Mbed OS vs STM32F745-DISCO board

I have this board


As mounted via USB it shows an “mbed.htm” file in the virtual drive, which in turn says “it is not supported by mbed”

“mbed detect” does not detect a supported board

Website suggests I need the STM32H747-DISCO (747 good, 745 bad)

But, I see here that there is something about H745 support:

As a 100% newbie to mbed OS / mbed CLI, I think I just want to figure out if it’s a hard lift to get this board talking to mbed CLI or if I should just get the 747 board instead.



Few comments/answers:

“it is not supported by mbed”

Yes, STM32H745 disco target is not officially supported yet by Mbed.
But there is some solutions :slight_smile:

Have a look on https://os.mbed.com/docs/mbed-os/v6.2/program-setup/adding-and-configuring-targets.html

Since https://github.com/ARMmbed/mbed-os/pull/12801,
you can easily add the DISCO as a custom board like for ex:

“mbed detect” does not detect a supported board

Yes, targets is not supported yet in mbed_os-tools.
You can make a pull request like, for ex: https://github.com/ARMmbed/mbed-os-tools/pull/235

Finally, I would say that if you are able to port this STM32H745 disco target, maybe you could also push a pull request on mbed-os.
We will review it and merge it officially!
