Debugging from bank 2

I'm working with Nucleo-f439zi board.I use dual banking feature.I cannot find a way to debug from bank 2how to debug application from bank 2 ?

I am working with an STM32F429 in a project and I am seeing random BusFaults, captured against erroneous execution of ldr r4, [r2, #12]. This is one example.

I am working with an STM32F429 in a project and I am seeing random BusFaults in random code locations, very infrequently but obviously problematic. I traced one earlier to this instruction ldr r4, [r2, #12].You'll see from the screen capture attached...
