Hello, I tried porting Android 4.2.2 image provided by TI on BeagleBone Black. I used Serialdebug on BBB and able to communicate using Serial console. I was able to start VNC server on android and saw the android working remotely on my laptop. Now, the problem is I am not getting anything on HDMI out on my monitor except error message "Unspecified Signal, Check your hardware". Can anybody help me how to resolve this issue. I tried angstrom distribution on same hardware and able to view display on HDMI 1080p. Also I tried TI EZSDK 7.00 and even it is displaying on HDMI 720p same setup. I guess it is problem with android distribution, can anybody help me to try change the resolution using serial console. I have attached serial console data below. Regards |

You can find the code for this under drivers/video/nxp/tda998x_drv.c. The resolution structs start at line 295. The line you need to modify to use a different one is 603.
If you haven't already, clone the kernel using:
git://gitorious.org/rowboat/bbb-kernel
Hope this helps.
