Hello,

It is highly recommended to follow the power-down sequence, specified ini.MX datasheet(s) :

The system design must comply with power-up sequence, power-down sequence, and steady state
guidelines as described in this section to guarantee the reliable operation of the device. Any deviation
from these sequences may result in the following situations:
• Excessive current during power-up phase
• Prevention of the device from booting

• Irreversible damage to the processor (worst-case scenario)

Have a great day,
Yuri
