Is it possible to write a non-blank media with Win32 disk imager?  I had to attempt to format the SD-Card before I could write the image.  Windows complained that it could not format the SD-Card, but then Win32 Disk Imager was able to write it.

Check the md5sum against the expected one. The md5sum value is usually posted separately.  It could be in a forum, on a website or contained in a separate file. The cd12a526ecdb34c12b4a737044e867e7 value is the checksum that verifies the file transferred correctly.

This tutorial is for Windows users. See Step-by-step Ubuntu SD Card Setup for Linux/Mac version.

Prerequisites & Tools

  • SD-Card & SD-Card reader/writer
  • 7-Zip to extract the SD-Card image from downloaded .xz file
  • Win32 Disk Imager to write the .img file to your SD-Card.
  • (optional) md5sums program can calculate checksums: MD5Sums Project
  • (optional) SD card format utility SDFormatter

Step-by-Step

  1. Download a compressed SD image (odroidu2_xxxxyyzz-linaro-ubuntu-desktop-uSDeMMC.img.xz) from: http://odroid.us/odroid/odroidu2/ubuntu/
  2. (optional) Check md5sum of the downloaded .xz archive
    1. Note the MD5 sum of the image on server in the .md5sum file: odroidu2_xxxxyyzz-linaro-ubuntu-desktop-uSDeMMC.img.xz.md5sum
    2. Calculate your md5sum for downloaded file 
       md5sums odroidu2_xxxxyyzz-linaro-ubuntu-desktop-uSDeMMC.img.xz
    3. Verify if the MD5 checksums match - if not, your downloaded file is corrupted, download again!
  3. Extract the .img file from .xz archive using 7-Zip
    7z -z odroidu2_xxxxyyzz-linaro-ubuntu-desktop-uSDeMMC.img.xz
  4. Plug your SD-Card to your SD reader/writer.
  5. Format the SD-Card using default Windows format utility or SDFormatter
    Warning: Make double sure you know which device represents the SD-Card. Formatting an incorrect drive will erase all data!
  6. Use the Win32 Disk Imager GUI to select the SD-Card image file (.img) and write it.
  7. All done - Plug the SD-Card into Odroid and boot!
