Re: watch memory allocation c++ libraries SW4STM32

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.

I have read something about SPIclass but I can´t get it to work... Any hints?...

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

Which core do you use?

I just tested with my libmaple core, it prints

Code: Select all

c = -8000
d = 4000
