The build step produces two library images:

• lib/disputil/nto/x86/libdisputil.so

•  lib/disputil/nto/x86/libffb.so

For the loader to locate them, the files need to be renamed and copied to the lib directory. 

1. Rename libdisputil.so to libdisputil.so.1 and libffb.so to libffb.so.1.

2. Copy the files new files libdisputil.so.1 and libffb.so.1 to the directory /usr/lib.

3. Copy the file devg-S1D13708.so to the /lib/dll directory.

To locate the file devg-S1D13708.so, watch the output of the ‘true’ command during the
makefile build.

4. Modify the trap file graphics-modes in the /etc/system/config directory by inserting 

the following lines at the top of the file.

io-graphics -dldevg-S1D13708.so -g640x480x8 -I0 -d0x0,0x0;#640,480,8 Epson

io-graphics -dldevg-S1D13708.so -g640x480x16 -I0 -d0x0,0x0;#640,480,16 Epson

It is recommended that the driver be verified before starting QNX with the S1D13708 as 
the primary display. To verify the driver, type the following command at the root of the 
Project source tree (gddk_1.0 directory).

util/bench/nto/x86/o/devg-bench -dldevg/S1D13708/nto/x86/dll/devg-S1D13708.so -
mW,H,C,F -d0x0,0x0

Where:

W is the configured width of the display
H is the configured height of the display
C is the color depth in bpp (either 8 or 16)
F is the configured frame rate

This command starts the bench utility which will initialize the driver as the secondary 
display and exercise the drivers main functions. If the display appears satisfactory, restart 
QNX Photon and the restart will result in the S1D13708 display driver becoming the 
primary display device.
