TouchGFX 4.17 is now live with dual core support and along a new release of the TouchGFX Board Setup (new name for "Application template") for the STM32H747-disco board based on STM32CubeMX and with a STM32CubeIDE project.
We currently cannot give you an answer yet because this is something related to CubeMX. So as soon as CubeMX supports the STM32H747, we will create the corresponding Application Template that will support CubeIDE.
This is something that got requested quite a few times so we'll try to push it so that the release comes as soon as possible.
