Hi Expert,
How to control PMIC-B LDO1 output from 3.3V(bypass mode) to 1.8V(LDO mode)?
We know that the voltage switch is for switch SD voltage work status from initialization to normal work status.
According to below diagram, it seems that there is a MMC1 IO which can control TPS659411 SD voltage through GPIO2, but from schematic, GPIO2 is only a test point, How to control PMIC-B LDO1 output from 3.3V(bypass mode) to 1.8V(LDO mode) in J721E EVM?
