Mixed image on screen

MHaji.1 · ‎2024-09-23

Hi,

I have a custom board with STM32H743 and working on a project by TouchGFX 4.24. When the device power on or reset, some times I have a mixed image including numbers, pictures and ..., which I attached the image... and some times every thing is Ok after reset or power on. I have another project by TouchGFX on this board, which it always works fine.

Please help me with this, thanks.

I should add, the main difference between program with distorted program and the correct one is: distorted program GUI is imported from old version of it from TouchGFX Designer... Is there any problem with this?

Please post the corresponding image of what the screen should look like.

Note that you can paste the image into the post - where we can see it - rather than attaching it (where we can't).

Hi Andrew,

Thank you for reply.

As you see in the picture, The numbers are readable and the picture is correct, but in last one all screen is distorted.

Thanks

Could this be uninitialised data?

ie, in your first case, the values are "junk", and this corrupts the display ?

PS:

especially if the data is passed via pointers, and it's the pointers that are uninitialised

No, The corrupted one is installed on a mold machine and the numbers are related to device, Here is a picture with the same as last pic which I sent:

As you see, There are some weird lines and numbers are corrupted, picture has lot of noise and...

Is it working on the same MCU part number i.e. STM32H743?

I have 3 different project which are almost have same content, but with a different user (different devices).. I have no problem with 2 of them, but the one which we speaking about has this problem, after power off and power on, the problem will solved, but in another power on, I face this corrupted state..

PS:

The GUI is imported from its old version in corrupted image device...
