Hello,

I am trying to generate my own image Distribution package for my DK2 board.

How to assign hardware cryp1/hash1 to A7 kernel?

Do I need to modify some .dts files? Or do I have to enable some options in menu config?

Give me please step-by-step recomendations if it is possible.

Thank you.

Hi,

I have added these lines to the end of the file "stm32mp157c-dk2.dts":

Than I clean and build the image again

bitbake st-image-weston -c cleanall
bitbake st-image-weston

And download basic image to the DK2 board using STM32CubeProg.

Unfortunately there are no any cryp devices in /dev/
