We have a use case for remote access of the microsd on the cube. Basically, the pixhawk is in a cabinet and access is a pain. Not to mention that we have worn out at least one microsd slot (thanks in part to poor handling) and would like to save wear on these by using a replaceable extension.
The problem is that OTS ribbon extensions don’t seem to work, the cube won’t recognize cards plugged in (or at least I get continuous bad logging from ardupilot). I’m not sure if this is a hardware limit with the cube, or a software thing with ardupilot (hoping for this). But I would welcome comments from someone who has solved this, knows a path to solving it, knows that its just not possible, or who may have another solution.
