I think you will have two problems. First, you can not put a 4GB file on a 4 GB card, because there must also be room for the Linux OS, and depending on the version, this can be another 1 GB, or more.
Second problem is that when you install a 2 GB image on a 4 GB card, the partition as installed is typically about 2 GB, and the rest of the card can not be used, until you expand the partition to the full size of the card. So, for working with the 4 GB eMMC version of the Beaglebone Black, you must use at least an 8 GB card. I use 16 GB, so that there is room for about three images that are not compressed. You can not go larger than 32 GB at this time. --- Graham == On Tuesday, December 2, 2014 5:57:16 PM UTC-6, br...@forceconstant.com wrote: > > So in that other thread, it was instructed to use the same dd command "dd > if=/dev/mmcblk1 of=/mnt/BeagleBoneBlack-eMMC-image-$RANDOM.img bs=10M" to > create image, so why would mine only end up 2GB instead of 4GB?
