I am Korean and a developer with less than a year of experience. Please understand the immaturity of inquiring in the official English language. I am using STM32MP157C-EV1 board. The board has the following settings according to the blog link I referenced. The blog link address is : " http://www.emsyslabs.com/how-to-compile-linux-using-yocto-for-stm32mp1/ ". As you can see, the settings are as follows.
STM32MP157C-EV1
*Linux Image : OpenSTLinux -> st-example-image-qt
*DISTRO=openstlinux-eglfs MACHINE=stm32mp1 source layers/meta-st/scripts/envsetup.sh
As you see the anothe address link : https://wiki.st.com/stm32mpu/wiki/OpenSTLinux_distribution
"Image : st-example-image-qt is ST example of image based on QT framework "
That's right. I'm doing some development to test a Qt example on that STM32MP157C-EV1 Board. Luckily, referring to the blog link, I was able to test the qt example for the target board, including the toolchain.
" http://www.emsyslabs.com/how-to-compile-linux-using-yocto-for-stm32mp1/ "
But I'm having a hard time. When running the Qt example, it is running in portrait mode only, not landscape mode. How can I run the Qt example in landscape mode? To run in landscape mode, I tried two things.
One thing is the referring to the previous blog, image file created on the basis of eglfs. Modified the profile file in the embedded Linux /etc directory.
As follows in Bold
PATH="/usr/local/bin:/usr/bin:/bin"
EDITOR="vi" # needed for packages like cron, git-commit
[ "$TERM" ] || TERM="vt100" # Basic terminal capab. For screen etc.
# Add /sbin & co to $PATH for the root user
[ "$HOME" != "/home/root" ] || PATH=$PATH:/usr/local/sbin:/usr/sbin:/sbin
# Set the prompt for bash and ash (no other shells known to be in use here)
[ -z "$PS1" ] || PS1='\u@\h:\w\$ '
if [ -d /etc/profile.d ]; then
for i in /etc/profile.d/*.sh; do
if [ -f $i -a -r $i ]; then
. $i
fi
done
unset i
fi
# Make sure we are on a serial console (i.e. the device used starts with
# /dev/tty[A-z]), otherwise we confuse e.g. the eclipse launcher which tries do
# use ssh
case $(tty 2>/dev/null) in
/dev/tty[A-z]*) [ -x /usr/bin/resize ] && /usr/bin/resize >/dev/null;;

Second, I modified the qml file in the qtquick example. In the dashboard Qt example, I added the following x, y, and angle values:
Window {
id: root
visible: true
width: 1280/2
height: 720/2
color: "#161616"
title: "Qt Quick Extras Demo"
ValueSource {
id: valueSource
}
Item {
id: container
width: root.width
height: root.height
anchors.centerIn: parent
transform : Rotation {
origin.x: 420
origin.y: 610
angle:270
}
The first method was useless. The second method was displayed in landscape view as shown in the following image.
Again, I would like to ask you some great professionals here. How can I run the qt example in landscape mode? For more fundamental solution. Same thing as modifying the kernel. Like the kernel fix code below. CONFIG_FRAMEBUFFER_CONSOLE_ROTATION=y fbcon=rotate:3
However, I did not find it on st-image-qt. Even though I typed the following command: cd / && grep -r "CONFIG_FRAMEBUFFER_CONSOLE_ROTATION" /
That is all. Thank you.
