  • 4DCape LCD Blank screen after loading Android on BeagleBone Black

    As already described in the title, I'm trying to play an Android system on my BBB. It works well so far, I haven't connected to an HDMI yet, but I can get into the console with an FTDI cable. To all this I wanted to connect a 4DCAPE-70T LCD. I got the Android system from Andrew Henderson, who assures me that the Android video on the BBB should work out of the box. My screen is black, no sign of life. As an aside, I have to say that the screen works with the Debian on the BBB. I had also tried the releases from TI i.e. Jelly Bean, but the effect there is the same, nothing. But I have a snippet from the moment after the kernel starts where it has something to complain about the LCD. Can this somehow help to solve my problem?

    Hi, for everyone who struggles. I was wrong about the model of my LCD, it is the new versio the gen4, so the available Android releases wont work .. for now at least.
