 The ChangeLog deserves a separate mention:

- - Releases are listed in reverse chronological order order, so the
-   latest/next release is at the beginning of the file
- - Only *user-facing bugs and features* are detailed, so code refactor,
-   new tests, etc. are not listed.

+:lock_with_ink_pen: Signing Commits with GPG
+---------------------------------------------
+
+To ensure the authenticity and integrity of your contributions, we
+**require** all commits to be signed with GPG.  This cryptographically
+verifies that commits come from a trusted source.
+
+### Generating a GPG Key
+
+If you don't already have a GPG key, generate one:
+
+```bash
+$ gpg --full-generate-key
+```
+
+When prompted, choose:
+- Key type: `RSA and RSA` (default)
+- Key size: `4096` bits (recommended for security)
+- Expiration: `0` (key does not expire)
+- Real name and email: Use the same email as your Git configuration
+
+> [!NOTE]
+> We recommend keys that do not expire for signing commits.  Expiration
+> creates a "usability time bomb" without providing meaningful security
+> benefits for code signing.  See [this article][pgpfan] for details.
+
+### Configuring Git to Sign Commits
+
+First, find your GPG key ID:
+
+```bash
+$ gpg --list-secret-keys --keyid-format=long
+```
+
+Look for the line starting with `sec`, the key ID is the part after the `/`.
+For example, in `sec   rsa4096/ABCD1234EFGH5678`, the key ID is `ABCD1234EFGH5678`.
+
+Configure Git to use your GPG key:
+
+```bash
+$ git config --global user.signingkey ABCD1234EFGH5678
+$ git config --global commit.gpgsign true
+```
+
+The second command enables automatic signing for all commits.  Alternatively,
+you can sign individual commits with `git commit -S`.
+
+### Publishing Your Public Key
+
+To allow others to verify your signatures, publish your public key to a
+keyserver:
+
+```bash
+$ gpg --keyserver hkps://keys.openpgp.org --send-keys ABCD1234EFGH5678
+```
+
+> [!IMPORTANT]
+> The keyserver will send a verification email to the address associated
+> with your key.  You **must** click the link in that email to confirm
+> ownership before your key becomes searchable by email address.
+
+Alternative keyservers you can use:
+- `hkps://keyserver.ubuntu.com`
+- `hkps://pgp.mit.edu`
+
+### Adding Your GPG Key to GitHub
+
+For GitHub to show your commits as "Verified", you need to add your public
+key to your account:
+
+1. Export your public key:
+   ```bash
+   $ gpg --armor --export ABCD1234EFGH5678
+   ```
+
+2. Copy the entire output, including the `-----BEGIN PGP PUBLIC KEY BLOCK-----`
+   and `-----END PGP PUBLIC KEY BLOCK-----` lines.
+
+3. Go to [GitHub Settings → SSH and GPG keys](https://github.com/settings/keys)
+
+4. Click **New GPG key** and paste your public key.
+
+Now your signed commits will display a "Verified" badge on GitHub! :white_check_mark:
+
+For more details, see GitHub's [official documentation on commit signature verification][gpg-verify].

+Raspberry Pi 2 Model B
+======================
+
+The [Raspberry Pi 2 Model B][1] is a 32-bit ARM single-board computer,
+powered by the Broadcom BCM2836 quad-core Cortex-A7 processor @ 900 MHz
+with 1 GB RAM.
+
+The board features:
+
+- 4x USB 2.0 ports
+- Fast Ethernet (100 Mbps)
+- microSD card slot for storage
+- HDMI port
+- GPIO header (40-pin)
+
+> [!NOTE]
+> Revision 1.2 of the Pi 2B actually uses a BCM2837 (Cortex-A53) underclocked
+> and without WiFi, making it very similar to the Pi 3B hardware-wise but
+> running in 32-bit mode.  This revision is not supported.
+
+How to Build
+------------
+
+Since there are no pre-built images for ARM32, you need to build both Infix
+and the bootloader from source.
+
+
+1. Clone the repository
+
+        git clone https://github.com/kernelkit/infix.git
+        cd infix
+
+2. Build the bootloader (in separate tree)
+
+        make O=x-boot rpi2_boot_defconfig
+        make O=x-boot
+
+3. Build Infix (in another tree)
+
+        make O=x-arm32 aarch32_defconfig
+        make O=x-arm32
+
+4. Create the SD card image
+
+        ./utils/mkimage.sh -b x-boot -r x-arm32 raspberrypi-rpi2
+
+The resulting image can be found in `x-boot/images/infix-arm-sdcard.img`
+
+Flashing to SD Card
+-------------------
+
+[Flash the image][0] to a microSD card (at least 4 GB):
+
+```bash
+sudo dd if=x-boot/images/infix-arm-sdcard.img of=/dev/mmcblk0 \
+        bs=1M status=progress oflag=direct
+```
+
+You can also use `bmaptool`:
+
+```bash
+sudo bmaptool copy x-boot/images/infix-rpi2-sdcard.img /dev/mmcblk0
+```
+
+> [!WARNING]
+> Ensure `/dev/mmcblk0` is the correct device for your SD card and not used by
+> the host system! Use `lsblk` to verify.
+
+Booting the Board
+-----------------
+
+1. Insert the flashed SD card into the Raspberry Pi
+2. Connect an Ethernet cable (DHCP will be used to get an IP address)
+3. Power up the board using a 5V/2.5A micro-USB power supply
+
+The board will boot and obtain an IP address via DHCP on the Ethernet port.
+Find the assigned IP and SSH in with the default login credentials, user/pass:
+`admin` / `admin`.
+
+Console Port (Optional)
+-----------------------
+
+A serial console can be useful for debugging. Connect a USB-to-TTL
+serial adapter (3.3V) to GPIO pins:
+
+- GND → Pin 6, ground
+- TxD → Pin 8, GPIO 14
+- RxD → Pin 10, GPIO 15
+
+Serial settings: 115200 8N1
+
+> [!WARNING]
+> Use only 3.3V serial adapters. 5V adapters will damage your Raspberry Pi!

