Considering the fact that a large number of our users, especially students, want to test and run applications on a Raspberry Pi, but are not able to purchase such devices, our team came up with a solution that could meet their needs. In the new realease of Wyliodrin STUDIO, we included a Raspberry Pi Emulator, a feature that will allow the mirroring of the performances of a Raspberry Pi Zero or 1.
The first step into running an emulator on your computer within Wyliodrin Studio is to install the right version of the QEMU machine emulator for your computer, from qemu.org. If your PC is running on Windows, you will have to add qemu in the PATH variable. In order to accomplish that, you will have to right click on This PC, select Properties, open the Environment Variables option, then edit the PATH variable. Here, you will have to add the absolute path to the folder where you chose to install qemu. The last step is to save the changes.
You can find the option to configure and run emulators in the Menu. In the first tab of the prompt that pops up, you can find a list with all the supported types of emulators, for the moment the only one being the Raspberry Pi.
If you don’t have any kernel image, you will have the option to download one previously configured by us. By clicking on the “Download image” button, a zip archive will be downloaded and unzipped in a special folder created on your computer. Once the download and decompression processes will be done, 2, new options will be available for the emulator.
As you can see in the picture shown above, you can either click on the Delete image button, that will permanently remove the kernel image from your computer, or on the Create new emulator button.
This last option will pop up a prompt where you will be asked to input the name of your emulator. You will have to enter a valid name, having at least one character, that has not been already used for another emulator. This action will start the boot process for your emulator, by copying the kernel image into a folder specifically created for the new emulator. In a few minutes, the Raspberry Pi emulator will show up on your computer.
By switching to the second tab of the Emulator prompt, you will see a list of all the available emulators that exist on your computer.
Here, for each available emulator, you will have 3 options:
Stop Emulator - this button will kill the session for a chosen emulator, but your settings will be saved within the special folder.
Restart Emulator - this button will be visible on each restart of Wyliodrin STUDIO or after each stop of an emulator. It will allow you to restart an emulator and to reload your changes and settings.
Delete Emulator - this button will ask you if you really want to delete an emulator. By answering yes, the selected emulator will be permanently removed from your computer and you will lose all the saved data.
Once the emulator completely loaded, you will be asked to input the default username and password, which are: pi / raspberry and you will have to start the ssh session by typing: sudo systemctl ssh start.
After that, you will be able to find your emulator in the Connection Menu and to connect to it.
