BeagleBone Serial Terminal Server

The BeagleBones have 4 capable UARTs and the goal of this project is to provide the end user an image to configure, access and control the UART devices using a user friendly interface or SSH directly into the BBB to take control of the UART device.

About your project

Project name: BeagleBone-based Serial Terminal Server

Description

There are two key points to approach this project. First, SSH into the BBB to control the UART devices. Second, create a deployable image to easily configure the UART devices. To enable the BBB to take control of UART devices and to issue commands to it using a serial connection:

  1. Use of simple system management daemons such as Systemd can be used which is the first daemon process to execute on BBB.
  2. Obtain a full list of services running (systemctl list-units -t service |grep tty)
  3. Get the status of the current serial service (systemctl status <running service>)
  4. Replace the serial service with a custom application service by disabling the current serial service (sudo systemctl stop <service>) and then disable it from boot
  5. Deploy your own design serial service.

Timeline

To be written.

Experience and approach

  1. Prior knowledge of embedded systems, soldering, device drivers, C and have worked with BBB, RaspberryPi and ESPs.
  2. I run my open source website to teach basic electronics and device drivers at : http://saumitra.co/
  3. Before the start of the project, I have well equipped myself with the necessary tools and skills to start off.

Contingency

  1. Talk to people on IRC and beagleboard community
  2. For serial and UART configuration I will follow : http://www.iitk.ac.in/LDP/HOWTO/Serial-HOWTO-16.html for troubleshooting
  3. Follow the online resources : https://en.wikibooks.org/wiki/Serial_Programming
  4. Google it
  5. Read documentation page
