2.3 Power tree
There is a USB Type-C power supply that needs to be connected to the i.MX 8M Plus LPDDR4 EVK board at connector J5 (Type-C
Port0). The other powers on the EVK board are generated from PMIC and discrete devices to supply the whole system.
Figure
6 shows the Power Tree.
Figure 6. Power tree diagram
In Figure 6 , the developers can see all the voltage supplies used on the EVK board. When some modules are not enabled, the
related power supplies might be shut down by software. Table 3 lists the power rails on the board.
