i.MX8-mini mmap()

[ristohedman]

Hi,

Could it be possible to access M4 DDR area from Linux user space with mmap() or related? I need a SHM- area between M4 and A53 and am searching a minimum effort solution to realize that.

Hi,

   To communicate between A53 & M4, you need to use rpmsg, we provide the corresponding driver and test program, you can get relevant information in i.MX_Reference_Manual.pdf and i.MX_Linux_Users_Guide.pdf.

Hope this informatin is helpful to you.

Have a nice day!

B.R,
