Hi @goenjoy

I have followed step mentioned in the document, but our custom display supports only Non-Burst mode video operation with Sync Events and the continuous clock on clock lane.
so for this in the device tree, I need to provide in “dsi,flags” to generate sync Events and the continuous clock on clock lane. so what i have to set in dsi,flags in device tree can you help me to set this flags and generate clock on mipi clock lane.

I don’t see any problems. First, make sure the hardware is OK. DTS configuration is OK. Then this screen can be displayed normally.
