I'm using an stm32f429 2MB dual bank mcu and erasing a sector in flash bank2 from code running in bank1. I can't achieve this without the code in bank1 stalling. I can't find any documentation relating to the stm32f429 2MB to allow this.

For the  stm32f429 1MB dual bank there is documentation relating to setting dual bank mode, and for the  stm32lxxx there is documentation relating to setting dual bank mode, but not for the stm32f429 2MB dual bank. I'm wondering now if read-while-wri...
