Tool/software: Linux
I'm trying to move the matrix from the touchscreen to the HDMI out display. I've found the Matrix User's Guide wiki section for "How to Switch Display From Touchscreen to DVIout with Matrix" but it does not help as most of the instructions are not applicable.
I'm using the prebuilt image am57xx-evm-linux-rt-04.03.00.05.img.zip.
The very first step fails:
First stop the matrix application by running the following command.
/etc/init.d/matrix-gui-2.0 stop
with
Stopping Matrix GUI application/etc/init.d/matrix-gui-2.0: line 41 start-stop-daemon: command not found.
Continuing along with the following steps:
The following set of commands will switch the display output from the LCD to the DVI port. The stale output from when matrix was killed will now be sent to the DVI port at 480p resolution.
echo 0 > /sys/devices/platform/omapdss/display0/enabled
echo 0 > /sys/devices/platform/omapdss/overlay0/enabled
echo "" > /sys/devices/platform/omapdss/overlay0/manager
echo "720,480" > /sys/class/graphics/fb0/virtual_size
fbset -fb /dev/fb0 -xres 720 -yres 480
echo "lcd" > /sys/devices/platform/omapdss/overlay0/manager
..........
.........
The directories outlined here:
i.e. /sys/devices/platform/omapdss/display0/enabled
don't exist in the linux kernel
/sys/devices/platform/omapdss/
driver/ power/ subsytem/
Are these for older kernels? What are the proper steps to switch the matrix display location?
