I'm pretty new to working in UNIX, and have to do some development on the
TS-8390-4700 board. Before I get started I have to use an image provided by TS.
I need some help backing-up an existing micro SD card, and "dropping" an
imagine onto the same micro-SD card.
Here is a summary of what I have to do:
1. Back-up the existing micro-SD card (that came with the TS-8390-4700 board).
2. "Drop" a downloaded image onto the micro-SD card.
3. If necessary, how to revert the micro-SD card to the backed-up image.
Here's where I am, and what I still have to do:
1. Using the "sudo fdisk -l" command, I was able to see that the micro-SD card
had a few partitions on it (/dev/sdb1, /dev/sdb2, /dev/sdb3, /dev/sdb4). I then
used the command "sudo dd if=/dev/sdb of=sd.iso", which returned the following
result:
3862528+0 records in
3862528+0 records out
1977614336 bytes (2.0 GB) copied, 505.756 s, 3.9 MB/s
which looks like it got backed-up successfully to the .iso file. Is this the
best way to back-up/image the micro-SD card, so that I can revert ALL files and
partitions to the way it was?
2. The image I require is:
"ftp://ftp.embeddedarm.com/ts-socket-macrocontrollers/ts-4800-linux/binaries/ts-images/2gbsd-latest.dd.gz";
Once downloaded, how can I extract this image and "drop" it on the micro-SD
card? Can I use the 'dd' utility to do this? Or some other utility? Do I have
to format the micro-SD card first?
3. If I want to revert the micro-SD card back to the way it was before I
"dropped" the image onto it, how do I do that using the .iso type (or any file
type) using the 'dd' utility?
These questions may seem basic, but any help would be greatly appreciated!
Thanks in advance!
