I have a development board with i.MX8M processor from boundary devices. When the display is connected on HDMI interface via MIPI DSI to HDMI adapter, the processor could not identify it. The display is being identified on windows os. Also, the development board can identify other 1080p display.
Here is the link of board and linux os:

Can someone please help me identify and resolving the problem. Also, going through the other threads, I found that the processor is not able to work with non-standard resolution of Pixel clock. But not sure, how to resolve it.
Thanks and regards,
