Hello,I wrote a Boot program in flash to initialize sdram and copy the app program to run in sdram. The current state is able to jump and run normally, but the length of jump time seems to be positively correlated with the size of global variables in...

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...
