# Running Serenity on Raspberry Pi
|
|
|
|
## NOTE
|
|
|
|
This is for development purposes only - Serenity doesn't currently boot on Rasperry Pi! Use this guide if you want to set up a development environment.
|
|
|
|
Currently only UART output is supported, no display.
|
|
|
|
64-bit only, so you need a Rasperry Pi 3 or newer.
|
|
|
|
## Running in QEMU
|
|
|
|
### Step 1: Set Up Serenity
|
|
|
|
Please follow [build instructions](BuildInstructions.md) to download and build Serenity. Make sure everything builds successfully for x86.
|
|
|
|
### Step 2: Build Aarch64 toolchain
|
|
|
|
Use following the command to build the toolchain for Aarch64:
|
|
|
|
```console
|
|
Meta/serenity.sh rebuild-toolchain aarch64
|
|
```
|
|
|
|
### Step 3: Build and run in emulator
|
|
|
|
Use the following command to build and run the Aarch64 kernel:
|
|
|
|
```console
|
|
Meta/serenity.sh run aarch64
|
|
```
|
|
|
|
It should build Serenity and open a QEMU window, similar to the x86 version. You should see some messages in the terminal.
|
|
|
|
You can also run it under gdb with:
|
|
|
|
```console
|
|
Meta/serenity.sh gdb aarch64
|
|
```
|
|
|
|
## Running on real hardware using an SD Card
|
|
|
|
### Step 0: Download and run Raspberry Pi OS from an SD Card
|
|
|
|
This step is needed because the original firmware files need to be present on the SD Card when booting Serenity. It will also help with the UART setup.
|
|
|
|
### Step 1: Connect your Raspberry Pi to your PC using a UART cable
|
|
|
|
Please follow one of the existing guides (for example [here](https://scribles.net/setting-up-serial-communication-between-raspberry-pi-and-pc)) and make sure UART is working on Raspberry Pi OS before proceeding.
|
|
|
|
### Step 2: Mount SD Card
|
|
|
|
If you use a Raspberry Pi 4, and your serenity kernel is called `kernel8.img`
|
|
(the default), and you don't have any other `kernel*.img` files on your SD
|
|
card, make sure `config.txt` is empty.
|
|
|
|
If you want to use filename that isn't `kernel8.img` or if you want to keep
|
|
other `kernel*.img` files on your SD card, put this in config.txt:
|
|
|
|
```
|
|
arm_64bit=1
|
|
kernel=myfilename.img
|
|
```
|
|
|
|
If you use a Raspberry Pi 3, put this in config.txt:
|
|
|
|
```
|
|
enable_uart=1
|
|
```
|
|
|
|
### Step 3: Copy Serenity kernel to SD Card
|
|
|
|
`kernel8.img` can be found in `Build/aarch64/Kernel/Prekernel/`. Copy it to the main directory on the `Boot/` partition, next to `config.txt`. You can either replace the original file or use another name (see above).
|
|
|
|
### Step 4: Put the SD Card in the Raspberry Pi and power on
|
|
|
|
You should start seeing some messages in your UART terminal window.
|
|
|
|
## Running on real hardware using network (Raspberry Pi 3)
|
|
|
|
### Prerequisites
|
|
|
|
There are multiple ways to set up your network. The easiest way is a direct connection between the Raspberry Pi and your PC. To achieve this your PC has to have an Ethernet port.
|
|
|
|
Here's the [Raspberry Pi Documentation](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#debugging-network-boot-mode) on booting from the network.
|
|
|
|
### Step 1: Make sure OTP mode is enabled on the board
|
|
|
|
This is enabled by default on Raspberry Pi 3+. For the previous boards please see the section [Debugging Network Boot Mode](https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#debugging-network-boot-mode) of the Raspberry Pi documentation.
|
|
|
|
### Step 2: Copy all files from the original SD Card to your PC
|
|
|
|
This directory will serve as a TFTP server, sending files to the Raspberry Pi when requested.
|
|
|
|
### Step 2: Set up the network interface
|
|
|
|
Switch the network interface to static mode (static IP) and disable the firewall.
|
|
|
|
### Step 3: Set up network services
|
|
|
|
Booting Raspberry Pi requires DHCP and TFTP servers.
|
|
|
|
On Windows, you can use the [Tftpd32](https://bitbucket.org/phjounin/tftpd64/src/master/) program.
|
|
|
|
Example configuration for DHCP:
|
|
|
|
|
|
|
|
Make sure you **disable** the `Ping address before assignment` option.
|
|
|
|
Example configuration for TFTP:
|
|
|
|
|
|
|
|
The only option worth noting is `Base Directory` which should contain the files from the SD Card.
|
|
|
|
### Step 4: Power up the Raspberry Pi
|
|
|
|
Remove the SD Card, connect an Ethernet cable between the Raspberry Pi and your PC and power on the board.
|
|
|
|
After 5-10 seconds you should see files being served by the TFTP server:
|
|
|
|
|
|
|
|
The system should boot normally as it would from the SD Card.
|
|
|
|
### Step 5: Modify config.txt and copy Serenity kernel
|
|
|
|
Similarly to booting from SD Card (see above), modify `config.txt` and copy the Serenity kernel to the TFTP directory.
|
|
|
|
### Step 6: Reset Raspberry Pi
|
|
|
|
You should start seeing some Serenity messages in your UART terminal window.
