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


kernel command line:

console=ttyO2,115200n8 vram=48M mpurate=auto
omapfb.mode=dvi:1280x720MR-16@60 omapfb.debug=y omapdss.def_disp=dvi
root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait

Also tried 1024x768MR-16@60, and different vram sizes, without success.
