Debugging from bank 2

[Abdelrahman]

I'm working with Nucleo-f439zi board.

I use dual banking feature.

I cannot find a way to debug from bank 2

how to debug application from bank 2 ?

[Kamil Duljas]

So you run application from bank2 ? Can't use debug option in stm32cubeide?​

[Abdelrahman]

yes, I can flash my code into bank 2 using stm32 st-link utility tool

but cannot debug it

The debugger can see the memory as the MCU sees it.

Add some code to map the banks appropriately, and step into and across the control transfer.

Perhaps build a loader in such a way that it is duplicated in the front of both banks, and then "forks" into the application in the bank of interest.
