Building a UGL v1.2 Display Driver

Note
The following instructions produce a bootable disk that automatically starts the UGL demo
software. These instructions assume that the Wind River Tornado platform is correctly
installed.
1. Create a working directory and unzip the UGL display driver into it.
2. Configure for the target execution model.
3. Build a boot ROM image.
4. Create a bootable disk (in drive A:).
5. If necessary, generate a new mode0.h configuration file.
For the example steps where the drive letter is given as “x:”. Substitute “x” with the
drive letter your development environment is on.
Rather than simply replacing the original config.h file, rename it so the file can be kept
for reference purposes.
Using a command prompt or GUI interface create a new directory (e.g. x:\13505).
Unzip the file 13505ugl.zip to newly created working directory. The files will be un-
zipped to the directories “x:\13505\8bpp” and “x:\13505\16bpp”.
This example build creates a VxWorks image fits onto and boots from a single floppy
diskette. In order for the VxWorks image to fit on the disk certain modifications are
required.
Replace the file “x:\Tornado\target\config\pcPentium\config.h” with the file
“x:\13505\8bpp\File\config.h” (or “x:\13505\16bpp\File\config.h”). The new config.h
file removes networking components and configures the build image for booting from
a floppy disk.
From the Tornado tool bar, select Build -> Build Boot ROM. Select “pcPentium” as
the BSP and “bootrom_uncmp” as the image.
From a command prompt in the directory “x:\Tornado\target\config\pcPentium” type
The file mode0.h contains the register values required to set the screen resolution, col-
or depth (bpp), display type, active display (LCD/CRT), rotation, etc. The mode0.h,
included with the drivers, sets the display for 640x480 60 Hz output to a CRT display.
If this setting is inappropriate then mode0.h must be regenerated. The configuration
program 13505CFG can be used to build a new mode0.h file. If building for 8 bpp,
place the new mode0.h file in “x:\13505\8bpp\File”. If building for 16 bpp, place the
new mode0.h file in “x:\13505\16bpp\File”.
