DMA2D causes hard fault in lv_draw_stm32_dma2d_blend_fill() function

[DWWelch]

I found the problem with the lv_draw_stm32_dma2d_blend_fill() function. You need to add the following to the DMA2D configuration in the function to prevent the hard fault:

DMA2D->OPFCCR = LV_DMA2D_COLOR_FORMAT;

Thank you for pointing it out!

Could you send a pull request?

I see that being done here and a few other places in _lv_draw_stm32_dma2d_blend_fill. Is there a place where it was left out accidentally?

[liamHowatt]

Oh I see, it's correct in LVGL release/v8.4 but not the submodule version of this port. Maybe we can use the latest version of v8.

Oh, nice! I think we should do this:

• create a release/v8.4 branch
• create the release/v9.0, release/v9.1, release/v9.2 branches. Hopefully in v9.2 we will have your new DMA2D driver.

I'll do it when testing this DMA2D of v9.
