Tool/software:

I have an issue with bring up of sn65dsi83 IC. I used your tool and configured registers for test pattern, but can't get any image on the display. I'm checking 0xe5 register for errors, and there are no errors, previously I had error for PLL locking, but it is resolved now，What may be my problem, please explain in detail and give the solution, thank you!

When I use test pattern, DSI signal is not important, right?

Thanks

Hi,

I am sorry for the broken link, please see this link for the debugging guide. With the test pattern working, the LVDS output is ok. I am suspecting the line time is not matching between the DSI input and the LVDS output. The line time of the DSI input must match with the line time of the LVDS output, the debug guide shows how to check for the line time.

Thanks

David
