Hi,
I have a original Beagleboard C3. I installed ubuntu following the instructions from
http://elinux.org/BeagleBoardUbuntu#Saucy_13.10
(I also upgraded uboot before). Now I try to use my DVI monitor.
I have tried the following in my uEnv.txt:
dvimode=omapfb.mode=dvi:1024x768MR-16 omapdss.def_disp=“dvi” vram=8M omapfb.vram=0:8M
dvimode=“omapfb.mode=dvi:1024x768MR-16@60”
dvimode=“omapfb.mode=dvi:1024x768MR-16@60 omapdss.def_disp=“dvi” omapfb.vram=0:4M,1:4M,2:4M”
dvimode=“omapfb.mode=dvi:1024x768MR-16@60 omapdss.def_disp=dvi vram=12M”
…
mmcargs=setenv bootargs console=${console} ${optargs} ${dvimode} ${kms_force_mode} root=${mmcroot} rootfstype=${mmcrootfstype} ${expansion} ${systemd}
…
but the screen always remains black. Only when I power the BB with USB the screen shows something (whole orange color). After 2 seconds or so the screen goes to sleep.
What can I do?

Does this attached patch help against:
GitHub - RobertCNelson/armv7-multiplatform (v3.13.x branch) ?

Hi,
RobertCNelson:
Does this attached patch help against: https://github.com/RobertCNelson/armv7-multiplatform (v3.13.x branch) ?
Will try that on monday. Thanks!
So I tried it. I patched the kernel, copied the zImage to the boot partition and the modules to the root partition:
root@arm:~# uname -a
Linux arm 3.13.5-armv7-x11 #1 SMP Mon Feb 24 01:44:44 PST 2014 armv7l armv7l armv7l GNU/Linux
root@arm:~# lsmod
Module Size Used by
videobuf_dma_contig 5015 0
videobuf_core 19896 1 videobuf_dma_contig
gpio_keys 8034 0
omap_aes 11951 0
rtc_twl 5731 0
uio_pdrv_genirq 3258 0
uio 8799 1 uio_pdrv_genirq
No DVI. When I try to load omap-vout I get this kernel messages:
[ 118.207397] omap_vout omap_vout: failed to init dss
[ 118.213134] omap_vout: probe of omap_vout failed with error -16
[ 118.213958] omap_vout:Could not register Video driver
Any idea?
I forgot the log. Attached.
Any idea?

Oh, I just need to remember to dig out one of my old C4's and bring it to
work.
There's two conversions going on between v3.2.x and v3.13.x
board file -> device tree
omapfb -> omapdss

Does your latest commit (https://github.com/RobertCNelson/armv7-multiplatform/commit/96bfe9ffffba5050cfad338cf9d0966ed8c91a5d) contains any fixes regarding this issue? As far as I see no, or?
Thanks - Robert
Did you test v3.14-rcX? From this thread it looks like only up to v3.13.x.

Sorry, no, my fault. I tested
Should I give 3.14 a try?

Hi Robert,

Did you found time for doing this?
