I.MX8QX PLUS PMIC issue

[suhas_mv]

Hi,

We are using PMIC PF8100 (P/N: MC33PF8100FJES) for i.MX8QXP Processor,but in the OTP report,SW3 and SW4 are Disabled. But these powers GPU and CPU.

Can you please help me understanding why these are disabled.

Note: Almost All PF8100 Pre-programmed OTP, SW3 and SW4 are disabled.

The PMIC used in the Evaluation Board  is PC33PF8100CCES, for this i didn't found any datasheets.

Cheers,

Suhas

Hi Suhas

they are disabled for power-up sequence and can be enabled by software

after processor powered up. Note in i.MX8QXP/QM SCU (M4) module is

used for initial starting up of processor.
