TS-768x MicroSD Backup
|
Click to download the latest 4GB SD card image. |
Using another Linux workstation
Download the latest SD card image and write this image to an SD card. A USB MicroSD adapter can be used to access the card. First, you must find out which /dev/ device corresponds with your USB reader/writer.
Step 1 Option 1 (lsblk)
Newer distributions include a utility called "lsblk" which allows simple identification of the intended card:
lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sdY 8:0 0 400G 0 disk ├─sdY1 8:1 0 398G 0 part / ├─sdY2 8:2 0 1K 0 part └─sdY5 8:5 0 2G 0 part [SWAP] sr0 11:0 1 1024M 0 rom sdX 8:32 1 3.9G 0 disk ├─sdX1 8:33 1 7.9M 0 part ├─sdX2 8:34 1 2M 0 part ├─sdX3 8:35 1 2M 0 part └─sdX4 8:36 1 3.8G 0 part
In this case the SD card is 4GB, so sdX is the target device. Note that on your system, sdX will not be a real device, it could be sda, sdb, mmcblk0, etc. Technologic Systems is not responsible for any damages cause by using the improper device node for imaging an SD card.
Step 1 Option 2 (dmesg)
After plugging in the device, you can use dmesg to list
scsi 54:0:0:0: Direct-Access Generic Storage Device 0.00 PQ: 0 ANSI: 2 sd 54:0:0:0: Attached scsi generic sg2 type 0 sd 54:0:0:0: [sdX] 3862528 512-byte logical blocks: (3.97 GB/3.84 GiB)
In this case, sdXc is shown as a 3.97GB card. Note that on your system, sdX will not be a real device, it could be sda, sdb, mmcblk0, etc. Technologic Systems is not responsible for any damages cause by using the improper device node for imaging an SD card.
Step 2
Once you have the target /dev/ device you can use "dd" to backup/restore the card. To restore the board to stock, or rewrite to the latest SD image:
wget https://files.embeddedTS.com/ts-arm-sbc/ts-7682-linux/binaries/ts-images/ts768x-latest.dd.bz2
# Specify your block device instead of /dev/sdX
# Note that this is a whole disk image, so use /dev/sdX instead of
# using /dev/sdX1
bzcat ts768x-latest.dd.bz2 | dd conv=fsync bs=4M of=/dev/sdX
To take a backup of your entire SD card, you can switch the input file and the output file:
# Specify your block device instead of /dev/sdX
dd if=/dev/sdX conv=fsync bs=4M | bzip2 > backup.dd.bz2
