Latest version of AN4581

[mprt42]

Hi,

There is a AN4581 (i.MX Secure Boot on HABv4 Supported Devices) Rev. 4 from 2020:

https://de.scribd.com/document/811030804/AN4581

However If I search your website or the internet, I can only find outdated versions from 2012 or 2018.
Can you tell me where I can find the latest revision of AN4581?

Thanks

This AN for secure boot is confidential, you need to sign an NDA with NXP.

It's better to create an internal ticket from https://support.nxp.com/s/?language=en_US
