Setup instructions

  • You need an SDHC card with a minimum size of 4 GB. The image has a size of 4,000,000,000 bytes. We recommend a fast SD card as it expedites I/O operations. See: [1].
  • You need a PC with an SD card slot.
  • Download the selected image.
Linux instructions
  • Decompress the downloaded image: bunzip2 <image>.bin.bz2 (or use any GUI tool to unpack).
  • Decompressing will leave you the file <image>.bin.
  • Plug in the SD card.
  • Find out the SD card block device file, e.g. by entering dmesg after inserting the card. On most PCs, it is either sdx (last letter varies!) or mmcblk6 (number varies!). Double check this! You may corrupt your PC's hard disc if you take the wrong device!
  • If the automounter automatically mounts the SD card, unmount it. Check with mount.
  • Write the image to the SD card (this makes a bit-wise copy): sudo dd if=<image>.bin of=/dev/sdx bs=1M
  • To be on the safe side, do a sync.
  • The SD card is ready!
Windows instructions
  • Decompress the downloaded image with the program of your choice. Note you need an external tool to handle bzip2-compressed files, e.g. 7Zip.
  • To program the image to the SD card using a Windows PC, have a look here.
Continue
  • Put the SD Card into the CM-i.MX6 SD slot and adjust boot mode settings. For setting the DEV-i.MX6 DIP-switches for SD-boot see here.
  • Supply power to your board, and switch it on if necessary.


We recommend to connect
  • Wide screen monitor via HDMI cable
  • USB mouse
  • USB keyboard
  • Ethernet (If DHCP is available, Ubuntu will use it to get an IP address.)
    • If an Ethernet connection is available, the system time in Ubuntu will be synchronized automatically with an NTP server.

SD Card backup (Image creation)

If you customized the running image and want to create a binary image from the SD card, use the following instructions.

  1. Shut down the running target.
  2. Insert the SD card into the slot of your Linux PC.
  3. If any partition of the SD cards gets auto-mounted, please unmount it (Check with mount command).
  4. Draw the image
dd if=/dev/sdX of=sdcard-image-customized.bin bs=512 count=7000014
Note /dev/sdX is the block device file of your SD card.
5. Optionally, compress it: 
bzip2 sdcard-image-customized.bin
