Having chalenges uploading to the STM32H747i_DISCO demo board

Duckpaddle · ‎2025-08-26

Hoping someone could help. I did a full erase on the stm32h747i_disco from the stm32cube programmer. I attempted (several times) to upload the STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex and got the following error:

14:09:58 : Opening and parsing file: STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex
14:09:58 : Memory Programming ...
14:09:58 : File : STM32Cube_Demo-STM32H747I-DISCO-V1.0.0_FULL.hex

14:10:00 : Address : 0x08000000

14:10:05 : Memory [0x08000000 : 0x08200000] - Checksum : 0x139CE03C

Does anyone have a suggestion?

Hello,

Did you enable the flash loader of the external QSPI memory before uploading the hex file??

The part of the graphics in that demo is located in the external memory (QSPI).

Hello @Duckpaddle

Which CubeProgrammer version used? Make sure to use the latest one.

Check the flash bank mode in the configuration settings.

Please have a look at this post that may help you.

If possible, share the log file.

Thank you for your quick response.

I am using the v2.20.0 version of the STM32CubeProgrammer. I have attached as a screen shot. I have also attached the log file where I attempted to program the board twice.

I am using the Demo Hex file from ST Micro for this board.

Thank you again for your help,

George

Thanks,

The log file at level 0 doesn't show much information but I had the doubt you didn't enable the external flash loader. So I tried to reproduce the behavior without enabling the flash loader and had almost the same log.

If you increase the verbosity level in the CubeProgrammer to 2 or 3 you can see there is an issue while programming at the address 0x90000000:
