Issue about KW45 dual image boot enable

FVT23029 — Mon, 07 Oct 2024 07:22:46 GMT

I refer to "15.2.3.1 Dual image boot" in KW45RM.pdf and using Secure Provisioning Tool v8.0 to set ROMCFG/IFR0 as following:

and I prepared two binaries from the "kw45b41zevk_hello_world", one will show "Hello World 1" and another one is "Hello World 2"

I flashed the "Hello World 1" into address 0x0 and then flashed "Hello World 2" into address 0x80000 but I always got "Hello World 1" message after boot up.

Does any steps miss with my method?

Hello,

Hope you are doing well. I would recommend checking this Application Note: "AN14109: KW45 and K32W148 Secure Boot Using the SEC Tool".

This file is under Secure Files. If you have an active NDA, you could request it directly on NXP.com.

Secure Access Rights | NXP Semiconductors

Could you please follow the process?

Also, I would recommend checking the Secure Access Rights FAQs | NXP Semiconductors
