Hi, 

For the following devices:

STM32F469AE

STM32F469IE

STM32F469BE

STM32F469NE

Is the flash memory configured as single bank of 512KBytes? The RM0386 Reference manual does not not make it clear how the 512KByte flash is organized.

For the following devices:

STM32F469AG

STM32F469BG

STM32F469IG

STM32F469NG

STM32F479AG

STM32F479BG

STM32F479IG

STM32F479NG

Is the flash memory configurable to have dual bank?  The RM0386 Reference manual does not not make it clear if only some STM32F4x9xG devices are dual bank configurable or all STM32F4x9xG devices are dual bank configurable. 

Not all STM32F4xxxG devices are dual bank configurable.  For instance, the STM32F417IG in only a single bank device, whereas the STM32F437IG is a dual bank configurable device. Both devices have 1MByte of flash.

Hi see.juan,

As mentioned in (3.3.1 Flash memory organization) part of the RM0386, the flash memory of all the 1Mb devices

STM32F4x9xG

can be organized on dual bank by setting the DB1M option bit. Even DB1M is described as ''Dual bank 1Mbyte flash memory devices''. So, all 512 Kbytes devices

STM32F4x9xE

, are with a single bank flash memory. -Hannibal-
