PSDKLA 3.01 , Vayu ES 2.0 Rev H - External HDMI Touch Screen Display Support

Kaushal
Intellectual 690 points

I'm running PSDKLA 3.01 on Vayu ES 2.0, Rev H EVM.


I need to connect and external HDMI touchscreen display. When  I connect the display to the HDMI connector along with the USB input for touch, the external display only shows the weston background, but not the Matrix GUI.

The display in question is Lilliput HDMI multi touch display:


What should I do so that the external display shows Matrix GUI and touch works? In other words, I want to make the external HDMI display my default touch screen display.

Thanks,

Kaushal

    Hi,

    I am checking internally. In the meanwhile, using dra7-evm.dtb should enable only the HDMI display and matrix-gui will show up on HDMI.

    Thanks Venktat. The external display shows only weston background not Matrix GUI. However, if I drag a running app from Vayu default display to the 2nd HDMI display then I see the running app on HDMI. However, the  touch controller not working via HDMI USB.

    I assume you are using the split cable for HDMI + USB listed in the link you posted. Do you see any additional USB or input devices on the EVM when you connect the USB cable to the EVM?

    Venkat, yes. I'm using the HDMI USB split cable. The USB device won't show up automatically. Once I do modprobe g_zero then it shows up. Please see the command output below.

    You need to modprobe <gadget module>, because the USB1 port is configured for DRD mode (dr_mode = "otg" in arch/arm/boot/dts/dra7-evm.dts file). for host only configuration set dr_mode = "host".  In DRD mode, the port can act as host or device.

    Did you compiled kernel with touch screen driver support for this device.

    Menuconfig->Device Drivers->Input Device support -> Generinc input layer -> TouchScreen -> "EETI eGalax multi-touch panel support".

    This should help.

    We are still checking on how to start matrix-gui on a specific screen.

    Ravi -

    No, I didn't compile the Kernel. I use the prebuilt filesytem that came with the release 3.01. I was hoping this touch controller would be supported by default. Also, I'm not sure how to make the external display as default in config. Our plan is to use only the HDMI with the J6 Vayu EVM.

    "Menuconfig->Device Drivers->Input Device support -> Generinc input layer -> TouchScreen -> "EETI eGalax multi-touch panel support"."

    I am not sure what this means since I haven't build Kernel before. Where can I find this? Is that some kernel config utility?

    Thanks,

    Thanks Venkat. Please let me know when you have an update and supporting the touch controller without rebuilding kernel.

    You need to git clone the kernel repository, before building kernel issue the below command to chose the necessary config for kernel. Refer to User's guide for development setup and building kernel.

    $ Make menuconfig

    Ravi,

    As per the PSDKLA SW user guide, I tried to rebuild the kernel to make the our specific HDMI touch screen work. However, when I do "make linux" as per the  guide,  it doesn't give me any option to do  menuconfig. It just starts building the kernel.  Here's what I tried -

    $ cd $PSDKLA3.01
$ make linux_clean
$ make linux

    So, then I did this to do menuconfig

    $cd $PSDKLA3.01/board-support/linux

    $make menuconfig

    I configured the EETI touch screen driver as you described and then did "make linux"

    $cd $PSDKLA3.01

    $make linux

    But  it overwrote the file created by "make menuconfig" and replaced with PSDKLA default .config file without the touchscreen driver.

    How can I enable the driver?

    Thanks,

    Kaushal

    Kaushal,

    If you do "make linux" from the root of the Processor SDK - Linux Automotive installation, it will configure linux with the default configuration. This results in overriding the config file you created. The kernel config fragments used for generating the default configuration are in "board-support/linux/ti_config_fragments". I would suggest you add the configuration option you want at the end of "auto.cfg"  and run "make linux" from the root of the SDK installation. You can find the config option you use from menuconfig.

    "CONFIG_TOUCHSCREEN_EGALAX=y" should be the line to add at end of auto.cfg.

    regards,

    Venkat

    Hi Venkat,

    Thanks for help about modifying the auto.cfg file. However, It seems "CONFIG_TOUCHSCREEN_EGALAX=y" is not the correct config option for my display. I followed the instructions  provided by the driver update guide on EGalax website (driver package -  eGTouch_v2.5.5814.L-ma) and it worked. As per the document from Egalax, these are the driver changes in make menuconfig -

    Necessary:
    1. EVDEV

    2. UINPUT
    3. HIDRAW ( USB Interface )
    4. HID_MULTITOUCH ( USB Interface & Kernel 3.0 upwards )

    Remove:
    CONFIG_TOUCHSCREEN_USB_COMPOSITE ( For USB Interface & PID 0001 controller ) 

    Once I rebuilt the kernel using above changes, the touchscreen was detected.

    root@dra7xx-evm:~# cat /proc/bus/input/devices 
    I: Bus=0019 Vendor=0001 Product=0001 Version=0100
    N: Name="gpio_keys"

    B: PROP=0

    I: Bus=0003 Vendor=0eef Product=c000 Version=0210
    N: Name="eGalax Inc. eGalaxTouch EXC3146-1934-05.00.00"
    P: Phys=usb-xhci-hcd.1.auto-1/input0

    B: EV=b
    B: KEY=400 0 0 0 0 0 0 0 0 0 0
    B: ABS=2608000 3

    Now, the touch input is sensed. If I do "cat /dev/input/event1", I can see the raw touch input data on the console.  However, the HDMI display just shows 'Please Wait...' and nothing else. I tried "/etc/init.d/weston restart", but nothing.