+
+### Default Network Configuration
+
+Infix comes preconfigured with:
+
+- **LAN ports** (lan1-lan4): Bridged for internal networking
+- **WAN port**: DHCP client enabled for internet connectivity
+- **SFP ports** (sfp1, sfp2): Available for configuration
+- **WiFi interfaces** (wifi0, wifi1): Available for configuration
+
+## Getting Started
+
+### Quick Start with SD Card
+
+The easiest way to get started is using an SD card:
+
+1. **Download the SD card image:** [infix-bpi-r3-sdcard.img][2]
+2. **Flash the image to an SD card:** see [this guide][0]
+3. **Set boot switches:**
+   - Set DIP switches to **0000** (SD card boot mode)
+   - Switch positions are on the underside of the board near the SD slot
+4. **Boot the board:**
+   - Insert the SD card
+   - Connect power
+   - Connect to LAN port or console (115200 8N1)
+   - Default login: `admin` / `admin`
+
+### Boot Switch Reference
+
+The BPI-R3 has a 4-position DIP switch that controls boot media:
+
+<img align="right" src="bootstrap-switch.webp" alt="DIP switches" width=200 padding=10>
+
+| Position | Mode        | Description                           |
+|----------|-------------|---------------------------------------|
+| 0000     | SD card     | Boot from microSD card (recommended)  |
+| 0110     | eMMC        | Boot from internal eMMC storage       |
+| 1010     | SPI NAND    | Boot from SPI NAND (advanced users)   |
+
+> [!NOTE]
+> Switch position is read from left to right: "0" = OFF, "1" = ON.  
+> When the DIP switch is in the "UP" position it is OFF(0).
+
+## Advanced: Installing to eMMC
+
+For production deployments or better performance, you can install Infix
+to the internal eMMC storage. This is more complex but provides faster
+boot times and eliminates the external SD card.
+
+### Why Use eMMC?
+
+**Advantages:**
+
+- Faster boot and better performance
+- No external SD card to manage
+- More robust for industrial/embedded deployments
+
+**Disadvantages:**
+
+- More complex installation process
+- Requires intermediate NAND boot step
+- Harder to recover from errors
+
+### Prerequisites
+
+- FTDI USB-to-serial cable (3.3V) for console access
+- microSD card with Infix (for initial boot)
+- USB flash drive (FAT32 formatted)
+- Downloaded files (see below)
+
+### Required Files
+
+Download and place these files on a FAT32-formatted USB drive:
+
+1. **Intermediate NAND bootloader** (from Frank-W's U-Boot):
+   - [bpi-r3_spim-nand_bl2.img][5] (BL2 loader)
+   - [bpi-r3_spim-nand_fip.bin][6] (FIP image)
+2. **Infix eMMC image:**
+   - [infix-bpi-r3-emmc.img][3] (Complete system image)
+3. **eMMC bootloader** (extracted from):
+   - [bpi-r3-emmc-boot-2025.01-latest.tar.gz][4]
+   - Extract `bl2.img` from the tarball to your USB drive
+
+> [!WARNING]
+> The following process involves multiple boot mode changes.  Take your
+> time verify each step carefully.
+
+### Installation Steps
+
+#### Step 1: Boot from SD card
+
+1. Set boot switches to **0000** (SD card mode)
+2. Insert SD card with Infix
+3. Power on and break into U-Boot (press Ctrl-C during boot)
+
+#### Step 2: Flash intermediate NAND bootloader
+
+This step installs a temporary bootloader to NAND that will help us
+flash the eMMC. From the U-Boot prompt:
+
+```
+usb start
+mtd erase spi-nand0
+fatload usb 0:1 0x50000000 bpi-r3_spim-nand_bl2.img
+mtd write spi-nand0 0x50000000 0x0 0x100000
+fatload usb 0:1 0x50000000 bpi-r3_spim-nand_fip.bin
+mtd write spi-nand0 0x50000000 0x380000 0x200000
+```
+
+#### Step 3: Boot from NAND
+
+1. Power off the board
+2. Set boot switches to **1010** (NAND mode)
+3. Power on - you should boot into U-Boot again
+
+#### Step 4: Write Infix image to eMMC
+
+From the U-Boot prompt:
+
+```
+usb start
+fatload usb 0:1 0x50000000 infix-bpi-r3-emmc.img
+setexpr blocks ${filesize} / 0x200
+mmc write 0x50000000 0x0 ${blocks}
+```
+
+This writes the complete Infix system (partitions, rootfs, etc.) to eMMC.
+
+#### Step 5: Configure eMMC boot
+
+Now configure the eMMC boot partition and write the bootloader:
+
+```
+mmc partconf 0 1 1 1
+mmc erase 0x0 0x400
+fatload usb 0:1 0x50000000 bl2.img
+mmc write 0x50000000 0x0 0x400
+mmc partconf 0 1 1 0
+```
+
+#### Step 6: Boot from eMMC
+
+1. Power off the board
+2. Set boot switches to **0110** (eMMC mode)
+3. Remove SD card (optional, but recommended to verify eMMC boot)
+4. Power on
+
+Your BPI-R3 should now boot Infix from internal eMMC storage!
+
+## Troubleshooting
+
+### Board won't boot
+
+- Verify boot switch positions (check twice!)
+- Ensure power supply provides adequate current (12V/2A recommended)
+- Try booting from SD card with switches at **0000**
+
+### Can't break into U-Boot
+
+- Ensure serial console is connected properly (115200 8N1, 3.3V)
+- Press Ctrl-C immediately when you see boot messages
+- Try power cycling and pressing Ctrl-C repeatedly
+
+### eMMC boot fails after installation
+
+- Boot from NAND (**1010**) and verify eMMC image was written
+- Check USB drive contents - ensure all files are present
+- Re-run Step 5 (eMMC boot configuration)
+
+### Reverting to SD card
+
+Simply set boot switches back to **0000** and boot from SD card. The
+eMMC installation does not affect SD card functionality.
+

