But it is just changing the size of the debian logo for 2-3 seconds and then screen turning to black again. I upgraded to linux 3.8.13-bone70 today from linux 3.8.13-bone41 just downloaded it ran ./install-me.sh then rebooted. I am working with two beaglebone black boards right now. One is perfectly running with lcd screen and hdmi cable without any modification to uEnv.xt file or something else. Both BBB boards have same kernel and os versions. I appreciate all your advice and help.
Are they 'exactly' the same versions? Including the u-boot version? I still think it's lucky one even works at full 1080p... > > Upol > > > > 29 Aralık 2013 Pazar 22:28:57 UTC+2 tarihinde Gerald yazdı: >> >> I assume you followed all the instructions on the Wiki, so I guess the board is bad.

I'm using a known-good micro-HDMI to HDMI adapter, and I've tried connecting it to a 1280x1024 monitor via a HDMI to DVI-D cable and to a 1080p TV using a straight HDMI cable. The TV knows there's something there (it disables inputs that are inactive, and it allows me to select the HDMI input to which the BeagleBone is connected) but says "No Signal," whereas the monitor just says "No Signal." >>>> >>>> I've tried both the preinstalled Angstrom Linux and the console version of Ubuntu 13.04 - no dice with either. I've got a proper micro-HDMI to HDMI cable arriving tomorrow, just in case there's something the BeagleBone Black doesn't like about the adapter I'm using (although I tested it on a Nokia 808 PureView, and it worked fine.) >>>> >>>> Anybody any ideas what might be preventing the BeagleBone Black from bringing up a display? I can see nothing in the kernel logs that sheds any light on the matter. It sees the virtual HDMI cape in Slot 6 and appears to load the firmware cape-boneblack-hdmi-00A0.dtbo fine. >>> >>> -- >>> For more options, visit http://beagleboard.org/discuss >>> --- >>> You received this message because you are subscribed to the Google Groups "BeagleBoard" group. >>> To unsubscribe from this group and stop receiving emails from it, send an email to beagleboard...@googlegroups.com. >>> For more options, visit https://groups.google.com/groups/opt_out. >> >> > -- > For more options, visit http://beagleboard.org/discuss > --- > You received this message because you are subscribed to the Google Groups "BeagleBoard" group. > To unsubscribe from this group and stop receiving emails from it, send an email to beagleboard+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/d/optout. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
