Working on a design for a CM3, but I am including SD card provisions for a CM3 Lite since it looks like stock on the CM3 is limited currently.
I reviewed the schematic, and it appears that none of the SDX_x lines are terminated. Is there a particular reason why? All documentation i've come across regarding SD mentions termination resistors, and i have included it in past designs for other SoM PCB developments.
EDIT: I should clarify that this regarding the CMIO PCB reference design.
