Confirm that you installed the QEMU interface add-on. Use the Add-On Manager to view and manage installed add-ons. If the QEMU interface add-on is not installed, use the Add-On Explorer to find and install it. For details, see Get and Manage Add-Ons.

At the MATLAB^® command line, confirm that you can create a connection to the QEMU by using this command:

qemu

If errors are returned, continue to the next troubleshooting step.

Check that the third-party software tools provided by the Embedded Coder^® Support Package for ARM^® Cortex^®-A Processors are correctly installed. At the MATLAB command line, run this command to identify the root folder of the support package:

matlabshared.supportpkg.getSupportPackageRoot

Navigate to that root folder, and confirm that the armcortexa folder is present. If the folder is not present, use the Add-Ons Manager to install the support package. For details on this installation, see Install Support for ARM Cortex-A Processors.
