I have a Digilent Zybo z7-20 board and I took the Linux base vivado project and compiled the petalinux from Digilent's GitHub . The os is working fine.
I observed a dvi2rgb block which terminates in video memory access and also, in petalinux repo, it's specified that there is a hdmi in via uio.
My question is: how can I get a picture from hdmi via user space io?
Thank you!Merry Christmas!

Yeah, mmap would work. To be honest, I want a simple example which work. Then, I could change my code to integrate it into my app.
Thank you for your response!
