IVT with HSE FW on S32K344

Dear NXP community,

I would like to know if IVT is mandatory for making use of HSE FW.

From my understanding, the main purpose of IVT is to specify the base address of HSE FW pink when flashing it.

NXP provides only the IVT that is demo-application specific so we cannot use it in another application.

If the IVT is mandatory, how can we generate another one for our application ?

My second question is, if I flash the NXP demo-application with IVT, can I erase it with my own application  later ?

Thank you in advance for your support.

Hi @IAussman 

HSE FW can be installed either using IVT or without IVT.

We provide document AN744810 “HSE FW install for S32K3xx” which describes how to install the firmware. It can be found in Documentation in Secure Files section:

 This corresponds to description from Readme file from HSE DEMOAPP package:

Even if you use IVT method, you can erase it after installation / replace it with own application with own IVT.

Regards,

Lukas
