egl on beagleboard xM

egl on beagleboard xM

[Tomas Frydrych]

Hi,

I am trying to get native egl (i.e., without X) working on Beagleboard
xM, but without much success. I am using libgles-omap3 (4.05.00.03) the
kernel(s) and sgx drivers from meta-ti master; everything appears to
start fine (i.e., no errors reported from pvr-init or dmesg), but trying
run any of the gles tests / demos gives:

  'eglInitialize' returned egl error 'EGL_BAD_ALLOC' (0x3003)

I have tried both linux-omap 2.6.39 and linux 3.0.8, with same results.

Any pointers to what the problem might be would be much appreciated,

Tomas

Both of those aren't the default, so are you actually using meta-ti?!?

Hm, so which is meant to be the 'right' beagleboard kernel? The default
virtual provider in meta-ti beagleboard.conf is linux-omap, and based on
the priorities it seems to work out that 2.6.39 is the preferred
version. I am quite happy to try yet a different kernel, of course :)

(I am only using the kernel and related recipes from meta-ti.)

No, it isn't.

Try using the machine.conf as well:


koen@dominion:/OE/angstrom-v2012-05/sources/meta-ti$ git log --oneline -1
51617ea cloud9-gnome-image: same as cloud9-image, but with GNOME added to it

koen@dominion:/OE/angstrom-v2012-05/sources/meta-ti$ git grep PREFERRED_PROVIDER_virtual/kernel | grep beagle
conf/machine/beagleboard.conf:PREFERRED_PROVIDER_virtual/kernel = "linux"
conf/machine/beaglebone.conf:PREFERRED_PROVIDER_virtual/kernel = "linux-ti33x-psp"

Sorry, that was mean to say 3.0.28, and the gles does not work. Or is
that not the default kernel?
