S32K3 Debug Authentication

[Mateusz_K]

Where I can get more information about dynamic debugger authentication method (challenger & response), more than there is written in the Reference Manual, anyway? I want to know how response from the debugger should be generated? Are there any documents considering this matter?

Hi @Mateusz_K 

In addition to the information provided in the S32K3 Reference Manual and HSE_B Reference Manual on debug protection, PEMicro has posted the instructions on their website for S32K3xx Secure Debug with MULTILINK.

Using PEmicro Tools to Enable S32K3xx Secure Debug Support

Also, the HSE Demo App is provided with some of the scripts for Lauterbach TRACE32 used for debug authorization. As well as the application to enable the application debugging authorization feature.
