How to Save and Install a New Image (Compact)

Before you load the new image onto your RevPi Compact, 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.

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:

Hardware

  • Your PC
  • Power supply unit
  • Cable USB 2.0 type A plug > USB 2.0 type micro B plug
  • Flash drive

Software

Download the files/programmes below and install the programmes on your PC:

Let’s go!

Backing up the old image on a USB stick

  • Connect the RevPi Compact’s micro-USB port with a USB A port on your PC.
  • Open RPi boot.
RPI Startfenster
RPi Startwindow
  • Connect your RevPi Compact with the power supply

RPi Boot is now searching for your RevPi Compact. The following window opens:

Your RevPi Compact has now been recognised.

  • Click on “Continue without check”

 

With some operating systems this way does not work. If this is the case for you, try the following way:

  • Connect the mini-USB socket of the RevPi Compact with a USB A socket of your PC.
  • Connect your RevPi Compact to the power supply.
  • Open RPi Boot.

RPIBoot reports either the “failed to claim” or “sending bootcode” error.

  • Unplug the USB cable and plug it in again immediately. Just let the RPI-Boot run and do not touch the power supply.

At the place where the red arrow in the screenshot points to, the USB plug was pulled out and plugged in again:


Your RevPi Compact has now been recognized and logs on as a drive shortly afterwards. Now you can continue as described before.

  • Click on “Continue without checking”.
  • Open Win32 Disk Imager.

  • When the “Matched!” dialogue is shown then the image is correct.

NOTE
While the USB plug is connected to your RevPi Compact, it is in flash mode and cannot be rebooted to run mode. First remove the USB cable and then restart RevPi Compact

 

If you are using Stretch as your image, you will be asked which RevPi device you are using the first time you log in.

  • Specify that you are using a RevPi Compact The data you need for RevPi Compact is then stored in the image. If you leave the wrong device, it is possible that your device is not working properly.
  • You need to log in on your RevPi Compact once.

At the first login, the login name is pi and the password is raspberry. The German keyboard layout is set for your device. Since this layout changes regionally, you may need to change the user name:

Keyboard layout by countryUsername
Germany/Austriaraspberry
Denmark, UK, USAraspberrz
France, Belgiumraspberrw

If you are using Stretch, you will first be asked which RevPi device you are using.

  • Enter the serial number and MAC address shown on the orange front Panel.

(1) MAC address, (2) Serial number

The password for the next login is automatically reset to the default password on the sticker on the side of the RevPi.

  • Restart the RevPi with sudo reboot. It can only be used to its full extent after the restart.