+- [Official BPI-R3 Wiki][7]
+- [Release Downloads][8]
+
+## Building Custom Images
+
+See the main Infix documentation for building from source. To build both
+SD card and eMMC images locally:
+
+```bash
+# Build bootloaders for both SD and eMMC
+make x-bpi-r3-sd-boot
+make x-bpi-r3-emmc-boot
+
+# Build main system
+make aarch64
+
+# Create SD card image
+./utils/mkimage.sh -od bananapi-bpi-r3
+
+# Create eMMC image
+./utils/mkimage.sh -odt emmc bananapi-bpi-r3
+```

-# Raspberry Pi 3B/4B
+# Raspberry Pi 3B/4B/CM4

-## Support level
+## Overview

-Full support for base board but not any extension board on the GPIOs.
-Other RPi boards of the same generation may work as well, but may need
-some additional testing/work.  A few CM4 variants have been tested and
-seem to work as expected, but YMMV as always.
+The Raspberry Pi is one of the most popular single-board computers with full
+Infix support for networking features, making it an excellent platform for
+learning, prototyping, and lightweight network applications.

-### Touch screen
+### Hardware Features

-The [Raspberry Pi touch display v1][0] is supported on the 4B, including
-touch functionality.  There are multiple touchscreens on the market for
-Raspberry Pi, but currently only the official first version with 800x480
-resolution is supported.  Infix supplies all drivers required to utilize
-the hardware, but you need to add the actual graphical application in a
-container.
+**Raspberry Pi 3B:**

-There are some important considerations you need to know about when
-using Infix for graphical applications.  The container needs access to
-`/dev/dri/` to be able to access the graphics card, it also need access
-to `/run/udev` to be able to find the input devices.

