Hi,

Regarding to USB regulator output voltage, it is set 3.2V by OUTPUT_TRG in  PMU_REG_3P0 register.

I think USB normally use 3.3V.  Also, uboot use default value of 3.0V.

Are there any reason to set the voltage as 3.2V in Linux?

Best Regards,

Sugiyama

There is no special reason to set 3.2V output. All voltages in range of 3.0V to 3.3V are valid for USB operation.


Have a great day,
Artur