    In short, touch screen worked but weston disappeared. Anyway to fix this and also getting the Matrix Gui on HDMI display?

    Thank you for your hep,

    Kaushal

    Hi,

    Glad to know that you were able to configure the kernel correctly.

    We have moved to systemd as the init system. Can you try doing "systemctl status weston" and share the result? When you built the kernel, did you build the graphics driver as well? This should be the case if you are using "make linux" from the root of the SDK. Have you copied the kernel modules you have built to the target filesystem? If there is a kernel version mismatch, the omapdrm_pvr module required for SGX usage will not start. Can you please share output of "lsmod"?

    regards,
    Venkat

    Hi Venkat,


    Yes. I did rebuild the kernel from PSDKLA root. As you had suggested, I added the following lines at the end of the file ti-processor-sdk-linux-automotive_dra7xx-evm_03_01_00_03/board-support/linux/ti_config_fragments/auto.cfg

    CONFIG_INPUT_EVDEV=y
    CONFIG_INPUT_UINPUT=y
    CONFIG_HIDRAW=y
    CONFIG_HID_MULTITOUCH=m

    And rebuilt and installed the kernel as -

    $cd ti-processor-sdk-linux-automotive_dra7xx-evm_03_01_00_03
    $make linux
    $echo $EXEC_DIR
    /media/patel/rootfs
    $sudo make linux_install
    As you can see I did the install in the rootfs partition, so I'm hoping everything got copied to SD card.

    Is it possible that weston & matrix gui don't come up at boot since I've to do "modprobe g_zero" after boot up to detect the USB touch controller? Please see the attached boot log for details.


    Thanks,

    Kaushal

    Hi Kaushal,

    I dont think the modprobe g_zero is an issue as it is only for the touchscreen. Weston needs a pointing device to start. It need not be a touch screen. It can be a mouse as well. You can use the unmodified kernel and connect a usb mouse to the EVM and check that weston starts. In this case, you can also check if there is pvrsrvkm module in the module list.

    You can repeat the step with a modified kernel. I am suspecting the pvrsrvkm module probe failed due to kernel version mismatch and weston is failing to start. If you do not find pvrsrvkm in the list, please make sure that all kernel modules are copied correctly to the SD card and that you do a "sync" on the host before unmounting the sd card. "/etc/init.d/rc.pvr" is the file you should look at to see if pvrsrvkm.ko has been probed.

    You may see a white screen after weston starts. That could be weston waiting for calibration. You can move the mouse or touch screen to get it to work.

    regards,
    Venkat

    Hi Kaushal,

    Could you try the below change?

    In Weston script /etc/init.d/weston, before launching runWeston, add a loop to wait for touchscreen to be available.
    Showing code snippet below for reference...


    if [ ! -d "$XDG_RUNTIME_DIR" ] ; then
    mkdir --parents $XDG_RUNTIME_DIR
    chmod 0700 $XDG_RUNTIME_DIR
    fi

    //Add a do while loop to check for touchscreen0 to be available

    openvt -c 4 -f runWeston

    # If there's no touchscreen device available, done
    if [ ! -e /dev/input/touchscreen0 ] ; then
    exit 0
    fi

    Hi Venkat,

    You were right, when I did make linux_install pvrsrvkm.ko wasn't being copied to /lib/modules/4.4.23-dirty/. So I created a directory extra at /lib/modules/4.4.23-dirty/ and manually copied pvrsrvkm.ko from build location /ti-processor-sdk-linux-automotive_dra7xx-evm_03_01_00_03/board-support/external-linux-kernel-modules/omap5-sgx-ddk-linux/eurasia_km/eurasiacon/binary2_omap_linux_release/target there.

    Booted the board

    root@dra7xx-evm:~#modprobe g_zero

    root@dra7xx-evm:~#/etc/init.d/weston stop

    root@dra7xx-evm:~#/etc/init.d/weston start

    root@dra7xx-evm:~# /etc/init.d/matrix-gui-2.0  start

    And it worked. I can see weston & matrix on the HDMI display and the touch works. So thank you.

    Santosh (Jha) mentioned he just spoke to you. I still have some questions to make the platform ready for CES and was hoping you could help with that. If you think it's faster you can email me at kaushal.patel@dts.com or should I continue posting here?

    Thank you,

    Kaushal

    Hi Vishal,

    Thank you. I didn't have to while loop (please see my previous response). I modified one of the scripts to load "modprobe g" and now it works.

    Thanks,
    Kaushal

    Kaushal,

    Our preference is to keep the discussion on e2e. However given the timeline for CES and roundtrip time for responses, we can have a call to answer your queries quickly.  We can close this thread if your original questions at the start of the thread are answered.

    regards,

    Venkat
