The chip peripheral power hardware design as bellow:
The VDD_ARM_SOC_IN is 1.1 V input, provided by the PMIC SW1. 3V3_VDD_HIGH voltage of 3.3
V, which is provided by the PMIC and can provide 350ma current
◆Starting Circuit
i.MX 6UltraLite processor supports a variety of startup mode, after the power on reset, ROM
code boot will work based on the internal register BOOT_MODE[1:0] , Boot_MODE[1:0] defined as
follows:
SBC-EC9100 use 2 bits for encoding the switch
SW3 as boot mode choice, the switch to off position,
using the chip internal pull-down, logic is set to 0, the
switch to on, use external 10K, logic is set to 1, as
shown in the figure on the right：.
