About Your Project
- Project name: Beagle Config
- As we all know , nearly all of the user operations in Linux can be done using shell commands , scripts and Linux Userspace Api for advanced users. But all that being said for an average user and sometimes in production these steps can be repetitive and time consuming. For example- Simply sharing network i.e. editing iptables and enabling packet forwarding with Pocketbeagle is an uphill task without a script provided. However running scripts could be dangerous. Even adding a USB gadget without rcn-ee's boot script is definitely difficult.
- Enabling the PRU and loading the firmware is much daunting and unless anybody goes through their usage Documentations it will be difficult.
- Not only does it makes beagle devices more friendly but provides an edge to beagleboard over other similar platforms.
- Hence I propose *beagle-config* which is a terminal based UI application that brings down the steep curve and enables anybody to config their beagle device as they wish.
- Also while configuring sometimes if the script has hard coded values it makes difficult for the user to go back to default configurations. With beagle-config that won't be a problem anymore
- Goal : Beagle-Config aims to provide the functionality to make the most common low level configuration changes in beagle devices easily and providing a terminal UI to do the same.
- Here are few details of the beagle-config which will use bash, C/C++ as back end for low level access to linux's userspace api and FTXUI for frontend.
The system options sub menu allows you to make configuration changes to various parts of the boot, login and networking process, along with some other system level changes.
- PRU enable/disable
This will enable hobbyists to enable / disable their PRUs if they want to test their PRU code in c or in simppru . Example -
PRU Conf PRU 1 Enable Disable PRU 2 Enable Disable
- GPIO configuration
Enabling a GPIO pin for input/output Example -
GPIO 18 - Enable Disable Set Value
- Internet Sharing and Client Configurations
Enables users to share their host internet within a click Example -
Host Host A Enable Internet Advanced Set IP gateway Return to Defaults Host Name BBB Edit
- Wireless Configurations
For wireless enabled devices like beaglebone black wireless configuring Access Point names , mDNS configurations, etc
- Sensor Configurations
If beagle bone has onboard sensors then enabling them , viewing stats like charging status, battery status , power consumption, etc.
- Audio Configurations
If beagle supports audio on board Specify Audio Output
Configure passwords along with addition of users, groups
- Boot / Auto login
We can configure whether to boot in desktop mode or using just console enabled. Add option to login automatically.
- User LED
Configure the USR Leds on the board. Their frequency and events.
- Display Options
Enable configuration of HDMI/DVI if the board supports
- Interfacing Options
- Overlay File System
- Remote GPIO
- Network Proxy Settings
- Expand Filesystem
- Cape Specific Configurations
- USB Gadget configurations
- Device Tree Add-ons/Overlays
- Provide an easy interface to add overlays to device trees
For example -
Select Node - Select Property Edit Property Add Node - Add Alias Add Address Add Property Add register address
Allows setting of the wireless LAN SSID and passphrase.
Specifiy the audio output destination.
The default user on Raspberry Pi OS is pi with the password raspberry. You can change that here. Read about other users.
Set the visible name for this Pi on a network.
From this submenu you can select whether to boot to console or desktop and whether you need to log in or not. If you select automatic login, you will be logged in as the pi user.
Use this option to wait for a network connection before letting boot proceed.
Enable or disable the splash screen displayed at boot time
If the model of Pi permits it, you can change the behaviour of the power LED using this option.
Define the default HDMI/DVI video resolution to use when the system boots without a TV or monitor being connected. This can have an effect on RealVNC if the VNC option is enabled.
Underscan Old TV sets had a significant variation in the size of the picture they produced; some had cabinets that overlapped the screen. TV pictures were therefore given a black border so that none of the picture was lost; this is called overscan. Modern TVs and monitors don't need the border, and the signal doesn't allow for it. If the initial text shown on the screen disappears off the edge, you need to enable overscan to bring the border back.
Any changes will take effect after a reboot. You can have greater control over the settings by editing config.txt.
On some displays, particularly monitors, disabling overscan will make the picture fill the whole screen and correct the resolution. For other displays, it may be necessary to leave overscan enabled and adjust its values.
Pixel Doubling Enable/disable 2x2 pixel mapping.
Composite Video On the Raspberry Pi4, enable composite video. On models prior to the Raspberry Pi4, composite video is enabled by default so this option is not displayed.
Screen Blanking Enable or disable screen blanking.
Interfacing Options In this submenu there are the following options to enable/disable: Camera, SSH, VNC, SPI, I2C, Serial, 1-wire, and Remote GPIO.
Enable/disable the CSI camera interface.
Enable/disable remote command line access to your Pi using SSH.
SSH allows you to remotely access the command line of the Raspberry Pi from another computer. SSH is disabled by default. Read more about using SSH on the SSH documentation page. If connecting your Pi directly to a public network, you should not enable SSH unless you have set up secure passwords for all users.
VNC Enable/disable the RealVNC virtual network computing server.
Enable/disable SPI interfaces and automatic loading of the SPI kernel module, needed for products such as PiFace.
Enable/disable I2C interfaces and automatic loading of the I2C kernel module.
Serial Enable/disable shell and kernel messages on the serial connection.
1-wire Enable/disable the Dallas 1-wire interface. This is usually used for DS18B20 temperature sensors.
Enable or disable remote access to the GPIO pins.
Overclock On some models it is possible to overclock your Raspberry Pi's CPU using this tool. The overclocking you can achieve will vary; overclocking too high may result in instability. Selecting this option shows the following warning:
Be aware that overclocking may reduce the lifetime of your Raspberry Pi. If overclocking at a certain level causes system instability, try a more modest overclock. Hold down the Shift key during boot to temporarily disable overclocking.
GPU Memory Change the amount of memory made available to the GPU.
Enable or disable a read-only filesystem
Fan Set the behaviour of a GPIO connected fan
Localisation Options The localisation submenu gives you these options to choose from: keyboard layout, time zone, locale, and wireless LAN country code.
Locale Select a locale, for example en_GB.UTF-8 UTF-8.
Time Zone Select your local time zone, starting with the region, e.g. Europe, then selecting a city, e.g. London. Type a letter to skip down the list to that point in the alphabet.
Keyboard This option opens another menu which allows you to select your keyboard layout. It will take a long time to display while it reads all the keyboard types. Changes usually take effect immediately, but may require a reboot.
WLAN Country This option sets the country code for your wireless network.
If you have installed Raspberry Pi OS using NOOBS, the filesystem will have been expanded automatically. There may be a rare occasion where this is not the case, e.g. if you have copied a smaller SD card onto a larger one. In this case, you should use this option to expand your installation to fill the whole SD card, giving you more space to use for files. You will need to reboot the Raspberry Pi to make this available. Note that there is no confirmation: selecting the option begins the partition expansion immediately.
GL Driver Enable/disable the experimental GL desktop graphics drivers.
GL (Full KMS) Enable/disable the experimental OpenGL Full KMS (kernel mode setting) desktop graphics driver.
GL (Fake KMS) Enable/disable the experimental OpenGL Fake KMS desktop graphics driver.
Legacy Enable/disable the original legacy non-GL VideoCore desktop graphics driver.
Compositor Enable/Display the xcompmgr composition manager
Network Interface Names Enable or disable predictable network interface names.
Configure the network's proxy settings.
On the Raspberry Pi4, you can specify whether to boot from USB or network if the SD card isn't inserted. See this page for more information.
Bootloader Version On the Raspberry Pi4, you can tell the system to use the very latest boot ROM software, or default to the factory default if the latest version causes problems.
Update Update this tool to the latest version.
