Hello,

on MCXN there's IPED/PRINCE which are on-the-fly encrypted/decrypted by the ROM. See also https://docs.mcuxpresso.nxp.com/secure/latest/06_processor_specific_workflow.html#booting-prince-enc...

And how does the ROM knows - you must specify what memory areas will be encrypted (on Build tab, see PRINCE or IPED buttons.

Hi, my question is :

How does the MCUXpresso Secure Provisioning Tool encrypt a BIN file and then boot it?
Firmware can be stored in flash in encrypted and signed form. How can the chip (MCXN947) automatically recognize the encrypted and signed firmware and boot normally?

thanks!

Hello,

First, if you post in English, there's higher chance you get an answer to your question.

Second, regarding the encryption - could you specify what device (MCU) you are using and what is the target boot memory?

There are different encryption methods for different MCUs/boot memories.