+   - SSH to the DHCP-assigned IP address
+   - Default login: `admin` / `admin`
+
+> [!NOTE]
+> Raspberry Pi 3B and 4B boot with a factory configuration (`factory-config.cfg`)
+> that enables DHCP client on the Ethernet port. This means you can access
+> the device over the network without needing a serial console. Simply find
+> the assigned IP address and SSH in!
+>
+> **Compute Module 4 (CM4)** and some other variants do not have this factory
+> configuration, so you'll need to use a serial console for initial setup or
+> configure the carrier board accordingly.
+
+### First Boot Notes
+
+On first boot, Infix will:
+
+- Obtain an IP address via DHCP on the Ethernet port
+- Generate unique SSH host keys
+- Initialize the configuration system
+
+You can find the assigned IP address by:
+
+- Checking your DHCP server/router's client list
+- Using network scanning tools like `nmap` or `arp-scan`
+- Connecting via serial console and running `ip addr` (if needed)
+
+## Hardware-Specific Features
+
+### WiFi Configuration
+
+Both Pi 3B and Pi 4B include dual-band WiFi that can be configured as a
+client (station mode). See the [Infix WiFi documentation][9] for detailed
+configuration examples.
+
+To configure WiFi as a client, first store your WiFi password in the keystore:

 ```
-admin@example:/> configure
-admin@example:/config/> edit container doom
-admin@example:/config/container/doom/> set image docker://mattiaswal/alpine-doom:latest
-admin@example:/config/container/doom/> set privileged
-admin@example:/config/container/doom/> edit mount udev
-admin@example:/config/container/doom/mount/udev/> set type bind
-admin@example:/config/container/doom/mount/udev/> set target /run/udev/
-admin@example:/config/container/doom/mount/udev/> set source /run/udev/
-admin@example:/config/container/doom/mount/udev/> end

-admin@example:/config/container/doom/mount/xorg.conf/> end
-admin@example:/config/container/doom/> edit volume var
-admin@example:/config/container/doom/volume/var/> set target /var
-admin@example:/config/container/doom/volume/var/> leave
-admin@example:/>
+admin@infix:/> configure
+admin@infix:/config/> edit keystore symmetric-key mywifi
+admin@infix:/config/keystore/…/mywifi/> set key-format wifi-preshared-key-format
+admin@infix:/config/keystore/…/mywifi/> set cleartext-key YourWiFiPassword
+admin@infix:/config/keystore/…/mywifi/> leave
+```
+
+Then configure the WiFi interface using the keystore reference:
+
+```
+admin@infix:/> configure
+admin@infix:/config/> edit interface wifi0
+admin@infix:/config/interface/wifi0/> set ipv4 dhcp-client
+admin@infix:/config/interface/wifi0/> set wifi ssid YourNetworkName
+admin@infix:/config/interface/wifi0/> set wifi secret mywifi
+admin@infix:/config/interface/wifi0/> set wifi country-code US
+admin@infix:/config/interface/wifi0/> leave
 ```

 > [!NOTE]
-> The `xorg.conf` [content mount][2] is a nifty detail of Infix that
-> allows you to keep all the relevant configuration in a single file.
-> The deta is "simply" `base64` encoded, so you do not really need the
-> features of the Infix CLI, everything can be set up remotely [using
-> `curl`][3] if you like.
+> The WiFi password (8-63 characters) is stored securely in the keystore as
+> `mywifi` (or any name you choose), which is then referenced in the WiFi
+> configuration. The country-code must match your location for regulatory
+> compliance (e.g., US, SE, DE, JP).

-### Pre-built images
+### Touch Screen Support

-Pre-built SD card images are available here: [infix-rpi64-sdcard.img][sdcard]
+The [Raspberry Pi Touch Display v1][10] (800x480 resolution) is supported on
+the Pi 4B, including touch functionality. To use graphical applications with
+the touch screen, you need to run them in a container with proper device
+access.

+#### Requirements for Graphical Applications
+
+Containers need:
+- Access to `/dev/dri/` for graphics card access
+- Access to `/run/udev` for input device detection
+- Privileged mode or specific capabilities
+

