Use TouchGFX in N647

[sduer]

I found I can not config ToucgGFX to APPmode.It's seems I have to config EXTEM Loader first.I tried many management,but still fail to use TouchGFX in APP.I wonder if there's other way to use GFX.

By the way,I have to write the link files to fit in my HyperRam and Flash.Is there something to do with the"EXTEM Loader"and "EXTEM Manager"?

Thanks a lot!

Hello @sduer.

I don’t fully follow your description. Could you please elaborate a bit more and e.g. provide some screenshots?

One possible issue is that the Application context is not selected when you enable TouchGFX in STM32CubeMX. When you enable X-CUBE-TOUCHGFX, you are taken to the Software Packs Component Selector. There, you need to make sure that Application is selected in the drop-down menu at the top.

Best regards,
Johan

Thank you for answering.I've found if I allow cubemx to generate extmem loder file,it will generate TouchGFX app at the path "E:\.STM_project\N647\gfx_7\ExtMemLoader\TouchGFX".I am strugging to transport my fomer project,however,new MCU always means troubles.

Can you share your project?

I am still not completely sure what you are trying to do. Do you have a working TouchGFX project that stops working when you generate an external memory loader project? TouchGFX should definitely not be part of the external memory loader project.
