Computer Systems Experiments 3 | Configure Experiment Environment

First, let’s clone my ComputerSysE repo from GitHub to your home directory,

$ cd ~
$ git clone https://github.com/Sadamingh/ComputerSysE.git

Then, get the path of the environment folder,

$ cd ComputerSysE/environment
$ pwd

If you follow my instruction and successfully cloned my repo, the path should be,

~/ComputerSysE/environment

Assume that you are using macOS and bash, let’s edit the .bashrc file at the home directory (if it doesn't exist, create a new .bashrc file),

$ vi .bashrc

we add the following two statements to into this file,

export ENV=~/ComputerSysE/environment
export PATH=$PATH:$ENV/bin

Then we restart the shell,

$ source .bashrc

If all the things are right, you can use the pinout command now to get a diagram of the pins (it is located at ~/ComputerSysE/environment/bin) and we can find it by.

$ cat ~/ComputerSysE/environment/bin/pinout

Also, we have to make sure that we have an essential file named rpi-install.py and we will use it to transfer files to the Raspberry Pi. We can check its version by,

$ rpi-install.py -h

The output should be,

usage: rpi-install.py [-h] [-d device] [-v]  [-p | -s] [file]

This script sends a binary file to the Raspberry Pi bootloader. Version 1.1
