Asking for the SN65DSI84 questions
Hi Team,
We started to bring up SN65DSI84 1 week ago.
Unfortunately, it is not successful to power on so far.
And, I found some question about power on sequence.
1. From recommended initialization sequence, all DSI input lanes including DSI CLK must be driven to LP11 state.
I’m afraid that our DSI only can output LP11 for DSI data lanes and DSI CLK keeps HS state. It doesn’t meet its requirement.
But, I checked recommended initialization sequence in SN65DSI85’s spec. It accepts DSI CLK in HS state and DSI data lanes in LP11 state.
Could we refer SN65DSI85’s initialization sequence shown below to bring up SN65DSI84?

2. From init seq1 to init seq4, all DSI input lanes including DSI CLK must be driven to LP11 state.
However, from figure 6, the drawing doesn’t meet from init seq2 ~4. Please help to check it again.
