Hi zhou

spf-28857 seems Sabre SD design, not ARD

Schematics
Design files, including hardware schematics, Gerbers, and OrCAD files
for i.MX 6QuadPlus (i.MX 6DualPlus emulation) (REV 1)

i.MX 6QuadPlus SABRE Development Board|NXP 

Note nxp does not support qnx, it is supported by qnx support directly.
