Only SW1101[1-4] are used for boot selection. The left pins of SW1101 and SW1102 are useless for i.MX 8M Nano
UL, and either 0 or 1 is acceptable.
NOTE
2.3 Power tree
There is a Type-C power supply that needs to be connected to the i.MX 8M Nano UL DDR3L EVK board at connector J302. The
other powers on the EVK board are generated from NXP PMIC and discrete devices to supply the whole system.
Figure 4 shows
the Power Tree.
Figure 4. Power Tree Diagram
In Figure 4 , the developer can get all the voltage supply rails used on the EVK . When some modules are not enabled, the power
supplies might be shut down by software. Table 3 lists the power rails on the board.
