Thanks Robin, A couple additional questions/comments: 1) I used Mender to update the FS and it seemed to work so I issued the commit command. Now, I'm having trouble with "uhd_find_devices" not finding anything and so I'm wondering how I go about swapping back to the previous partition? 2) I have found that the provided USB cable (for serial connection) has a molded collar that interferes with the N310 case and prevents proper seating. If the N310 case was not on, it would likely be fine. I modifed the USB cable by cutting back the molded collar and now it seems to behave fine.
