[STM32H750] How to Debug in SDram

[Passerby]

I use STM32H750XBH6, Flash is 128kBytes.

My Program is too big,so I Write a BootLoader to load the program into sdram ,and run it in sdram.

This is the setting of my APP in keil，

This way can run the program successfully , but I cannot debug APP in Keil.

How Can I Debug APP in Keil?

Thanks!
