STM32G474 Configuring SEC_SIZE1 for enabling secure memory

SHuddar
Visitor

Hello,

I am trying to configure the secure memory in Secure Protection Bank 1 of options bytes section and for this I have followed the STM32 MOOC tutorial to understand the concept of using secure boot code. But I am facing issues as the base address for Bank 1 is expected be 0x08000000 as mentioned in STM32 G4 system memory protection document and also in tutorial whereas its showing as 0x00000000 

Below is the screenshot from STMCube Programmer Option Byte settings from G474RE Board for your reference.

I have also checked the similar settings with G071 board and I am able to get the base address as 0x08000000 as below and implement the secure boot code but unable to do in G474.

Are there any other settings that I am missing out to configure in G474 to add the SEC_SIZE1 value?

Can you please help me with this?

Thanks
