Would this be the cape you are using? https://wiki.seeedstudio.com/BeagleBone_Green_HDMI_Cape/
If you type 'dmesg' at the command prompt you should be able to see if there are any errors seen with the cape. I would double check the install of the cape as well. There is this note in the Seeed Studio forum though: https://forum.seeedstudio.com/t/re-the-hdmi-cape-for-the-bbg/251093 Cheers, Jon On Thu, Dec 24, 2020 at 4:26 AM LS-BBGreen <mystrato1...@gmail.com> wrote: > Hi all. > Recently bought a BB Green, and after a while ordered an HDMI cap for. > > Installed Debian 8.10 2018-02-01 4GB SD SeeedStudio IoT > <https://debian.beagleboard.org/images/bone-debian-8.10-seeed-iot-armhf-2018-02-01-4gb.img.xz>, > updated and upgraded: no video out on the monitor from the HDMI cap, since > the 1st boot not a character is displayed on the screen, the monitor says > ever and forever "NO SIGNAL". > > Btw the board is alive and normally managed by SSH. > > Tried to change dipswitches position on the cap to change the adress with > no luck. > Installed the jumper TP4 on the BBG and closed the pins, but no luck. > > Has anyone a solution or must sentence the brand-new cap as broken? > > Thanks for your support. > > Luigi > > -- > 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. > To view this discussion on the web visit > https://groups.google.com/d/msgid/beagleboard/f65a985b-444b-49de-b071-5b88e39f8b93n%40googlegroups.com > <https://groups.google.com/d/msgid/beagleboard/f65a985b-444b-49de-b071-5b88e39f8b93n%40googlegroups.com?utm_medium=email&utm_source=footer> > . > -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
