DS90UB941AS-Q1: DS90UB941+DS90UB948 splitter mode, but it has no display

Hello，

 One customer used the alternative line 3D splitter mode, but has no display. 

i2cset -f -y 0 0x16 0x4F 0x9C #alternative line


i2cset -f -y 0 0x16 0x5B 0x07 #splitter mode


i2cset -f -y 0 0x16 0x56 0x00

But it has no display, how to debug about it? 0x58 is 0x00.

Best regards

    Hi Kailyn, 

    Can I get more details? Can you share the complete configurations for all the devices (provide register dumps for all devices)? Are EVMs being used or are these custom PCBs? Has the customer used patgen function to verify the functionality of the 948 + displays and then the 941?

    Best,

    Shu
