Add Mono And .NET Runtime

Adding .NET Framework v. 4.8 with Mono Runtime

Running Bee Mobile iDesk components and controls on your efus MX8MP board requires .NET Framework v. 4.8. On Embedded Linux, .NET Framework v. 4.8 is implemented by Mono Runtime.

1. In your Fedora VM, Start Visual Studio Code.
2. File → Open Folder → open /home/developer/fsimx8mp-Y2025.12/build/yocto-fus folder.
3. Terminal → New Terminal folder.
4. Verify in terminal, that you are located in /home/developer/fsimx8mp-Y2025.12/build/yocto-fus/sources folder.
   Copy

   pwd

   If not, then cd into it.

5. Git clone meta-mono layer.
   Copy

   git clone https://github.com/DynamicDevices/meta-mono.git -b scarthgap
   cd meta-mono

We are going to create a new recipe that will allow us to build OS which includes Mono runtime. We will call the recipe fus-image-mono.

6. In Visual Studio Code’s file browser, browse to folder, where OS image recipes are defined, that is into: meta-fus/recipes-config/images.
7. Create a new file fus-image-mono.bb in the folder. Feel free to utilize Visual Studio Code’s file explorer and code editor to do this. Depending no your taste, it is probably more simple that way, as opposed to typing commands into terminal. If you prefer terminal way of doing things, you can do that too.
8. Put this content into it:
   Copy

   	DESCRIPTION = "F&S Mono image"
   LICENSE = "MIT"
    
   require recipes-config/images/fus-image-std.bb
    
   inherit features_check
   IMAGE_INSTALL += "mono tzdata libgdiplus"
   DEFAULT_TEST_SUITES_pn-${PN} = "mono ssh ping"

   Save the file.

9. Now open a different folder with Visual Studio Code: File → Open Folder → open /home/developer/fsimx6-Y2024.04.1/build/yocto-fus/build-fsimx6-fus-imx-xwayland/conf folder.
10. In Visual Studio Code, open bblayers.conf file.
11. Add this line to the end of it:
    Copy

    BBLAYERS += "${BSPDIR}/sources/meta-mono"

12. Terminal → New Terminal folder.
13. Browse into /home/developer/fsimx6-Y2024.04.1/build/yocto-fus folder again.
    Copy

    cd /home/developer/fsimx6-Y2024.04.1/build/yocto-fus

14. Set environment variables.
    Copy

    DISTRO=fus-imx-xwayland MACHINE=fsimx8mp source setup-environment build-fsimx8mp-fus-imx-xwayland

15. Start OS build process.
    Copy

    bitbake fus-image-mono
