Update the Firmware on your Raspberry Pi

In order to update the firmware you will need to log in as the root user using the following command:

sudo su

Then install the update tool:

sudo apt-get install rpi-update

Now update the firmware:

Finally, once the firmware has finished updating you will need to reboot your Raspberry Pi in order to load the new software. Wait until prompted and then select to reboot the device.

Update the Kernel on your Raspberry Pi

First you need to synchronise the database of available software packages and the available versions using the following command:

sudo apt-get update

Then you need to upgrade the packages with updates:

sudo apt-get upgrade

Image your Raspberry Pi

Once your Raspberry Pi has been updated you can image it, that way if your Pi crashes or your SD card becomes corrupt you have a backup.

To get started, remove your SD card and connect it up to a computer

Open Win32DiskImager. If you don’t have it installed you can download it from http://sourceforge.net/projects/win32diskimager/.

In the Image File input box enter the file path of where you would like to save your image. E.g. C:\Users\Amanda\Desktop\myrpi.img

Then select the device (your SD Card) that you would like to take an image of and click ‘Read’ to start creating the image.

When finished, eject your SD Card before removing it.
