We have a 16-Bit TFT display connectet to OMAP-L138 and we are using the framebuffer device driver "da8xx-fb".
It's working fine and the command "fbset -i" shows the following informations:
mode "800x480-61"
# D: 37.501 MHz, H: 30.218 kHz, V: 60.558 Hz
geometry 800 480 800 480 16
timings 26666 128 250 1 14 63 4
rgba 5/11,6/5,5/0,0/0
endmode
Frame buffer device information:
Name : DA8xx FB Drv
Address : 0xc7000000
Size : 1638400
Type : PACKED PIXELS
Visual : TRUECOLOR
XPanStep : 0
YPanStep : 1
YWrapStep : 0
LineLength : 1600
Accelerator : No
We need the frambuffer in a 8bpp format.
With the command "fbset -depth 8" the display gets dark and we can't it get back with "fbset -depth 16"; we have to reboot the device.
Is it possible to configure the frame buffer device driver for a 8bpp (8 bits per pixel) format together with output lines for a TFT display with 16-Bit RGB signal lines?
