Simulator is not able to compile even after regenerating from the cubemx interface and then generating with the touchgfx designer.

These errors are shown as to be alleviated when the cubemx regenerates, but it hardly behaves as such.

I have regenerated both cubemx version 640 and touchgfx 420

Hello @rohan_m​,

Could you try to generate with 4.21.0 or 4.20.0 and let me know if you still have those issues.

Thanks,

Yes I just evaluated these images and can confirm that the images that are using the RGB565 and L8_RGB565 are not working. L8_RGB8888 images are working I can confirm that.

And yes I am generating this with 420 version

Could you delete your Middlewares/ST folder and regenerate code in Designer, and then try again please ?