+
+### Power Supply Requirements
+
+Proper power supply is critical for stable operation:
+
+- **Raspberry Pi 4B:** 5V/3A USB-C power supply (official recommended)
+- **Raspberry Pi 3B:** 5V/2.5A micro-USB power supply
+- **Compute Module 4:** Power requirements depend on carrier board
+
+Inadequate power can cause:
+- Random reboots or crashes
+- USB device failures
+- Network disconnections
+- Corrupted storage
+
+<img align="right" src="gpio-pinout.png" alt="GPIO Pinout" width=300 padding=10>
+
+### Serial Console Access (Optional)
+
+A serial console is useful for debugging but not required for Pi 3B/4B, since
+the factory configuration enables network access via DHCP. For CM4 and other
+variants without factory configuration, serial console access is required for
+initial setup.
+
+To connect via serial:
+
+1. Connect a USB-to-TTL serial adapter (3.3V) to GPIO pins:
+   - GND (black wire) → Pin 6 (Ground)
+   - TX → Pin 8 (GPIO 14, RXD)
+   - RX → Pin 10 (GPIO 15, TXD)
+   - **VCC (red wire) → Leave disconnected** (Pi has its own power supply)
+2. Use 115200 baud, 8 data bits, no parity, 1 stop bit (115200 8N1)
+3. Connect using `screen`, `minicom`, or similar terminal emulator
+
+The image shows the standard 40-pin GPIO header pinout. For serial console:
+- **Pin 6** (black) = Ground
+- **Pin 8** (orange) = TxD (UART) - connect to RX on your adapter
+- **Pin 10** (orange) = RxD (UART) - connect to TX on your adapter
+
+> [!WARNING]
+> Use only 3.3V serial adapters. 5V adapters will damage your Raspberry Pi!
+
+## Troubleshooting
+
+### Board won't boot
+
+- Verify the power supply meets requirements (see [Power Supply Requirements](#power-supply-requirements))
+- Check that the SD card is properly seated
+- Try re-flashing the SD card image
+- Look for the green LED activity indicator (should flash during boot)
+- Connect via serial console to see boot messages if needed
+
+### Can't find IP address
+
+- Ensure Ethernet cable is properly connected (look for link LED activity)
+- Verify your DHCP server is running and has available addresses
+- Check your router/DHCP server's client list for new devices
+- Use `nmap` or `arp-scan` to scan your network
+- Connect via serial console and run `ip addr` to see the assigned address
+
+### WiFi not working
+
+- Verify WiFi regulatory domain is set correctly
+- Check that SSID and password are correct
+- Ensure WiFi channel is supported in your region
+- Try connecting to a 2.4 GHz network first (better compatibility)
+
+### SD card corruption
+
+If the system becomes unresponsive or won't boot:
+
+- Always use proper shutdown procedures (don't just pull power)
+- Use a quality SD card (Class 10, A1, or better recommended)
+- Consider using a UPS or battery backup for critical deployments
+- Verify power supply meets requirements (see [Power Supply Requirements](#power-supply-requirements))
+
+### Container/Docker issues
+
+- Verify adequate RAM is available (check with `free -h`)
+- Ensure sufficient SD card space (check with `df -h`)
+- For Pi 3B, consider using lighter containers due to limited RAM
+
+## Additional Resources
+
+- [Infix Documentation][1]
+- [Flashing SD Card Guide][0]
+- [Infix Container Documentation][3]
+- [Scripting with RESTCONF][4]
+- [Release Downloads][8]
+- [Official Raspberry Pi Documentation][11]
+
+## Building Custom Images
+
+See the main Infix documentation for building from source. To build a custom
+Raspberry Pi image:
+
+```bash
+# Build the bootloader (only needed once or when bootloader changes)
+make O=x-boot rpi64_boot_defconfig
+make O=x-boot
+
+# Build main system
+make aarch64_defconfig
+make
+
+# Create SD card image
+./utils/mkimage.sh -od raspberrypi-rpi64
+```
+
+The resulting image will be in `output/images/infix-rpi64-sdcard.img`.
+
+### Customizing the Build
+
+You can customize the build by:
+- Modifying `board/aarch64/raspberrypi-rpi64/config.txt` for boot configuration
+- Adding packages to the Buildroot configuration
+- Customizing the device tree in `board/aarch64/raspberrypi-rpi64/dts/`
+
+## Performance Notes
+
+### Raspberry Pi 4B vs 3B
+
+The Pi 4B offers significant improvements over the 3B:
+- 3x faster processor
+- Up to 8x more RAM
+- Gigabit Ethernet (vs 100 Mbps)
+- USB 3.0 for faster storage and peripherals
+- Better thermal performance
+
+For network-intensive applications, the Pi 4B is strongly recommended.
+
+### Raspberry Pi as a Router
+
+While capable of basic routing tasks, be aware of limitations:
+- Single Ethernet port (consider USB Ethernet adapters for multi-port setups)
+- CPU-based packet processing (no hardware offload)
+- Best suited for home/lab use rather than high-throughput production
+
+For applications requiring multiple ports or high performance, consider
+dedicated networking hardware like the [Banana Pi R3][12].
