STM32H573I-DK display with ST7789 not working (blank)

[chrenderle]

Hello together,

I have the STM32H573I-DK which has a 240x240 ST7789 Display with 8016 Parallel transfer. I want to use the display with mipidsi and I could verify that the display was working because the demo firmware was using it. Sadly the demo firmware source code is not freely available so I couldn't compare it.

I tried all the steps in the troubleshooting section but it still doesn't work. I also checked that all the pins are correct multiple times. I don't know what I can do else to get it to run.
