The FML13V05 hardware is designed for this. We can't change it.= =C2=A0 >>=C2=A0 >> I may not have been clear: an internal card slot does not necessarily >> mean the card is non-removable.

But the K3 SD card driver= need it, so the GPIO88 is tied low on board.=C2=A0 Sounds like you should use non-removable or broken-cd instead of cd-gpios.
