OGLES libs mpc5121

moidom — Tue, 18 May 2010 15:01:04 GMT

Hi,

According AN3793 (3D graphics on the ADS5121..), OpenGL sdk, and OpenGL ES libs are provided with the app note... I found the SDK in the freescale sources but not the libs (I didn't found them in ltib either)

AFAIK, there are people on this forum using them. Does anybody know how to get them?

Regards,

Moises

Ok, sorry, the libraries and modules come with the ltib.

Now, my problem is that when I start the service I have an error regarding modules loading:

I think problem is owing to modules were compiled against a different kernel. I am using ltib (kernel 2.6.24) with the modules that come with the ltib ( pvr.ko, dbgdrv,..)

Has anybody successfully load the pvr service with the ltib version 'Release 1 20090603' ?
