i.MX 6ULL Impact of power down sequence

[ban45]

Hi

I heard that if you do not follow the power down sea sequence, it will affect the life.
How short is the lifespan if you don't follow the sequence? Also, how many times do you need to limit the number of times a 10-year operation fails to comply with a sequence?

best regard

Hi,

As per Hardware design guide Table 10, 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)

There might affect life as well but it completely depends on the use-case. And there are no official data for the same.
