I have tried multiple times to flash the .bin file onto the STM32F746 Discovery using the ST link Utility and it does not work.

What .bin were you using? aka, what version?

Hi There,
I have the same issue, I flashed the latest 6.0.1 and also the 6.0.0 firmware, but unfortunatelly neither of them worked.
First I erased then the flash memory, then wrote these files with STM32 CubeProgrammer, the flash process was successful.
- adafruit-circuitpython-stm32f746g_discovery-en_US-6.0.0.bin
- adafruit-circuitpython-stm32f746g_discovery-en_US-6.0.1.bin

Note: previously I had MicroPython on this board, which worked.
When I plug in the board to a Windows PC I still see that drive name, what was set suring the MicroPython firmware upgrade process (DIS_746NG)

Do you Guys have any suggestion what can I do to make it work?
Thank you,
Robert

You could try the latest pre-release as well but it is unlikely to work. STM32F7 support isn't actively being maintained by Adafruit funded folks at the moment because Adafruit doesn't sell any boards with that chip family. I know of no others who are working on it.

Ok, I see, and I didn't know that.
Thanks anyways, I will try to install the latest pre-release.
I appreciate your help!
