CMEM module fails to load

CMEM module fails to load

[Tomas Frydrych]

Hi,

I am trying to get the gstreamer-ti package to work, using the 
v2012.05-yocto1.2 tag of meta-ti and the current Denzil release; 
I am getting an error when the CMEMK module is getting loaded:

Loading kernel modules for gstreamer-ti... 
Running /usr/share/ti/gst/omap3530/loadmodules.sh

I have also tried the linux-mainline kernel, to be precise commit
b478431b3cb62dae735c26fa2dfd025ffbf0776c, but am getting the same
error. 

Is this a known issue?

Tomas

Only if you forgot to reserve a memory hole at boot.
