You may try to download and use the latest STM32CubeProgrammer v2.14.0 to see if the STM32H750B-DK is OK or not from hardware point of view.

[ZExpo.1]

Yes, I have tried that also, I re-installed everything from scratch now.

[jiangfan]

OK, be sure to enable the correct external loader: MT25TL01G_STM32H750B-DISCO for STM32CubeProgrammer to do the programming.

[ZExpo.1]

I have selected the Loader according to your specifications as shown

Now I format the Internal And External Memories accordingly as shown without any errors

Now i program the STM32H750B-DK With STM32CUBEIDE and get this message

[jiangfan]

You may try:

1) generate .hex file with STM32CUBEIDE

2) program the .hex file with STM32CubeProgrammer. You may get feedback if program is OK or not.

3) if step 2) OK, you may see if the .hex works as you expected

the purpose is to ensure your STM32H750B-DISCO is OK from hardware point of view.

I followed your steps and The System seems to be working perfectly fine.
I made a simple Blinky Project and it worked as expected.

Is there any way to test the external Flash? There are 2 Flash NOR Memory , Can we test it individually?

[jiangfan]

So, your board is good if the firmware is in internal flash only.

You may try to program the ST-LINK_GDB_server_a05624.srec (mentioned in your 1st post) with STM32CubeProgrammer:

1) program the .srec binary file with STM32CubeProgrammer. You may get feedback if program is OK or not.

2) if step 1) OK, you may see if the .srec works as you expected

the purpose is to ensure your STM32H750B-DISCO is OK from hardware point of view, especially the NOR flash starting from 0x90000000.

[ZExpo.1]

I am unable to find any .srec File in the touchgfx build Folder!

[jiangfan]

You may change setting to generate .hex file:
