Unable to program my GPIO image on STM32H750B-DK

Hi ,

I am not sure but my development board STM32H750B-DK may have some issues and I need some help to find what it may be .

As per the readme.txt (there is very less literature that I could find on this board) , I could dump the ext_mem boot bin into the Internal flash and I did not face any issue there. I am now trying to flash the IO toggle image onto the QSPI flash present on the development board and I always face the same error. I feel that there maybe a hardware issue on the board but I could be wrong. Your help is highly appreciated.

I have attached the error image.

The NOR Flash (the first one).

B01 version: https://www.st.com/resource/en/schematic_pack/mb1381-h750xb-b01-schematic.pdf

Hope it helps.

Can you connect to the board with CubeProgrammer and read from the internal flash?

if you want to download the image into the QSPI, please make sure you have selected the external flash loader. Are you successfully download the image into the external flash before?

Hello @nsingh and welcome to the community,

Make sure you uploaded first the external boot firmware from Projects\STM32H750B-DK\Templates\ExtMem_Boot

Then upload the GPIO toggle example from: Projects\STM32H750B-DK\Examples\GPIO\GPIO_IOToggle

Thanks for your responses.

I am not sure what is my external loader supposed to be . With the version 2.17 of the programmer , I could not find the external loader for STM32H750B-DK . Which one should I choose. I tried the second one but I still could not flash the image although I could fully erase the external flash. Also, is it possible to get schematics of this board ?
