AM3354: no /dev/input when using arago-tiny-image

Shine
Genius 13655 points
Part Number: AM3354


Hello Champs,

Hardware: AM3354 own board

Software:  PROCESSOR-SDK-LINUX-AM335X  06_03_00_106

When using arago-base-tisdk-image、tisdk-rootfs-image，it can find dev/input folder and there is tchscreen0 file in the folder

root@am335x-evm:~# cat /proc/bus/input/devices
I: Bus=0000 Vendor=0000 Product=0000 Version=0000
N: Name="ti-tsc"
P: Phys=
S: Sysfs=/devices/platform/ocp/44e0d000.tscadc/TI-am335x-tsc.0.auto/input/input0
U: Uniq=
H: Handlers=event0
B: PROP=0
B: EV=b
B: KEY=400 0 0 0 0 0 0 0 0 0 0
B: ABS=1000003

But when using arago-tiny-image, there is no /dev/input and there is no output after executing cat /proc/bus/input/devices command

root@am335x:~# cat /dev/input/touchscreen0

cat: can't open '/dev/input/touchscreen0': No such file or directory
root@am335x:~# cat /proc/bus/input/devices
root@am335x:~#

Thanks.

    Hello,

    I apologize for the delayed response. As per the Filesystem documentation and threads File system differences and Tiny filesystem support, the tiny filesystem is primarily intended for debugging, though it could be used as the base for a focused, headless usecase. It removes large parts of the regular filesystem, including the kernel modules for touchscreen.

    I do not have a bunch of experience with tiny filesystem, but in your SDK it looks like docs/licenses/arago-tiny-image-am335x-evm-BUILDNUMBER/package.manifest has some information about what is different between that and the other filesystems (e.g., docs/licenses/tisdk-rootfs-image-am335x-evm-BUILDNUMBER/package.manifest). I can see kernel-module-ti-am335x-tsc listed in the tisdk-rootfs-image manifest, but not in the arago-tiny-image manifest. And that matches the kernel modules in tisdk-rootfs under lib/modules/4.19.94.../kernel/drivers/input/touchscreen.

    Regards,

    Nick

    But when I use the file system and Linux kernel provided by other companies, there is / dev / input. When I replace the kernel with Ti SDK, there is no / dev / input. Is this also related to the Linux settings

    Hello,

    Have you tried tisdk-rootfs-image instead of the smaller filesystems? That is the complete filesystem image.

    Regards,

    I try tisdk-rootfs-image,but it doesn't show images 

    when I try  arago-base-tisdk-image，I can‘t port tslib to it

    My goal is to enable the system to use QT normally, and I'm still trying  to complete it

    Hello,

    In the thread that you linked above, the last picture shows 2013.02 arago project. However, if you are using PSDK6.03, it should show 2020 arago project. Could you please share how you are creating the base image?

    Because it was impossible to take photos at that time, we chose to use similar pictures on the Internet，and I chack it 。the filesysterm is the lastest 2019

    Hello,

    I just wanted to confirm that you are using the default images that come from PSDK 6.03 (ti-sdk-rootfs-image-am335x-evm.tar.xz). If yes, please share more details about your display configuration. Is it a LCD or HDMI and have you made any changes to the SW configuration? Also, how many data lines are you using for the display connection?

    Regards,

    Hello,

    Thank you for sharing the additional information. Since you are operating in 16bit mode, please review the following document: http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Foundational_Components/Graphics/AM3_Beagle_Bone_Black_Configuration.html.

    • /etc/powervr.ini: add DefaultPixelFormat=RGB565
    • /etc/weston.ini: add gbm-format=rgb565 at section [core]
    • /etc/profile.d/qt_env.sh: add export QT_QPA_EGLFS_INTEGRATION=none

    Also, since the blue-red wiring is swapped, please update the following section based on your HW connection. On the BBB, we have a 16bit interface and we set the blue/red wiring to straight. Ref Link: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm/boot/dts/am335x-boneblack-common.dtsi?h=ti-linux-4.19.y#n73

    There is no /etc/powervr.ini file. So I create the powervr.ini file. 

    about the  blue-red wiring ，I let the screen display pictures, my settings can display normal colors

    I made all the changes mentioned，But it still shows "please wait".

    Hello,

    I am wondering if you could please share the full boot log because I do not see any messages about wayland, matrix-gui or gpu services. Also, please trying running the command "/etc/init.d/rc.pvr start".

    Regards,

    Krunal

    Hello,

    I will check internally and get back to you. Also, besides the LCD, have you modified anything else in the drivers or filesystem?

    Hello,

    I am internally discussing the logs that you previously provided. In the meantime, I am wondering if you have access to a TI EVM and if possible, could you please try running the same targetfs on our board.

    Regards,
    Krunal

    I don't have ti EVM here at present.

    I checked it again. Because my board doesn't have audio playback requirements, the audio part in the driver has been shielded

    Hello,

    Thank you for sharing the dtb file. Based on my initial debug, I do not see any nodes related to SGX (our GPU). Here is a reference that you are missing in your file:

    Hello,

    Based on the new weston logs, I do not see any pvr errors. I am wondering if you could please try running the commands:
    /etc/init.d/rc.pvr stop and /etc/init.d/rc.pvr start. Also, try running kmscube and share the outputs. 

    Regards,

    Hello,

    It seems like Weston is running but not displaying any images. Please try running the command "/etc/init.d/weston stop" and try the above commands again.

    Hello,

    Okay, the GPU and the display is now working as expected. With regards to Weston, it seems like a format mismatch based on the log "format 0x36314752 not supported by output LVDS-1". I apologize for sharing incorrect information earlier but it seems like your display only supports "BG16 RG24 XR24". Please remove the below items and try again 

    • /etc/powervr.ini: add DefaultPixelFormat=RGB565
    • /etc/weston.ini: add gbm-format=rgb565 at section [core]

    Regards,
    Krunal

    Thanks.It work.but touchscreen isnt work.

    I check :

    root@am335x-evm:~# hexdump /dev/input/touchscreen0 
0000000 b366 5e9b 9e17 0006 0003 0000 0242 0000
0000010 b366 5e9b 9e17 0006 0003 0001 0c0d 0000
0000020 b366 5e9b 9e17 0006 0003 0018 0101 0000
0000030 b366 5e9b 9e17 0006 0001 014a 0001 0000
0000040 b366 5e9b 9e17 0006 0000 0000 0000 0000

    The system receives the signal from the touch screen，then I try to recalibrate screen：

    root@am335x-evm:~# rm /etc/udev/rules.d/ws-calibrate.rules   
root@am335x-evm:~# rm /run/media/mmcblk0p1/ws-calibrate.rules
rm: can't remove '/run/media/mmcblk0p1/ws-calibrate.rules': No such file or directory
root@am335x-evm:~# reboot

    After I click the red cross to calibrate,  click the icon still has no response

    Hello,

    It seems like the martix GUI is not being responsive to touch and we are currently debugging it. As an experiment, if you disable the gui and launch /usr/share/qt5/examples/touch/fingurepaint, are you able to draw?

    Hello,

    Are you planning on using Qt for your touch application or are you trying to verify the touch aspect of your LCD? Please provide more information about your end goal.

    Hello,

    I am internally discussing the touchscreen issues on AM335x and I will get back to you. With regards to display issues, I am wondering if everything is now functional. I guess you were just missing the GPU node in the DT file.

    Regards,
    Krunal

    Thank you ,the display issues is OK.

    I were just missing the GPU node in the DT file.
