             # rpi23-gen-image
             ## Introduction
-            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for Raspberry Pi 2 (RPi2) and Raspberry Pi 3 (RPi3) computers. The script at this time supports the bootstrapping of the Debian (armhf) releases `stretch` and `buster`. Raspberry Pi 3 images are generated for 32-bit mode only. Raspberry Pi 3 64-bit images can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.14.y```).
+            `rpi23-gen-image.sh` is an advanced Debian Linux bootstrapping shell script for generating Debian OS images for all Raspberry Pi computers. The script at this time supports the bootstrapping of the Debian (armhf/armel) releases `stretch` and `buster`. Raspberry Pi 0/1/2/3 images are generated for 32-bit mode only. Raspberry Pi 3 supports 64-bit images that can be generated using custom configuration parameters (```templates/rpi3-stretch-arm64-4.14.y```).
             ## Build dependencies
             The following list of Debian packages must be installed on the build system because they are essentially required for the bootstrapping process. The script will check if all required packages are installed and missing packages will be installed automatically if confirmed by the user.
               ```debootstrap debian-archive-keyring qemu-user-static binfmt-support dosfstools rsync bmap-tools whois git bc psmisc dbus sudo```
-            It is recommended to configure the `rpi23-gen-image.sh` script to build and install the latest Raspberry Pi Linux kernel. For the RPi3 this is mandatory. Kernel compilation and linking will be performed on the build system using an ARM (armhf) cross-compiler toolchain.

-            The script has been tested using the default `crossbuild-essential-armhf` toolchain meta package on Debian Linux `stretch` build systems. Please check the [Debian CrossToolchains Wiki](https://wiki.debian.org/CrossToolchains) for further information.

             ## Command-line parameters
             The script accepts certain command-line parameters to enable or disable specific OS features, services and configuration settings. These parameters are passed to the `rpi23-gen-image.sh` script via (simple) shell-variables. Unlike environment shell-variables (simple) shell-variables are defined at the beginning of the command-line call of the `rpi23-gen-image.sh` script.
             Set Proxy server address. Using a local Proxy-Cache like `apt-cacher-ng` will speed-up the bootstrapping process because all required Debian packages will only be downloaded from the Debian mirror site once. If `apt-cacher-ng` is running on default `http://127.0.0.1:3142` it is autodetected and you don't need to set this.
             ##### `APT_INCLUDES`=""

-            A comma separated list of additional packages to be installed by apt after bootstrapping and after APT sources are set up.  This is useful for packages with pre-depends, which debootstrap do not handle well.

             #### General system settings:
             ##### `SET_ARCH`=32
-            Set Architecture to default 32bit. If you want to to compile 64bit (RPI3 or RPI3+) set it to `64`. This option will set every needed crosscompiler or boeard specific option for a successful build.

-            `3P` = Used for Pi 3 model B+
+            - `3P` = Raspberry Pi 3 model B+
-            `BUILD_KERNEL`=true will automatically be set if the Raspberry Pi model `3` or `3P` is used.

             #### Networking settings (DHCP):
-            This parameter is used to set up networking auto configuration in `/etc/systemd/network/eth.network`. The default location of network configuration files in the Debian `stretch` release was changed to `/lib/systemd/network`.`
+            This parameter is used to set up networking auto-configuration in `/etc/systemd/network/eth.network`. The default location of network configuration files in the Debian `stretch` release was changed to `/lib/systemd/network`.`
             ##### `ENABLE_DHCP`=true
             Set the system to use DHCP. This requires an DHCP server.
             Set the IP address for the second DNS server.
             ##### `NET_DNS_DOMAINS`=""
-            Set the default DNS search domains to use for non fully qualified host names.
+            Set the default DNS search domains to use for non fully qualified hostnames.
             ##### `NET_NTP_1`=""
             Set the IP address for the first NTP server.
             #### Basic system features:
             ##### `ENABLE_CONSOLE`=true
-            Enable serial console interface. Recommended if no monitor or keyboard is connected to the RPi2/3. In case of problems fe. if the network (auto) configuration failed - the serial console can be used to access the system.
+            Enable serial console interface. Recommended if no monitor or keyboard is connected to the RPi2/3. In case of problems fe. if the network (auto) configuration failed - the serial console can be used to access the system. On RPI `0` `3` `3P` the CPU speed is locked at lowest speed.
+            ##### `ENABLE_PRINTK`=false
+            Enables printing kernel messages to konsole. printk is `3 4 1 3` as in raspbian.
+            ##### `ENABLE_BLUETOOTH`=false
+            Enable onboard Bluetooth interface on the RPi0/3/3P. See: [Configuring the GPIO serial port on Raspbian jessie and stretch](https://spellfoundry.com/2016/05/29/configuring-gpio-serial-port-raspbian-jessie-including-pi-3/).
+            ##### `ENABLE_MINIUART_OVERLAY`=false
+            Enable Bluetooth to use this. Adds overlay to swap UART0 with UART1. Enabling (slower) Bluetooth and full speed serial console. - RPI `0` `3` `3P` have a fast `hardware UART0` (ttyAMA0) and a `mini UART1` (ttyS0)! RPI `1` `1P` `2` only have a `hardware UART0`. `UART0` is considered better, because is faster and more stable than `mini UART1`. By default the Bluetooth modem is mapped to the `hardware UART0` and `mini UART` is used for console. The `mini UART` is a problem for the serial console, because its baudrate depends on the CPU frequency, which is changing on runtime. Resulting in a volatile baudrate and thus in an unusable serial console.
+            ##### `ENABLE_TURBO`=false
+            Enable Turbo mode. This setting locks cpu at the highest frequency. As setting ENABLE_CONSOLE=true locks RPI to lowest CPU speed, this is can be used additionally to lock cpu hat max speed. Need a good power supply and probably cooling for the Raspberry PI.
             ##### `ENABLE_I2C`=false

             ##### `ENABLE_SPI`=false
-            Enable SPI interface on the RPi2/3. Please check the [RPi2/3 pinout diagrams](https://elinux.org/RPi_Low-level_peripherals) to connect the right GPIO pins.

             ##### `ENABLE_IPV6`=true
             Enable IPv6 support. The network interface configuration is managed via systemd-networkd.
             Download and install the [closed-source firmware binary blob](https://github.com/RPi-Distro/firmware-nonfree/raw/master/brcm) that is required to run the internal wireless interface of the Raspberry Pi model `3`. This parameter is ignored if the specified `RPI_MODEL` is not `3`.
             ##### `ENABLE_RSYSLOG`=true
-            If set to false, disable and uninstall rsyslog (so logs will be available only
+            If set to false, disable and uninstall rsyslog (so logs will be available only in journal files)

+            Enable Hardware Random Number Generator. Strong random numbers are important for most network-based communications that use encryption. It's recommended to be enabled.
             ##### `ENABLE_MINGPU`=false
             Minimize the amount of shared memory reserved for the GPU. It doesn't seem to be possible to fully disable the GPU.
             Install Xorg open-source X Window System.
             ##### `ENABLE_WM`=""
-            Install a user defined window manager for the X Window System. To make sure all X related package dependencies are getting installed `ENABLE_XORG` will automatically get enabled if `ENABLE_WM` is used.

-            After the image file was successfully created by the `rpi23-gen-image.sh` script it can be copied to the microSD card that will be used by the RPi2/3 computer. This can be performed by using the tools `bmaptool` or `dd`. Using `bmaptool` will probably speed-up the copy process because `bmaptool` copies more wisely than `dd`.
