Chip : STM32F429/439.

I tried to set BFB2 from ST-Link Utility. From the user manual, it should have a check item under Target/Option Bytes.

I downloaded both v3.0 and V3.1. both missing the BFB2 check box. Is there anything I did wrong?

Or is there other better way to set it?

It looks to be a bug/oversight. Perhaps you can change it programmatically.

I just found out that in stm32f4xx_flash.c of the StdPeriph Lib v1.1. There is no support of BFB2 set/reset. The function of dual bank support begin to exist on v1.2.0RC2 for F429/439 chip. My guess is that the ST-Link Util 3.1 on website is still using v1.1 and the new version that manual states about the check box of BFB2 is not released yet. V1.1 of the stdPeriph lib is limited or no support on new 429/439. Hope v1.2 can release soon.
