stm32 cube bug working with STM32F767ZG first reported in 2021 how to get progress?

[arro239]

stm32cube software is unable to program over 512Kb of binary into STM32F767ZG which is a 1MB part due to wrong identification as 2MB part

We first reported this back in 2021 as https://github.com/STMicroelectronics/STM32Cube_MCU_Overall_Offer/issues/11 and https://community.st.com/s/question/0D53W00001EEBXXSA5/stm32cubeprogrammer-incorrectly-erases-on-dual-bank-1mb-stm32f7

best we got so far is "i have also transmitted your issue to our development team with the internal reference 120183"

looking for ideas on how to make progress with this issue? we really like cube and our firmware is above 512Kb now

>>looking for ideas on how to make progress with this issue?

Have you tried other size Optimiced compiler options?

does this happen to you when flashing directly from cubeIDE?

Have you tried openocd?

[arro239]

Yes, same issue directly via cubeIDE.

We use DFU for device update in the field and openocd does not support DFU to the best of my knowledge. Do you know any alternative command like DFU windows implementations?

[Javier1]

youre right, i forgot about the DFU part

If you are sure the problem is in the stm32 part let it be, but otherwise you could try your own implementation of DFU host https://github.com/kiibohd/dfu-util

Hello @arro239 ,

The DFU programming issue on STM32F767xx MCUs is fixed in STM32CubeProgramer V2.16.0.

Could you please try with this version and let me know if the issue is solved or not?

Thank you for your contribution in STCommunity.
