  • USB programmer/debugger SEGGER J-Link Compact Plus + Cortex-M Adapter

    • Can be provided by HARDWARIO

  • USB power source Power Profiler Kit 2 (PPK2)

    • Can be provided by HARDWARIO

  • One of these operating systems:

    caution

    Despite all the operating systems being supported and working the same way, we have experienced extremely long build times on the Windows platform. For serious development, we recommend getting a PC with Ubuntu, or macOS. Alternatively, you will get better results in a virtualized environment (e.g. VirtualBox).

    • Ubuntu 20.04 / 22.04
    • macOS 11 / 12
    • Windows 10 / Windows 11

GitHub Access​

We share the latest SDK on GitHub in chester-sdk repository. Please create a GitHub account and add follow next chapter on how to add an SSH key.

Generate SSH Key​

If you have not generated your SSH public/private key yet, you can do so using this command:

ssh-keygen

This will help you to generate the keys in your home folder. You should have files id_rsa (private key) and id_rsa.pub (public key) in the folder .ssh of your home directory.

danger

You must make sure the private key will not get to anybody else. Verify permissions on your key file.

Upload SSH Key​

Your public SSH key must be uploaded to your GitHub account. Log in to GitHub and open Settings (from the top right corner). Next, click on SSH Keys and PGP keys, click New SSH key, insert the content of your public key to the text area, give it a name, and click on Add SSH key.

You can test your connection with this command:

ssh -T git@github.com

It should output something like this:

Hi <YOUR_NICK_NAME>! You've successfully authenticated, but GitHub does not provide shell access.
