BeagleBone Black Extracting eMMC contents
Fragment of a discussion from User talk:Jkridner
I'm not sure why 'dd' would have this limitation, but perhaps it does. I've added compression as the default to end-run the whole issue. It is possible I didn't build in large file support and I can look for that in the kernel build flags at some point. It seems pretty low priority to me since the compression should just work.
