Intellectual 580 points

Hello All

We are using  udworks board for display.  hdmi0 is working (also in our own design with lvds it is working)  but hdmi1 is not working in udworks board plus in our design.

we treed the following to display color bar but it is not working.

echo 0 > /sys/devices/platform/vpss/display1/enabled                             

echo 38362,800/200/24/72,600/24/0/1,1 > /sys/devices/platform/vpss/display1/timings

echo triplediscrete,rgb888  > /sys/devices/platform/vpss/display1/output

echo 1 > /sys/devices/platform/vpss/display1/enabled                             


./mem_rdwr.out  --rd 0x4810a000

./mem_rdwr.out  --wr 4810a000 0x4402b013

Please help us to solve this issues.

    I'm not sure what your triplediscrete line is meant to be doing but if I were you I'd install some basic graphical demos on your target such as the DirectFB demos and see if you can get them working. Or try using dd to write 0xFF to your /dev/fb0 node directly and check if the screen turns white.

    Hello Ralph

    I tried with DD command it is not working. 

    some information about hdmi  we are having two hdmi interface  hdmi0 and hdmi1

      Hdmi0  is working without any problem. and also we haved converted from hdmi0 to lcd with some changes in software it is working.

    Hdmi1 is connected viva sii9022a. 

    when i am try to load sii9022a driver i am getting the following error as mention in prev message.  with dd command or with colorbar bit enable it is not working. 

    it is handing in the function sii9022a_write  where i2c function  is called.

    I am able to detect i2c address  the i2cdetect software. the i2c address for hdmi1 is 0x39.

    Regards

    When I posted before I couldn't see your second post.

    I think you need to debug the Linux driver. It's clearly at fault and shouldn't be crashing especially with a null pointer dereference! I can only suggest you look at the source code for the driver and insert numerous printk statements until you find which part of it is failing.

    It may also be worth looking at TI's Arago repository online to see if there is a more up-to-date version of the SII9022 driver available.

    Hello Ralph

    I am able to fixed the linux driver issues. Now i am able to load and unload sii9022a.ko driver files.

    I am not able see any information about edid. for hdmi1  ( for hdmi0 i am able see the information).
