How to implement IAP(Ymodem Protocol) on DualCore(h745)?

I'm tring implement IAP on NUCLEO-H745ZI-Q.

So. I seen STM32h743-eval IAP Example.

But I have two bank and two core for cm7 and cm4.

I don't know how to implement the bootloader.

And should I create and transfer bin files for cm4 and cm7 respectively?

You can merge the hex files (see this thread) and do the operation once as stated previously, the two cores are seeing the same memory.

Up to you..

Both cores see the same memory.

You could use two binaries or put some kind of object or meta data, to describe multiple sections with lengths and addresses.

You could also stage the update in a QSPI

When i implement IAP, then make bin then Make each bin files for CM4, CM7.

Download twice for cm4 and cm7 or merge bin and once download?

You'll need to make that choice. If you do a single download you must impart how the content is split up.
