Hi,
New member here. I’ve had a BeagleBone for a couple of weeks and really like it. I’ve been running Ubuntu on it with great success. I wanted to duplicate the SD card as both a backup, and to have additional images that I can experiment on without having to lose the original.
I’ve been using dd in my Ubuntu laptop to copy the image. After inserting and unmounting the source SD I’ve done this:
dd if=/dev/sdc of=ubuntu_bone.img
That works fine. Then to write to an SD of the exact same size and make:
dd if=ubuntu_bone.img of=/dev/sdc
It takes a long time, but it succeeds. Unfortunately when I put the newly created SD copy in the BeagleBone it will not boot. No flashing lights or anything. So I take it out, put the source SD back in and it starts putting within a few seconds.
I tried some dd parms, like block size, for both the reading in and copying out, but it made no difference.
Any suggestions on what I may be missing or doing wrong would be greatly appreciated.
Thanks,
Jake
