How to Save and Install a New Image

Before you load the new image onto your RevPi Connect, we recommend that you back up the data that is important for you. There are several ways to back up your data. In this tutorial we will show you how to save an image on a USB stick. You can also save the image on the hard disk of your PC or an external hard disk.

Important! The image can only be copied if the watchdog is deactivated by the jumper on terminals 6 and 7!

In this tutorial we will work with a Windows PC. Of course, this also works with Linux. You can find tools and help on the homepage of Raspberry Pi.

You need:

Let’s go!

Backing up the old image on a USB stick

The following window will open:

• Click on the File button.
• Select a file in which the image should be saved.
• Write in the file name at the end of the selection. The name has to end in “.img”.

• Unzip the download
• Open WinMD5Free
• Select the file of the new image
• The program starts calculating the MD5 checksum

• After a few seconds the calculated checksum is displayed
• Open the *.MD5 file from the unpacked download with an editor. The file is e.g. 2017-05-31-revpi-jessie.md5
• Copy the MD5 sum and paste it into the field “Original file MD5 checksum value …” and click on the button “Verify”.
