MBED on propriatery board

Hi
We are creating our own board with ARm-Cortex-M4
I would like to verify that MBEd-OS run on any board (or only on a set of boards)
Can I use MBEd-ON and the development tool on our own developed board?

Thanks
Eli

yes, this will work. There is also a documented way for using custom targets:
https://os.mbed.com/docs/mbed-os/v5.15/reference/adding-and-configuring-targets.html

Thanks for your prompt reply !

  Can you just outline for me what is needed for the porting (a

very hugh level description)

Thanks again

Eli
