I'm trying to use advanced secure boot feature of HSE-B of my S32k314 controller in our project.

after enabling secure boot unable to find any way to update IVT to change BOOT_SEQ from 0 to 1.

because secure boot only impact after BOOT sequence bit is 1.

SBAF will directly release core if BOOT_SEQ bit is 0. if secure boot feature to work HSE should get control.

Hello @Suheel890,

Please use support tickets instead of the public community for HSE related questions, the HSE FW documentation, demos etc. are all under an NDA.

The BCW can be changed here though:
