Hello,
Unfortunately, it is not possible to use the same bootloader of the S12(X) devices for the newer family.
The 16-bits MCUs MagniV is available as the newest high voltage MCUs family. These MCUs runs directly from the 12V power supply – you don’t need an external power supply regulator.
The bootloader for this family is available below:
Simple Serial Bootloader for S12Z - AN draft
More information about the MagniV family can be found on the NXP site:
S12 MagniV® Mixed-Signal MCUs for Automotive and Industrial | NXP
I hope it helps.
Best Regards,
Diana
