The typical power-up sequence is the following:

# (optional) PMIC_LICELL is powered by a Lithium coin cell battery

#*iMX6UL SNVS domain is powered ([[Pinout_(AXEL_ULite)#VDD_SNVS_IN|VDD_SNVS_IN]])

# VIN_SOM main power supply rail is powered

#*iMX6UL SNVS domain is powered ([[Pinout_(AXEL_ULite)#VDD_SNVS_IN|VDD_SNVS_IN]])

# CPU_PORn (active-low) is driven low

# PMIC_PWRON signal is pulled-up (unless carrier board circuitry keeps this signal low for any reason)
