just an update, I got it working up to the point where I can now capture data. The images are distorted though, I'm currently reviewing all the registers again.
I also had to guess on the base location of CPMEM, I cannot find it on the reference manual. It seems that 0x270_0000 works for me, I hope I can get some better information on this one
I'm using i.MX6Q (MCIMX6Q6AVT10AC)
