Hardware-in-loop

Hardware in loop allows remote code uploading onto STM32 boards without physical presence near the boards.

Mission

This project uses a Raspberry Pi as a hub to remotely pull code from Git Hub and upload code to the STM32 board. The aim is to facilitate the rapid development of code.

Requirements

1. An STM32 board
2. A Raspberry Pi
3. Github Actions Runner This can be set up by going to the settings -> actions -> runner and setting up a Linux runner. Follow all the commands '''except the last command''' which executes the run.sh shell script.
4. Libraries
   • Setting up printf and scanf using this website
   • Run this sudo command to ensure your system's package list is up to date:

   sudo apt update
   sudo apt-get update
   

   • Install stlink and its dependencies:

   sudo apt-get install stlink-tools
   

   • Install libtool and its dependencies:

   sudo apt install libtool
   

   • Install the ARM GCC toolchain:

   sudo apt install gcc-arm-none-eabi
   

   • Installing OpenOCD using the code below

       git clone git://git.code.sf.net/p/openocd/code
       cd code/
       ./bootstrap
       ./configure
       make
       sudo make install
       cd ..
       rm -rf code/
       sudo nano /etc/udev/rules.d/stlink.rules
   

   Now paste this at the end of the file

   KERNEL=="tty[A-Z]*[0-9]", MODE="0666"
   SUBSYSTEM=="usb", ATTRS{idVendor}=="0483", MODE="0666"
   

Execution

The worklfow on the yaml file starts when a push is made to main. Add the file paths to the YAML file. These file paths are labelled in the env section of the YAML file. To execute this project to the location of the self hosted runner loaction and execute ./run/sh.

Precautions

In case the runner is deleted, please go ahead and reinstall the runner at the same location (which by default shall be actions-runner). To do this, skip the first command (*mkdir.....*) . If you get an error while configuring, execute

ls -a
rm -f .runnner
rm -f config.sh
