[Gumstix-users] Trying to get SGX / OpenGL working on Gumstix Overo Fire

[Dwayne F. <djf...@gm...>]

Hi all,

I'm trying to get the SGX drivers/OpenGL ES working on the Gumstix Overo
board.  I'm basically following the steps as outlined in the guide for
BeagleBoard
(http://code.google.com/p/beagleboard/wiki/HowtoUseSGXunderAngstrom).

I've built the necessary libraries, and I believe that the configuration
settings from Step 3 are correct by default (Beagleboard boots with a
24-bit-per-pixel frame buffer option, which needs to be changed to 16-bit --
if I'm wrong about this somebody please correct me)

Where I'm getting stuck is Step 4: Installing the libraries on the angstrom
system.  The steps are outlined as follows:

    1* Do 'opkg install
/home/root/libgles-omap3_3.00.00.06-r5.1_armv7a.ipk'. This will install the
OpenGL/ES libraries onto your system.

When I try running 1*, I get the following output (I noticed that I get the
same error when I boot up the board, is this an issue with my current image?
I'm using the prebuilt omap3-desktop-image 0.92 from the gumstix page):

ERROR: Module omaplfb does not exist in /proc/modules
ERROR: Module pvrsrvkm does not exist in /proc/modules
Usage: insmod filename [args]
FATAL: Module omaplfb not found.
mknod: missing operand after `0'
Try `mknod --help' for more information.
chmod: cannot access `/dev/pvrsrvkm': No such file or directory
/dev/mem opened.

Configuring libgles-omap3-tests
Collected errors:
* Failed to download
http://www.gumstix.net/feeds/2008/ipk/glibc/armv7a/base/libc6_2.9-r33.1.3_armv7a.ipk,
error 404
* Failed to download libc6. Perhaps you need to run 'opkg update'?

(Running opkg update doesn't fix the 404 error, does anyone know where to
download libc6 from?)

Next is step 2*, Do 'opkg install
/home/root/libgles-omap3-tests_3.00.00.06-r5.1_armv7a.ipk'. This will
install the SGX Test programs.  Running 2* says the following (doesn't
appear to be a problem but I'm posting the full output I get just in case):

root@overo:~# opkg install
/home/root/libgles-omap3-tests_3.00.00.06-r7.1_armv7a
.ipk

Not downgrading package libgles-omap3-tests on root from 3.00.00.07-r9.3 to

Step 3* says: Do 'opkg install devmem2'. This will install a little utility
that will let you run the SGX at its normal speed of 110 MHz.

root@overo:~# opkg install devmem2

(This seems to be the same problem as before in step 1)

So while most of these seem like issues with finding the sources, there is
that initial error about missing certain modules.  Can someone help me out ?

Thanks!
