Hi,
Very sorry!
We only provide design files based on Cadence orCAD format. However, customers can use the file-->import function of Altium Designer to do format conversion and convert .DSN files to AD format files.
[note]
So far, i.MX8MP EVK has not been officially released, and its design files cannot be downloaded from the official website.
Have a nice day!
B.R,
