DBANK Option Byte default STM32G4

[tomm5771]

What is the default value of the DBANK bit in STM32G4 MCUs. According to the reference manual, flash memory address 0x1FFF 7800 has that option bit, and the ST production value is 0xFFEF F8AA, which would make DBANK default to 1. Does this mean STM32G4 MCUs have DBANK flash enabled by default, and do I need to do anything further to set it to DBANK? Or will it always be enabled out of the factory?

Dear tomm5771,

  Yes - Dual bank is enabled as default option for factory produced devices. There is no need to perform programming to have dual bank option on factory produced devices.
