Ok there is an order in that you need to do things. If you do any upgrading before expanding the drive it will no longer let you expand. So first you need to do an new image on your Micro card and do the setup. then go to advance settings do the Grow file system. reboot chose the drive to be mounted reboot and after, finish upgrading if needed, as you now can get 2.7.2 as a new image. If you are working on any videos (projectors) upgrading to the master branch for testing. Also this is an Falcon issue Not so much an Xlights. Posting on their forum you'll get better response. Don't take that the wrong way We are all here to help on all forums Ok all but Facebook. LOL
