It appears that I was also confused about the different models in the CuBox-i line. I had assumed that the models had been updated to a new revision (carrying that 1.5 SOM) since the time I bought mine (which was thus some sort of first generation). With this scenario in mind, it made sense to me that a CD GPIO required only for the second generation would have been applied by mistake to all the cubox-i devices by having it in the common dtsi. I checked on the leaflet inside the box and models did not change, only the 4x4 model was added in the meantime. > We're also confused about "hinged micro SD card slot" - Cubox-i's > come with either a push-push slot or a static (push-in, pull-out) > slot. > (Prototypes were the latter.) The one I have definitely does not have a spring-loaded mechanism, so I would call it a push/pull static slot. I mentioned a hinged slot because that's the term used to describe the layout in the CuBox-i-Lower schematics, SD/MMC Connector part: "U3 is an internal hinged micro SD". Looking at pictures of what hinged slots look like, that's definitely not what I have here. Are all CuBox-i units that have ever been sold supposed to have a connector with a CD line? I find it hard to believe that it's broken specifically on mine. If that's really needed, I could open up the device, check whether the R8 pull is in place and check the voltage there.
