD_SNVS_CAP: 2.5 V
  - NVCC_PLL: 1.12V

PMIC Side
  - SW1A: 1.376V
  - SW1B: 1.370V
  - SW2: 3.31V
  - SW3: 1.347V

The PMIC voltage output is normal.
However, the CPU's VDD_ARM_CAP and VDD_SOC_CAP are not output.
I do not know why the output voltage does not rise.

Thank you for your help.
Kim Ki Soo.
