Question

SFI on STM32H533 terminates early

Hello,

 

I am re-posting this.

My original post on the old forums seems to have disappeared !?!

I have prepared an SFI (with firmware, debug authentication key and option bytes)

After SFI I want to boot to address 0x0C000000

To achieve this I have programmed Option Bytes:

BOOT_UBE = 0xB4 (OEM-iROT)

TZEN = 0xB4

PRODUCT_STATE = 0x72 (closed)

(and some other bytes)

 

After (successful ??) SFI, the Option Bytes are not programmed correctly

It seems that SFI terminated early. PRODUCT_STATE is 0x17, UBE = 0xC3

 

Programming log is attached

 

Am I being stupid? Am I missing something…?

 

Note : I cannot attach the programming log because the attach feature does not work anymore. But it’s not really a useful feature anyway right? Who needs it.

 

So I have made a copy-paste instead.
