I have initialized the MIPI DSI controller, and I can see the clock, data and other waveforms through the oscilloscope, but the logo still cannot be displayed, what should I do?Through debugging, I found that the program called the Splash Screen part of the code, instead of LCD_LOGO.

My question is that Mipi Lane can measure the waveform, but there is no data. What should I do next?
