I have BOE BP101WX1-400 display TFT board. I want to connect it to DragonBoard 410c. I don’t have driver, Display Specifications, and oncommand, and off command for the board. How Should I do it.

I have tried to follow DSI porting guide. but the patch for the Display is not available

#3

do you have the datasheet?

#4

Yes. But above things are not mentioned in it.

#5

Then you may be able to contact the vendor and ask for MIPI-DSI DCS on/off sequences, and optional pre/post sequences, id sequences, and timings/dimensions. You also need the timings like pixle clock, byte clock, front/back porch etc, . etc. Without those it becomes an impossible guessing game.

If you haven’t designed and built an adapter board yet (which you also need to convert from the DB410C connectors to the 40-pin connector of the display), you could also consider sourcing a display that is either already supported by a Linux kernel or one that has these sequences available.
