1-Build environment

Linux

Windows

Please make sure if you modify code, files, etc. that the line endings are UNIX conform (LF and not CRLF).

Using Linux subsystem under Windows 10 64-bit

notes: Script and instructions contributed by 3d-gussner. Use at your own risk. Script downloads Arduino executables outside of Prusa control. Report problems there..

• follow the Microsoft guide
• Tested versions are at this moment
  • Ubuntu other may different
  • After the installation and reboot please open your Ubuntu bash and do following steps
  • run command apt-get update
  • run command apt-get upgrade to update your OS.

Some Tips for Ubuntu

• Linux is case sensetive so please don't forget to use capital letters where needed, like changing to a directory
• To change the path to your Prusa-Firmware location you downloaded and unzipped
  • Example: You files are under C:\Users\<your-username>\Downloads\Arduino_Boards
  • use under Ubuntu the following command cd /mnt/c/Users/<your-username>/Downloads/Arduino_Boards to change to the right folder
• Unix and windows have different line endings (LF vs CRLF), try dos2unix to convert
  • This should fix the "$'\r': command not found" error
  • to install run apt-get install dos2unix

Modify Arduino_Boards with Ubuntu Linux subsystem installed

• open Ubuntu bash
• change to your source code folder (case sensitive)
• Read How-to-modify below
• run ./Prepare-new-version.sh
• Read How-to-modify part package_prusa3d_index.json below

Using Git-bash under Windows 10 64-bit

notes: Script and instructions contributed by 3d-gussner. Use at your own risk. Script downloads Arduino executables outside of Prusa control. Report problems there. Multi language build is supported.

• Download and install the 64bit Git version
• Also follow these instructions

Compile Prusa-firmware with Git-bash installed

• open Git-bash
• Read How-to-modify below
• change to your source code folder
• run bash Prepare-new-version.sh
• Read How-to-modify package_prusa3d_index.json below

Naming convention for version:

• <major:#1.minor:#2.maintenance:#2"-devel status:0-4-devel build:#6" where -devel status and devel build are optional
  • #1 = numbers 0-9
  • #2 = numbers 0-99
  • 0-4= only numbers between 0 and 4. 0=devel, 1=alpha, 2=beta, 3=pre-release, 4=release candidate
  • #6 = numbers 0-999999

Few examples:

• 1.0.0-0-235 Is a version in development and devel build 235.
• 1.0.0 Is the frist stable version
• 1.0.1 Is a stable version that was maintaind...like adding a bootloader or changing tools to existing boards
• 1.1.0-3 Is a pre-release version including new boards
• 1.1.0 Is the first stable version including new boards

After modifying the source code please follow these steps:

• add the new version (following the naming conention) in the first line of prusa3dboards.version

• run Prepare-new-version.sh to generate prusa3dboards-<version>tar.bz2 and to show sha256checksum and size needed in the package_prusa3d_index.json

• open package_prusa3d_index.jsonin your prefered editor (like notepad++)

• Copy and paste this section twice

• Modify the top one with new values

  • change "version": "1.0.2", `"version": "",
  • change in "url": and "archiveFileName": the "ArchiveFileName" parts you got from Prepare-new-version.sh
  • if you have your own github for of this repository and you made a new worktree/branch to test your code you should not forget to modify the "url": to your branch
  • change in "checksum": the "SHA256 checksum" you got from Prepare-new-version.sh
  • change in "size": the "Size" you got from Prepare-new-version.sh

• double check the syntax/format of the JSON file. In Notepad++ makes it is quite easy by using the [+] and [-] to see if your changes are correct.

When you have an own github and work localy use git status to verify your status.

• You may need to use git add IDE_Board_Manager/prusa3dboards-<version>.tar.bz2
• You need to commit your changes with git commit -a. Please try to document your changes as detailed as possible.
