  • How to I implement the different DDR memory application?
    • The output voltage for BUCK8 can be adjusted by U-Boot in the initial startup depending on the memory type in use. The voltage change handled by U-Boot is acceptable for PMIC because the validity in the power sequence is confirmed by NXP and no other sideband effects are found during their validation.
  • How do I disable buck6 in hardware terms?
    • BUCK6 is initially ON as the default setting and its output voltage is monitored during the power sequence as an one of the triggers to de-assert POR_B, the power good signal to SoC. So it is not recommended to turn off BUCK6.
