Mbed OS vs STM32F745-DISCO board

I have this board

https://www.digikey.com/product-detail/en/stmicroelectronics/STM32H745I-DISCO/497-19507-ND/10244391

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)
https://os.mbed.com/platforms/ST-Discovery-H747I/
https://os.mbed.com/platforms/ST-Discovery-H745I/

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.

Hi

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:
https://github.com/AGlass0fMilk/marquesas-bsp/blob/master/custom_targets.json

“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!
