Where is STM32H735G-DK full .hex file as supplied from the factory?

SPefh.1 · ‎2021-03-11

There's a file STM32Cube_Demo-STM32H735G-DK-V1.0.0 on the website, but it's not the one referenced in the accompanying .bat file (which has a name ending in "FULL") and seems to just (sometimes) load up the selection screen but mostly gives me a blank screen, and any selection leads to a blank screen.

Is there a documented way to restore the board entirely to factory starting condition?

Hello,

the hex file is ok,

i had to modify "program_hexfile.bat"

it could not load the external loader file, because of the SPACE in "Program Files"

1. changed the path to my programmer directory

2. copy the external loader file "MX25LM51245G_STM32H735G-DK.stldr" from the prgrammer directory to the batch file directory.

3 changed the path of the external loader file in the batch file

...

:: C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer-2-6-0\bin\STM32_Programmer_CLI.exe

::@SET STM32_PROGRAMMER_PATH="%ProgramFiles(x86)%\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin"

@SET STM32_PROGRAMMER_PATH="C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer-2-6-0\bin"

...

::@SET STM32_EXT_FLASH_LOADER=%STM32_PROGRAMMER_PATH%\ExternalLoader\%EXT_LOADER2%.stldr

@SET STM32_EXT_FLASH_LOADER=%EXT_LOADER%.stldr

...

then you should get the following output freom the batch file

if you have still problems, post the batch file output

Thanks!

Still doesn't work from the bat file for some reason, but I got it to work by selecting the correct loader, erasing and programming it directly from the programmer (and putting SW1 in the right position).
