FMC_SDRAM example isn't Loading to STM32H750B-DK

[Caan]

The STM32H750B-dk Based Custom Board isn't entering debugging mode when using STM32CubeIDE . But QSPI Example Code is working perfectly.

[TDK]

If the FMC settings are bad, the debugger won't be able to connect.

Does the program work in non-debug mode?

Consider putting in HAL_Delay(1000) prior to any FMC initialization, setting a breakpoint there, and stepping through.

When Downloading the binary directly into the Board same error Shows up.

The Custom Board is an Exact Replica of the STM32H750B-DK with Dual Flash (same part number and SDRAM IS42s322400F Connected with the same Pins as per the EVK). However, I am unable to start the basic TouchGFX code. The board is connected using STM32CUBEProgrammer with the external loader selected, and the erase and load functions are working properly.

Try to load the example to a STM32H750B-DK board and check again.

A sample Touchgfx Code I just now built runs wonderful on the STM32H750B-DK but the same code is going in Hard fault on Custom board.

I think the STM32H750B-DK uses MT48LC2M32B2 as SDRAM and I am Using IS42S32400F as SDRAM.

Before going ahead to TouchGFX which is another question.

 As the original question was about FMC example, what if you load that FMC example to the STM32H750B-DK board?

FMC Example through the same error as my custom board on the STM32H750B-DK.

Do you mean you are facing an issue with STM32H750B-DK with this example?:

Yes, I have cleaned the old installation files of STM32CUBEH7 Folder and cloned the above link specified by you , But the fresh FMC Code is sending out the same error
