MIPI DSI PLL failed to lock


#1

Hi,

MIPI clock is not generated. Following msg comes at boot time
DSI PLL failed to lock. How to solve this problem ?

clock not generated MIPI ?

When MIPI Lcd connect then MIPI clocks comes. I have required MIPI continuous clock & data.

please help.

Thanks

Did you ever solve this issue? I am having the same issue.
