[[https://www.raspberrypi.org/products/raspberry-pi-4-model-b/|Raspberry Pi 4 Model B]] is a popular single board computer developed with the intention of promoting teaching of basic computer science in schools. It is a successor to Raspberry Pi 3 Model B+ with better processor and ability to drive multiple displays. Both stable and "testing" images are available for Raspberry Pi 4 Model B.

Raspberry Pi recommends creating a bootable SD card with the [[https://www.raspberrypi.com/documentation/computers/getting-started.html#raspberry-pi-imager|Raspberry Pi Imager]] (rpi-imager), their official cross-platform utility that downloads an image and writes it to removable media. !FreedomBox "stable" and "testing" images can be selected in rpi-imager under the "Other specific-purpose OS" category.
|
|
|
|
!FreedomBox SD card [[FreedomBox/Download|images]] for this hardware are also available online. Download the "stable" or "testing" image for Raspberry Pi 4 Model B. Follow the instructions on the [[FreedomBox/Download|download]] page to create a !FreedomBox SD card or USB drive and boot into !FreedomBox.

=== Booting from USB ===
|
|
|
|
MicroSD cards are notouriously slow and prone to be corrupted. SD card corruption means that a high read/write load or a sudden power outage can make render your card unusable. It is therefore strongly recommended that you use a USB drive for your root partition. To be able to do that, you have to follow these preliminary steps:
|
|
|
|
1. [[https://www.raspberrypi.com/software/|Download]] and install the Raspberry Pi Imager.
|
|
2. Insert a microSD card to your computer.
|
|
3. Open the Raspberry Pi Imager
|
|
3.1 Select '''CHOOSE OS''' >> '''Misc utility images''' >> '''Bootloader''' >> '''USB Boot'''
|
|
|
|
3.2 From '''CHOOSE STORAGE''' select your microSD card
|
|
|
|
3.3 Click on '''WRITE'''
|
|
|
|
4. After the writing was succesful, you should eject the card.
|
|
5. Insert the newly created card into your Raspberry Pi and boot up the device. If it is connected to a monitor, you will see a green screen. Let your device rest for a minute, after which you can disconnect it from power and eject the card from the Raspberry Pi. It can now boot from USB.
|
|
6. Final step: write your !FreedomBox image into your USB device, then connect it to your Raspberry Pi. Make sure you did not leave your microSD card in the Raspberry Pi.
|
|
|
|
Please note that steps 1. to 5. only need to be done once.
