Download, Build, Install, and Configure the MB8629x X11 Drivers
The MB8629x X11 Drivers are available as Free Software under GPL
You can either download and run the binary modules from the DENX FTP
or you can download the full source tree from the DENX CVS
and rebuild everything from scratch.
For correct operation of the Coral-P card with the Linux X11 drivers the jumpers on the card must be set as documented in Installing a Coral-P PCI Evaluation Board
- Download the following files from the DENX FTP server:
- Install the files on a
Debian GNU/Linux system as follows:
# cp mb86290_drv.o /usr/X11R6/lib/modules/drivers/
# cp libmb86290_fb.a /usr/X11R6/lib/modules/
# cp XF86Config-4 /etc/X11/
# cp zvideo /usr/local/bin/
# chmod 0755 /usr/local/bin/zvideo
Please use the following command to login on our public CVS
cvs -d :pserver:firstname.lastname@example.org:/cvsroot login
When prompted for the
just press the return key (empty password).
Please use the following commands to check out a copy of the MB8629x X11 Driver source code:
cvs -z6 -d :pserver:email@example.com:/cvsroot co -P x11_mb8629x
To build the drivers you must have the
The procedures of getting and unpacking these can vary
dependent on the type of OS which you are running.
If you use Debian Linux you can perform the following steps
to get and unpack the
"root") Make sure your package database is up to date:
# apt-get update
- (as normal user) Go to your chosen build directory:
$ cd Coral-P
- Get XFree86 sources:
$ apt-get source xserver-xfree86
- Go to the directory where the package sources has been downloaded;
the name of this directory depends on the version of
$ cd xfree86-4.3.0.dfsg.1
- Create the build tree (unpack the package):
$ debian/rules setup
'build-tree' will be created and the package will
be unpacked in it.
- Go to
'build-tree' directory and copy the contents of the
'x11_mb8629x' CVS tree on top of the
in the Debian
XFree86 build tree.
- Go to the
'xc' directory in the build tree.
- Set the
KERNELSRC variable of
to point to actual location of the MPC5200 Linux kernel sources.
- Comment out the line
'$(MAKE_CMD) $(MFLAGS) $(WORLDOPTS) World'
in the top-level Makefile in the 'xc' directory.
The line is located near the end of the
'World' in the following context:
$(MAKE_CMD) $(MFLAGS) Makefiles
$(MAKE_CMD) $(MFLAGS) BOOTSTRAPSUBDIRS= clean
$(MAKE_CMD) $(MFLAGS) includes
$(MAKE_CMD) $(MFLAGS) depend
# $(MAKE_CMD) $(MFLAGS) $(WORLDOPTS) World
@$(CC) $(VERSINC) -o $(VERSPROG) $(VERSSRC)
@echo Full build of XFree86`$(VERSPROG)` complete.
- Finally, to build the driver, execute the following commands:
(cd config/util; make)
(cd programs/Xserver/hw/xfree86/drivers/mb86290; make)
(cd programs/Xserver/mb86290_fb; make)
Just copy two modules to the directory with X11 modules:
# cp programs/Xserver/hw/xfree86/drivers/mb86290/mb86290_drv.o
# cp programs/Xserver/mb86290_fb/libmb86290_fb.a /usr/X11R6/lib/modules/
Now you have to edit the
file as follows:
- Add a new device section, something like:
Identifier "MB86290 card"
Option "Accel" "true"
- Modify the screen section; the device string has to look like this:
Device "MB86290 card"
If there are
'DefaultFbBpp' options - delete them.
There must be only one display subsection, and it has to look like this:
If you followed the instructions above to build the X11 driver, you can proceed to
build the demo video application as follows:
$ cd xfree86-4.3.0.dfsg.1/build-tree/zvideo
# cp zvideo /usr/local/bin/
There are some known limitations of the video capture software which you
need to be aware of:
- The video picture cannot be scaled down in one direction (for
instance, horizontally) and at the same time scaled up in the other
direction (for instance, vertically). It can be either scaled down in both
directions (i.e. made smaller), or scaled up (i.e. made bigger).
- The video picture cannot be overlapped by other windows. If this
happens, the video driver stops displaying video in the window.
- A scaled up in vertical direction video picture is of a bad quality.
These limitations are actually due to limitations of the MB86295 hardware.
We don't believe that they can be overcome in software.
