Problems Cloning the LCD display to the HDMI output

Jared Falter
Prodigy 220 points

I've been able to run my program on both displays independently with the same timings, but not simultaniously.

Here is a snippit script that I'm running:

      
        modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 debug=1 i2c_mode=1
        modprobe ti81xxfb vram=0:24M,1:16M,0:6M
        echo 5 > /sys/devices/platform/vpss/system/tiedvencs

        echo 2:hdmi,dvo2 > /sys/devices/platform/vpss/graphics0/nodes
        echo 0 > /sys/devices/platform/vpss/display0/enabled
        echo 0 > /sys/devices/platform/vpss/display1/enabled

        echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display0/timings
        echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display1/timings

        echo 1 > /sys/devices/platform/vpss/display0/enabled
        echo 1 > /sys/devices/platform/vpss/display1/enabled

        fbset -xres 1366 -yres 768 -vxres 1366 -vyres 768

        fbset -depth 32 -rgba 8/16,8/8,8/0,0/0
        modprobe ti81xxhdmi

And this is the output I am getting:

FIRMWARE: Default memory configuration is used
MemCfg: DCMM (Dynamically Configurable Memory Map) Version :  2.1.1.1
FIRMWARE: Memory Configuration status : In Progress
FIRMWARE: 2 start Successful
Setting Timing
ti81xxfb ti81xxfb: failed to star.

open /dev/fb0: No such process
HDMI W1 rev 2.0
ti81xxfb ti81xxfb: failed to star.
./vpss.sh: line 65: can't create /dev/fb0: No such process

 

Is there somthing that I am missing?

Thanks,

    Which PSP release did you use?  Which platform did you use?

    Not all release and platform support

     The normal stes to setup cloning is below:

    1.load vpss moudle

    modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60 debug=1 i2c_mode=1

    2. set up the timing for both display
            echo 0 > /sys/devices/platform/vpss/display0/enabled
            echo 0 > /sys/devices/platform/vpss/display1/enabled

            echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display0/timings
            echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display1/timings
    3. setup the tiedvenc, there is no need to echo 1 > /sys/..../display#/enabled, 
            echo 5 > /sys/devices/platform/vpss/system/tiedvencs

    4. let the fb0 output to both display

            echo 2:hdmi,dvo2 > /sys/devices/platform/vpss/graphics0/nodes
    5. load FBDev driver, if fbdev.ko is loaded before timing configuraiton, then fbset -xres -yres need be used

            modprobe ti81xxfb vram=0:24M,1:16M,0:6M

    Thanks for the reply

    I'm using the ti-ezsdk_dm816x-evm_5_02_02_60 on a 8168 board. The psp verions for the linux kernal in the ezsdk shows 04.00.00.12.

    my script now looks like this:

         modprobe vpss sbufaddr=0xBFB00000 mode=hdmi:1080p-60,dvo2:1080p-60,hdcomp:180p-60 debug=1 i2c_mode=1

         echo 0 > /sys/devices/platform/vpss/display0/enabled
         echo 0 > /sys/devices/platform/vpss/display1/enabled


        echo Setting Timing
        echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display0/timings
        echo 75010,1366/50/77/30,768/7/19/5,1 > /sys/devices/platform/vpss/display1/timings


        echo 5 > /sys/devices/platform/vpss/system/tiedvencs


        echo 2:hdmi,dvo2 > /sys/devices/platform/vpss/graphics0/nodes
        echo loading ti81xxfb

        modprobe ti81xxfb vram=0:24M,1:16M,2:6M

    When I try to check settings with fbset after I run this script I just get an error saying ti81xxfb: failed to star.

    PSP 04.00.00.12 does not support cloning. It is supported in PSP 04.00.01.13 release.

    I downloaded the 04.00.01.13 version of the PSP compiled the kernel and its modules.

    With and without the patch that was provided on the download page of the psp verion i get the following errors when trying to insmod vpss.ko.

    insmod: error inserting 'vpss.ko': -1 No such device

     

    I've been following the Video Driver User Guide PSP 04.00.01.13.

    I have added notifyk.vpssm3_sva=0xA0000000 to my bootargs. Looking at other posts leads me to believe it my be related to this setting though.

    Could you tell which .xem3 was loaded, from your SDK release or PSP 04.00.01.13 release? they are different firmware and have different memory map(notifyk.vpssm3_sva and vpss.sbufaddr).

    Please provide your bootargs and steps to load .xem3 and vpss.ko

    I loaded the ti816x_hdvpss.xem3 that was in the hdvpss binary package on the PSP 04.00.01.13 page.

    My boot args are as follows:

        console=ttyO2,115200n8 rootwait root=/dev/nfs nfsroot=10.40.100.11:/home/jaredf/targetfs rw mem=128M earlyprink notifyk.vpssm3_sva=0xA0000000 vram=50M ti816xfb.vram=0:16M,1:16M,2:6M ip=dhcp noinitrd

    The steps i used to load the driver are:

        insmod syslink.ko

        ./slaveloader startup VPSS-M3 ./ti816x_hdvpss.xem3

        insmod vpss.ko sbufaddr=0xA0200000

     

    When I loaded the pre-compiled image of the kernel it didn't give me the errors when loading vpss.  I need to be able to recomple the kernel though.

    I went ahead and rebuilt everything from scratch and everything works now.

    HI,

    I am using kernel from TI816X PSP 04.00.02.14. Here while installing the vpss my kernel getting crashed. But the kernel is loaded. 

    My bootargs are:

    bootargs 'console=ttyO2,115200n8 rootwait root=/dev/mmcblk0p2 rw mem=256M earlyprink vram=50M ti816xfb.vram=0:16M,1:16M,2:6M ip=off noinitrd 
    notifyk.vpssm3_sva=0xA0000000'
    

    Here the below steps I did:
    

    

     insmod syslink.ko  (Syslink_02_00_04_83 release)
    

     ./slaveloader startup VPSS-M3 ./ti816x_hdvpss.xem3 (HDVPSS 01.00.01.33 release)
    

    insmod vpss.ko sbufaddr=0xA0200000
    

    After this I am getting below crashing message:

    Can anybody tell me what is the problem and help me how to insert vpss module.
