4. System Recovery
This chapter describes the steps to create a new SD/MMC card to boot up an ICM-
3011 board. When things go wrong, we could take this SD/MMC card as the backup
or the new system to start.
4.1. Download the SD image
Downloaded the SD card image: go to http://embux.github.io/product/embux-
products/ and choose the right image for your platform (in this case: ICM-
3011_Android), just click on it and it will start download immediately. Once
download has finished, you’ll have a .xz file (ex: icm-3011-android-5.0.2-full.img.xz ).
4.2. Write an SD/MMC Card using Linux (Ubuntu)

From the terminal run
df -h
.

Connect the SD card reader with the SD card inside.

Run
df -h
again and look for the new device that wasn't listed last time.
Record the device name of the filesystem's partition, for example:
/dev/sdc1.

Unmount the partition so that you will be allowed to overwrite the disk:
sudo unmount /dev/sdc1

Decompressed the xz file which download in sec 4.1
$ xz – d
ubuntu12-full.img.xz

In the terminal, write the image to the card with this command, using the
disk device name from above. Read the above step carefully to be sure you
use the correct disk number here: (This will take a few minutes)
$ sudo dd if=<image_path>/ubuntu12-full.img of=/dev/sdc bs=8M conv=fsync
