Why STM32G484QETx is getting locked ?

[Tshad.1]

STM32G484QETx is getting locked because of wrong configuration in secure boot and secure firmware update. Kindly suggest me the right configuration along with code and examples. I am attaching a pdf for your reference.

Hello @Tshad.1​,

could you please be more precise regarding your issue.

What do you mean by locked ?

SBSFU is provided with configuration that enables security protections.

So if you mean by locked that you cannot debug the application, this is normal.

You should still be able to attach under reset with the CubeProgrammer and launch a regression (Set RDP to 0xAA : level 0), disabling the PCROP areas at the same time.

Best regards
