Why TouchGfx Designer can't connect to the target?

[Chriss]

Hi,

in the TouchGFX Designer I created a new Application with the Aplication Template STM32L4R9I Discovery. I used the UI Template TouchGFXWatch specified for the Discovery board.

When I now click on "RunTarget" I'll get an Error that the target is not reachable. The ST-Link from the Discovery board is present.

What is wrong? Have I forgotten something?

Regards

Christian

Hi @Community member​,

Can you connect to the board just using ST-Link? Are you alrady connected to the board using ST-Link GUI? (This would prevent any others from connecting - Like the designer which calls ST-Link CLI). Or maybe you have multiple boards connected?

Thanks!

Best regards,

Martin

Hi Martin,

with the ST-Link Utility I can connect to the target. So I disconnected the ST-Link Utility and closed the App. Then I started the TouchGFX Designer, opened my project and try to run target, without success. The LED for the ST-Link flashes one short time green and after that an error message came up... "please make sure you have the right target connected." !?

This also happens when I use the UI Template TouchGFXWatch!?

Best regards

Be sure that the tools are updated to the latest release else you may face these issues.

What is the version of the ST-Link utility? Can you perform a full chip erase using this tool?

Version 4.3.0 is current

also does not hurt to install the following:

STSW-LINK007 version 2.32.22

and

STSW-LINK009 version 2.0.1

Please reboot after the above and post your results of these updates.

​Hi Chris,

And you're sure that the Application Template you've based your appliaction matches the board you're trying to connect to?

Hi,

@Mon2 -> thanks for help, the updates (ST-Link Utility and Win10 driver) solved one big problem. Now I can Run Target Great....

@Martin -> The updates solves the "run target" problem now the simulator problem is left. After the updates I got an Message from Windows 10 when I start the Simulator: "You need a new app to open ms-gamingoverlay files" This I could solve myself. Everything works now! Thanks

Best regards
