Hello Everyone!

I am running TouchGFX with ThreadX. When I add a new object, TouchGFX does not display anything.
The settings for TouchGFX are as follows:

1. ThreadX

2.TouchGFX

3.TouchGFX Designer

I just created a box for the background.

TouchGFX is working well.

 

TouchGFX doesn't display anything when I add an image to this screen, as shown below.

Could you please give me some suggestions? Thanks in advance.

Hello @LeonSu.

Could you provide more details? E.g. on the following:

  1. Which (MCU are you using?
  2. Is it custom hardware or ST hardware?
  3. Are your images stored in internal or external flash?
  4. When you mention that TouchGFX is working well with the box in point 3 that means that the box is visible on the display when you flash the application, right?
  5. Have you tried to connect a debugger to see if/where the application stalls?

Best regards,
Johan
