I also got out the reference manual and looked up the section on CCM. It does not look like anything is being linked into this 64K. Perhaps I should put some of the static objects into it.

Re: I would like to use the Arduino IDE with the DE10-Nano Development Kit
it's not stm32 based, so this board is not a proper place to ask about it
