i have a Dragonboard and a STM32F446 mezzanine board.
i removed JP5 on the mezz board to enable communication via internal connectors and i got STLink to detect the mezzanine board, but not more.
My main problem is: i don’t understand how these two boards can be used together?
How can i make these two boards communicate with each other?
Which software is needed?
How can i read the additional sensors on the mezzanine card from my Dragonboard (Linaro based)?
I tried to find any documentation, but couldn’t find any answers in it so far.
Any help is really appreciated!
