I've also had a problem with SD copying. Using fedora 9, I took the 512MB
development SD card and tried to make a copy onto a new 2GB SanDisk SD card.
I did the following:
Insert my golden SD card
dd if=/dev/sdb of=/dev/myfilename.dd
Insert my blank SD card
dd if=/dev/myfilename.dd of=/dev/sdb
Here is the hyperterminal output when I boot from the new SD card:
Finished booting in 1.71 seconds
Type 'tshelp' for help
$ exit
>> Booting Linux...
pivot_root: pivot_root: No such file or directory
/linuxrc: 47: bin/mount: not found
/linuxrc: 48: bin/mount: not found
/linuxrc: 49: cannot open ./dev/ttyAM0: No such file
It worked when I did the dd command onto a separate 512MB SD card that came
from Technologic Systems, but it never worked on 3 separate SD cards that I
purchased at the store.
Any ideas?
Thanks,
Steve
