Hi,
I received my DVI-D cape (s/n: 1412DVID375) as goes with my Beaglebone (Rev A5. S/N: 0812BB000176) last week (purchased through Farnell).
Next I moved to your latest Android release (ICS 4.0.3 with devkit 3.0.1) as available from: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_ICS_4_0_3_DevKit_3_0_1/index_FDS.html
To get me quickly up (just to see if all is OK) I downloaded the pre-built Android images for the above configuration (which tells me that DVI-D is supported on Beaglebone.
Booting the device goes OK, and I also see the DVI init messages coming by (see below):
My problem / issue as of now is, I tried with various LCD monitors (also different HDMI-DVI cables), but none of them seems to be working fine. It is the fact that the "Android" boot animation screen is displayed in a flickering way with strike through's in text (~1sec "ANDROID" next few seconds black screen). In the end, I get a black screens where only one monitor is capable to display some part of the Android desktop (initial screen) and even then, only in a flickering way. More in detail, this one monitor gives me a screen which is only now and then visible (tens of seconds black screen, next 1-3 seconds I see the Android desktop :-(
An other related observation I did, when I do not connect any (mouse / keyboard) USB device, I even do not get any Android screen ad all (only the "Android" boot animation screen popping now and then up).
When testing with the pre-built Linux kernel only (so not Android), I get the blue Angstrom login screen (http://beagleboardtoys.com/wiki/index.php?title=BeagleBone_DVI-D) etc as it should be via the DVI interface !!
Please, advice. I was wondering, how to change the video mode, or what else could I do?
Btw., I'm located in the Netherlands (50HZ).
Regards, Frank.
