Qt application run on Sitrara board AM5749 touch perfomance issue.

parth123

Hello,
I have run Qt application on sitara board AM5749 then application touch performance is so bed some time my application random behavior. I have also install in tslib in sitara board AM5749 but touch performance does not improve so how can I solve touchscreen touch performance issue?

***I explain about application and board AM5749 details.

touch display model and board info:
Display : OSD101T2587-53TS more info https://www.osddisplays.com/TI/OSD101T2587-53TS_A.1.pdf
Board : AM5749 more info https://www.ti.com/product/AM5749

Application inside MouseArea use:

fillMode: Image.PreserveAspectFit
MouseArea
{
anchors.fill: alarmSoundPlusImg
onClicked:
{
// perform task for clicked by user ........... But touch performance is very slow (four to five time touch then single touch event work )
}
}
}

**tsLib configuration steps:

 root@am57xx-evm:~# export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/touchscreen0
 root@am57xx-evm:~# export TSLIB_FBDEVICE=/dev/fb0
 root@am57xx-evm:~# export TSLIB_TSDEVICE=/dev/input/touchscreen0
 root@am57xx-evm:~# export TSLIB_CONFFILE= /usr/local/etc/ts.conf  
 root@am57xx-evm:~# export TSLIB_PLUGINDIR=/usr/local/lib/ts
 root@am57xx-evm:~# export TSLIB_CALIBFILE=/etc/pointercal

*Qt 5.11 use in sitara board. Qt Application cross compile for the sitara AM57xx board.

*Qt Application design in QML and all Data mange in C++ class.

*Those Qt application run in host machine using then perform good(mouse clicked event performance are normal). My host PC 8GB RAM and 4 core processor.

My Sitara board am57xx Info using /proc/cpuinfo :

please need helpful.

Hi and welcome to devnet,

You are likely in the case where no volunteer of this forum worked with that board.

Things to do:

ensure that you have hardware acceleration enabled
check which QPA backend you are using
check that your base system has everything needed for hardware acceleration to be enabled

Thanks for replay.

as your request I am doing some changes in below file but my application start and killed.

create a file file /etc/powervr.ini

[default]
ParamBufferSize=200000000
MaxParamBufferSize=200000000

/etc/profile.d/qt_env.sh file is
#!/bin/sh

QT Environment Variables

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
export QT_QPA_EGLFS_KMS_CONFIG=/etc/qt5/eglfs_kms_cfg.json
export QT_QPA_EGLFS_INTEGRATION=eglfs_kms
export QT_QPA_EGLFS_ALWAYS_SET_MODE=1
export QT_WAYLAND_SHELL_INTEGRATION=wl-shell
export QT_QPA_EGLFS_DISABLE_INPUT=1
export QT_QPA_PLATFORM=eglfs

//set eglfs plugin

3)/etc/qt5/eglfs_kms_cfg.json file :

{
"device": "/dev/dri/card0",
"hwcursor": false,
"pbuffers": true,
"outputs": [
{
"name": "VGA1",
"mode": "off"
},
{
"name": "HDMI1",
"mode": "1024x768"
}
]
}

after running app give those error and killed

I do not own such a board. You should contact the company that builds them.
