Hello,

I looked at your project briefly and as Martin mentioned you haven't set the external loader for the F746-DISCO board in your CubeIDE project.

Here is the location where you need to modify it :

0693W000005A8dGQAS.pngIf this external loader is not set correctly I'm starting to wonder if you used the F746-DISCO Application Template available in the Designer. If you haven't, please in the future if you try to run some code on a board that we support, start with the corresponding Application Template to avoid unnecessary issues.

For the step to upgrade to a newer version, please have a look to this article in our documentation website : https://support.touchgfx.com/docs/miscellaneous/updating-to-a-new-touchgfx-version

What are you expecting the application to look like? Is the External Flashloader configured properly for your project?
