I want to control the device(DLPDLCR230NPEVM) with raspberry pi .After replacing config.txt file with the sample config which downloaded from the official website ,the color screen is always displayed and cannot be turned on when restarting the raspberry pi. I wonder if it has anything to do with the model of raspberry pi while Raspberry pi 3B+ is now used.Or anything else?
I have verified the DLPC230NP EVM board can work independently as shown in the picture.And i changed for Rasperry Pi 4.But the problem still exists.I followed the step in the user' guide.After I modified the config file and restarted the raspberry pi, the raspberry pi could not start normally. I don't know what the problem is.Or there is anything wrong in my process?
