This file outlines the installation of the STPC video drivers.
These drivers are designed for the STPC hardware under version
1.12 of Photon.
The following four files are required for the STPC drivers.
Confirm the sizes for each of the files:
Pg.STPC 129682
Pg.STPCdc 123896
STPCbios.trap 76063
crttrap.list 271
Copy the files to a dos formated floppy, then place the floppy in the
board floppy drive
To start type the following QNX command:
# sin ver
This will tell you if Fsys.floppy and Dosfsys is running, if not type
these QNX commands:
# Fsys.floppy &
# Dosfsys &
Now your dos floppy is mounted as /dos/a
Back-up any existing files that would be over-written by these
new files.
example :
# cp /usr/photon/bin/crt/crttrap.list /usr/photon/bin/crt/crttrap.list.org
To copy from the dos floppy use the command:
# cp /dos/a/
& copy the files to the following directories
*IMPORTANT*: Copying the files to a DOS floppy changes the
filenames so you must ensure the files are copied to the exact
filenames below including case.
/usr/photon/bin/Pg.STPC
/usr/photon/bin/Pg.STPCdc
/usr/photon/bin/crt/STPCbios.trap
/usr/photon/bin/crt/crttrap.list
*IMPORTANT*:Check the file permission and ownership.
When transferring the files to QNX from a Windows system,
the permssions are typically changed.
Use the following command to change permissions to
match below:
#chmod 777 <filename>
-rwsrwxr-x root root Pg.STPC
-rwsrwxr-x root root Pg.STPCdc
-rwsrwxr-x root root STPCbios.trap
-rw-rw-r-- root root crttrap.list
You should now be able to change directories to the root ('/') of your
filesystem and run the following two commands from the command line:
# crttrap clear
# crttrap trap
NOTE: crttrap is a QNX utility used to detect the video driver.
You should now be able to run Photon using the STPC drivers.
From within the Photon Desktop, select the right button. A pop
up menu will appear and you can select Configure Display. Change
the resolution and photon will load the STPC graphics drivers.
The next time you enter Configure Display, the ST Microelectronics
driver will be listed.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
