The design tools for the i.MX6 SABRE SD board were OrCAD and Allegro, so, only these .dsn and .brd files are available on our side.
Unfortunately, there seems to be no easy way of converting .brd to .pcb files. Seems that you should have both Allegro and PADS tools installed to make the conversion. For more information, please refer to attached file.
Have a great day,
Artur
