Proposal for Beagle Config


  • Pre-application phase


  • Completed all the general requirements
  • Completed "Hello Wolrd" of cross-compilation mentioned in the requirements list.
  • Sent a PR to the mentioned upstream #145

About You

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 a network i.e. editing iptables and enabling forwarding on the host pc is an uphill task without a script provided. However running scripts could be dangerous.
  • Enabling the PRU and loading the firmware is much daunting and unless anybody goes through their usage Documentations it will be difficult.
  • 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, a host-side application to enable ICS
  • Not only does it makes beagle devices more friendly but provides an edge to beagle devices over other similar platforms.
  • Also while configuring sometimes if the script has hard-coded values it makes it 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 as well as a host-side application for ICS

Implementation Details

  • Beagle-Config consists of a host-side application developed with cross-platform framework Qt .
  • Beagle-Config on user (board) side which will use bash, C/C++ as back end for low level access to linux's userspace api and FTXUI for frontend.
  • All the configuration options are stored in user's home directory inside ~/beagleconf.json
  • A restore to defaults option


  • Internet Connection Sharing Enabling nn linux as well as windows
  • console for SSH within the application

User (Board)

System Options

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 (/var/lib/cloud9/common/Makefile TARGET=gpio.prux start) if they want to test their PRU code in c or in simppru (Checks and asks if they want to install) . Example -

               PRU Conf
                       PRU 1 Enable Disable
                       PRU 2 Enable Disable
  • GPIO configuration

Enabling a GPIO pin for input/output using config-pin Example -

                GPIO 18 -
                       Enable Disable Set Value

For beaglebone blue motor driver, servo driver configurations

  • Internet Sharing and Client Configurations

Enables users to share their host internet with a click Example -

                   Host A
                       Enable Internet
                               Set IP gateway
                       Return to Defaults
               Host Name           BBB
               Country Code       <Select Menu>
  • eMMC stats

Enables users to extend the sd card partition size if available Example -

              eMMC Storage        Total 52 %
                   Free            --------
                   Extend          --------

  • Freeze Packages

apt-mark hold <package> and make a note of it in JSON

  • Wireless Configurations

For wireless-enabled devices like beaglebone black wireless configuring Access Point names, mDNS configurations, etc

  • Sensor Stats and Configurations

If beagle bone has onboard sensors then enabling them, viewing stats For ex. on Beaglebone Blue 9-axis IMU, barometer, thermometer, and a balancing LiPo charger are present

  • Password

Configure passwords along with the 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.

  • Firmware Update

Firmware - apt update and upgrade to update your system,

Display Options

  • Resolution

Enable configuration of HDMI/DVI if the board supports it

Interfacing Options

  • Cape Configurations

Performs apt install bb-cape-overlays If a beagle board and its associated cape need a configuration, this can be configured here easily.

  • SSH

Configure ssh, enable/disable, and setup password

  • Provide an easy interface to manage uboot overlays

U-Boot /boot/uEnv.txt configuration in /boot/uEnv.txt:

               To Disable eMMC:
               To Disable HDMI VIDEO & AUDIO:
  • Overlay File System

Enable or disable a read-only file system

  • Timezone

Select your local time zone, starting with the region, e.g. India, then selecting a city, e.g. Mumbai. Type a letter to skip down the list to that point in the alphabet.

Experience and approach

  • Previously I have worked with Qt and Boost.ASIO . PID-Tuning-GUI is an application that sends data to ESP32 microcontroller which supports WiFi connectivity. Handled Application threads and Plotting of data as well as sending user input to the microcontroller.
  • kernel learn is a repository I had created for kernel learning purpose in which I had learned several Kernel development Basics.
  • I have played with Pocketbeagle for a month and learned a lot about u-boot, device trees, and Loadable Kernel Modules.
  • This gives me the best of both the worlds embedded as well as a bit in frontend (Qt).


  • There is good documentation of FXTUI and Qt
  • Plenty of examples to get me through if I am stuck.
  • Past experience regarding Qt and DOM manipulation combined with experience in embedded and loadable kernel module development will pay off in this duration.


  • Having a seamless one-click experience to configure is enjoyed by any user, be it production or a robotics team.
  • Provides a configuration file to the users. Remembers defaults and helps in accidental modification to low-level configurations.



  • For hello_world of cross-compilation, sent a PR to the mentioned upstream #145

Future Work

  • Theme options
  • Flashing functionality can be added instead of making the user download a third party application like etcher
  • An IDE within the beagle-config host
