Hi all,<br>
<br>
I have a custom board with a MPC5121e (rev 1.5) on it. It is the latest
git <br>
kernel from denx ads5121 head with our BSP mixed in.<br>
<br>
I decided to try out Application Note AN3793 from Freescale (3D Graphics
on <br>
the ADS512101 Board Using OpenGL ES).<br>
<br>
I started trying to load the provided (binary!) kernel modules into our
<br>
kernel, but I am geeting errors inserting the modules using <br>
insmod: 'clcdc.ko' complains about not being able to register de device
major <br>
number, and 'dbgdrv.ko' oopses with a BUG() in percpu_modfree()! This <br>
function should never be called in a non-SMP kernel, so I suspect there
are <br>
some important differences between the kernel I have and the one the <br>
binary-only drivers where built against :-(<br>
<br>
In another approach I managed to load the provided kernel binary (which
is <br>
built for the ADS512101 evaluation board) on our platform, by tweaking
our <br>
device-tree until it booted without crashing. In the end I was able to
load <br>
all the modules and run the OpenGL-ES demo programs.<br>
I can't believe this is the intended way of doing this, so I'd like to
know if <br>
there is someone else who has managed to get the MBX running OpenGL-ES
on a <br>
custom board with a custom build of the kernel.<br>
<br>
Note: the kernel version number is still the same: 2.6.24.6, only difference
<br>
AFAIK is some minor unrelated patches to drivers for other MPC5121 SoC
<br>
devices, and probably some different configuration options. Apparently
this <br>
is enough to break binary compatibility for the drivers :-(<br>
<br>
Any hint is appreciated...<br>
<br>
Best regards,<br>
<br>
