您好!
我们的设计方案如下,出现问题是屏幕接在948-1口就可以正常点亮,接在948-2就电不亮且在948-2口一直在显示红、蓝和白的颜色跳变,请帮忙看看是什么问题?
测试过把DSI0和DSI1交换,还是948-2无法正常显示DSI的输出图像,只显示红、蓝和白的跳变;

Can they send me a video of the red, blue, and white changes?
Can they also please provide the initialization script they are using?
Are they doing SER PATGEN?
If they are doing SER PATGEN, I think it's because 941as Port 1 is programmed to output a different pattern generation than 941as Port 0.
Register 0x64 and 0x65 changes the type of pattern they want to display.
So what could try to do is
board.WriteI2C(seraddress, 0x1E, 0x06) #select Port 1
board.WriteI2C(seraddress, 0x64, 0x95) #enable color bar PATGEN
board.WriteI2C(seraddress, 0x65, 0x4)
If it's a distortion doing end-to-end video,
- I want to confirm, does SER PATGEN work? Does each individual DES PATGEN work?
- Have they tried switching the DES and see if it follows the DES?
BTW, this is just a good resource to have to bring up the 941as.
