Since the last update I get the following errors on some Devices:

The errors do not occur with every boot.
Sometimes the error is issued only a few times, sometimes it comes every few seconds.

Can anybody help me with that?

Are you using TrustFence and encrypted partitions or locked hardware? => contact Digi Technical Support.

Maybe this NXP help applies:
