Backing up SD card for microzed

Postby Guest »

Hi


I have currently installed the latest xillinux OS on a 7020 Microzed Board. These were links used to install
http://xillybus.com/downloads/xillinux-1.3.img.gz
http://xillybus.com/downloads/xillinux- ... d-1.3c.zip

I followed the instructions given here (http://xillybus.com/downloads/doc/xilly ... d_zynq.pdf) to install the OS on the microzed board. Iused the USB image kit version 1.61 in windows 8.

There was no issues burning the image into the SD card and booting the system on microzed. But, after working on the system, writing code, configurations, etc, I wanted to take a backup of the entire SD card (both partitions). So, I tried to use the USB Image kit version 1.61 to create a backup image in the img.gz format. I was able to create this backup image. But, now when I mount this new backup image again in device using the USB image kit software on another SD card, the mounting takes for ever, and after like 10 minutes, there is an error generated with error code 0 saying that Could not access the USB device (Code:0).

I also tried to mount the image created using win32disk imager software. After the image is mounted, and I try to open the SD card, it says SD card needs to be formatted.

Can anyone suggest me how to backup a SD card completely (Both partitions) and mount it in a another SD card. Which software would you recommend ? What is the best way of doing it ?

Hello,

It's quite odd that your attempts failed -- these imager tools are intended exactly for this.

Personally, I use plain cat or dd in Linux to create and write back images, but this involves writing to /dev/sdX files, with the risk of wiping the computer's hard disk if I accidentally pick the wrong file.

But I suppose you're asking about tools for Windows.

I would guess that the tools are OK, but that there's a confusion between backing up and/or restoring the entire SD card vs. a partition on the virtual disk it presents. By default, these tools aim at partitions. That could explain your repeated failure.

Regards,
Eli
