Paul, You can see on our schematics that the hinged sdhc card slot is an assembly option and not the default. https://wiki.solid-run.com/lib/exe/fetch.php?media=imx6:cubox-i:schematics-rev-1.1:cubox-i-lower.pdf You have either an initial early developer unit (pre-production) that was assembled like this for testing, or a unit that someone specifically ordered assembled this way. You can see from the schematic that this option does not have a CD-pin because it is meant to be a more permanent storage option. That being said, this is not a default option and therefore should not be merged into the mainline device-tree. Our soms and carriers are designed to be very flexible regarding the assembly options and we try to mainline device-tree files that represent the most common assembly options. Once there is a common accepted mainlining for device-tree fragments for overlays, that would be the proper place to make this change. Although in this case you would also need a custom u-boot so it is probably best to just handle the change there. If you would like touch base with me off list and I can point you at the required u-boot changes. Thanks, Jon
