Hi!
I am running Qt app on the dm8148 processor, and having trouble with low quality PNG images.
I configured the VPSS and FB with:
firmware_loader 2 dm814x_hdvpss.xem3 start
modprobe vpss sbufaddr=0xBFB00000 mode=dvo2:1080p-60 debug=1
modprobe ti81xxfb vram=0:24M,1:16M,2:6M debug=1
echo "Configuring fb0 to LCD"
echo 1:dvo2 > /sys/devices/platform/vpss/graphics0/nodes
echo 0 > /sys/devices/platform/vpss/display1/enabled
echo 33500,800/164/89/10,480/10/23/10,1 > /sys/devices/platform/vpss/display1/timings
echo triplediscrete,rgb888 > /sys/devices/platform/vpss/display1/output
echo 1 > /sys/devices/platform/vpss/display1/enabled
echo 1 > /sys/devices/platform/vpss/graphics1/enabled
fbset -xres 800 -yres 480 -vxres 800 -vyres 480
fbset -depth 32 -rgba 8/16,8/8,8/0,8/24
cat /dev/zero > /dev/fb0
cat /dev/zero > /dev/fb1
The pictures of the PNG are with low quality on the LCD.
Why is that?
