Part Number: SN65DSI86-Q1

Hi TI teams,

The eDP lane assignment and lane polarity can be configured at the same time through 0x59 and 0x5A register. The connection is showed as below. Is it correct ？

Hello,

How are you setting registers 0x59 and 0x5A? As long as you keep the polarity the same at the output the above looks to be fine.

Thanks,
Zach

Hi Zach,

The 0x59 and 0x5A register setting are as below. We resign all of the eDP lane and swap the polarity of each lane except AUXp/n. Please help me to check the hardware connection.

Thanks,

Emily

The DSI86 register programming matches with your hardware design.

Thanks
