Hello,
in the datasheet of the i.MX 7ULP (industrial variant) is written in a footnote:
"CA7 domain HSRUN is limited to 8760 power-on hours over the lifetime of the product. The total power-on hours includes all CA7 power modes except VLLS mode and VBAT mode in which the CA7 domain is internally power-gated."
Thanks and best regards,
Nico H.

Hello,
1> After a cumulative 2190 8760 hours of HSRUN, the DDR clock tree starts shifting and may require adjustment of the DDR duty cycle.
2> No
3> CA7 only
4> It is as stated "all CA7 power modes except VLLS mode and VBAT mode in which the CA7 domain is internally power-gated."
Best regards,
Aldo.
