STM32H745I-DISCO factory reset

[mf123]

I purchased a STM32H745I-DISCO. The board appears to work fine. I am trying to flash the stock firmware onto the board. I downloaded the binary from the ST product page, followed the instructions, set the correct option bytes, used the external loader. The binary file on the product page "STM32Cube_Demo-STM32H745I-DISCO-V1.0.0_FULL.hex" does not bring the board back to factory settings. The touchscreen does not work. The stock demo wont run. Does anyone have have a more up to date binary file or procedure for factory reset?

Thanks

Hello,

please download the attached file.

You have to flash it with the STM32Cubeprogrammer using the MT25TL01G_STM32H745I-DISCO external loader.

You can use the GUI to flash the hex file after ensuring you've selected the right external loader:

or execute the command line while you're in the STM32CubeProgrammer\bin folder :

STM32_Programmer_CLI.exe -c port=SWD mode=UR -el ExternalLoader\MT25TL01G_STM32H745I-DISCO.stldr -d Your_path\STM32Cube_Demo-STM32H745I-DISCO-V1.1.0_FULL_V4.hex -v -hardrst

Please let me know whether it helps.
