Hello,
I use DM816xEVM with EZSDK 5.03 and I want to redirect an output to HDMI/DVI display.
I saw that sometimes the omapfb.vram=0:12M,1:12M,2:12M omapfb.mode=dvi:1280x1024MR-32@60 omapdss.def_disp=dvi parameters
are sent as bootargs, but it didn't help me.
What should I do?
Thanks.
Hi,
Have you checked the VPSS , HDMI user guides . The below link gives the default setup/configuration for graphics & video pipelines & also the steps/instructions on how you can switch/change them.

Hi Prathap,
Thank you for your quick answer.
I didn't explain myself properly. I want to be able to use input that comes from the keyboard added to my board,
instead right now I can only use the keyboard added to the host.
Hi Alla,
The understanding from your initial post was that you are facing problem with the display & switching the display to HDMI as you had mentioned about HDMI.
Now it looks like an USB keyboard issue. I do not work on USB but i see that users have got this working as per some thread below.
Have you checked the other threads. I see that users have got this working & provided some suggestions-

The reason for my initial post is that I want the display which is connected to my EVM will be defined as the default display (instead of display of the host) and than maybe
I would see the input of the keyboard attached to the EVM.
Did you try the suggestions in other threads where some users have got the USB keyboard connected to EVM working.
Also did you try with another USB keyboard? Do you see the keyboard device getting enumerated?
Attach the dmesg logs & also provide the PSP(kernel) version used so that users working on USB can take a look & respond to the issue.
I think what you are really needing to do is enable the frame buffer console.
This requires compiling the Kernel with this configuration option enabled.
The second part of the issue is then getting the keyboard working.

Framebuffer console need be enabled from the menu configure, you can choose either static or dynamic build for framebuffer console. CONFIG_FRAMEBUFFER_CONSOLE is the entry for framebuffer console in .config file.
If it is static build, once fb.ko is loaded, console output will be on the HDMI(/dev/fb0)
If it is dynamic build, load the fbconsole module after fb.ko.

Hi,I enabled Device Drivers -> Graphics support -> Console display driver support -> Framebuffer Console support (static build). When I recompiled the image and modules and loaded the ti81xxfb.ko, but nothing has changed. Any suggestions?
